PROCESS SHEET AND ITS MANUFACTURING METHOD
Document Type and Number:
Japanese Patent JP2004202978
Kind Code:
A
Abstract:

To provide an inexpensive process sheet capable of being manufactured for a short time (high speed molding) while having sufficient adhesiveness without using an adhesive such as an anchor coating agent or the like, having high heat resistance and more enhanced in surface releasability, and its manufacturing method.

In the process sheet 14 obtained by forming a surface layer 15 on a substrate 13 through an adhesive layer 16 without using the anchor coating agent, the surface layer 15 contains a 3-10C α-olefin homopolymer or copolymer as a main component and the adhesive layer 16 comprises a resin material containing 100-10 mass % of an ethylene (co)polymer (A) satisfying specific necessary conditions and 0-90 mass % of an other polyolefinic resin (B).
