Abstract
The utility model discloses a BOPET (biax orientation polyester film) tangle film capable of being directly subjected to shallow lattice printing. In the film, a polyester anti-adhesion layer is used as a bottom layer, a shallow lattice printing layer is used as a surface layer, transparent polyester is used as an intermediate core layer, and the three layers are subjected to coextrusion to form the BOPET tangle film. In the utility model, the characteristics of the BOPET tangle film and the characteristics of a BOPET shallow lattice printing film are combined, so that the BOPET tangle film has double functions that the BOPET tangle film not only can be used for carrying out shallow lattice printing, but also can be used for carrying out food tangle packaging.
Description
Technical field
The utility model relates to a kind of plastic food packing film, more specifically say so relate to a kind of can be used for shallow reticulated printing can twist together again the packing biaxial tension pet film (BOPET film).
Background technology
The packing film of food kink in the market is mainly the PVC torsion film, but because the security of PVC, the torsion film material develops to PETG (PET) gradually.PET has good kink effect and the performance of aluminizing, but common BOPET film can not carry out shallow reticulated printing, can produce when carrying out shallow reticulated printing and lose a phenomenon.
The film of shallow reticulated printing can carry out complicated intaglio printing, and chromatography is accurate, and color transition is level and smooth, and is beautiful in colour, the stereovision distinctness, and printed patterns is true to nature.The common BOPET film that can the carry out shallow reticulated printing packing of can not twisting together, its kink resilience is big, and duration is short, can't pack by the kink mode.
Summary of the invention
All have the problem of function singleness at two kinds of films in the above-mentioned prior art, the purpose of this utility model is to provide a kind of film, and it has dual-use function, promptly gives the BOPET torsion film and can directly carry out the shallow reticulated printing effect.
The utility model adopts following technical proposals: a kind of BOPET torsion film that can directly carry out shallow reticulated printing, form the three-decker of compound structure through co-extrusion, the three-decker of described compound structure is: with the anti-adhering layer of polyester is bottom, with the shallow reticulated printing layer is the top layer, is intermediate core layer with the transparent polyester layer.
Described shallow reticulated printing layer, its material are film level PETG and kaolin, silica-based antiblocking agent; The anti-adhering layer of described polyester, its material adopts membrane level PETG and common antiblocking agent; Described transparent polyester layer, its material adopt membrane level PETG.
The thickness of the anti-adhering layer of described polyester is 1.2-1.5 μ m.
The thickness of described intermediate core layer is 5-15 μ m.
The surface roughness of described shallow reticulated printing layer is 1.0-1.5 μ m.
The thickness of described shallow reticulated printing layer is 1.0-1.2 μ m.
Described shallow reticulated printing layer carries out sided corona treatment.
The beneficial effects of the utility model: the function of two kinds of films is combined together, can on a kind of film, realize two kinds of functions, make the BOPET torsion film can carry out shallow reticulated printing, can carry out food kink packing again, 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 three-decker schematic diagram of the utility model compound structure.
The specific embodiment
The utility model forms the composite bed film of three-layer structure after coextrusion of BOPET film line and biaxial tension, bottom 3 is the anti-adhering layer of polyester, and top layer 2 is the shallow reticulated printing layer, and intermediate core layer 1 is the polyester transparent layer.The anti-adhering layer of bottom 3 polyester, its material adopts membrane level PETG and common antiblocking agent; Top layer 2 shallow reticulated printing layers, its material are film level PETG and kaolin, silica-based antiblocking agent; Intermediate core layer 1 transparent polyester layer, its material adopt membrane level PETG.The thickness of anti-adhering layer is 1.2-1.5 μ m.The kink angle of film is 270 °-360 °.The thickness of intermediate core layer is 5-15 μ m.The surface roughness of shallow reticulated printing thin layer is 1.0-1.5 μ m.The thickness of shallow reticulated printing thin layer is 1.0-1.2 μ m.The shallow reticulated printing face carries out sided corona treatment.
