Nowadays, e-commerce has become part of our everyday life, we buy everything we need online wait until the package is shipped in front of our door. During the package delivery, air bubble film becomes a crucial part to make sure our items are not damaged.
What is Air Bubble Film？
Air Bubble film also known as air bubble wrap, it is made of high-pressure polyethylene as the main raw material, adding whitening agent, opening agent, and other auxiliary materials, it provides superior protection for items in transit.
Bubble wrap can be found in various sizes and levels of sheets making it a great option for a wide variety of packaging needs.
Why air bubbles film is important?
Air bubbles film forms air bubbles through the film containing air to prevent the product from impacting, ensuring that the product is protected, and also has the effect of thermal insulation. The production process of the bubble film has great help to our packaging. During the production process, the middle layer of the bubble on the surface of the bubble bag is filled with air, so it is light in weight, elastic, and has the properties of sound insulation, shock resistance, and wear resistance. Not only that air bubble film is waterproof, moisture-proof, and pressure-resistant, it is very helpful for reducing vibration during package shipping In the production process of bubble bags, we should also pay attention to the selection of materials, and try to choose some materials that can withstand high temperatures, so as to better guarantee the safety of product packaging.
So, how air bubble film was made?
You might be surprised to learn that bubble wrap begins life as tiny beads of resin, almost like grains of rice. Several different resins are used for their different properties and these are combined into the material, and produced by air bubble film machine.
The tiny resin beads are melted down together at over 450 degrees Celsius, where they combine and form into a thin film which is the base material for making bubble wrap. This film is then flattened to the required thickness before being fed through rollers with small holes in.
As the film travels over these rollers, air is vacuumed onto it, pushing it into the small holes which create the air bubbles that give it such good protective qualities.
With the air bubbles blown into the film, it’s then run across more rollers which seal it with another layer of film, trapping the air inside and ensuring that the small air bubbles stay contained.
Finally, it’s cut to width and perforated so it can be rolled up into large, industrial-sized rolls. After passing quality checks, it’s then shipped out to be used all around the world.

Next, the film is flattened to the desired thickness and fed through rollers. These rollers have small holes which vacuum air onto the film to form air bubbles. Once the air is blown into the film, it is fed through more rollers and sealed with another layer of film. Once the second layer of film traps the air, the bubble wrap is cut, perforated, and rolled into large rolls of industrial-sized bubbles.
