Pet packing belt is a widely used plastic environmental protection packing belt. Pet packing belt has been produced in China for more than 20 years. Since 2002, China's demand for pet strapping has grown at an annual rate of 500%. It has been widely used in wood, paper, steel, aluminum ingot, steel pipe, profile, glass, building materials, ceramics, electrical appliances, metal products, tobacco, chemical fiber, cotton and other industries. Transparent appearance (opaque after adding tackifying agent), smooth surface or prismatic pattern. The main raw material of pet packing belt is polyethylene terephthalate.
PP packing belt is a kind of packing belt (strapping belt). It is made of polyethylene, polypropylene resin, cold rolled strip steel as the main raw materials, and nylon and polyester as the raw materials. It is made by extrusion unidirectional drawing and hot treatment. In addition to being used for sealing and bundling corrugated boxes, hot rolled steel coils and cold rolled steel coils, it can also be used for bundling glass, pipes, materials, fruits, etc.
Two different materials are used in packaging consumables, and have been popular in China for 20 years. The two kinds of packing belts have different characteristics, so they are applied in different industries. PET plastic steel belt is often used to pack heavy goods because of its tensile strength, low elongation, high temperature resistance, good safety and other characteristics, while PP packaging belt is often used to pack light goods because of its small specific gravity, low tensile strength and long meter per unit weight. Generally, electronic products are packed in cartons.
