Anti-sticking packaging bag

Abstract

The invention discloses an anti-sticking packaging bag. The anti-sticking packaging bag comprises a packaging bag body, the packaging bag body comprises a main bag body, side edges and a bottom edge, a sealing opening is formed in the main bag body, a sealing groove and a sealing strip are arranged at the sealing opening, the sealing groove is matched with the sealing strip, a feeding opening is formed in the top of the main bag body, anti-sticking mechanisms are symmetrically arranged at the top of the feeding opening, the anti-sticking mechanisms comprise adjusting pieces, cavities are formed in the adjusting pieces, first screws and second screws are arranged in the cavities, threads on the first screws and the second screws are reverse threads, the first screws and the second screws are connected through couplers, sliding blocks are arranged on the outer sides of the first screws and the second screws in a threaded connection mode, movable pieces are fixedly arranged on one sides of the sliding blocks, the ends, away from the sliding blocks, of the movable pieces penetrate through the cavities and extend out of the adjusting pieces to be fixedly connected with the outer side wall of the feeding port. The packaging bag has the beneficial effects that through the arrangement of a transparent observation window, a transparent label placement area and a label, people can conveniently classify and distinguish stored articles, so that the articles can be conveniently and quickly found.

Description

technical field [0001] The invention relates to a packaging bag, in particular to an anti-adhesion packaging bag. Background technique [0002] Polymer materials are materials based on polymer compounds. Polymer materials are materials composed of compounds with relatively high molecular weight, including rubber, plastics, fibers, coatings, adhesives and polymer-based composite materials. Polymers are the form of life. All living organisms can be regarded as a collection of macromolecules. [0003] In the use of polymer material packaging bags, because the skin of human hands is relatively dry, and the sealing part of the packaging bag is sticky, it is often difficult to rub the feeding seal of the packaging bag, which brings inconvenience to the use. Moreover, the traditional packaging The structure of the bag is relatively fixed, the firmness is poor, and the airtightness of the seal is also difficult to guarantee, which has certain limitations. [0004] Aiming at the p...
