Introduction of strapping and characteristics of PET plastic strappingIntroduction of strapping and characteristics of PET plastic strapping
Sling is a mixture of two types made of PP and PET plastic.
The main production process: plastic granules hot melt-pinch-molding-cooling--winding-packaging-storage
Polypropylene packaging tape is heated, melted, stretched and cooled to produce a mesh structure of packaging materials, which affects the tension of the packaging with tension, length, bending, extension, etc. and other parameters are the same, the longer the lower the cost The quality of basic parameters.
Poor elasticity, easy corrosion, and lack of higher prices, the international community is increasingly replacing steel strapping PET strapping straps. At present, domestic papermaking, steel, chemical fiber, cotton, glass, construction materials, aluminum, tobacco, electronics, printing, ceramics, wood, flooring, metal cans, electrical circuits and electrical products and other industries, as well as in transport packaging pallet weight strapping, etc. , To gradually promote and expand applications, has a good market prospects.
The advantages of PET strap: (1) High strength and good flexibility: PET plastic steel belt, and plastic belt, but it has the strength of tough steel and PP in one, to overcome the sufficient strength or fragility of traditional packaging materials, And other disadvantages. 5%, long-term tightening force, not back loose, hanging strong physical shock cushion and 5% elongation. The tensile strength of the PP rope is twice, but it is a small change in expansion. Only the sixth polypropylene maintains the tension, and the swollen volume easily relaxes after a long period of physical packaging.
(2) Safety: PET plastic steel belt has no sharp edges, will not scratch the packaging, will not hurt your hands, cut, no special tools, even if it is tied tightly, the cut will not hurt.
(3) Adaptation: Because the polymer material used has excellent weather resistance, it can be melted at 260°C to maintain good dimensional stability from -50°C to 100°C. Not only is it resistant to high temperature and humidity, but it does not like the tensile strength and moisture loss of rusted steel, and the strong damping force.
(4) Environmental protection: PET is widely used in food, textile industry, environmental protection materials, can be recycled. The information of long-term exposure of PET strapping does not like the absorption of moisture and rust in the air as a result, to prevent the hidden danger of rusted steel belt and contamination by the packaging
(5) Economy: The length of one ton of steel is equal to 6 tonsIf you want to know more about it please do not hesitate to contact me. WhatsApp:+86-15966835076.
