IN-MOULD LABELLING

摘要

There is disclosed a method of manufacturing an in-mould labelled article, the method comprising the steps of: placing a label comprising a film having a core comprising polypropylene/polyethylene random copolymer as its principal polymeric constituent into a mould for injection moulding, thermoforming, or blow moulding; holding the label in position; injecting a polymeric melt into, or thermoforming or blowing a polymeric preform in said mould so as to bind with the label; and removing the article from the mould. A process of in-mould labelling using such a label is also disclosed.

1. A process for in-mould labelling of an article with a polymeric film, comprising:
forming a label on an article with a polymeric film, wherein the film comprises at least a core layer comprising a random copolymer of polypropylene and polyethylene, which film shrinks on the application of heat and exhibits a maximum shrink force during residual shrinkage immediately after the application of the heat of not more than 500 cN.
