Description

Technical Field

[0001] This utility model relates to the field of packaging bag technology, specifically a tear-resistant packaging bag with tear lines. Background Technology

[0002] Packaging bags are bags used to package various products, making it convenient to transport and store goods during the production and distribution process. 80% of used plastic bags are eventually transported to landfills for disposal, just like ordinary garbage, and only 7% of plastic is recycled.

[0003] Existing patent document CN214241978U discloses a waterproof packaging bag with a vent at the top. It includes a bag body composed of an upper bottom, a bag body, and a lower bottom. A feed sleeve is provided inside the upper bottom, and these parts are bonded together. The bag body is folded from at least one inner kraft paper layer, one PE film intermediate layer, and at least one outer waterproof kraft paper layer. The upper and lower ends of the PE film intermediate layer are connected to the adjacent inner and outer waterproof kraft paper layers by adhesive dots. An upper connecting outer layer is provided on the outer side of the upper bottom, and a lower connecting outer layer is provided on the outer side of the lower bottom. A vent is provided on the upper connecting outer layer, and the vent communicates with the upper folded edge of the upper bottom. The outer end of the feed sleeve is flush with the side edge of the upper bottom of the bag body, and the vent is located in the middle of the length direction of the upper connecting outer layer. The vent is a long, single cut opening. After the bag is filled, the vent is sealed with paper. The overall structure is well-designed. The bag body is folded from an inner kraft paper layer, a PE film intermediate layer, and an outer waterproof kraft paper layer. The outer waterproof kraft paper layer provides waterproofing for a period of time. In case of emergencies, the contents of the bag can be quickly transferred to prevent damage. A feeding cuff is provided inside the top bottom for easy feeding. An vent is located on the upper connecting outer layer, which is connected to the upper folded edge of the top bottom. This means the vent is connected to the venting channels of the inner kraft paper layer, the PE film intermediate layer, and the outer waterproof kraft paper layer. The upper and lower ends of the PE film intermediate layer are connected to the adjacent inner and outer waterproof kraft paper layers by adhesive. Internal gas is quickly discharged from the spaces between the inner kraft paper layer and the PE film intermediate layer, as well as between the PE film intermediate layer and the outer waterproof kraft paper layer, effectively preventing the bag from bulging. This product is reliable and meets actual usage requirements.

[0004] However, in the existing technology CN214241978U patent, the waterproof packaging bag with a vent at the top has poor tear resistance and protective storage capabilities. As a result, in the actual use of the waterproof packaging bag with a vent at the top, it is not possible to prevent the tear-resistant packaging bag from being torn as needed, and it is not convenient to protect and store the packaging bag tube, thus affecting the tear resistance effect of the waterproof packaging bag with a vent at the top.
