Which is high temperature resistant, pp packing belt or pet packing belt?

PET packaging belt is made of polyester (PET) material, commonly known as plastic steel belt. Therefore, polyethylene terephthalate is an important material and has been finely processed. It is a new environmental protection packaging material used to replace steel strip in the world. It has been widely used in nonferrous metals, steel industry, chemical fiber industry, aluminum ingot industry, paper industry, screw industry, tobacco industry, electronics industry, textile industry and wood industry, which can greatly reduce the packaging cost. ? The melting point of Shuanghui PET plastic steel strip is 255℃~260℃, and it can be permanently connected and stable between-10℃ ~120℃, with excellent dimensional stability. Due to the factors of materials and manufacturing technology, PET tape can cope with all kinds of weather changes and resist high temperature and high humidity.

PP packing tape, with polypropylene (PP) as the main raw material, is made of polypropylene drawing grade resin, which is tensile broken due to its good plasticity.

High strength, bending fatigue resistance, low density, good tensile impact performance and convenient use have been widely used in various fields. The melt degree of pp packing tape is generally 80 degrees Celsius.
