TH3747A - Multiple sheet structures How to make such a structure and a container made of it - Google Patents

Abstract

Multi-layer paperless structure with a structured sub-structure. Provided to make tube-shaped containers for medicine, paints and other products.The plate structure consists of a combination that Unique of the polymer layer Including a polymer layer that has been arranged in a single core (Polypropylene or high-density polyethylene) The sheet structure has two heat-sealed outer surfaces to form a tube-shaped container by sealing the overlay with a And the resulting container has improved strength and improved permanent folding properties. So there is a way to make a sheet structure with a structured sub-structure as well.

1. Method for making a multilayer paperless sheet structure consisting of a procedure (a) co-extrusion of three polymer layers forming a frame. Creating a film substrate of those three layers and making The films are arranged in a single axis with a rate of gradation. That is from about 2/1 to about 6/1, all three floors as Said to be a polyethylene layer The first adhesion layer and the polymer layer arranged in order (b) the priming of the polymer substrate arranged with a primer (c) the extrusion polyethylene layer.
