Logistics bag with self-adhesion and waterproof functions and production method thereof

Abstract

The invention discloses a logistics bag with self-adhesion and waterproof functions and a production method thereof, and relates to the technical field of logistics bag production. The method comprises the steps of mixing, blow molding, printing, bag making and packaging collection, wherein the mixing comprises the following steps: step 1, uniformly mixing rubber, a tackifier, polyvinyl chloride,polyisobutene, polyurethane and other materials according to a ratio to be used as a base material; 2, putting PE particles, black master batch particles, raw materials of other filling materials andthe base material into a same stirring box; and 3, fully stirring the PE particles, the black master batch particles, the raw materials of other filling materials and the base material in the stirringbox for 1 hour. By arranging the rubber, the polyvinyl chloride, the polyisobutene and the polyurethane, the waterproofness of the logistics bag can be improved, objects in the logistics bag are prevented from being affected with damp in a damp environment, and the objects in the logistics bag can be better protected.

Description

technical field [0001] The invention belongs to the technical field of logistics bag production, and in particular relates to a logistics bag with self-adhesive and waterproof functions and a production method thereof.
