气泡膜又称气垫膜、防静电气泡袋等等,使用低密度聚乙烯加工而成，是当前普遍使用的一种透明软包装材料,用途广泛。
Bubble film, also known as air cushion film, anti-static bubble bag and so on, is made of low density polyethylene. It is a transparent soft packaging material widely used at present.
其原理是以薄膜包含空气使之形成汽泡来防止产品撞击，确保产品受到震动时起到保护作用，同时亦有保温隔热的作用，适合各行各业的不同产品包装或周转之用。由于气垫膜中间层充满空气，所以体轻，富有弹性，具有隔音，防震、防磨损的性能，它防水，防潮，抗压。
The principle is that the film contains air to form bubbles to prevent product collision, to ensure that the product plays a protective role when it is shaken, at the same time, it also has the function of heat preservation and insulation, which is suitable for packaging or turnaround of different products in all walks of life. Because the air cushion film is filled with air, it is light, elastic, sound-proof, shock-proof and wear-proof. It is waterproof, moisture-proof and compressive.
