Problems solved by technology
[0003] However, the existing bubble bags are all single-layer, and have been foamed and inflated or expanded during the production process.
Since this kind of bubble bag has been inflated and expanded, the shape and volume are relatively large, so it is not convenient to fold and store or carry around; excessive use will cause increased logistics costs and environmental pollution

Embodiment Construction
[0021] The preferred embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.
[0022] like figure 1 , 2 , 3, 4 and 6, in this embodiment, the inflatable double-layer bubble bag 100 is a plastic material bubble bag with a square structure. The bubble bag 100 includes a surface layer 120 and a bottom layer 110, and a pocket 101 formed by the surface layer 120 and the bottom layer 110; the surface layer 120 and the bottom layer 110 are formed by folding in half, and the folded side 104 is heated by a heat sealer. Seal; at this time, the side between the surface layer 120 and the bottom layer 110 is in a sealed shape.
[0023] In the bubble bag 100, the surface layer 120 includes a first outer layer 123 and a first inner layer 124, and the side at the pocket opening 101 between the two is heat-sealed by a first heat-sealing tape 121; A surface layer air-filled cavity 125 is formed between the first outer laye...

The invention discloses an inflatable double-layered bubble pack. The inflatable double-layered bubble pack comprises a surface layer and a bottom layer with inflating spaces, and a pack opening formed by the surface layer and the bottom layer, wherein the surface layer comprises a first outer layer and a first inner layer; the bottom layer comprises a second outer layer and a second inner layer;an inflation hole is formed in a surface layer inflation cavity or a bottom layer inflation cavity; a plurality of heat seal points are arranged on the bubble pack at intervals, and an airflow channelis formed between the heat seal points and a side edge; the surface layer and the bottom layer are bonded through the heat seal points; and a sealing tape for sealing the pack opening is arranged onthe inner surface in the pack opening. Only when the inflatable double-layered bubble pack is in use, can inflation be performed by use of an air pump through the inflation hole, so that the bubble pack is inflated to expand. Under interaction of the heat seal points, an expanding gas forms bubbles to protect an object in the pack against such external impacts as vibration, collision and extrusion; and as the inflatable double-layered bubble pack is inflated only when in use, the bubble pack is small in size and convenient to fold for storage and carrying.
Description
technical field [0001] The invention relates to the field of bubble bag preparation, in particular to an inflatable double-layer bubble bag. Background technique [0002] With the overall improvement of express logistics, fragile, precise, anti-extrusion, and small electronic items often appear in express logistics business. In order to prevent these items from being damaged due to extrusion, impact or vibration during express delivery, Bubble bags are often used as fillers or protective layers to protect against shocks and impacts. [0003] But existing air bubble bag is all single-layer, and has just foamed and inflated or expanded in the production process. Since this kind of bubble bag has been inflated and expanded, its external volume is relatively large, and it is not convenient to fold and store or carry it around; excessive use will result in increased logistics costs and environmental pollution. Contents of the invention [0004] The problem to be solved by the...
