Abstract

The invention belongs to the technical filed of production of a plastic film, and concretely discloses a plastic packaging bag slaking examination method. The method comprises the following steps: 1)material preparation: rolling a composited plastic packaging film; 2) slaking treatment: placing the rolled plastic packaging film in a slaking room for slaking treatment at the slaking temperature being 40-45 DEG C for 24-30 h; and 3) slaking examination: taking the plastic packaging film after slaking is completed, cutting the plastic packaging film with a cutting length being 1-1.2 m and a unchanged width, then placing the plastic packaging film in a baking oven at the temperature of 78-83 DEG C for heating for 28-33 min, and inspecting the appearance of the plastic packaging film after heating is completed, if the bubbles are not generated on the surface of the plastic packaging film, slaking accords with requirements. The examination method can rapidly detect whether slaking of the plastic packaging film is qualified or not, and production efficiency is accelerated.

Description

technical field [0001] The invention belongs to the technical field of plastic film production, and in particular relates to a method for checking the aging of plastic packaging bags. Background technique [0002] In the pharmaceutical industry, it involves packaging the prepared pharmaceuticals. The packaging mainly includes bags and aluminum foil boards. No matter what kind of packaging is used, it involves film preparation, printing, compounding, aging, heat sealing and bag making. Among them, aging is the key process in the process of preparing clinker packaging bags, which has an important impact on the barrier properties and transparency of clinker packaging bags. [0003] The curing of plastic packaging is also called curing. It is the process of putting the composite film into the drying room (curing room) to make the main agent and curing agent of the polyurethane adhesive react and crosslink and interact with the surface of the composite substrate. The main purpos...
