Abstract
The utility model discloses a heat sealing BOPP matt film, which is characterized in that a heat sealing film layer serves as a bottom layer, a matt film layer serves as a surface layer, an antistatic homopolymer polypropylene film layer serves as a center layer, and the heat sealing film layer, the matt film layer and the antistatic homopolymer polypropylene film layer are co-extruded to form a BOPP film. Advantages of a BOPP heat sealing film and a BOPP matt film are combined in the heat sealing BOPP matt film which is capable of not only heat sealing but also matting as a packaging film of BOPP food.
Description
Technical field
The utility model relates to a kind of film, more specifically says so to relate to a kind of polypropylene film that heat sealability has extinction effect again that promptly has.
Background technology
The BOPP matt film is one of basic kind of bidirectional stretching polypropylene film, is the compound and packaging material of a kind of fashion, top grade, and it can give people's vision with soft, comfortable, dim effect.The principle that matt film produces delustring is the top layer that the delustring material joins film, and drawn makes the film surface alligatoring, thereby light is produced scattering process, plays extinction effect.
The BOPP heat-sealing film greatly reduces polyacrylic fusing point because its top layer is a COPP, has heat sealability, can directly seal bag, have environmental protection, easy to use, save advantage such as cost.
But common BOPP matt film does not have heat sealability, and common BOPP heat-sealing film does not have extinction effect yet.Downstream producer must be with BOPP matt film and the compound bag that carries out again of PE film when using the matt film bag.
The utility model content
The utility model is for fear of above-mentioned existing in prior technology deficiency, a kind of BOPP matt film that can directly seal is provided, advantage in conjunction with BOPP matt film and BOPP heat-sealing film, not only can directly seal but also have extinction effect, give the film multifunctionality, reduced the use cost of downstream producer.
The utility model adopts following technical proposals: a kind of BOPP matt film with heat sealability, form three layers of compound structure through co-extrusion, and described three layers of compound structure are: bottom is a hot sealing layer, and the top layer is the delustring layer, and intermediate core layer is an antistatic layer.
Described bottom hot sealing layer, its material are the multi-component copolymer polypropylene; Intermediate core layer, its material adopt membrane level HOPP, top layer delustring layer, and its material is the delustring material, described delustring material is carrier with the HOPP.
The thickness of described hot sealing layer is 0.9-1.2 μ m.
The thickness of described intermediate core layer is 15-22 μ m.
The thickness of described delustring layer is 1.1-2.0 μ m.
Described bottom and top layer have a face at least through sided corona treatment.
The beneficial effects of the utility model: the function of BOPP heat-sealing film and two kinds of films of BOPP matt film is combined together, realize that two kinds of functions, film had both had heat sealability and had and have extinction effect on a kind of film, reach the purpose that reduces the downstream cost.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the utility model compound structure layer schematic diagram.
The specific embodiment
The utility model forms the composite bed film of three-layer structure after coextrusion of BOPP film line and biaxial tension, bottom 3 is a hot sealing layer, and top layer 2 is the delustring layer, and intermediate core layer 1 is an antistatic layer.
Bottom 3 hot sealing layers, its material adopts the multi-component copolymer polypropylene; Intermediate core layer, its material adopt membrane level HOPP, top layer delustring layer, and its material is the delustring material, the delustring material is carrier with the HOPP.The thickness of heat sealing film layer is 1.2-1.5 μ m.
The heat-sealing temperature of heat sealing film layer 3 is 100-130 ℃, and thickness is 0.9-1.2 μ m.The thickness of intermediate core layer 1 is 15-22 μ m.Delustring layer 2 is thick to be 1.1-2.0 μ m.The utility model one or both sides all can carry out sided corona treatment.
Claims (6)
1. the BOPP matt film with heat sealability forms three layers of compound structure through co-extrusion, and it is characterized in that described three layers of compound structure are: bottom is a hot sealing layer, and the top layer is the delustring layer, and intermediate core layer is an antistatic layer.
2. the BOPP matt film with heat sealability according to claim 1 is characterized in that described bottom hot sealing layer, and its material is the multi-component copolymer polypropylene; Intermediate core layer, its material adopt membrane level HOPP, top layer delustring layer, and its material is the delustring material, described delustring material is carrier with the HOPP.
3. the BOPP matt film with heat sealability according to claim 1 and 2, the thickness that it is characterized in that described hot sealing layer are 0.9-1.2 μ m.
4. the BOPP matt film with heat sealability according to claim 1, the thickness that it is characterized in that described intermediate core layer are 15-22 μ m.
5. according to claim 1 or 4 described BOPP matt films with heat sealability, the thickness that it is characterized in that described delustring layer is 1.1-2.0 μ m.
6. the BOPP matt film with heat sealability according to claim 1 is characterized in that described bottom and top layer have a face at least through sided corona treatment.
