Abstract

PURPOSE: The title film usable for packaging perishable foods, etc., having improved softness, elasticity, transparency, and anti-fogging properties, consisting of a crosslinked ethylene-vinyl acetate copolymer having specific properties.
CONSTITUTION: A film consisting of a crosslinked ethylene-vinyl acetate copolymer with a vinyl acetate content of 5W20 wt%, having a gel fraction to express the degree of crosslinking of 20W45%, a compression restoration ≤ 10 sec, and an initial modulus of 5W20 kg/mm2. The film can be prepared by drawing the copolymer at 80W200°C and an area draw ratio ≥ 4.0.2W15 wt % of an anti-fogging agent is added, if necessary, to improve the properties. The compression reversion is a value for determining if the top film under a load returns to the original state easily.
EFFECT: Improved tensile strength and cold resistance.
