A kind of inelastic plastic packaging film
Technical field
The utility model belongs to the packaging film technical field, particularly a kind of inelastic plastic packaging film.
Background technology
At present, the kink of candy class and leisure food packing is generally used plastic sheeting (polyvinylchloride, polyethylene terephthalate) or paraffin paper.Plastic sheeting (polyvinylchloride, polyethylene terephthalate) has that printing effect is good, the adaptable advantage of automatic packaging, but do not meet the packaging for foodstuff hygienic requirements, also need during use to isolate, and environment is caused gross pollution because of being difficult to the degraded meeting with lining paper.Though the influence of paraffin paper environmental pollution is little, and also meet the packaging for foodstuff hygienic requirements,, have the shortcoming of printing effect difference and tensile strength difference still owing to the particularity of paper, when being used for packing automatically for every index request of paraffin paper than higher, otherwise easily produce directly influence production of fracture.Do you how to overcome plastic sheeting (polyvinylchloride, polyethylene terephthalate) and the existing shortcoming of paraffin paper? this problem still has to be solved.
The utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provide a kind of and meet the packaging for foodstuff hygienic requirements, can reduce environmental pollution, and printing effect is good, the adaptable inelastic plastic packaging film of automatic packaging.
For achieving the above object, the technical solution of the utility model has provided a kind of inelastic plastic packaging film, this plastic packaging film comprises that upper surface is provided with the thin layer and the ply of paper of printed layers, it is characterized in that, be provided with adhesive layer, ply of paper, paraffin layer and transparent polyethylene layer successively at described thin layer lower surface.
In the utility model, described thin layer is plastic sheeting or metallized film, and its thickness is 5 μ m~20 μ m.
In the utility model, the thickness of described ply of paper is 15 μ m~45 μ m.
The beneficial effects of the utility model are:
1, paraffin layer direct contact food meets the packaging for foodstuff hygienic requirements.
2, the non-degradable thing has dropped to 30% by 100% of original use plastic sheeting, has reduced the pollution to environment.
3, the printing effect of plastic sheeting or metallized film is good, has solved the problem of stencilling weak effect.
Required lining paper when 4, having cancelled plastic film packaging greatly reduces productive costs.
5, tensile strength is good, kink does not rebound, the automatic packaging comformability is strong, is applicable to the automated machine packing.
Description of drawings
Fig. 1 is the sectional structure scheme drawing of the inelastic plastic packaging film of the utility model.
Among the figure: 1, thin layer; 2, printed layers; 3, adhesive layer; 4, ply of paper; 5, paraffin layer; 6, transparent polyethylene layer.
The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is further described.Following examples only are used for the technical solution of the utility model more clearly is described, and can not limit protection domain of the present utility model with this.
As shown in Figure 1, the utility model provides a kind of inelastic plastic packaging film, this plastic packaging film comprises that upper surface is provided with the thin layer 1 and the ply of paper 4 of printed layers 2, is provided with adhesive layer 3, ply of paper 4, paraffin layer 5 and transparent polyethylene layer 6 successively at thin layer 1 lower surface.Thin layer 1 is plastic sheeting or metallized film, and its thickness is 5 μ m-20 μ m.The thickness of ply of paper 4 is 15 μ m-45 μ m.
Embodiment 1:
Selecting thickness for use is the plastic sheeting of 10 μ m, carries out printing after the corona treatment, makes its upper surface have printed layers 2.Selecting thickness for use is the paper of 25 μ m, the paper lower surface is carried out the applying wax coating handle, and makes its lower surface have paraffin layer 5.The plastic sheeting lower surface is coated with after the gluing upper surface with ply of paper 4 and transparent polyethylene layer 6 carries out compoundly, between plastic sheeting and paper, just formed adhesive layer 3 like this.
Embodiment 2:
Selecting thickness for use is the metallized film of 15 μ m, carries out printing after the corona treatment, makes its upper surface have printed layers 2, the metallized film lower surface is coated with after the gluing carries out compoundly with the thick paper of 30 μ m, has just formed adhesive layer 3 like this between metallized film and the paper.The paper lower surface is carried out the applying wax coating handle, make its lower surface have paraffin layer 5 and transparent polyethylene layer 6.
The above only is a preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
