PE Bag Products

HDPE is a high density polyethylene material obtained from petroleum. The name comes from the abbreviation “High Density Poly Ethylene”, which stands for English equivalence. This name is generally used in industry and manufacturing sector.

HDPE is similar in appearance to LDPE, but much harder, with a molecular mass of around 150000-400000. Resistance to chemicals is good. Light and weather conditions are not as strong as in LDPE. This resistance can be increased with special fillings. Mechanical properties are very good, especially impact and tensile strength are high. Some fillers also improve the properties. Normally the tensile strength is around 225-350 kgf / cm2. Its temperature resistance is over 100 ° C.

It is a material suitable for many forming methods such as injection molding, extrusion powder coating, film drawing, rotary molding. Keeping the injection mold temperature at 50-70 ° C increases the product quality. HDPE is also very convenient for electrical applications. The market is also known as the rusty bag.
