Abstract

The utility model relates to a paper plastic cover mainly for a food container. The paper plastic cover is conical, cylindrical or of other vessel shapes and formed by compounding an inner layer and an outer layer; the outer layer is a plastic film; the inner layer is a food packing paper; and graph-text is printed on the plastic film. The plastic film of the paper plastic cover adopts a vacuum aluminizing biax orientation polyester film or a vacuum aluminizing biax orientation polypropylene film, a pearlescent film or a PP synthetic paper. The paper plastic cover has small pollution, meets the requirement for environmental protection, and greatly strengthens the fastness, stiffness and the molding effect.

Description

The paper cover

Technical field:

The utility model relates to a kind of paper cover that food holds utensil that is mainly used in.

Background technology:

At present domestic generally adopting material is art paper in the production of ice cream cone paper cover, in order to reach the aesthetic of paper cover, generally all is to adopt the mode of offset printing to print cross cutting then, the reel moulding.But there are several like this shortcomings at present in this mode:

1, the paper of Cai Yonging is an art paper, and art paper contains fluorescent material and french talc, is not suitable for packaging for foodstuff.

2, offset printing process is that art paper is subjected to influencing paper cover surface and the paper pulp obscission can occurring of steam in egg tube storage process with material, has promptly influenced the food that polluted again attractive in appearance.

3, printing ink has the characteristic of animal migration, certainly will pollute inherent food.

4, after the offset ink drying fission reaction can take place, give out a pungent smell, this fission reaction certainly will have influence on the mouthfeel of food, thereby has influence on quality, the safety of product, does not meet environmental demands.

The utility model content:

Technical problem to be solved in the utility model is to overcome existing above-mentioned deficiency in the prior art, and a kind of paper cover little, effective, that intensity is high that pollutes is provided.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: this paper cover, it is characterized in that the paper cover is all the other direction osed top container shapes of an opening and two-layerly compoundly is made of inside and outside, its skin is a plastic film, its internal layer is a used for packing foods paper, is printed with picture and text on the plastic film.

Plastic film described in the utility model adopts vacuum aluminum-coated biaxial tension mylar or vacuum aluminum-coated biaxial tension polypropylene film or pearly-lustre film or PP synthetic paper.

Paper cover described in the utility model is taper shape or cylindrical shape.

It is little to the utlity model has pollution, compliance with environmental protection requirements, and fastness, deflection and the molding effect of paper cover strengthen greatly.

Description of drawings:

Fig. 1 is the structural representation of the utility model embodiment 1.

Fig. 2 is the A-A cutaway view of Fig. 1.

The specific embodiment:

Referring to Fig. 1～Fig. 2, the utility model embodiment paper cover 1 is all the other direction osed top container shapes of an opening and two-layerly compoundly is made of inside and outside, its skin is a plastic film 2, its internal layer is a used for packing foods paper 3, be printed with picture and text with used for packing foods paper 3 compound places on the plastic film 2, figure that produces like this or literal are clear environmental protection again.

The key step that the utility model paper overlaps 1 production method is:

Vacuum aluminum-coated biaxially oriented polyester film (is VmPET, the VmPET vacuum available bidirectional stretching polypropylene film of aluminizing is that BOPP, pearly-lustre film replace) to print in (general environment temperature at 15～30 degrees centigrade, humidity about 60～70%) usually down with environment-friendly type aqueous China ink (for example Shanghai Toyo Ink, Shanghai Chinese redbud printing ink etc.), environment-friendly type aqueous black main purpose is to guarantee safe and sanitary;

Vacuum aluminum-coated biaxially oriented polyester film that prints and used for packing foods paper carry out compound with the speed of 120 meters～180 meters of per minutes with high speed and dry compounding machine (middle illawarra mountain pine moral, the production of Jiangyin Correspondent be representative) with water soluble adhesive (for example water soluble adhesive of manufacturer production such as American-European chemistry in Huzhou and Mitsui Wu Tian), perhaps adopt and drench the film machine in the compound mode of extruded type, compound under the speed of 120 meters～200 meters of per minutes;

In drying room, toasted 16 hours under the situation of 48 degree celsius temperature and normal atmosphere (An), use electrically heated form, the hot air circulation of going forward side by side to keep air-flow unimpeded in the drying room, keep humidity below 40%;

Cross cutting, product section promptly of the prior art;

The reel moulding, this step is same as the prior art.

The utility model embodiment final products are conical or the egg coil paper of cylindrical or other container shapes is moulded cover, and its structure adopts VmPET/ used for packing foods paper usually: VmPET thickness is 12 μ m-25 μ m generally speaking, and the grammes per square metre of used for packing foods paper is 70g/m ²-180g/m ²

Main feature of the present utility model comprises:

It is to guarantee safe and sanitary that the utility model adopts the main purpose of environment-friendly type aqueous China ink, because offset printing is directly on paper Printing, what use during offset printing is resin printing ink, shifts easily or pollution.

Being completed for printing rear VmPET and packaging for foodstuff paper using, to carry out compound, used composite glue be that water soluble glue has been guaranteed product The product safe and sanitary has improved the deflection of product, plays simultaneously the effect of waterproof.

Two-layerly be placed in the drying room in 48 degrees centigrade situation baking after compound 16 hours, this step guarantee the product free from extraneous odour and The bacterium index can be up to state standards. Because this procedure offset printing do not have, therefore may cause on the paper-plastic sleeve bacterium colony index not Up to standard.

The advantage of egg tube paper-plastic sleeve comprises:

A) product employing plastic sheeting and packaging for foodstuff paper using are compound, and water preventing ability improves greatly and the packaging for foodstuff paper using does not contain fluorescent material With talcum powder.

B) plastic sheeting has improved product specification through being compounded with a kind of metal-like with used for packing foods paper after vacuum aluminum-coated.

C) printing-ink has adopted environment-friendly type aqueous China ink, has avoided the pollution of food and the pollution of environment.

D) fastness, deflection and the molding effect of paper cover strengthen greatly.

The simple deformation or the combination of every the utility model embodiment technical scheme and technical characterictic all should be thought to fall into protection domain of the present utility model.
