لفة بلاستيكية من البولي إيثيلين PET لحماية الوجه القابل للتصرف

Physical and mechanical properties of PET sheet for thermoforming PET is a milky white translucent or colorless transparent body.
Polyethylene PET Plastic Roll  is a medium barrier material. the transmission coefficient for carbon dioxide is 180. m3 ～ and 2 · small MPa, the water absorption rate is 0.6%, and the water absorption is large.
Compared with other materials, Polyethylene PET Plastic Roll has high tensile strength, comparable to aluminum foil, 9 times that of PE-HD, and 3 times that of PC and PA.
Good barrier properties, stable size, high transparency, high impact strength, no Poisonous and tasteless, easy to thermoform, PET sheet can be made into various shapes of complex thermoformed products.
The commonly used PET sheet is an amorphous PETP resin, with a characteristic dryness of 0.6 to 0.7 dl, and electricity. PET sheets can be produced by extrusion casting. Amorphous transparent sheet, also called APET sheet, extruded and quenched by T-type head, usually has a thickness of 0.2mm to 0.6 ~. APET sheet can be used as a variety of transparent thermoformed packaging products. The crystalline modified PET sheet (CPET) also has high temperature resistance (15O-200 ° C). Usually a thickness of 0.20 to 1.00 mm.CPET cast sheet can be used as a thermoformed product. Crystallized PET sheet (CPET) also has high temperature resistance (150-200 ° C). Usually the thickness is 0.20 ~ 1. ~, CPET cast sheet can be used as a thermoformed product.
The requirements of thermoforming on materials are as follows:
① good heating extensibility, high height-to-diameter ratio (ie, stretching ratio), and good extensibility;
② sufficient high tensile strength, impact strength, and needle resistance Porosity;
③ Products with compound requirements must have good heat-dried strength;
④ Good transparency and gloss, which are convenient for the sale of packaged goods;
⑤ Waste packaging is easy to handle; It should have non-toxic, odorless or low-odor requirements; for products with color printing requirements, corona treatment should be performed. See table for general physical and mechanical properties of PErr sheet suitable for thermoforming.
