Abstract

The invention discloses a layered cover film easy to strip. The layered cover film comprises an upper film and a lower film; the lower film is provided with a plurality of breather holes; an easy-to-strip layer is arranged between the upper film and the lower film; the stripping force between the easy-to-strip layer and the upper film is larger than the stripping force between the easy-to-strip layer and the lower film; and when the upper film is separated from the lower film, the easy-to-strip layer adheres to the upper film. The cover film is layered, after the cover film is stripped, the lower film is fixed to a plastic container, and contents in the container are prevented from spilling.

Description

technical field [0001] The invention relates to the field of packaging cover films, in particular to a layered easy-to-remove cover film, which is applied to the sealing of various plastic containers such as trays, cups and bottles. Background technique [0002] At present, most of the existing cover films are separated from the plastic container when the product is used. For the packaging of fragrances, hygroscopic agents, aromatherapy, insect repellants, moth balls, etc., the packaging is required to have excellent barrier properties before use, and the contents will not leak out during use. Although the conventional cover film can achieve good barrier properties before use through the combination of materials, the contents are easy to be taken out and spilled after being uncovered, which poses a great potential safety hazard, especially in environments with infants and children. In view of the above problems, the patent of the present invention provides a layered easy-to...
