What are the bubble diameters commonly used in bubble films?

Bubble diameter: 6mm, 10mm, 28mm, 20mm (less common) and heart-shaped bubbles (with special shape and smaller compression resistance than circular bubbles) are the main types. The most common bubble diameter is 10mm, which has a wide range of compressive strength. 6mm is characterized by beautiful appearance and neat bubbles, which is suitable for products with outer packaging such as electric loom, mainly for wear resistance and incidental shock absorption. The bubble diameter of 20-28mm belongs to large bubbles, which is characterized by high bubble height and thick film thickness, and the best cushioning and shock-proof effect. 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 extrudes at a high temperature of about 230 degrees to form bubbles. 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. Also known as bubble pad. 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. 1960 was invented by American Mark Chawanart. I just want to design a new three-dimensional wallpaper. 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. Bubble film soon became a popular packaging material because it has the characteristics of shock resistance, moisture resistance and wear resistance. Later, because many people like to break the bubbles on the bubble film, the bubble film was given the function of relieving psychological pressure.
