Abstract
The utility model relates to a biaxial tension polypropylene basement membrane utilized to the laser coining transferring. The basement membrane consists of an upper surface layer, a core layer and a lower surface layer, the upper surface layer, the core layer and the lower surface layer are became a whole through heat melt and together nip. The lower surface layer is a transfer layer. The thickness of the upper surface layer and the lower surface layer of the basement membrane are the 10 percent to 12 percent of the thickness of the basement membrane. The utility model has advantages that because of the rational structure and the novel design, the utility model can direct transfer the laser coining. The utility model not only can satisfy the laser effect, the evaporation effect and the transfer effect the custom requires, and greatly reduce the cost of the product.
Description
Affiliated technical field
The utility model relates to a kind of polypropylene basement membrane of novel use, especially for the bidirection drawed BOPP film of laser imprinting transfer.Utilize this kind basement membrane can process product with laser effect, and by radium-shine transfer, thereby reach packaged commodity decoration, decoration or antifalse effect.
Background technology
At present, the known transfer basement membrane that is used to produce laser imprinting evaporation goods is the basement membrane of being produced by polyester plastics (PET), polyethylene non-PP (HOPP) raw materials such as (PE).Utilize this type of basement membrane to impress evaporation and radium-shine transfer, finally can reach decoration, decoration or false proof effect packaged commodity.But this type of basement membrane can not directly use, and necessary compound one deck embossed layer just can carry out laser imprinting during use, and compound again one deck transfer layer can be realized radium-shine transfer purposes.In addition, produce that the used prices of raw and semifnished materials are expensive, equipment performance require high, the production cost height.Like this, reduce product cost, widen product applications and brought unsurmountable defective for downstream user.
Summary of the invention:
The purpose of this utility model is, can not directly lead at existing radium-shine transfer basement membrane and to carry out laser imprinting and shift, the deficiency of necessary compound last layer embossed layer, improve, propose not count the polypropylene basement membrane of the biaxial tension that is used for the laser imprinting transfer, this kind basement membrane can directly carry out laser imprinting to be shifted.Thereby for downstream user reduces product cost, widened product applications,
Technical solution scheme of the present utility model is, basement membrane is by upper epidermis, sandwich layer, the top layer constitutes down, and upper epidermis, sandwich layer, the top layer becomes one by the hot melt co-extrusion down, and sandwich layer is at upper epidermis, down between the top layer, and wherein descending the top layer is transfer layer.
The thickness on upper epidermis, following top layer is respectively the 10%-12% of basement membrane thickness.
The utility model has the advantages that because it is rational in infrastructure, modern design can directly be carried out the laser imprinting evaporation and be shifted, it not only can satisfy the desired laser effect of user, evaporation effect and transfer effect, greatly reduces the cost of product simultaneously.
Description of drawings
Fig. 1, vertical structure schematic diagram of the present utility model.
Fig. 2, transversary cut-away view of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As shown in Figure 1 and Figure 2, the utility model is made of upper epidermis 1, sandwich layer 2, following top layer 3, and upper epidermis 1, sandwich layer 2, following top layer 3 form one by equipment hot melt, co-extrusion, and sandwich layer 2 is between upper epidermis 1, following top layer 3, and wherein, following top layer 3 is a transfer layer.The thickness on upper epidermis 1, following top layer 3 is respectively the 10%-12% of basement membrane thickness.The material on the upper epidermis 1 of formation basement membrane, sandwich layer 2, following top layer 3 mainly adopts polypropylene plastics.
Basement membrane can cut into the finished product of different specification size (length and width) according to user's different requirement.Also can utilize different stretch processes to produce the basement membrane of different-thickness.
Claims (2)
1, be used for the bidirection drawed BOPP film that laser imprinting shifts, it is characterized in that, basement membrane is made of upper epidermis (1), sandwich layer (2), following top layer (3), and sandwich layer (2) is positioned between upper epidermis (1), the following top layer (3), and following top layer (3) is a transfer layer.
2, the bidirection drawed BOPP film that is used for the laser imprinting transfer according to claim 1 is characterized in that, the thickness on upper epidermis (1), following top layer (3) is respectively the 10%-12% of basement membrane thickness.
