Plastic packaging bags<\/a><\/strong> have become a preferred tool for storing and transporting food due to their convenience and versatility. Plastic packaging bags, especially those designed specifically for food, can effectively isolate air, moisture, and microorganisms, thereby extending the shelf life of food and maintaining its freshness.<\/p>\n\n\n\n

In this article, Huiyang Packaging<\/a><\/strong> will share the characteristics of plastic packaging bag types and their sealing guidelines and applications.<\/p>\n\n\n\n

Classification of plastic packaging bags<\/strong><\/h2>\n\n\n\n

Plastic packaging bags can be divided into the following types according to material classification:<\/p>\n\n\n\n

– OPP (biaxially oriented polypropylene)<\/p>\n\n\n\n

– CPP (cast polypropylene)<\/p>\n\n\n\n

– PP (polypropylene)<\/p>\n\n\n\n

– PE (polyethylene)<\/p>\n\n\n\n

– PVA (polyvinyl alcohol)<\/p>\n\n\n\n

– EVA (ethylene-vinyl acetate copolymer)<\/p>\n\n\n\n

– Composite bags (composite of multiple layers of materials, such as PET\/PE, BOPP\/PE, etc.)<\/p>\n\n\n\n

– Co-extruded bags (multi-layer bags formed by co-extrusion of multiple plastics)<\/p>\n\n\n\n

Polyethylene (PE) and polypropylene (PP) are trendy materials in the food packaging industry, mainly due to their safety, heat resistance, and transparency. Here is a detailed explanation of these two materials and the application of polyethylene terephthalate (PET) in food packaging:<\/p>\n\n\n\n

\"Sealing<\/figure>\n\n\n\n

Polyethylene (PE)<\/strong><\/h3>\n\n\n\n

Polyethylene is a common thermoplastic that is divided into several types, including low-density polyethylene (LDPE), linear low-density polyethylene (LLDPE), and high-density polyethylene (HDPE). PE materials have the following characteristics:<\/p>\n\n\n\n
