Paper bag

Abstract

The invention discloses a paper bag which is formed by folding paper plates for box making. An unfolding plane can be a bottom plate, a front panel and a back panel, a left panel and a right panel, wherein the bottom plate is formed by segmenting creases; the front panel and the back panel are respectively connected with the creases at the two long sides of the bottom plate; the left panel and the right panel are respectively connected with the creases at the two short sides of the bottom plate; the left panel and the right panel are respectively provided with symmetric folding edges connected with the two creases between the front panel and the back panel; the folding edges at one side of the left panel is sequentially overlapped on the left panel; the left side plate and the folding edge overlapped at the outermost layer of the left panel are provided with snap fasteners correspondingly connected with each other; the folding edges at one side of the right panel are sequentially overlapped on the right panel; and the right side plate and the folding edge overlapped at the outermost layer of the right panel are provided with snap fasteners correspondingly connected with each other. Four side plates and the bottom plate are connected to form an integral paper bag, and therefore, the paper bag is firm in structure and saves the production and transportation costs. When the paper bag is not used, the snap fasteners are released and a plurality of unfolded paper bags can be placed in an overlapping way, so that the paper bag is convenient to accommodate.

Description

technical field [0001] The invention belongs to the technical field of packaging, in particular to a paper bag. Background technique [0002] In daily life, paper bags are often used as packaging for daily necessities. Paper bags are not only low in cost, but also because the paper is taken from nature, it is a recyclable, renewable, and reusable material, which does not cause environmental pollution and is conducive to environmental protection. [0003] Paper bags usually have glued seals on the side or bottom surface. The folding and glue processing of such paper bags need to be completed during production, and the process is complicated. And for the paper bag made of hard paper, it is transported after processing, which takes a large transport space and high transport cost. [0004] When the placed items are heavy, the adhesive-sealed paper bags are prone to degumming due to the insufficient glue force due to the heavy items; at the same time, the adhesive-sealed paper b...
