Bubble bag is a kind of degradable foam plastic. At present, there are many researches on polyhydroxybutyrate (PHB) and polyhydroxyvalerate (PHV. Fragments with lower molecular weight will further oxidize in the air, resulting in free radical chain breaking and further degradation to CO2 and water.

According to the degradation mechanism, degradable plastics can be divided into photo-degradable plastics, photo-degradable plastics with photosensitizers, biodegradable plastics and multi-functional degradable plastics compounded with a variety of degradable plastics. According to the conditions of degradable plastics, it can be divided into photo-degradable plastics, biodegradable plastics, fully biodegradable plastics, locally biodegradable plastics, chemical degradable plastics, oxidative degradable plastics, water degradable plastics, and composite degradation materials composed of the above three degradable plastics groups. Photodegradable plastics with photosensitizers are a few photosensitizers in the process of plastic processing. Because of the photoexcitation effect and photochemical reaction of photosensitizers, free radical excitation source occurs, Dongguan packaging materials can accelerate the photodegradation process of polymers. This plastic manufacturing method is simple and low cost. Photodegradable plastics can only be degraded under the premise of sunlight irradiation, which is limited by geographical conditions and weather conditions, so the widespread use of which is inevitably restricted. What are the characteristics of bubble bags? Bubble bag, also known as air cushion film, bead glue, bubble roll, etc., is made of low-density polyethylene. It is a kind of transparent soft packaging material widely used at that time, and is widely used. The principle of Dongguan packaging materials is to use the film including air to form bubbles to avoid the impact of products, ensure the maintenance effect when the products are shaken, and also have the effect of thermal insulation, which is suitable for the packaging or turnover of different products from all walks of life. Because the center layer is filled with air, the bubble bag is light and elastic, and has the functions of sound insulation, shock resistance and abrasion resistance. It is waterproof, moisture-proof and pressure-resistant.
