Clamping chain intercommunication type packaging bag and using method

Abstract

The invention discloses a clamping chain intercommunication type packaging bag and a using method. A packaging bag body comprises a clamping chain, the clamping chain divides the packaging bag body into at least one storage chamber, the storage chambers comprise the first storage chamber and the second storage chamber, the clamping chain is arranged between the first storage chamber and the second storage chamber. Fluid substances are contained in the first storage chamber, solid substances or solid substances attached with fluid are contained in the second storage chamber, the whole clamping chain is a stress point for applying external force, and a user applies the external force to the fluid substances in the first storage chamber in the direction of the clamping chain; and the clamping chain is opened due to stress to enable the fluid substances in the first storage chamber to flow into the second storage chamber to be mixed, double-cavity or multi-cavity communication is achieved in a clamping chain mode, and the situation that liquid or air leaks from the bag body due to accidental external force is avoided.

Description

technical field [0001] The invention relates to the technical field of zipper-type packaging bags, in particular to a zipper-chain intercommunicating packaging bag and a usage method. Background technique [0002] Packaging bags are mainly used to pack various items, so that the items are conveniently transported and stored during the production and circulation process, and are widely used in daily life and industrial production. [0003] Generally, each packaging bag corresponds to a chamber. To achieve multi-chamber isolation on a packaging bag, it is necessary to rely on a mold for heat sealing and isolation during the bag making process. In this way, during the bag making process: in addition to In addition to satisfying the high heat-sealing strength of each sealing edge of the packaging bag, it is also necessary to consider that the heat-sealing strength of the isolation edge between the chambers is moderate, and it is also necessary to ensure that the liquid or items ...

Problems solved by technology

[0003] Generally, each packaging bag corresponds to a chamber. To achieve multi-chamber isolation on a packaging bag, it is necessary to rely on a mold for heat sealing and isolation during the bag making process. In this way, during the bag making process: in addition to In addition to satisfying the high heat-sealing strength of each sealing edge of the packaging bag, it is also necessary to consider that the heat-sealing strength of the isolation edge between the chambers is moderate, and it is also necessary to ensure that the liquid or items in the packaging are not leaking. It is not easy to be squeezed out and penetrate the cavity. Since the entire packaging bag is made of the same material structure, the heat seal strength of each side seal and the heat seal strength of the isolation belt will not form a large difference. Under the condition that the isolation belt is easy to penetrate , because the heat sealing strength of each side seal will not be high, there will be a large quality risk hidden danger in the production process of the packaging bag, resulting in the packaging bag being prone to liquid, air, and object leakage

[0004] Therefore, there is an urgent need to develop a packaging bag with a middle isolation belt that is not high in strength and is easy to penetrate, but each head seal and side seal have relatively high heat-sealing strength. Quality problems of bag leakage and air leakage
