Abstract
The utility model relates to a multi-layer co-extrusion heat-seal type pearly-luster film which is characterized in that: the multi-layer co-extrusion heat-seal type pearly-luster film comprises an upper surface layer, an upper secondary surface layer, a core layer, a lower secondary surface layer and a lower surface layer which are stretched through co-extrusion in a bidirectional manner; and the layered layout structure of the multi-layer co-extrusion heat-seal type pearly-luster film is as follows: the upper surface layer is a heat-seal layer, the upper secondary surface layer is a whitening layer, the core layer is a pearly-luster layer, the lower secondary surface layer is also a whitening layer, and the lower surface layer is a corona layer. The multi-layer co-extrusion heat-seal type pearly-luster film has the following advantages: the process is simplified, and the manufacturing cost is low; the pearly-luster film has fine pearly-luster visual enjoyment, high heat-seal intensity, low heat-seal temperature, good antistatic effect, good opening property, firm surface printing, light weight and good weather enduring property; as any harmful substance cannot be generated in the whole production process, no environmental pollution can be caused; as the pearly-luster film can be entirely recycled for manufacturing other plastic products after being used, energy resources are saved and the using cost of users is reduced.
Description
Technical field
The utility model belongs to the plastic sheeting technical field, particularly relates to a kind of multi-layer co-extruded heat sealable type pearly-lustre 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 pearly-lustre 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 preferably pearly-lustre vision and 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
But the utility model provides a kind of one-shot forming, heat seal strength height, saves energy and reduce the cost, alleviates environmental pollution and the multi-layer co-extruded heat sealable type pearly-lustre film of suitable industrial continuous production for solving the technical problem that exists in the known technology.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is: multi-layer co-extruded heat sealable type pearly-lustre 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 layered arrangement structure of described multi-layer co-extruded heat sealable type pearly-lustre film is: upper epidermis be hot sealing layer, last time the top layer for to brighten layer, sandwich layer be pearl layer, 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 respectively 4～20% of heat-sealing film gross thickness.
Advantage and the good effect that the utlity model has are: because the utility model adopts technique scheme, each top layer of this pearly-lustre film, each time top layer and sandwich layer are by the co-extrusion one-shot forming, in manufacturing process, need not again compound, drench technology such as film, simplified processing technology, reduce manufacturing cost; Make the pearly-lustre film that processes have exquisite pearly-lustre vision, the heat seal strength height, heat-sealing temperature is low, antistatic effect good, opening is good, surface printing is firm, light weight, weatherability are good; All production processes can not produce any harmful substance, and non-environmental-pollution, the pearly-lustre 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, multi-layer co-extruded heat sealable type pearly-lustre film, comprise upper epidermis 1 through the coextrusion biaxial tension, last time top layer 2, sandwich layer 3, next top layer 4 and following top layer 5 five-layer structures, the layered arrangement structure of described pearly-lustre film is followed successively by: upper epidermis 1 is hot sealing layer, last time, top layer 2 was for brightening layer, sandwich layer 3 is a pearl layer, and next top layer 4 is for brightening layer, and following top layer 5 is the corona layer.Described upper epidermis 1 adds an amount of slipping agent and 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 of pearly-lustre masterbatch adding; Next top layer 4 is an amount of anti stick masterbatch for the HOPP resin adds, and following top layer 5 is for brightening masterbatch.Described upper epidermis, last time the top layer, the thickness on top layer and next top layer is respectively the 4-20% of pearly-lustre film gross thickness down.
