Abstract

The utility model discloses a high resistant separates antiseep curtain coating polypropylene film, including sandwich layer, heat-seal layer and corona layer, the sandwich layer sets up between heat-seal layer and corona layer, and heat-seal layer surface adheres to high barrier layer, and high barrier layer surface presents the crest-shaped arch of evenly arranging through the impression. The utility model has the advantages of reasonable design, through making high barrier layer surface present mountain peak-like arch, reduce its area by the fish tail, removed the use on sclerosis layer from, reduce the thickness of film.

Description

High-barrier leakage-proof cast polypropylene film

Technical Field

The utility model relates to a high resistant separates antiseep curtain coating polypropylene film.

Background

The cast polypropylene film is widely applied to various packaging fields due to the advantages of high transparency, good flatness, uniform transverse and longitudinal properties and the like, but the barrier property and the anti-seepage property are not good, in order to ensure that the cast polypropylene film has good barrier property, a high barrier layer is generally attached to the surface of the cast polypropylene film, the high barrier layer is generally a vinylidene chloride-acrylate copolymer biaxial oriented film, the cast polypropylene film is not wear-resistant, in order to avoid the abrasion of the high barrier layer, a hardened layer is attached to the surface of the cast polypropylene film, but the hardened layer can increase the thickness of the cast polypropylene film, and the performance of the cast polypropylene film is reduced.

SUMMERY OF THE UTILITY MODEL

The utility model relates to a high resistant separates antiseep curtain coating polypropylene film for solve above-mentioned problem.

To achieve the purpose, the utility model adopts the structure that: the utility model provides a high resistant separates antiseep curtain coating polypropylene film, includes sandwich layer, heat-seal layer and corona layer, and the sandwich layer setting is between heat-seal layer and corona layer, and heat-seal layer surface adheres to high barrier layer, and high barrier layer surface presents the crest-like arch of evenly arranging through the impression, the most advanced of crest-like arch is planar structure, and the spraying has the nanometer silica powder on the planar structure.

The beneficial effects are as follows: the utility model has the advantages of reasonable design, through making high barrier layer surface present mountain peak-like arch, reduce its area by the fish tail, removed the use on sclerosis layer from, reduce the thickness of film.

Drawings

The invention will now be described, by way of example, with reference to the accompanying drawings, in which:

fig. 1 is a schematic structural diagram of the present invention.

Detailed Description

All of the features disclosed in this specification, or all of the steps in any method or process so disclosed, may be combined in any combination, except combinations of features and/or steps that are mutually exclusive.

Any feature disclosed in this specification (including any accompanying claims, abstract and drawings), may be replaced by alternative features serving equivalent or similar purposes, unless expressly stated otherwise. That is, unless expressly stated otherwise, each feature is only an example of a generic series of equivalent or similar features.

The high-barrier anti-leakage cast polypropylene film comprises a core layer 1, a heat-sealing layer 2 and a corona layer 3, wherein the core layer 1 is arranged between the heat-sealing layer 2 and the corona layer 3, a high-barrier layer 4 is attached to the surface of the heat-sealing layer 2, the surface of the high-barrier layer 4 presents mountain peak-shaped bulges which are uniformly distributed through imprinting, the tips of the mountain peak-shaped bulges are of a planar structure, and nano silicon dioxide powder is sprayed on the planar structure.

The utility model has the advantages of reasonable design, through making high barrier layer surface present mountain peak-like arch, reduce its area by the fish tail, removed the use on sclerosis layer from, reduce the thickness of film.

The present invention is not limited to the foregoing embodiments. The invention extends to any novel feature or any novel combination of features disclosed in this specification, and to any novel method or process steps or any novel combination of features disclosed.
