EASILY OPENABLE SEALED PACKAGE CONTAINER

摘要

When a container main body equipped with a flange and a lid member are heat-sealed, one of their heat-seal surfaces is composed of a coating film of a composition prepared by dispersing a small amount of an acid modified olefin type resin in a heat-curable resin and the other is composed of an olefin type resin and heat-sealing is applied between them. In this manner, the present invention provides a sealed container which can be opened easily along the heat-seal surface by a hand and which has high heat resistance and pressure resistance at the heat-seal portion.
