Laminated film of polyolefin resin

摘要

A laminated polyolefin resin film having an inner layer which contains 88 to 70 wt. % of a polyolefin resin and 12 to 30 wt. % of a double hydroxide having a peak temperature for liberating water of crystallization in a range between 160 DEG C and 300 DEG C and containing at least 5 wt. % of water of crystallization, and outer layers of a polyolefin resin which are laminated on respective surfaces of the inner layer, in which the content of the double hydroxide is from 8 to 25 wt. % based on the weight of the whole laminate film, which is excellent in high frequency heat sealability and useful as an agricultural film.
