LDPE (Low-Density-Polyethylen) or soft polyethylene is soft and especially adaptable It is heat resistant up to a maximum of +60°C and cold resistant down to -50°C. HDPE (High Density Polyethylen) oder hard polyethylene has a higher density and is stronger than soft polyethylene. It is heat resistant up to a maximum of +90°C and cold resistant down to -50°C.
HDK is a combination of the specific material characteristics of LDPE and HDPE. The Result: Good high density characteristics and extremely tear-proof
