Abstract
The utility model relates to a matte heat-sealable pearlized film, which is characterized the pearlized film adopts a structure containing three layers: an upper surface layer, a sandwich layer and a lower surface layer stretching bidirectionally through coextrusion. The pearlized film can adopt three modes of layered structure as follows: (1) the upper surface layer adopts a matte layer, the lower surface layer adopts a heat-seal layer, and the sandwich layer is arranged between the matte layer and the heat-seal layer; (2) the upper surface layer adopts a matte layer, the lower surface layer adopts a non heat-seal layer, and the sandwich layer is arranged between the matte layer and the heat-seal layer; and (3) both the upper and the lower surface layers adopt matte layers, and a sandwich layer is arranged below the two adjacent matte layers. The pearlized film has the advantages that the processing technique is simplified, and the manufacture cost is reduced; the pearlized film has excellent matte effect, high heat-seal intensity, wide heat-seal temperature range, firm surface printing, light weight, and excellent weather resistance; no hazardous material can be produced during the production process, so that environment pollution is avoided. The pearlized film can be recycled after use for manufacturing other plastic products, thereby not only saving energy, but also reducing the use cost of a user.
Description
Technical field
The utility model belongs to the membrane product technical field, particularly relates to a kind of heat sealable type pearly-lustre of inferior light film that is used for packaging for foodstuff base material or label etc.
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 inferior light visual impression; at the compound one deck matt film of one surface; 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 inferior preferably light vision; 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, the energy-saving and cost-reducing and heat sealable type pearly-lustre of the inferior light of suitable industrial continuous production film 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:
The heat sealable type pearly-lustre of a kind of inferior light film is characterized in that: comprise upper epidermis, sandwich layer and following top layer three-decker through the coextrusion biaxial tension, the layer structure of described pearly-lustre film is:
A, described upper epidermis are matt layer, and following top layer is a hot sealing layer, is provided with sandwich layer between matt layer and hot sealing layer;
B, described upper epidermis are matt layer, and following top layer is non-hot sealing layer, are provided with sandwich layer between matt layer and non-hot sealing layer;
C, described upper epidermis and following top layer are matt layer, are provided with sandwich layer below adjacent two matt layers.
The utility model can also adopt following technical scheme:
The thickness on described upper epidermis and following top layer is respectively the 4-15% of pearly-lustre film gross thickness.
Advantage and the good effect that the utlity model has are: because technologies such as that upper epidermis of the present utility model and following top layer all by one-shot forming, need not in manufacturing process again is compound, pouring film have been simplified processing technology, the reduction manufacturing cost; Make the pearly-lustre film that processes have exquisite inferior light vision, advantage such as heat seal strength height, heat-sealing temperature wide ranges, surface printing are firmly, light weight, weatherability be 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.
