Abstract

The invention belongs to the technical field of woven bags and particularly relates to a plastic woven bag with a BOPP film for food packaging. The plastic woven bag comprises a base, a support spring, a spiral cloth bag, a clamping unit, a bottom closing unit and a lifting unit, wherein the base is in a shape of a disc, the spiral cloth bag is arranged at the upper part of the base, the support spring is arranged at the inner side of the spiral cloth bag, the support spring is used for opening the spiral cloth bag, the clamping unit is arranged between the spiral cloth bag and the support spring, the bottom closing unit is arranged between the base and the support spring, the lifting unit is arranged at the upper part of the base, and the lifting unit is used for lifting or lowering the support spring. Through the cooperation of the base, the support spring, the spiral cloth bag, the clamping unit, the bottom closing unit and the lifting unit, the height and the size of the woven bagcan be adjusted according to the amount of rice left in the woven bag, so that the rice can be conveniently and rapidly acquired.

Description

technical field [0001] The invention belongs to the technical field of woven bags, in particular to a BOPP film plastic woven bag for food packaging. Background technique [0002] Plastic woven bags are composed of polypropylene bags and polyethylene bags according to the main materials; according to the sewing method, they are divided into seam bottom bags and seam bottom bags; they are currently widely used as a packaging material for fertilizers, chemical products and other items; its main production The process is to use plastic raw materials to extrude film, cut, and unidirectionally stretch into flat wires, and then weave warp and weft to obtain products, which are generally called woven bags. [0003] BOPP film is biaxially oriented polypropylene film. Its production is to make the melt of high molecular polypropylene through a narrow and long head to make a sheet or thick film, and then in a special stretching machine, at a certain temperature and setting Stretching...
