Abstract
The utility model relates to a five-layer high non-transparency pearlized film. The five-layer high non-transparency pearlized film is characterized in that the pearlized film includes a five-layer structure formed by co-extrusion and consisting of a biaxial stretching upper surface layer, an upper subsurface layer, a core layer, a lower subsurface layer and a lower surface layer, wherein the upper surface layer is a non-heat-seal layer; the upper subsurface layer is a pearlized layer; the core layer is a foamed layer; the lower subsurface layer may be a pearlized layer or a non-transparent layer; and the lower surface layer is a heat-seal layer. The surface layers, the subsurface layers and the core layer are formed by one-step co-extrusion to obviate the recombination during manufacture, thereby simplifying the manufacture process, lowering the manufacture cost, and obviating environment pollution during manufacture. The used pearlized film can be recycled to manufacture other plastic products, thereby lowering the use cost.
Description
Technical field
The utility model belongs to a kind of plastic wrapping, particularly relates to a kind of high opacity pearly-lustre film that is used for packings such as food, tableware, amenities.
Background technology
Being widely used in packings such as food, tableware, amenities at present adopts coextrusion pearly-lustre film mostly and moulds complex film.Because existing coextrusion pearly-lustre film is a three-decker, is subject to processing the restriction of technological condition, the opacity of pearly-lustre film is lower, can't reach splendid pearly-lustre visual effect; In order to improve the opacity of pearly-lustre film, generally adopt and mould combination process, promptly with plastic sheeting as endothecium structure, the pearly-lustre film as skin through applying solvent and the compound said products that makes of internal layer, thisly mould the opacity that complex pocket has improved the pearly-lustre film, but the consumption of water, electricity, vapour is bigger in compound production process, the tooling cost height, and cause environmental pollution aborning.Mould in addition combined package bag be subject to factor affecting such as complex condition, storage environment and layering appears, problem such as break, so not only influence result of use, but also can bring corresponding economic loss to the user.
Summary of the invention
The utility model for solve the technical matters that exists in the known technology provide a kind of can one time co-extrusion modling, high opaque, the attractive in appearance and high opacity pearly-lustre of suitable industrial continuous production film.
The technical scheme that the utility model is taked for the technical matters that exists in the solution known technology is: five floor height opacity pearly-lustre films, it is characterized in that: comprise upper epidermis through the coextrusion biaxial tension, last time top layer, sandwich layer, next top layer, top layer five-layer structure down, the layered arrangement structure of described pearly-lustre film is:
A, upper epidermis (1) are non-hot sealing layer, and top layer last time (2) is a pearl layer, and sandwich layer (3) is foaming layer, and next top layer (4) are pearl layer, and following top layer (5) is a hot sealing layer;
B, upper epidermis (1) are non-hot sealing layer, and top layer last time (2) is a pearl layer, and sandwich layer (3) is foaming layer, and next top layer (4) are opaque layer, and following top layer (5) is a hot sealing layer;
C, upper epidermis (1) are non-hot sealing layer, and top layer last time (2) and next top layer (4) are pearl layer, and sandwich layer (3) is foaming layer, and following top layer (5) is a hot sealing layer;
D, upper epidermis (1) are non-hot sealing layer, and sandwich layer (3) is foaming layer, and top layer last time (2) and next top layer (4) are pearl layer, and following top layer (5) is a hot sealing layer;
E, upper epidermis (1) are non-hot sealing layer, and sandwich layer (3) is foaming layer, and top layer last time (2) is a pearl layer, and next top layer (4) are opaque layer, and following top layer (5) is a hot sealing layer.
Advantage and the good effect that the utlity model has are: since upper epidermis of the present utility model, last time top layer, sandwich layer, next top layer, the top layer is all by a co-extrusion modling down, through changing runner, increase pearl layer thickness, make the pearly-lustre film of processing have the advantage of higher opacity, splendid pearly-lustre visual effect; In manufacturing process, need not again compoundly, simplified processing technology, reduce manufacturing cost; All production process can not produce any objectionable impurities, and non-environmental-pollution, the pearly-lustre film after the use can all reclaim makes other plastic product.
