Problems solved by technology

Chili sauce has the characteristics of sour, spicy and salty. In the traditional process of packaging acid and alkaline products, PET / dry compound / PE structure is usually used, that is, the PET film and PE film are glued together through the glue layer. This structure is easy to appear. The contents of the packaging erode the glue layer, resulting in stratification of the glue layer, which affects the packaging and shelf life of the contents

Abstract

The invention specifically relates to a chilli sauce packaging composite film and a preparation method thereof. The packaging composite film is formed by tightly attaching a PET printing thin film layer which is 12 microns thick, a functional polyethylene thin film layer which is 15-20 microns thick and a PE thin film layer which is 60-80 microns thick, wherein the PET printing thin film layer, the functional polyethylene thin film layer and the PE thin film layer are connected in sequence; the functional polyethylene thin film layer is of a double-layer co-extrusion composite structure, and one side, which is adhered to the PET printing thin film layer, of the functional polyethylene thin film layer is provided with an ethylene acrylic acid copolymer layer; one side, which is adhered to the PE thin film layer, of the functional polyethylene thin film layer is provided with a low-density polyethylene and white master batch blending layer; the weight ratio of low-density polyethylene to white master batches is 20 to 3; the thickness ratio of the ethylene acrylic acid copolymer layer to the low-density polyethylene and white master batch blending layer is 2 to 3. The composite film has high performance such as high sealing intensity, low cost, good sealing effect, high sealing flatness and high pollution resistance and also has the advantages of good anti-medium effect, low cost, difficulty in layering and the like.

Description

Technical field [0001] The invention belongs to the technical field of packaging materials, and specifically relates to a chili sauce packaging composite film and a preparation method thereof. Background technique [0002] With the acceleration of the pace of life, the composite film small packaging of chili sauce has been favored by people for its many advantages such as easy portability, beautiful appearance and quick use. Chili sauce has the characteristics of sour, spicy and salty. In the traditional process, when packaging acid-alkaline products, the PET / dry compound / PE structure is usually used, that is, the PET film and the PE film are glued together through a glue layer. This structure is easy to occur. The packaging contents erode the glue layer, causing the glue layer to stratify, thus affecting the packaging and shelf life of the contents. Contents of the invention [0003] One of the objects of the present invention is to provide a packaging composite film for...
