Description

Technical Field

[0001] The utility model belongs to the technical field of degradable plastic bags, in particular to a degradable printed bag. Background Art

[0002] Degradable plastic bags are now widely used. Supermarket shopping bags, roll-up fresh-keeping bags, ground films, etc. are all large-scale applications in China. Among them, the use of PLA (polylactic acid) and starch-based biodegradable plastic bags to replace traditional plastic bags can effectively alleviate white pollution and have a very good effect on environmental governance.

[0003] Most of the current biodegradable printed bags are single-layer structures, which make them low in strength, small in load capacity, and very inconvenient to use. In addition, the existing printed bags cannot separate items. When carrying fragile items, other items will squeeze the fragile items and cause damage, which is not conducive to use. Utility Model Content

[0004] The utility model aims to provide a degradable printing bag to solve the technical problems raised in the background technology.

[0005] To achieve the above-mentioned purpose, the specific technical scheme of the utility model is as follows: a degradable printed bag, comprising an outer bag and an inner bag located in the inner cavity of the outer bag, a foldable dividing strip is provided at one end of the inner cavity of the inner bag, two groups of symmetrically distributed handle straps are provided on the outer bag, and the bottom of the handle straps is supported on the bottom of the outer bag.

[0006] Preferably, the outer bag and the inner bag are connected by heat sealing.

[0007] Preferably, the top end of the inner bag is higher than the top end of the outer bag.

[0008] Preferably, the dividing strip comprises two symmetrically distributed first folded strips, one end of the two first folded strips is fixedly connected to the inner wall of the inner bag, the other end of the two first folded strips is folded and connected to the second folded strip, and one end of the two second folded strips away from the first folded strips is fixedly connected to a flat pull strip.

[0009] Preferably, the heights of the first folding belt, the second folding belt and the flat draw belt are equal to the height of the inner bag.

[0010] Preferably, the handle strap includes a fixing strap, the fixing strap is in a U-shaped structure, and the top ends of the two vertical sections of the fixing strap are respectively provided with a first lifting strap and a second lifting strap, and the first lifting strap and the second lifting strap are fixedly connected by snaps.

[0011] Preferably, two groups of mounting grooves corresponding to the fixing belts are arranged in the outer bag, the mounting grooves are U-shaped structures, and the size of the fixing belts matches the size of the mounting grooves.

[0012] Preferably, the front and back sides of the outer bag are printed with words or pictures, and the outer bag and the inner bag are both made of polyhydroxyalkanoate or starch-based plastic.

[0013] The utility model has the following advantages:

[0014] 1. The utility model sets the top of the inner bag higher than the top of the outer bag, so that it is convenient to take out and put articles in the inner bag, and the double-layer bag effectively prevents the phenomenon of articles being scattered due to the weak strength of one bag, and improves the moisture-proof performance.

[0015] 2. Through the setting of the dividing belt, when you need to carry fragile items, you can pull the dividing belt open and place the fragile items in the cavity formed between the dividing belt and the inner bag. This can effectively separate the fragile items from other items to avoid the fragile items being squeezed by other items and causing damage. When there is no need to isolate the items, the dividing belt can be folded and fit with the inner wall of the inner bag, which will not take up space and is highly practical.

[0016] 3. The fixing belt, the first lifting belt and the second lifting belt are an integrated structure, and when the fixing belt is installed on the mounting groove, the horizontal section of the fixing belt will be at the bottom of the outer bag, and the two vertical sections of the fixing belt will be at the two vertical surfaces of the outer bag, thereby having a good bottoming effect on the outer bag and greatly improving the load-bearing effect of the printed bag.
