1. Bubble film is a product which uses high-pressure polyethylene as the main raw material, and then adds auxiliary materials such as whitening agent and opening agent, and then forms bubbles around the longitude after high-temperature extrusion. It is a new plastic packaging material with light texture, good transparency, non-toxic and tasteless, which can play the role of moisture-proof, buffering and heat preservation for products. Bubble film is also called air cushion film, air bead film, bubble cloth, bubble paper, bubble film, bubble film and air cushion film. It is a pressure-resistant, moisture-proof and shock-proof chemical product, which is used for packaging and filling. It has the advantages of good shock absorption, impact resistance, good heat sealing, non-toxic, tasteless, moisture-proof, corrosion resistance and good transparency.
2. 1960 was invented by American Mark Chawanart. One day, when he was on the plane, he saw the clouds outside the window. He thinks clouds are used to protect the plane from landing safely. Inspired by this, he made a plastic bubble film. Because of its shock-proof, moisture-proof and wear-resistant characteristics, later, because many people like to squeeze bubbles on the bubble film, the bubble film was given the function of relieving psychological pressure. Today, Seagate, the patent owner of bubble film, has more than 65,438+0 and 70,000 employees in 52 countries and regions, and earns more than $4 billion from bubble film every year.
