Laminate with a styrenic polymer layer
First Claim
1. A laminate which comprises (a) a layer of (i) a styrenic polymer having at least 30% racemic pentad and a crystallinity of at least 25% or (ii) a composition consisting essentially of said styrenic polymer and at least one additive selected from the group consisting of inorganic fine particles, antioxidants, antistatic agents, flame retardants, and other resins than said styrenic polymer, said layer having a thickness of 5 to 50 μ
- m and (b) a layer of natural paper.

Abstract
There is disclosed a laminate comprising (a) a layer of a styrenic polymer having a higher degree of syndiotactic configuration and a crystallinity of at least 25%, preferably 35%, (b) a layer of paper and optionally (c) an adhesive layer and (d) a barrier layer. The above laminate is excellent in heat resistance, hydrolytic resistance, tearability, dead foldability and gloss and can find a wide range of effective application.
