Abstract
PURPOSE: After gelation, polyethylene tubes or sheets are oriented at a more stretch ratio in the traverse direction to form novel film used as cap seals, shrinking labels due to its excellent monoaxial shrinking properties in the traverse direction.
CONSTITUTION: A polyethylene resin is extruded into tubes or sheets and solidified by cooling. The resulting tubes or sheets are irradiated with ionizing radiation to crosslink to a level that the gel fraction attains 30W75wt% on the weight basis of the polymer. Then the orientation is conducted at a stretch ratio of 2.5 or less in the longitudinal direction and 3 or more in the traverse direction and the film is further irradiated with ionizing radiation to produce said film shrinking monoaxially in the traverse direction
