LDPE (low density polyethylene) is the oldest type of polyethylen, which is used for plastic bags, packagings. LDPE has good transparency and seal ability. LDPE material loooks glossy, good for photoprinted bags and films. It´s common used for patch handle bags, soft loop bags and die cut bags. In North Europe LDPE is still used for T-shirt bags. We can extrude LDPE films with thickness between 18-180micr.
HDPE (high density polyethylen) is stronger than LDPE on stretching, but it tears easily. This material is highly suitable for T-shirt bags and die cut handle bags. The thick HDPE (50-100micr.) is often used for luxury bags. Naturally HDPE is lustreless and mat. The prices of HDPE and LDPE are very often changed on the market. We can extrude HDPE films with thickness between 8-100micr.
MDPE (medium density polyethylen) is newest consist of polyethylen. It looks like LDPE and HDPE is mixed. We can extrude MDPE films with thickness between 8-100micr.
