[sovereignty] 1. A nylon packaging film is added 8. After the test, it is automatically archived, and * strength, yield strength, tensile strength, and modulus of elasticity, elongation The master batch of data such as tortuosity modulus is characterized in that it contains 60 ~ 94% by weight of polyamide carrier resin, 2 ~ 20% by weight of lubricant, 1.5 ~ 10% by weight of anti adhesion agent, 1.5 ~ 10% by weight of nucleating agent, and 0.1 ~ 1.0% by weight of coupling agent
[cd-rom no. of instructions] d
[Abstract] the invention discloses a processing master batch for nylon packaging film, which consists of (in weight percentage): polyamide 60 ~ 94%, lubricant 2 ~ 20%, anti adhesion agent 1.5 ~ 10%, nucleating agent 1.5 ~ 10%, coupling agent 0.1 ~ 1.0%. The processing method of the masterbatch of the invention is as follows: after the anti adhesion agent and nucleating agent are pretreated by coupling and dispersant, polyamide, lubricant, anti adhesion agent and nucleating agent are weighed in proportion, 1.5 ~ 10% are evenly mixed, and then the optical granular masterbatch is extruded by the co rotating twin-screw extruder at the temperature of 210 ℃ ~ 250 ℃. The film produced by the masterbatch of the invention can reduce the frequency of film breaking, improve the transparency, thermal shrinkage, smoothness and other properties of the finished film, and is especially suitable for the food packaging industry
