Problems solved by technology

The disadvantage is that BOPET is selective to ink, and the printability is not as good as BOPP; the density is 1.41g / cm 3 , the same surface area unit cost ratio BOPP (density 0.905g / cm 3 )high
Ordinary biaxially oriented polypropylene film cannot be used for leather printing transfer because ordinary biaxially oriented polypropylene film has a gap with BOPET in terms of stiffness and heat shrinkage
At the same time, in the process of producing biaxially oriented polypropylene film, in order to prevent the film from sticking, an anti-adhesive agent must be added to the surface layer, and the general-purpose anti-adhesive agent is a synthetic silica, which is easy to scratch the ink or aluminum layer during the process of transferring ink or aluminum layer , affecting the transfer quality

Abstract

The invention discloses BOPP film for leather printing transfer and a manufacturing method thereof which belong to the technical field of BOPP film processing; the film comprises an upper surface layer, a core layer and a lower surface layer; the upper surface layer is prepared from the following components by weight percentage: 98 to 99 percent of homopolymer polypropylene and 1 to 2 percent of anti-adhesive; the core layer is prepared from the following components by weight percentage: 87.5 to 93.2 percent of homopolymer polypropylene, 0.8 to 1.5 percent of antistatic agent, 2 to 3 percent of transfer agent and 4 to 8 percent of nucleating agent; and the lower surface layer is prepared from the following components by weight percentage: 97 to 98 percent of homopolymer polypropylene and 2 to 3 percent of anti-adhesive. Compared with traditional BOPP film, the BOPP film for leather printing transfer has higher elastic modulus and lower heat shrinkage rate, and can replace bi-oriented polyethylene terephthalate film and be applied to the field of printing transfer.

Description

technical field [0001] The invention relates to a biaxially oriented polypropylene film used for leather printing and transfer and a manufacturing method thereof, belonging to the technical field of biaxially oriented polypropylene film processing. Background technique [0002] In order to obtain the functions of rich color, fineness, dazzling brilliance, durability, wear resistance and high temperature resistance of leather, it is generally necessary to print on the surface. Stretch polyethylene terephthalate (BOPET) film as the base material is made of gravure coating, printing, vacuum aluminizing and back-coating hot sol (thermal adhesive). It can be heated and pressurized. The method transfers the aluminum layer and color to the base material such as leather and textile, thereby changing the appearance and quality of the base material, and playing the role of improving the grade of the product. BOPET film is used as the substrate because of its high stiffness (a perform...
