Technical Field

[0001] This utility model relates to the field of hot pressing technology for BOPP matte release film, specifically a hot pressing device for the production of BOPP matte release film. Background Technology

[0002] BOPP matte release film is a thin film material with a matte texture and release function, made from biaxially oriented polypropylene as the base material and processed through a special process.

[0003] However, existing BOPP matte release films require a long time to dissipate heat when shaped by hot pressing equipment due to their high internal temperature. If the heat dissipation is slow, it can easily lead to a prolonged production changeover cycle and a loss of production capacity. Furthermore, prolonged heat dissipation can also cause a decline in mechanical properties.

[0004] Therefore, in order to solve the above problems, a hot pressing device for the production of BOPP matte release film is proposed. Utility Model Content

However, if the heat dissipation is slow, it will easily cause the production changeover cycle to be extended, resulting in production capacity loss. Furthermore, if the heat dissipation is prolonged, it will also cause the mechanical properties to degrade.
