In the interaction between modern business and daily life, plastic bags are everywhere, and according to the difference in materials, they are unique and have unique properties and uses.

Polyethylene (PE) packaging bags can be called the "evergreen tree" in the packaging industry. Low density polyethylene (LDPE) made of plastic bags soft texture, transparency, excellent tensile properties, commonly seen in the field of food preservation, like the supermarket wrapped in vegetables and fruits, thin food bags are mostly such, it can effectively isolate the outside water vapor and dust, extend the freshness of ingredients. High-density polyethylene (HDPE) is tough, crisp and wear-resistant, and is mostly made as shopping bags and garbage bags, which are not easily damaged by high strength to carry heavy objects, withstand daily friction and pulling, and play a key role in garbage collection and daily purchasing scenes.

Polypropylene (PP) packaging bags are known for high temperature resistance and strong chemical stability. The bags made of unstretched polypropylene (CPP) have high transparency and good flatness, which are suitable for packaging of exquisite food and stationery, clearly showing the appearance of products and improving the display effect of goods; Biaxial polypropylene (BOPP) film bag, the strength is higher, often used as snacks, daily necessities packaging, moisture-proof, oxygen resistance ability is excellent, can protect the quality of products in complex storage and transportation environment.

Polyvinyl chloride (PVC) material packaging bag plasticity is strong, can be adjusted by additives hardness, color and so on. Transparent PVC bags are widely used in clothing and jewelry packaging, allowing consumers to intuitively see product details and add visual appeal; However, in view of its chlorine content, the environmental protection and safety control are more strict when used, especially in food contact applications.

Polyester (PET) material packaging bags show high transparency and high strength characteristics, which are common in high-end food and electronic accessories packaging. Like tea, coffee and other products with high preservation requirements, PET packaging bags have good gas barrier and temperature resistance to prevent aroma loss and quality deterioration; Electronic products with its packaging, can prevent scratching, static electricity, to ensure that precision parts intact.

Different plastic bags perform their roles, and at the same time, they are also deepening with the concept of environmental protection, towards the road of degradable and green innovation, and continue to meet the needs of the development of The Times.
