The Evolution of Void Fill Packaging Materials

Posted By 4dmin on Mar 2, 2018 4:14 PM

Void fill packaging materials, an evolution
At the end of 2016, Amazon shipped 3 million packages a day. Chinese eCommerce giant Alibaba shipped an overwhelming 12 million packages per day (source). A more recent number from January 2018 for Amazon shows that the company shipped over 5 billion items worldwide through their Prime program (not including non-Prime sales) in 2017, although there is no breakdown of how many packages that entailed.

Both retailers have grown exponentially throughout 2017. While Amazon and Alibaba are the top two e-Tailers today, don’t forget to consider 2016’s “runners up” like Apple ($16.8 billion in online sales) and Walmart ($14.4 billion in online sales; source).

Considering the millions of packages traveling around the globe each day, you may take a step away from your amazement at the sheer number of goods being delivered and say to yourself, “Wow, the packaging materials industry must be booming right now!” Well, you’d be right to think so!

According to the Freedonia Group, a market research firm, eCommerce accounts for over 8% of total retail sales, and has made protective-packaging companies a $5.6 billion industry. The same group forecasted that US demand for air cushions alone was up by 5.5% at the end of 2016.

That’s right – air cushions. Which is actually the product that spurred the idea behind this article. If you’ve ordered anything online over the last five years, it’s likely that your package’s contents were protected by air cushions, and not packing peanuts or bubble wrap. So what happened? Let’s take a look at the history of some of the top void fill packaging materials, and compare the pros and cons of each type of protective packaging product.

Bubble Wrap History

heavy duty bubble wrapBubble wrap was actually invented prior to packing peanuts, which came as a surprise to this writer while doing research for this article. And you’d never believe that the actual phrase “Bubble Wrap” is a generic trademark of one particular company! Sort of like how Kleenex is a term used all the time to refer to facial tissue, Bubble Wrap is a name trademarked by one of the co-inventors of the product, who then co-founded a company called Sealed Air Corporation.

Bubble wrap was invented in 1957 by two men in Hawthorne, New Jersey: Alfred Fielding and Marc Chavannes. They had set out to develop a kind of 3D wallpaper, but as you might expect, this original purpose fell flat. They later determined that their failed wallpaper concept could be used as a wonderful form of packaging material, able to keep fragile products safe during transit. One of the inventors, Alfred, co-founded Sealed Air Corporation in 1960.

As most readers will be aware of, bubble wrap has different bubble size options. Wrap with larger bubble cells, or large bubble wrap, is used to protect bigger products (there is a specific product called heavy duty bubble wrap for heavier items), while smaller cells are used for smaller, lighter products.

You will find bubble wrap isn’t usually used as a void fill packaging material, but is used more commonly to wrap fragile items, giving them a 100% surround “air padding” (think about glassware and ceramics).

Pros & Cons of Bubble Wrap:

Bubble wrap is a wonderful way to pack fragile materials. It’s affordable and easy to source, even from consumer-focused stores like Home Depot, as many people use bubble wrap to protect breakable items during a move. The variation in bubble cell size and it’s lightweight profile also allow it to be used effectively in envelopes to protect thinner contents in the form of bubble wrap pouches. When shipping electronics, there is anti-static bubble wrap available, thereby protecting electronic chips from static electricity.

On the other hand, many forms of bubble wrap are not biodegradable, but can often be recycled. The drawback here is that most sheets aren’t marked with a recycling symbol, so much of it winds up in the trash can. It’s also not practical to use as void fill packaging, as the shipper winds up using a lot more bubble wrap material to fill a void space that would be better (and more affordably) filled by paper or air cushions. There are also storage considerations regarding bubble wrap, as the bubble cells are pre-inflated and take up valuable floor or shelf space.

Packing Peanuts History

styrofoam packing peanutsOn December 21, 1962, Robert E. Holden of Oregon filed a patent request for his invention called “loose fill packing material,” which was granted in 1965. Robert’s original patent application described his void fill product specifically as “loose fill packing material in the form of a plurality of expanded members of resilient thermoplastic foam which are made in an interlocking configuration in order to prevent relative movement between adjacent members.”

To manufacture his loose fill packing material, Robert developed a machine that produced said material. As explained in this article from Vision Launch (quoted also from Wikipedia):

“To facilitate the creation of the packing peanut, Holden also invented an apparatus that would help to cut and expand plastic members through a steaming process. By feeding plastic strips through the device, it would create the foamy cellular structure that is the trademark of the classic packing peanuts. It also allowed the plastic to be created in such a way that they would interlock, providing a more secure shipping solution.”

Holden noted in his patent that the packing material “provides the members with resilience so that they cushion against shock and vibration, and resist crushing or permanent deformation.”

Today, there are two main types of packing peanuts in production: Polystyrene foam peanuts, and starch-based biodegradable packing peanuts.

Polystyrene Packing Peanuts

Also called Styrofoam packing peanuts, these are based on Robert Holden’s original invention. Robert’s patent was purchased by the Dow Chemical Company in 1965. As such, Dow is widely seen as the inventor of the packing peanut, since they put it into commercial production. Since the 1990s, these previously “bad for the environment” packaging materials have been able to be recycled and reused. You can tell a recycled poly packing peanut from a virgin resin peanut by its color. Green peanuts mean the product is made from 70% or more recycled polystyrene, while white peanuts indicate they were made with non-recycled materials. Pink peanuts mean that an antistatic agent has been applied (source).

Starch-based Packing Peanuts

biodegradable packing peanuts
Also called biodegradable packing peanuts, these dissolvable loose fill packing packing peanuts were developed in the early 1990s. The “starch” that makes up these peanuts comes from crop-based sources (like corn starch) and is non-toxic. They can be dissolved in water and, yes, even eaten, although there is no nutritional content in them and they’ve not been prepared in food-safe conditions.

Pros & Cons of Packing Peanuts:

Poly peanuts are lighter than their starch-based counterparts, which means savings on shipping costs when comparing the two. Poly peanuts can also be recycled, although not as easily as starch-based peanuts. For poly peanuts, you’ll need to call your local recycling center to see if styrofoam packing peanuts are accepted. If they are not, you can try to “donate” your packing peanuts to a local shipper, as they might be able to reuse them. If poly peanuts are not recycled and simply thrown in the trash, they may wind up sitting in a landfill for many years.

Biodegradable peanuts, on the other hand, can be recycled by dissolving them in water and pouring used water down the drain. If you throw starch peanuts in the trash, they will biodegrade on their own over a short period of time. Aside from weighing more than poly peanuts, starch-based peanuts are usually more expensive to buy.

Major con of both kinds of packing peanut: They make a huge mess for the recipient of a package and take up a ton of space in your recycling bin!

Kraft Packing Paper History

kraft packing paperWhen talking about the history and evolution of void fill packaging materials, it wouldn’t be fair to focus only on packing peanuts versus air-filled products. Kraft paper as a packing material is in heavy use today in the eCommerce retail world, so let’s compare it’s history and values with other void fill staples.

As you may assume, plain brown paper was developed very early on, much earlier than any of its counterparts. The process to make kraft paper was developed by a man named Carl F. Dahl from Germany in 1879. Carl named his process the “kraft process” because the word “kraft” in German translates to “strength” in English, and the paper produced by this process was very strong compared to regular letter-type paper. The patent for Carl’s process was issued in 1884, and commercial production of kraft paper began in Sweden in 1890. Improvements were made to Carl’s process in the 1930s that allowed the entire process to be almost “closed loop,” meaning there was little to no waste, aside from some of the chemicals used.

Today, kraft paper is used not only as a void fill packaging material, but also as brown paper grocery bags, parcel wrap and butcher’s meat wrap. It can be purchased in either roll or sheet forms to suit your packing needs.

Pros & Cons of Kraft Paper (or Newspaper for the Non-Industrial Packer) for Packaging:

The major pro of packing paper is that it is completely recyclable, just like regular newspaper, and is also biodegradable. People can also re-use packing paper as kindling for their fireplace during the winter months (or bonfires throughout the summer).

Kraft packing paper also has the advantage of being able to get “smushed down” quite small to fill packing void spaces where an air cushion might not fit. Cost-wise, it’s cheaper to buy kraft paper versus air cushions, since the cushion material typically costs a bit more. Plus, for commercial scale air pillow applications, you’re going to want to invest in an air filling machine rather than filling the pillows by hand.

However, kraft packing paper also weights more than air pillows, causing your shipping costs to add up over time. Many shippers find that although the purchase price of paper may be cheaper to buy, they wind up saving hundreds of dollars a month by switching to air pillows. The other major drawback to packing paper is that, depending on the package contents, it can be squished down and flatted during transit (after absorbing many shocks and vibrations) to the point where it no longer offers proper protection for your goods. If you have people manually packing your boxes, you’ll also notice that they are likely to sustain more papercut-type injuries dealing with kraft paper than they are with air cushions.

Air Cushion Packaging

air cushion packaging materialFrom the 1950s to 2010, there have been many void fill solutions invented and commercialized, but perhaps none are as prevalent today as Sealed Air’s Void Fill Air Cushion packaging material. As the inventor of bubble wrap, Sealed Air’s bubble wrap business is now only 15% of its $1.6 billion protective packaging empire (source). Meanwhile, the company’s air cushion or “filled air” products are relied on by major retailers like Amazon, Home Depot, Walmart, UPS and FedEx.

We were unable to find an exact “birth date” for Sealed Air’s air cushion void fill products. The closest thing we could find was this article referring to “newfangled air pouches” dated September 2010.

Pros & Cons of Air Cushion Packaging:

Why have filled air cushions become so incredibly popular over the last six years? Pulling from the pros and cons of the void fill packaging materials reviewed above, void fill air bags provide a lighter shipping weight. They are safer to handle than kraft paper for employees working with these packing materials. They are definitely a wonderful, clean respite from the mess and disposal requirements of packing peanuts. The cushions are comparatively cheap to buy once an air fill machine investment has been made. They are easy to store and take up less space compared to bubble wrap (unless you buy pre-inflated cushions). And they fill a variety of void spaces efficiently and flexibly, thanks to their various sizing options.

They’re also recyclable, although depending on your area, you may have to bring them to a special recycling center, which causes some earth-friendly worries To combat this issue, some manufacturers have developed biodegradable air cushion packaging. Another drawback is that if a shipper isn’t using a box optimized for its product’s size (eg: a box that is too large for its product), numerous air cushion bags need to be used to properly fill the extra space. This exacerbates wasteful use of the cushions, and contributes to the recycling dilemma we mentioned.

Custom Packaging: Is It Worth the Investment?

Posted By 4dmin on Dec 13, 2016 5:33 PM

Custom packaging, including corrugated, available from Direct Supply in Elgin IL
As a company, especially startups and eCommerce websites, you have a limited amount of money that can be invested in different areas of your business. Some of these areas – like staff, product development, and sales – are extremely vital.

With seemingly more important areas of your operation to fund, it might be easy to argue that investing in custom corrugated packaging is not worth the cost, which can vary greatly depending on your needs.

However, it makes great sense for some businesses to consider an investment into custom packaging rather than purchasing standard packaging in bulk, even though there is a larger upfront cost.

To help you determine if it’s right for your business, we’ve put together some factors to consider so you can see how custom corrugated packaging can potentially help your business.

Improved Protection

One of the quickest ways to lose customers is by giving them a bad experience. While you might have a generous policy for replacing damaged items, consider that American consumers tell, on average, 16 other people about a bad experience. Additionally, 89% of consumers will choose a competitor for their next transaction after a bad experience, and it will take you 12 positive experiences to make up for one bad one.

Americans tell an average of 9 people about good experiences, and tell 16 (nearly two times more) people about poor experiences.

With those statistics in mind, making sure your products are well-protected when shipping should be a top priority. When you choose standard corrugated packaging, you get a one-size-fits-all solution that might not be the best fit for your products. You may find yourself sending out more replacements than you’d like, which not only affects customer relations, but also eats into your profit.

With custom corrugated packaging, you can choose the exact construction and additional protective packaging materials that meet your needs. Not only can you select a box size that is ideal, but you can also create internal sections and add padding where it is needed to protect the box’s contents.

Sometimes you need more than a box to protect your products. You may choose to go with edge protection for added security. However, if you are using standard corrugated boxes, even with the edge protection, it may not fit snugly enough and still end up breaking or damaged in shipment.

Custom packaging can also improve things like aroma or moisture retention, and prevent the contents of the packaging from exposure to the elements and other damaging factors. Other protective measures include stretch film, strapping, and bubble wrap.

Customized Experience for Consumers

With advancements in technology, it seems as if the entire shopping experience is customized for consumers. From the ads seen online to detailed customer demographics, the instant supply of information allows eCommerce and brick and mortar stores to deliver personalized information and products to their consumers.

The same customized experience can apply to your packaging, as well. With a better understanding of your market and what your customers need, you can customize your packaging to meet those needs. By choosing custom corrugated packaging, you can get the structure and look that you desire. This is especially important if you need to protect delicate products, or if you need to set yourself apart from your competition.

For example, have you ordered anything from Amazon lately? If so, did you notice anything special about the packaging tape they use on all their corrugated boxes? It’s custom-printed with timely marketing messages – from “Black Friday Sales,” to “Amazon Prime Video,” to “Alexa.” Packaging tape is a necessity when you’re shipping anything. Why not use it as a marketing vehicle, as well?

Custom Packaging Reduces Waste

When you use a box size that is not quite right, you end up having to use extra materials to pad the box to help prevent damage. With custom corrugated packaging, you can get a tight-fitting package that matches the product contents, which will help reduce waste and eliminate excess material.

One of the top desires of millennial consumers when they shop for products is choosing something with environmentally friendly packaging. By reducing waste and eliminated excess materials, you can offer a more eco-conscious option than standard boxes allow.

Create a Memorable First Experience

Research tells us that people form first impressions almost instantly. Thanks to the rise of eCommerce, the packages your customers receive will often be their first physical impression of your company. Custom corrugated packaging presents a unique chance to create a memorable first experience for your customers, making packaging more important than ever.

People place a lot of value in first impressions, and packaging is the first chance your eCommerce customer has to touch your product. Also, if your custom shipping boxes leave a positive first impression, they can increase expectations of the product itself. If you can deliver both exceptional packaging and product, your customers will enjoy a better overall experience.

To further impress customers, consider upgrading to visually attractive labels, as well.

Additionally, people around the world may be exposed to your packaging thanks to the rise of “unboxing” videos. These videos feature consumers recording themselves opening a product they’ve received, and many of them are viewed millions of times. In 2013, over six years’ worth of unboxing videos were uploaded to YouTube. If your packaging and product were ever featured in one of these videos, it could be excellent for your business if your custom packaging is attractive to viewers.

Save on Shipping Costs

With the introduction of dimensional pricing regulations from both UPS and FedEx, using boxes that are too big for your product can end up costing you quite a bit of money in shipping fees. The volume of packages being delivered is on the rise, so dimensional pricing was introduced to help parcel services be able to deliver more packages. By using boxes that are too big, delivery vehicles were starting to “cube out” before reaching their weight capacity, so this move will help more packages get to more customers.

When you think of custom shipping boxes, it’s not just branding that is custom. Customizing your corrugated packaging to the ideal sizes and levels of protection can help you save money on shipping costs in the long run. Instead of incurring extra fees because of the dimensions of your packaging, you can keep your packaging streamlined for a secure fit.

Enhance Your Brand

Apart from the packaging dimensions, you can customize many things about your corrugated packaging including color, style, and wording. Use the customization to help you stand out from the crowd. If you are using standard packaging, there is little to no brand differentiation between you and your competitors, and it makes it harder for customers to see what makes you unique. With custom corrugated packaging, you can achieve innovative results by appealing visually to customers and enhancing your brand.

While this is likely more prominent with eCommerce products, your packaging plays a big part in the perception of your brand for your customer. Since the only physical interaction with your brand is when the package is received, the packaging creates the user experience. A visually appealing design that reflects your brand can leave a much more positive, lasting impression than standard packaging.

When you have a strong brand value, your customers will become more emotionally connected with your business, and they will relate more closely to your brand. This emotional connection is essential to creating long-term success for your business. By investing in custom corrugated packaging, you are helping to facilitate the emotional connection with your customers, which is something you can’t get with standard packaging.


After taking a look at several ways custom corrugated packaging can help your company, it may be easier for you to answer the question of it being worth your investment. If your business is an eCommerce company, investing in custom corrugated packaging can be even more beneficial to you.

From saving money on shipping costs to reducing damaged items, you can see how custom corrugated packaging can affect your bottom line. Less tangible things like creating good experiences and enhancing your brand will show themselves long term in the form of increased sales and loyal customers.

If you are ready to make the investment for your company and move to custom corrugated packaging over standard packaging, the next step would be to call a company offering custom options, like Direct Supply, Inc. They should walk you through the process and talk to you about your shipping, packaging, product, and transit needs.

From there, you will likely receive recommendations and packaging options that work within your budget constraints and help you meet your goals. You will be able to choose from different custom packaging options, vendors, and packaging products – like stretch film and tape – to get the final product that will best work for you. The initial investment may seem daunting, but if your product could be shipped more efficiently, and you could use the brand enhancement, it may be worth your investment.
