Introduction of material properties of PET strappingIntroduction of material properties of PET strapping
Pet strapping has become an indispensable packaging consumable in many industries, but many users generally just know what is pet strapping, but they don't know what kind of properties and characteristics it has. Today, let Relevant people will introduce it to you.
PET (polyethylene terephthalate) is a linear thermoplastic polyester and is one of the most widely used industrial plastics on the market. The density is (1.3-1.4) g/cm3, the intrinsic viscosity (1V) is (0.62-1.20) ml/g, and the melting point is (245-265)°C.
Pet plastic has high gloss, transparency, good weather resistance, impact resistance, abrasion resistance, creep resistance and dimensional stability. It has stable chemical stability, and is resistant to weak acids and organic solvents. High heat resistance, can maintain good physical properties, which allows him to have a broader space for sales and utilization in the market.
Nowadays, as a polymer material, the packing tape on the market has typical rheological characteristics: when it is used as a strapping material, continuous stress will inevitably produce creep deformation, resulting in the loss of strapping stability, resulting in loose product packaging. There are many studies on the rheological properties of its main raw material polypropylene plastics, mainly focusing on the model, temperature, application, aging and so on.If you want to know more about it please do not hesitate to contact me.
