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 undergo further oxidation in the air, resulting in free radical chain breakage and further degradation into CO2 and water.

Degradable plastics can be classified according to their degradation mechanism into photo degradable plastics, photo degradable plastics with added photosensitizers, biodegradable plastics, and multifunctional degradable plastics composed of multiple degradable plastics. According to the premise of degrading plastics, they can be divided into photo degradable plastics, biodegradable plastics, fully biodegradable plastics, locally biodegradable plastics, chemically degradable plastics, oxidatively degradable plastics, water degradable plastics, and composite degradation data composed of the three types of degradable plastics mentioned above. Photodegradable plastics with added photosensitizers involve a small amount of photosensitizers during the plastic processing. Due to the photoexcitation effect and photochemical reaction of photosensitizers, which occur from the radical excitation source, Dongguan packaging materials can accelerate the photodegradation process of polymers. This plastic manufacturing method is simple and cost-effective. Photodegradable plastics can only degrade under the condition of solar radiation, and their widespread use is inevitably limited by geographical and weather conditions. What are the characteristics of bubble bags? Bubble bags, also known as air cushion films, bead adhesives, bubble rolls, etc., are processed from low-density polyethylene and were widely used as a type of transparent flexible packaging material at that time. The principle of Dongguan packaging materials is to use a film containing air to form bubbles to prevent product impact, ensuring maintenance when the product is subjected to vibration. It also has insulation and heat insulation effects, suitable for packaging or turnover of different products in various industries. Bubble bags are lightweight, elastic, and have the functions of sound insulation, shock resistance, and wear resistance due to the central layer being filled with air. They are waterproof, moisture-proof, and pressure resistant.
