High Density Poly Ethylene (HDPE) has excellent tear strength, good moisture barrier properties and high rigidity. HDPE bags are Suitable for use in supermarkets, shops, homes etc. and available in thickness from 8um – 40um. Low Density Poly Ethylene (LDPE) Bags is comparatively lower in density and has less hardness, stiffness and strength compared to HDPE, but better ductility.
