multilayer film

Abstract

The invention is directed to a multi layer film to be used as a flexible packaging material for enclosing and containing one or more compressible products in a sealed condition. The 5 layer film according to the invention consists of I. a first layer comprising low density polyethylene, II. a second layer comprising high density polyethylene, III. a third layer comprising linear low density polyethylene, IV. a fourth layer comprising high density polyethylene and V. a fifth layer comprising linear low density polyethylene.

Description

technical field [0001] The present invention relates to a multilayer film useful as a flexible packaging material for encapsulating and containing one or more compressible products in a sealed state. The invention also relates to a package comprising a product in a compressed state, the package comprising a multilayer film according to the invention. Background technique [0002] Companies as well as consumers are increasingly concerned about the environmental and sustainability aspects of packaging (see, for example, Challenges to Packaging in a global world, Gunilla Jonson, Marcus Wallenberg Prize symposium, September 30, 2005 and Marsh, Food Packaging, Journal of Food Science , Vol.72, 3, 2007, pages 39-55). Using smaller amounts of raw materials, reducing costs and developing additional packaging functionality have become important goals of R&D. As far as packaging is concerned, there are many theoretical options for increasing sustainability, such as eg using thinner ...
