【Abstracts】 The invention discloses a processing masterbatch for nylon packaging film, the composition of which is (by weight percent): polyamide 60 to 94%, lubricant 2 to 20%, anti-blocking agent 1.5 to 10%, The nucleating agent is 1.5 to 10% and the coupling agent is 0.1 to 1.0%. The method for processing the masterbatch according to the invention comprises: after the anti-blocking agent and the nucleating agent are pretreated by a coupling agent and a dispersant, the polyamide, the lubricant, the anti-blocking agent and the nucleating agent are weighed in a ratio of 1.5 to 10% uniformly mixed; After the temperature of 210 °C ~ 250 °C under the co-rotating twin-screw extruder into a granular masterbatch. The masterbatch production film of the invention can reduce the frequency of film breakage, improve the transparency, heat shrinkage and smoothness of the finished film, and is particularly suitable for the food packaging industry.
