As a result of their similarities in appearance, co-extruded film and pearlescent film can be hard for the untrained eye to tell between. The simplest approach to tell if a film is co-extruded is to look at the color difference between the inner and exterior layers. If the inner and exterior layer of the film is not the same color, then most likely it is co-extruded film.

In addition, co-extruded film is more elastic, whereas pearlescent film is inelastic and simple to peel off. Co-extruded film releases an unpleasant smell when it burns, but pearlescent film does not and occasionally even has a faint fragrance. 

During production, co-extruded film could be made with a certain portion of recycled materials, while pearlescent film could not.

6. Material and size of air bubbles

Air bubble wrap is produced with high pressure polyethylene together with whitening agents and other auxiliaries under the heat up to 230 degrees. These lightweight and transparent bubbles come with advantages like moisture-proofing, buffering the goods inside from shocks or damage during shipping.

A bubble typically has a diameter of 6 to 10 mm and a height of 2 to 3 mm. The higher the bubble, the better it is at absorbing hits during handling, allowing for a lot of shock absorption.

7. Self-sealing function and material of release film

Ultimate guide to bubble mailers explain how bubble mailers can be self-sealing, which saves time and labor and is one of its most appealing qualities. Simply place your products inside, remove the adhesive strip, and seal the package, and you are ready to go! Because of its sturdy structure, it not only ensures a solid seal but also helps keep privacy throughout shipping. Mailers with a self-sealing feature provide greater convenience and excellent value.

The strip you remove when sealing the bag is called a release liner. Three materials, including paper, polyethylene, and aluminum foil, are typically utilized in the release liner for bubble mailers.

Polyethylene release liners must be treated with an anti-static coating in order to prevent static adsorption, which could harm the customer’s experience. The most expensive release liner is made of aluminum foil, but it’s still a wise choice as it has a luxurious appearance.

For the sealing part of the mailer, you can choose to have it made with or without the bubble wrap layer. Although it saves materials to make it without the bubbles, it reduces the production efficiency.

8. Technique processes of bubble mailer

Have you ever wondered why some bubble mailers are bumpy and others are smooth? Everything depends on their manufacturing technique. The former uses “foaming” while the later doesn’t. Foaming bubble mailers has better shock resistance and visual appeal, but the cost is relatively higher.

It is not recommended to make foaming bubble mailers for aluminum foil film and laser film with the weight below 160g, or co-extruded film below 85g. Because it may lead to a lack of aesthetics as well as the creation of bubbles within bubbles. It may even lead to a poor lamination of film and air bubbles resulting in an air leakage.

9. Are bubble mailers customisable?

The use of bubble mailers is revolutionizing how businesses interact with their clients and creating new potential for impact. In addition to catching people’s attention, colorful packaging often features creative designs with logos or other distinctive branding that elevate customers’ experiences with your goods.

This is a really useful tool for managing enduring client connections and cultivating loyalty. These upgrades make your items stand out from the competition and ensure that your consumers will remember you long after their packages have been delivered.

10. Tips on bubble mailer design?

A. No printing on adhesive area

It is essential to leave that adhesive area plain. In addition to saving you money on printing expenses, it will also guarantee that your seal is as strong as ever because ink will not affect its sticking power. Remember to provide an extra centimeter when calculating the size of the closed flap so that your design is not buried behind when it is tightly sealed.

B. No printing on left and right edges

Because cutting machine variations could occur, it is advised against placing graphics all the way to the left and right edges. When mailer bags are frequently cut continuously, it is possible that designs assigned to one side of a mailer bag can end up on the side of the following mailer bag.

Another concern is that bubble mailers often have edges that are between 1 and 1.5 cm wide. High temperatures that press the edges together could result in color loss or white areas. To protect your mailer bag design from these undesirable situations, make sure there are no patterns or colors on either side of the mailer’s crimping edge.

C. Patterns better not reach the front and rear sides' bottom edges

On the front and rear sides of mailer bags, it is advised against placing designs at the bottom edges. This is because little adjustments to the machine’s operation during folding could result in a slight movement of the patterns. Hence, designs that were intended for the front side may end up on the back side instead, or the reverse. Designers must always be aware of these potential changes and take the appropriate safety precautions while creating mailer bags.

D. Eye Mark

Please be advised that finished bags frequently feature a small black line strip called an eye mark or locator mark in the center or corner. This part, which can be seen on the mailing bag, helps automatic cutting machines identify the precise areas that need to be trimmed. As a result, even though it may not have been a part of your mailer bag design, this component is essential to the production of mailer bags.

11. Are bubble mailers reusable and recyclable?

Yes. Bubble mailers are a great solution to save packing expenses and promote sustainability because they can be reused. To make it simple to open and reuse these mailers, double self-sealing strips and easy-tear lines on the mailer bags have been developed.

While still offering a sturdy layer of transit cushioning, reusing bubble mailers also removes the need for the cost of acquiring additional repackaging materials. In conclusion, by recycling bubble mailers wherever possible, you may both save money and protect the environment.

After being reused for several times, a bubble mailer could eventually be recycled. Bubble mailers need to be delivered to the specified recycling collection facilities in order to be recycled.
