Bubble bag is a kind of biodegradable foam plastic, which is discussed in photodegradable plastics, polyhydroxybutyrate (PHB) and polyhydroxy valerate (PHV). Its function is similar to that of PE and P P. The price of PE is about 10 times higher. The truth is that the ultraviolet radiation effect of polymer is weakened. The long chain fragments are divided into low molecular weight and decreased body function. In the air, fragments with lower molecular weight further oxidize and break free radical chains, further degrading into carbon dioxide and water.
According to the degradation mechanism, degradable plastics can be divided into photodegradable plastics, photosensitizer photodegradable plastics, biodegradable plastics and various degradable plastics composite multifunctional degradable plastics. According to the premise of degradable plastics, it can be divided into photodegradable plastics, biodegradable plastics, fully biodegradable plastics, partial biodegradable plastics, oxidative degradable plastics, water degradable plastics and composite degradable data composed of the above three degradable plastics.
Photodegradable plastics with photosensitizers are several photosensitizers in plastic processing. Due to the photoexcitation effect and photochemical reaction of photosensitizers, bubble bag materials can accelerate the photodegradation of polymers. This kind of plastics has the advantages of simple manufacturing method and low cost. As long as photodegradable plastics can be degraded in sunlight, they will be limited by geographical and weather conditions.
Bubble bag, also known as air cushion film, bead gum, foam roller, etc., is made of low density polyethylene. At that time, it was widely used as a bright and soft packaging material, which was widely used. The principle of the bubble bag is to make the gas film into bubbles, so as to avoid the impact of the product and ensure the maintenance effect of the product in vibration. At the same time, it has thermal insulation effect. It is suitable for packaging or turnover of products in different industries. Because the central layer of the bubble bag is full of air, the body is light and elastic, with sound insulation, shock and abrasion protection functions, but also with waterproof, moisture-proof, pressure resistance, drag reduction performance.
