气泡膜 About Bubble Film
, 运用低密度聚乙烯加工而成，是当时遍及运用的一种通明软包装资料 , 用处广泛。 Bubble film, also known as air cushion film, air bead glue, bubble roll, etc. , is made of low-density polyethylene. It was a clear flexible packaging material that was widely used at the time and was widely used. The principle is that the film includes air to form air bubbles to avoid the impact of the product, ensuring the maintenance effect when the product is sensation, and it also has the effect of heat insulation, which is suitable for the packaging or turnover of different products in various industries. !! Because the middle layer of the air cushion film is filled with air, it is light and flexible, and has the functions of sound insulation, shock resistance and abrasion resistance. It is waterproof, moisture-proof, and pressure-resistant.
? Which side of the bubble film is better for shock resistance ?
Of course, the bubble is in outward contact with the plane of the box, and the smooth surface inside is in contact with the mailing object. Because if the bubble is facing inward, the object may be easily broken when it is in direct contact with the box from the bubble gap when there is a shock (there is an unbuffered site); if the bubble is outward, it is equivalent to forming a dense with the outer plane In the shock absorption layer, the internal objects are only stressed on the inner surface of the foam when the collision occurs, and the force will be dispersed to many bubbles to transmit the force.
