At present, the embossing leather on the surfaces at home and abroad is directly unreeled for embossing the PVC film, however, the PVC film can be stretched and deformed in the embossing process, one surface of the PVC film cannot be provided with patterns after embossing, the other surface of the PVC film is smooth, and the embossing patterns are not clear enough, so that the requirements of customers and users cannot be met.
Disclosure of utility model
In order to overcome the defects of the prior art, the utility model provides the PET film backing laminating embossing PVC film, which can effectively solve the technical problems that the embossing leather on the surfaces at home and abroad is directly unreeled PVC film embossing, the PVC film can be stretched and deformed in the embossing process, one surface of the PVC film cannot be provided with patterns after embossing, the other surface of the PVC film is smooth, and the embossing is not clear enough.
The technical scheme adopted for solving the technical problems is as follows: the utility model provides a PET membrane holds in palm laminating knurling PVC membrane, includes the PVC membrane body, the PVC membrane body includes PVC rete and PET holds in the palm the collet rete, the PVC rete is located the PET holds in the palm collet rete's top, just PET holds in the palm collet rete and PVC rete laminating each other and is connected, the surface of PVC rete is equipped with the knurling.
Preferably, the embossing pattern is arranged on the surface of one side, far away from the PET backing film layer, of the PVC film layer.
Preferably, the PET support bottom film layer is connected with the PVC film layer through electrostatic adsorption.
Preferably, the PET backing film layer is composed of biaxially oriented BOPET film, and the thickness of the PET backing film layer is 20-25 μm.
Preferably, the thickness of the PVC film layer is 200-650 mu m, and the plasticizer content of the PVC film layer is 40-60%.
Compared with the prior art, the utility model has the beneficial effects that:
Through setting up the PET in the below of PVC rete and hold in the palm the backing rete, consequently, can suitably improve big jar temperature, make it do benefit to laminating and subsequent knurling technology more, the PVC rete can reduce tensile deformation by a wide margin in the in-process that carries out knurling technology for the knurling is more clear, and the bottom of PVC rete is owing to receive the protection of PET and hold in the palm the backing rete, so can realize that the one side of PVC membrane is the effect that has the decorative pattern, and the other side of PVC membrane is smooth.
