Abstract
The utility model discloses a breathable composite polyethylene film, which comprises a base material, wherein the base material is provided with a double layer, a plurality of plastic ribs are clamped between the two layers of base material at intervals, and the plastic ribs are arranged into a corrugated structure; the utility model has reasonable structural design and convenient use, on one hand, the integral tensile strength of the polyethylene film can be improved, and on the other hand, the polyethylene film can have good air permeability.
Description
Technical Field
The utility model relates to the field of polyethylene films, in particular to a breathable composite polyethylene film.
Background
The PE film is produced by PE particles, has moisture resistance and small moisture permeability, and can be used for producing products with different properties such as low-density, medium-density and high-density polyethylene, crosslinked polyethylene and the like according to different manufacturing methods and control means.
In order to make the polyethylene film breathable, a plurality of ventilation holes are usually formed in the polyethylene film at intervals so as to make the polyethylene film breathable, but the tensile strength of the polyethylene film is easily reduced due to the mode, and the ventilation holes are simply formed in the polyethylene film at intervals so that the polyethylene film is poor in breathability, so that improvement is still needed.
Disclosure of Invention
The utility model aims to solve the problems, and provides a breathable composite polyethylene film which comprises a base material, wherein the base material is provided with a double layer, a plurality of plastic ribs are clamped between the two layers of base material at intervals, the plastic ribs are arranged into a corrugated structure, and a plurality of ventilation holes are formed in the plastic ribs at intervals.
Preferably, the plastic ribs are hollow structures, and the plastic ribs are made of high-density polyethylene.
Preferably, the air holes penetrate through the upper layer of base material and the lower layer of base material.
The beneficial effects of the utility model are as follows: the utility model has reasonable structural design and convenient use, on one hand, the integral tensile strength of the polyethylene film can be improved, and on the other hand, the polyethylene film can have good air permeability.
Drawings
The utility model will now be described by way of example and with reference to the accompanying drawings in which:
FIG. 1 is a schematic view of the overall structure of the present utility model;
FIG. 2 is a schematic side elevational view of the present utility model;
FIG. 3 is a schematic view of the partial structure of FIG. 1 in accordance with the present utility model;
in the figure: 1. a substrate; 2. plastic ribs; 3. and (5) ventilation holes.
Description of the embodiments
All of the features disclosed in this specification, or all of the steps in a method or process disclosed, may be combined in any combination, except for mutually exclusive features and/or steps.
Any feature of the present description may be replaced by alternative features serving the same or similar purpose, unless expressly stated otherwise. That is, each feature is one example only of a generic series of equivalent or similar features, unless expressly stated otherwise.
The breathable composite polyethylene film shown in figures 1, 2 and 3 comprises a base material 1, wherein the base material 1 is provided with a double layer, a plurality of plastic ribs 2 are clamped between the two layers of base material 1 at intervals, the plastic ribs 2 are arranged into a corrugated structure, and a plurality of ventilation holes 3 are formed in the plastic ribs 2 at intervals.
The plastic ribs 2 are of hollow structures, and the plastic ribs 2 are made of high-density polyethylene.
The air holes 3 penetrate through the upper layer of base material 1 and the lower layer of base material 1.
In the use process, the plastic ribs 2 are of hollow structures and are matched with the ventilation holes 3, so that the film can be ventilated in multiple directions, and the ventilation property of the film is improved; the plastic ribs 2 can improve the overall tensile strength of the film; the plastic ribs 2 are arranged into a corrugated structure, so that the overall tensile strength of the film can be further improved.
The beneficial effects of the utility model are as follows: the utility model has reasonable structural design and convenient use, on one hand, the integral tensile strength of the polyethylene film can be improved, and on the other hand, the polyethylene film can have good air permeability.
The utility model is not limited to the specific embodiments described above. The utility model extends to any novel one, or any novel combination, of the features disclosed in this specification, as well as to any novel one, or any novel combination, of the steps of the method or process disclosed.
