Preparation of polyethylene films |
摘要 |
A very low density polyethylene (VLDPE) film is disclosed. The film has a high average heat seal strength and physical strength. The VLDPE has a density within the range of about 0.880 to 0.914 g/cm<SUP>3</SUP>. The film has a seal initiation temperature lower than or equal to 95° C. and an average heat seal strength greater than or equal to 1.75 lb/in. The film has a machine-direction (MD) modulus greater than or equal to 12,000 psi. The film can be used as a monolayer film or as a layer of a multilayer film. It is suitable for heat sealable bags and many other applications.
