Description

A kind of multilayer paper-plastic container

Technical field

It the utility model is related to Paper plastic die set technical field, a kind of multilayer paper-plastic container of specific design.

Background technology

Current paper-plastic container is all to accompany ply of paper using two layers of film interlayer, i.e., traditional film process, be by Plastics softening after leaching on paper, because paper surface is uneven, thus plastics leaching on paper also can became uneven it is even, this is with regard to shape , even without plastics, and use the paper-plastic container of film technique productions on the surface of paper, just with itself resistance oxygen ability, The problem of permeability resistance difference, the smell of paper is just had in container, in the case where container is either internally or externally moist, paper Softening container will lose deflection, can not ensure the quality of container, while existing paper-plastic container, and it is mostly surface printing that it, which prints, Or adhesive sticker is pasted, its printing effect is relatively poor, easy to fall off, and aesthetics is poor, and easily to other during transport use Container causes secondary pollution, although having the process that overlay film is carried out on paper, existing coating layer and film at present Layer, PE layers, PP layers can not combine to form sealing, and this has resulted in that coating technique production paper-plastic container can not be used, in order to solve Above-mentioned technical problem, present applicant has invented a kind of paper-plastic container, and has applied for patent（Authorization Notice No. is CN202029499U）, but applicant has found that the technology also has the defects of certain, produced in enormous quantities by actual use When production efficiency reduce, and produce paper sheet break phenomenon it is serious, production cost is higher, is unfavorable for producing in enormous quantities.

The content of the invention

Based on above-mentioned technical problem, the utility model provides a kind of follow-on multilayer paper-plastic container, to adapt to factory Production in enormous quantities, the yield rate of paper is improved while guaranteed efficiency.

To achieve these goals, the technical solution adopted in the utility model is a kind of multilayer paper-plastic container, by inner membrance Layer, intermediate layer and theca externa are arranged in order composition, and the theca interna is PE or PP layers, and the intermediate layer is duplex paper, and institute State and be provided with pet layer among double-deck ply of paper, the theca externa is CPP layers.

Preferably, the intermediate layer is made up of another kind as the technical program PET aluminium coateds and single-part stationery two parts, institute State PET aluminium coateds to contact with theca externa, the single-part stationery contacts with theca interna.

Preferably, the intermediate layer is single-part stationery to another kind as the technical program.

Wherein, the theca externa can also be BOPP layers.

Preferably, the theca externa is by CPP layers, aluminium platinum layer and BOPP layer three parts groups for another kind as the technical program Into, wherein, aluminium platinum layer is provided with the outside of the CPP layers, BOPP layers are provided with the outside of the aluminium platinum layer.

Compared with prior art, the good effect that the utility model obtains is as follows：The utility model is using intermediate layer For duplex paper, and pet layer is provided among the duplex paper, due to the addition of the aluminium coated or aluminium platinum layer of pet layer, both ensured Paper outer surface covers that modeling is uniform, and theca interna be PE or PP layers, and avoiding existing film, to cover modeling uneven and cause itself resistance The problem of oxygen ability, permeability resistance difference, the hardness and pliability of paper are in turn ensure that, paper quality greatly improves, and is not easy Broken, yield rate significantly rises；Theca externa is CPP layers, theca externa can be made to meet with theca interna together with, formed closed Container；The utility model paper-plastic container, exquisite appearance, impermeabilisation oxidation resistance is strong, and printing uses inner print combination process, not only Pattern fineness is clearly beautiful, wear-resisting to be born dirty, not to fall off, and is designed to double-deck paper structure, and PET is provided among duplex paper Layer, improves paper quality, non-breakable, is adapted to workshop etc. to produce in enormous quantities, yield rate is higher, cost-effective.
