MULTILAYERED FILM, MULTILAYERED SHEET AND EASILY OPENABLE PACKAGING CONTAINER

摘要

PROBLEM TO BE SOLVED: To provide a multilayered sheet and a multilayered sheet both of which are reduced in the irregularity of seal strength, easy to recycle to be useful as environment corresponding type ones and suitable as an easily openable packaging container, and the easily openable packaging container using the multilayered sheet. SOLUTION: The multilayered film consists of (A) a propylene resin layer, (B) an adhesive resin layer having adhesiveness with respect to an ethylenic resin, (C) an olefinic resin layer containing an ethylenic resin and (D) an ethylenic resin layer having adhesiveness with respect to a styrenic resin. The multilayered sheet consists of the layers (A)-(D) and a styrenic resin layer (E). The interlaminar strength of the (A)-layer and the (B)-layer is 2-20 N/15 mm in the multilayered film and the multilayered sheet. The easily openable packaging container is obtained by thermoforming the multilayered sheet.
