Heat shrinkable tubes and tapes made of irradiated polyethylene have b
een produced for several years. The memory effect of such products is
widely used in many industrial applications. Hot-melt adhesive is ofte
n applied to provide better sealing properties of heat shrinkable prod
ucts. Radiation grafting of hot-melt adhesives based on PP and copolym
ers like EVA was investigated. Several monomers were selected for radi
ation grafting process. Comparison of structural and mechanical proper
ties with nonirradiated material was carried out.
