Abstract

The invention belongs to the technical field of packaging and particularly relates to a kraft bag. The kraft bag comprises a kraft bag body, partition boards, plastic ring racks and a sealing device. The partition bags are arranged at the center of the kraft bag body in an intersecting manner. The inner portion of the kraft bag body is divided into four parts through the partition boards. The sealing device is arranged on the opening portion of the kraft bag body. The plastic ring racks are arranged outside the kraft bag body at equal intervals. The sealing device comprises a first sealing board and a second sealing board. The first sealing board and the second sealing board are identical in shape and in bilateral symmetry. The first sealing board and the second sealing board are connected through a rotating shaft. The first sealing board is provided with a rubber sealing strip. The second sealing board is provided with a sealing slot. The first sealing board is provided with a pull ring. Through cooperation between the sealing device and the plastic ring racks, the kraft bag is convenient to fold, the capacity of the kraft bag is increased after the packaging bag is unfolded, and the kraft bag is firmer and not prone to damage. Through the partition boards, multiple kinds of objects are placed in the kraft bag conveniently. The rubber sealing strip arranged on the sealing device enables the kraft bag to be good in overall seal performance.

Description

technical field [0001] The invention belongs to the technical field of packaging, in particular to a kraft paper bag. Background technique [0002] In the prior art, packaging bags refer to bags used for packaging various supplies, so that the goods are conveniently transported and stored during the production and distribution process. Widely used in daily life and industrial production. Actual figures show that 80% of used plastic bags are eventually transported to landfills for disposal like general garbage, and only 7% of plastics are recycled. Therefore, it is necessary to use paper packaging bags, but the paper packaging bags on the market are simple in structure and are just paper bags, which have poor airtightness and basically do not have airtightness after opening, and simply fold the packaging bag when not in use, so Very easy to break. Contents of the invention [0003] The problem to be solved by the present invention is to provide a kraft paper bag, which i...
