High surface tension non-corona BOPA film roll

Abstract

The invention relates to a high surface tension non-corona BOPA film roll which is a 20-30 micron of film roll prepared by extruding, stretching, rewinding and slitting BOPA raw materials; the BOPA raw materials are prepared based on mass fraction from evenly mixing 75-83 parts of PA6, 5-12 parts of polyamide modified nanometer silicon dioxide, 1-3 parts of palm wax, 1-2 parts of antistatic agent and 1-5 parts of other assistants; and the polyamide modified nanometer silicon dioxide is prepared based on mass percent from 1-2% of silane coupling agent, 2-5% of palm wax, 10-13% of nanometer silicon dioxide powder and the balance of PA6.The high surface tension non-corona BOPA film roll provided by the invention is doped with silicon dioxide in BOPA, so that the surface tension may reach 48 dyne, which effectively improves the surface tension of the non-corona BOPA film roll, and attenuation of the surface tension is slow, and special requirements of the client are met.

Description

technical field [0001] The invention relates to the field of BOPA film, in particular to a high surface tension non-corona BOPA film roll. Background technique [0002] The surface tension of the non-corona surface of the existing film roll can only reach 38 dynes, which is too low, which cannot meet the customer's requirements for the surface tension of the non-corona surface, and as time goes by, the surface tension decays quickly due to the different storage environments. Affect. Contents of the invention [0003] The invention provides a high surface tension non-corona BOPA film roll, the surface tension can reach 48 dynes, effectively improve the surface tension of the non-corona BOPA film roll, the surface tension decays slowly, and meet the special needs of customers. [0004] A high surface tension non-corona BOPA film roll, which is a 20-30 micron film roll prepared by extruding, stretching and rewinding slits from BOPA raw materials; the BOPA raw material is com...
