Abstract

The invention discloses a paper-plastic container and a production method thereof. The paper-plastic container consists of an inner film layer, a paper layer, a printed layer and an outer film layer, and is characterized in that: the outer film layer is an extinction biaxially-oriented polypropylene (BOPP) layer; the printed layer is arranged on the inner side of the outer film layer; and the inner film layer is a polyethylene (PE) or polypropylene (PP) layer. The paper-plastic container and the production method thereof have the characteristics of paper surface film-coating uniformity, high anti-permeability, good printing effects, printed pattern drop resistance and no secondary pollution.

Description

A kind of paper container and production method thereof

Technical field

The invention belongs to the disposable container technical field, especially relate to a kind of paper container and production method thereof.

Background technology

Present paper container all is to adopt between two-layer leaching membrane layer to accompany ply of paper, it is traditional pouring membrane process method, be that the softening back of plastics is drenched on paper, because paper surface is uneven, so drenching on paper, also can spare by became uneven in plastics, this has just formed on the surface of paper even has not had plastics, drench the paper container that membrane process is produced and adopt, just have self resistance oxygen ability, the problem of permeability resistance difference, in container, just have the smell of paper, under the situation of internal tank or external humidification, the softening container of paper will lose deflection, can't guarantee the quality of container; Existing paper container of while, its printing mostly are surface printing or paste non-drying glue, and its printing effect is relatively poor relatively, easily comes off, and aesthetics is poor, and easily other containers are caused secondary pollution in the transportation use; Though the process of carrying out overlay film on paper is arranged at present, existing overlay film layer is with leaching membrane layer, PE layer, the PP layer can't be in conjunction with forming sealing, and this has just caused and can't adopt coating technique to produce the paper container.

Summary of the invention

The objective of the invention is to improve the deficiency of prior art and provide that a kind of paper surface overlay film is even, anti-permeability good, printing effect is exquisite, printed patterns can not come off, can not produce the paper container and the production method thereof of secondary pollution.

The object of the present invention is achieved like this, and a kind of paper container is made up of theca interna, ply of paper, printed layers and theca externa, is characterized in that theca externa is a delustring BOPP layer, and printed layers is in the inboard of theca externa, and theca interna is PE or PP layer.

In order further to realize purpose of the present invention, can adopt following steps production by paper container of the present invention:

A, with press printing on the delustring BOPP film, printing ink is no benzene printing ink, mode of printing is to print in the intaglio plate;

B, print as the BOPP diaphragm of adventitia and paper and carry out compoundly as the PE of inner membrance or PP, compound is the paper compound adhesive with glue, the temperature of compounding machine is heated compounded three grades of 30-95 degree respectively;

C, the compound paper packaging material that finishes are sent into the speedization chamber, under 55-65 degree temperature speedization 40-60 hour;

D, cross cutting, mould cutting machine on the good paper packaging material of speedization is die-cut to the container sheet material;

E, container made with container made machine on the container sheet material, adopt the ultrasonic heat-sealing, make finished container;

F, sterilization wrap warehouse-in.

Compared with the prior art the present invention has following distinguishing feature and good effect: what the utility model adopted is that theca externa is the BOPP layer, guaranteed that like this covering of paper outside face mould evenly, theca interna is PE or PP layer, avoid existing pouring film to cover moulding inequality and caused the problem of self resistance oxygen ability, permeability resistance difference, printed layers is in the inboard of theca externa, the one, owing to be printed on theca externa, theca externa is the BOPP layer, determined its print surface smooth smooth, printing effect is good, and printed layers has been avoided the secondary pollution of printing-ink in interior survey; Theca externa is a delustring BOPP layer, and theca externa and theca interna are combined with each other, and forms the fully enclosed container; The paper container that adopts the inventive method to produce, exquisite appearance, the impermeabilisation oxidation resistance is strong, printing is printed combination process in adopting, not only pattern is exquisite clearly beautifully, wear-resisting bears dirty, does not come off, and printing ink makes people or thing not to contact with printing-ink between adventitia and paper, avoid the secondary pollution of chemical substance, improved safety.

Description of drawings

Below in conjunction with width of cloth figure and embodiment the present invention is described in further details.

Fig. 1 is a kind of structural representation of the present invention.

The specific embodiment

Embodiment, a kind of paper container, with reference to Fig. 1, be by theca interna 1, ply of paper 2, printed layers 3 and theca externa 4 are formed, and theca externa 4 is delustring BOPP layer, and printed layers 2 is in the inboard of theca externa 4, theca interna 1 is PE or PP layer, present embodiment adopts PE as theca interna 1, is that printing ink is no benzene printing ink with press printing on the delustring BOPP film, mode of printing is to print in the intaglio plate, BOPP diaphragm that prints and paper and PE carry out compound, and compound is the paper compound adhesive with glue, and the temperature of compounding machine is heated compounded three grades of 30-95 degree respectively, the compound paper packaging material that finishes is sent into the speedization chamber, under 55-65 degree temperature speedization 40-60 hour, mould cutting machine on the good paper packaging material of speedization was die-cut to the container sheet material, with container made machine on the container sheet material, finished container is made in the heat-sealing of employing ultrasonic, terminal disinfection packing warehouse-in.

Claims
