RADIATION WORKING SHEET WITH SEALABILITY BY HIGH- FREQUENCY FUSION BONDING

摘要

PROBLEM TO BE SOLVED: To provide a radiation working sheet to be replaced with a polyvinyl chloride sheet and having excellent sealability and film strength by high-frequency fusion bonding by volume reducing via incinerating from a view point of a radioactive waste reduction. SOLUTION: The radiation working sheet comprises 20 to 28% of a vinyl acetate content, and an ethylene vinyl acetate copolymer sheet having a melt index of 7.5g/10 min or less. The sheet has high-frequency fusion bondability, tensile strength and radiation resistance equivalent to those of the polyvinyl chloride sheet. Even if it is incinerated, no chlorine gas is generated, and hence it can be incinerated after using, and a volume of its radioactive waste can be reduced.
