Abstract
The utility model relates to a five-layer coextrusion pearl film, which is characterized by comprising a five-layer structure of an upper surface layer, a secondary upper surface layer, a core layer, a secondary lower surface layer and a lower surface layer which undergo coextrusion biaxial tension, wherein the five layers of the pearl film are sequentially distributed in a laminated structure: the upper surface layer is a hot-seal layer, the secondary upper surface layer is a whitening layer, the core layer is a pearl layer, the secondary lower surface layer is the whitening layer, and the lower surface layer is a corona layer. The utility model has the advantages that: the pearl film has a good pearl effect, a high shielding rate, large haze, a good surface printing effect, good film stiffness, excellent surface glossiness, good smoothness and an anti-static effect, and is applicable to high-speed production lines; and the whole production process does not produce any harmful substance, so the environment is not polluted, and the used pearl film can be completely recycled to produce other plastic products, so the energy is saved, and the use cost of users is also reduced.
Description
Technical field
The utility model belongs to plastic sheeting manufacturing technology field, particularly relates to a kind of five-layer co-squeezing pearl film.
Background technology
The base material that is widely used in packaging for foodstuff or label at present adopts paper compound or mould compound mostly; promptly with paper wood or with plastic sheeting as base layer structure; for obtaining exquisite pearl visual impression; brighten layer in one surface or two surface recombination one decks; and be raw material with polyethylene (PE) on its another surface; after adopting combination process or drenching membrane process processing; obtain heat cover and make above-mentioned packing or label substrate; this type of composite base material has pearl vision preferably; function such as heat sealable; but in papermaking; compound; production efficiency is low in the pouring film production process; energy consumption is big; the processing cost height; 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
The technical problem that exists in the known technology provides a kind of screening rate height to the utility model, mist degree is big, pearl effect good in order to solve, energy-saving and cost-reducing and suitable industrial continuous production five-layer co-squeezing pearl film.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
Five-layer co-squeezing pearl film, it is characterized in that: comprise upper epidermis through the coextrusion biaxial tension, last time top layer, sandwich layer, next top layer and following top layer five-layer structure, the layer structure layout of described pearl film is followed successively by: upper epidermis be hot sealing layer, last time the top layer for to brighten layer, sandwich layer be nacre, next top layer for brighten layer, time top layer is the corona layer.
The utility model can also adopt following technical scheme:
Described upper epidermis, last time, the thickness on top layer, next top layer and following top layer was 4～20% of pearl film gross thickness.
Advantage and the good effect that the utlity model has are: because the utility model adopts technique scheme, the top layer of pearl film, inferior top layer and sandwich layer are the coextrusion mold structure one time, in manufacturing process, need not again compound, drench technology such as film, simplified processing technology, reduce manufacturing cost.Make the pearl film of coextrusion have that pearl effect is excellent, screening rate is high, mist degree is big, surface printing is effective, the film deflection is good, lustrous surface is good, good smooth, antistatic effect are fit to high-speed production lines to be used; All production processes can not produce any harmful substance, and non-environmental-pollution, the pearl film after the use can all reclaim makes other plastic products, but energy savings not only, but also reduced user's use cost.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, upper epidermis; 2, last time the top layer; 3, sandwich layer; 4, next top layer; 5, following top layer.
The specific embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1, five-layer co-squeezing pearl film, comprise upper epidermis through the coextrusion biaxial tension, last time top layer, sandwich layer, next top layer and following top layer five-layer structure, the layered arrangement structure of described pearl film is followed successively by: upper epidermis 1 for hot sealing layer, last time top layer 2 for brighten layer, sandwich layer 3 for nacre, next top layer 4 for brighten layer, following top layer 5 is the corona layer.Described upper epidermis 1 adds an amount of caking inhibiter for the heat-sealing masterbatch; Last time, top layer 2 was for brightening masterbatch; Sandwich layer 3 is 100% an amount of antistatic master batch and the smooth masterbatch of pearl masterbatch adding; Next time, top layer 4 was for brightening masterbatch; Following top layer 5 is an amount of anti stick masterbatch for the HOPP resin adds.Described upper epidermis, last time the top layer, the thickness on top layer and next top layer is respectively the 4-20% of pearl film gross thickness down.
