Abstract
The utility model relates to a three-layer jointly-extruded label film which is characterized by comprising a three-layer structure, namely an upper surface layer, a core layer and a lower surface layer, which are jointly extruded and stretched in double directions, wherein the layer-shaped layout structure of the label film is that a heat sealing layer is adopted as the upper surface layer, a foaming layer is adopted as the core layer, and a corona layer is adopted as the lower surface layer. The three-layer jointly-extruded label film has the advantages that the processing technology is simplified, the manufacturing cost is reduced, the shielding rate is high, the haze is great, the surface printing effect is good, the stiffness of a thin film is good, the surface glossiness is excellent, any harmful substance in the production process is prevented from generating, the environment pollution is avoided, the label film after being used can be recovered fully to manufacture other plastic products, the energy is saved, the using cost of users is reduced, and the economic and social benefits are remarkable.
Description
Technical field
The utility model belongs to field of packaging material, particularly relates to a kind of three-layer co-extruded label film.
Background technology
At present, the base material that is widely used in packaging for foodstuff or label adopt mostly paper compound or mould compound, promptly with paper wood or with plastic sheeting as base layer structure; For obtaining the exquisite visual impression that covers; Brighten layer in one surface or two compound again one decks in surface, and be raw material with polyethylene (PE), after adopting combination process or drenching membrane process processing on its another surface; Obtain heat cover and make above-mentioned packing or label substrate; But above-mentioned compound, drench that explained hereafter efficient such as film is low, energy consumption is big, processing cost is high, and cause environmental pollution aborning, this waste and environmental protection to resource all can produce adverse influence.In addition, not recyclable other plastic products of making of the film after the use not only waste energy, but also have increased user's use cost.
Summary of the invention
But the utility model provides a kind of one-shot forming, screening rate height, non-environmental-pollution, energy savings for solving the technical problem that exists in the known technology, and can reduce the three-layer co-extruded label film of user's use cost.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
Three-layer co-extruded label film; It is characterized in that: comprise upper epidermis, sandwich layer and following top layer three-decker through the coextrusion biaxial tension; The layered arrangement structure of said label film is followed successively by: said upper epidermis is a hot sealing layer, and said sandwich layer is foaming layer, and said top layer down is the corona layer.
The utility model can also adopt following technical scheme:
The thickness on said upper epidermis, following top layer is 4～20% of label film gross thickness.
Advantage and the good effect that the utlity model has are: because the utility model adopts technique scheme; The upper epidermis, sandwich layer and the following top layer that are this label film are all through the heat-sealing one-shot forming; In manufacturing process, need not again compound or drench technology such as film; Simplify processing technology, reduced manufacturing cost; Screening rate is high, mist degree is big, surface printing is effective, the film deflection is good, lustrous surface property is good; Can not produce any harmful substance, non-environmental-pollution in the production process; Label film after the use can all reclaim makes other plastic products, and energy savings reduces user's use cost, and economic and social benefit is remarkable.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: 1, upper epidermis; 2, sandwich layer; 3, following top layer.
The specific embodiment
For further understanding summary of the invention, characteristics and the effect of the utility model, the following examples of giving an example now, and conjunction with figs. specifies as follows:
See also Fig. 1; Three-layer co-extruded label film; Comprise upper epidermis 1, sandwich layer 2 and following top layer 3 three-deckers through the coextrusion biaxial tension, the layered arrangement structure of said label film is followed successively by: upper epidermis 1 is the corona layer for hot sealing layer, sandwich layer 2 for foaming layer and following top layer 3.The material of said upper epidermis 1 is that COPP adds an amount of anti stick masterbatch; Sandwich layer 2 adds an amount of antistatic master batch and smooth masterbatch for foaming layer; The material on following top layer 3 is an amount of anti stick masterbatch for the HOPP resin adds.The thickness on said upper epidermis 1 and following top layer 3 is 4～20% of label film gross thickness.The upper epidermis of this label film, sandwich layer and following top layer be all through the heat-sealing one-shot forming, in manufacturing process, need not compound again or drench technology such as film, simplified processing technology, reduces manufacturing cost; Screening rate is high, mist degree is big, surface printing is effective, the film deflection is good, lustrous surface property is good; Can not produce any harmful substance, non-environmental-pollution in the production process.
