These are made with a poly exterior and a poly interior/bubble layer. Typically they are made with a combination of HDPE #2 and LDPE #4 plastic and (unless they have foil or metalized plastic lining, which a small set does) can be recycled wherever grocery bags are accepted. Currently, most poly bubble mailers have no recycled content and are made with only virgin material.

EcoEnclose is proud to have released a line of bubble mailers with 50% recycled content. These are the most eco-friendly mailers on the market. In addition to their recycled content, they have a dual peel and seal and tear strip for reusability, are 100% recyclable and are Made in America.
Bubble mailers are complex to manufacture, and the construction and sealing process is susceptible to temperature and melting points and highly partial to the purity and consistency of virgin content. It took us a long time to get to this level of recycled content, but we&#;ve learned a lot. We are moving forward from here, constantly pushing up recycled content levels with each iteration to eventually get to 100% recycled content.
You may have found other recycled bubble mailer options if you&#;re looking for eco-friendly bubble mailers. We dug into these options as we developed our recycled bubble mailer and learned that their claims could be vague.
If you see a recycled mailer that claims 5%, 10%, and 30% recycled content, it is likely the case that &#;up to X% of the outer layer of the mailer&#; is made with recycled content. If this is the case, it would mean that the outer layer has an arbitrary amount of recycled content, based on what the manufacturer had as scrap from their recent production runs. More than likely, the bubble and capping layers (internal) of the bubble mailer are made with only virgin poly. Given this, a mailer stating 30% recycled content would have between 0% to 16% recycled content when looking at the entire mailer, and you wouldn&#;t know the exact recycled content in the particular bag you purchase get.
When looking for recycled bubble mailers, we recommend asking suppliers for a breakdown of recycled content by layer within their mailers. Confirm that the recycled content is consistent and verified, and consider asking them where their product is manufactured. These questions may sound like overkill, and we know companies aren&#;t typically trying to make misleading claims! They often take the information they receive from their supply chain at face value without asking hard questions. Because the supply chain for most items (especially packaging) starts in Asia, it is often impossible for them to verify claims. Finally, while the Federal Trade Commission has excellent guidelines for Green Marketing, there aren&#;t certifying bodies that verify recycled content claims (in the same way there are for things like Certified Organic and Certified Compostable). It is up to consumers to ask these hard questions to ensure sustainability innovation is genuine rather than greenwashing.
Newark, NJ shipping and packing company Mailers HQ is known for its variety of shipping products, including mailers. All of the company's mailers are available in a range of sizes and come with discounted prices for bulk orders. The company is committed to excellent customer service and ensuring that clients get the mailers that they are looking for. The company has now announced the release of its latest blog post titled, 'Poly Bubble Mailers vs. Kraft Bubble Mailers', to explain the difference between the two popular types of mailers.
Goto Huanyou to know more.
A spokesperson for Mailers HQ says: "As a company looking for an ideal packaging material, you will factor in the type, shape and size, the weight, level of protection and the cost. The shape, size and weight will also have a bearing on the actual cost of shipping so they are as important as the padding or cushion and other protective attributes such as prevention of scraping, scratching and denting, as well as moisture. You may be a tad perplexed with the two most commonly used packaging materials of the day: poly bubble mailers and kraft bubble mailers."
The blog post points out that both poly and kraft bubble mailers have their own pros and cons. The exact shipping needs have the greatest influence in terms of choosing between the two. How large the goods are, their shapes, how much they weigh, and how fragile they are, are all factors that need to be taken into account in terms of choosing the type of mailer. Meanwhile, other elements are equally important. The Mailers HQ spokesperson explains: "Other factors that need to be considered include color, printing, recyclability, closure or sealing, protection against moisture, weight, rigidity and freight costs, all of which will be influenced by your choice of packaging material."
The blog post goes on to explain some of the particular pros and cons of both types of envelopes. For instance, it highlights the fact that the unique and natural appearance of kraft bubble mailers is one of the things that make them so popular. On the other hand, it is more difficult to customize kraft mailers. Poly mailers are able to show true colors, something that can be important if businesses want to print their logo or other details on the envelope. With kraft paper, true colors cannot be shown due to the golden hue that is typical of kraft. The spokesperson says: "If you want custom colors and printed designs, then poly mailers are more appropriate."
Another element that the blog post considers is how to recycle bubble mailers. This is an important issue because many people are now committed to sustainability. It is pointed out that while both kraft and poly are recyclable, recycling kraft is more complex. The representative explains: "In the case of kraft, the paper needs to be separated from plastic, which is what the bubbles are made of. While both are recyclable, kraft has a more extensive process." This issue is mainly due to the fact that kraft is made up of both paper and plastic, which need to be separated. On the other hand, kraft usually has a greater recycled content than poly, which means businesses have to determine for themselves which one would be more suitable with their own green agenda.
The blog post goes on to explain that both poly and kraft mailers can be effectively sealed and cannot be tampered with. However, a poly mailer can be fitted with an anti stat release liner, which customers can peel off and that won't cling to the package. While generally not an absolute necessity, it does often make it easier to package certain types of goods.
A downside of kraft, as the blog post explains, is that it is not moisture resistant and may therefore be wholly unsuitable for certain goods. On the other hand, kraft offers greater protection than poly due to its high profile bubbles. Hence, for fragile items, kraft mailers are certainly the best option. The spokesperson points out: "The bubbles are taller, offering more rigidity. This comes at a cost though. The larger bubbles of kraft increase the freight cost. You can practically load almost twice the volume of kraft bubble mailers onto a truck if you choose poly bubble mailers."
Because of the increasing popularity of bubble mailers, Mailers HQ has increased its stock of both poly and kraft mailers. A variety of sizes are available and custom mailers can also be created. Those interested may contact the company for a quotation, particularly if they wish to place a bulk order of mailers as those are available at a discounted price.
