El polipropileno es una resina termoplástica obtenida por polimerización del propileno, denominada PP. El polipropileno tiene buena resistencia al calor, y los productos pueden ser esterilizados a temperaturas superiores a 100 ° C, y no se deforman a 150 ° C bajo la condición de ninguna fuerza externa. La estabilidad química del polipropileno es muy buena, [...].

It is suitable for injection molding, extrusion blow molding, thermoforming and other processing methods. widely used. PP plastic characteristics Non-toxic, tasteless, low density, strength, stiffness, hardness and heat resistance are better than low pressure polyethylene, can be used […]
Seguir leyendo1. PVA coated high barrier plastic film PVA-coated high-barrier film is made by coating PVA with nano-inorganic substances on polyethylene film, then printing and compounding. On the premise of not greatly increasing the cost, the technical bottleneck of poor barrier performance of the three-layer polyethylene co-extruded packaging film is solved. PVA coated high-barrier milk film […]
