Abstract
The utility model relates to the technical field of packaging materials, in particular to PET composite paper for a wine box, which comprises an outer PET film, an outer isolation layer, a supporting inner plate layer, an inner isolation layer and an inner PET film which are sequentially adhered from top to bottom, wherein the inner support plate layer is of a strip-shaped single parallel laying structure, the anti-breakdown capability of the composite paper is improved by arranging the inner support plate layer and two isolation layers on two sides of the inner support plate layer, meanwhile, the two isolation layers are of honeycomb structures, impact force can be effectively buffered, the purpose of isolating heat and preserving is achieved, and the PET film arranged on the outer side of the isolation layer can also ensure that the composite paper still has waterproofness after the inner PET film and the outer PET film are broken.
Description
Technical Field
The utility model relates to the technical field of packaging materials, in particular to PET (polyethylene terephthalate) composite paper for wine boxes.
Background
The wine box package can promote the aesthetic degree of wine, and then influence its sales volume, just generally adopts cavity corrugated paper package with the packing now, has the sexual valence relative altitude, recoverable characteristics, but this kind of packaging material waterproof nature is not enough, and because the wine box is in the way of moving transportation, receives external force damage easily or the wine box is rocked when the wine bottle striking inboard makes it impaired, causes the carton packing to leak, causes leaking more easily to influence the quality of wine, consequently a novel PET composite paper for the wine box is urgently needed.
Disclosure of Invention
The utility model aims to provide PET composite paper for wine boxes, which solves the problems in the prior art.
In order to achieve the above purpose, the present utility model provides the following technical solutions: a PET composite paper for wine boxes comprises an outer PET film, an outer isolation layer, a supporting inner plate layer, an inner isolation layer and an inner PET film which are sequentially adhered from top to bottom, wherein the supporting inner plate layer is of a strip-shaped single parallel laying structure.
Preferably, the TPU aluminized film is arranged on the outer PET film.
Preferably, the outer PET film thickness is greater than the inner PET film thickness.
Preferably, the outer isolation layer and the inner isolation layer are made of corrugated paper and are honeycomb-shaped.
Preferably, the material of the supporting inner plate layer is epoxy plastic.
Compared with the prior art, the utility model has the beneficial effects that:
through setting up and supporting the interior lamina to set up two isolation layers in supporting interior lamina both sides, improve the anti breakdown ability of compound paper, two isolation layers are cellular structure simultaneously, can effectively cushion impact, and play thermal insulation's purpose, set up the PET membrane in the isolation layer outside, also can ensure when inside and outside one deck PET membrane breaks after, compound paper still has waterproof nature.
Drawings
FIG. 1 is a schematic cross-sectional view of the present utility model.
In the figure: 1. TPU aluminizer; 2. an outer PET film; 21. an inner PET film; 3. an outer isolation layer; 31. an inner isolation layer; 4. supporting the inner ply.
Detailed Description
The technical solutions in the embodiments of the present utility model will be clearly and completely described below. Embodiments of the present utility model are intended to be within the scope of the present utility model as defined by the appended claims.
Referring to fig. 1, the present utility model provides a PET composite paper for wine boxes: including from last outer PET membrane 2, outer isolation layer 3, support interior sheet layer 4, interior isolation layer 31, interior PET membrane 21 of adhesion in proper order, interior PET membrane 21 is high printing opacity PET membrane generally, can conveniently observe whether interior isolation layer 31 infiltration, when appearing impaired, in time change the wrapping paper, support interior sheet layer 4 and lay the structure for the strip monomer is parallel, monomer length is general control at 5cm to 10cm, width control is 2cm to 3cm, thickness 5mm to 10mm, the monomer is closely arranged, can play the local anti striking ability of support, be equipped with TPU aluminizer 1 on the outer PET membrane 2 and reduce the infiltration of infrared ray, play thermal-insulated effect, possess waterproof nature simultaneously, outer PET membrane thickness is greater than interior PET membrane thickness, outer PET membrane 2 is thicker, because receive the damaged probability of external force bigger, interior PET membrane 21 is thin, reduce cost, outer isolation layer 3 and interior isolation layer 31 are corrugated paper material and are honeycomb, can effectively cushion the impact, and play the purpose of keeping apart heat preservation, support interior sheet layer 4 material is epoxy plastics, possess certain hardness, and low cost.
Although embodiments of the present utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
