Characterized by its low weight, high elasticity and elasticity. It has a high tear resistance and has good welding and shrinking properties. Both very good heat resistance and suitable for deep freezing. LDPE is physiologically harmless and suitable for the packaging and storage of food.
Made by mixing LDPE and HDPE, combining the properties of LDPE and HDPE. Softer than LDPE and stiffer than LDPE. More flexible than HDPE. High scratch resistance. Meets food handling guidelines. This material has many uses, most commonly as a packaging material.
Polypropylene has a higher stiffness, hardness and strength than polyethylene, but these are lower than other plastics such as polyamide. Due to its low surface energy, it is very difficult to glue and print. PP is odorless and skin-friendly, it is suitable for applications in the food sector and pharmacy, it is physiologically harmless.
Great tensile and tear strength. Due to the lowest flexibility and vapor permeability, mainly used in injection-molded film extrusion. Stiffer and crackling feel than with LDPE films. HDPE is not shrinkable. Is not used with us.
