Title:
STRETCH FILM FOR PACKAGING FOODSTUFFS
Document Type and Number:
Japanese Patent JP3434399
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain a non-vinyl chloride-type stretch film having good packaging workability and good packaging finish.
SOLUTION: A stretch film for packaging foodstuffs has at least one layer of a mixed resin layer containing the following (A) and (B) components and is such that its storage elastic modulus (E') is in a range of 5.0×108 to 5.0×109 dyn/cm2 and that its loss tangent (tanδ) is in a range of 0.2 to 0.8, each being measured by the dynamic viscoelasticity measurement at a frequency of 10Hz and at a temperature of 20°C. The (A) component is a copolymer of a vinylaromatic compound and a conjugated diene, or a hydrogenated derivative thereof, and the (B) component is a petroleum resin, a terpene resin, a cumarone- indene resin and a rosin resin, or a hydrogenated derivative thereof.
