[0002] Packaging bags are a kind of packaging design. They are used for food packaging in life and play a role in preservation and storage. Food packaging bags refer to film containers that are in direct contact with food and are used to hold and protect food. Food packaging bags can be divided into ordinary food packaging bags, vacuum food packaging bags, inflated food packaging bags, boiled food packaging bags, steamed food packaging bags and functional food packaging bags according to their application range.

[0003] Most packaging bags on the market today require sharp tools such as knives or scissors to open when the packaged items inside need to be taken out. Some packaging bags that are easy to tear cannot be opened regularly along a specific route when torn. The gaps in the torn packaging bags extend irregularly and easily extend to other directions, which can easily cause the items or liquids in the packaging bags to spill, causing waste.

[0004] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content

The diamond-shaped easy-tear opening makes it easier for the user to tear along the middle of the thickened layer one and the thickened layer two, further providing convenience for the user when tearing the bag.

[0009] The utility model is further configured as follows: the front and back sides of the packaging bag body are both fixedly connected with an auxiliary tear strip 1, and the front and back sides of the packaging bag body are both fixedly connected with an auxiliary tear strip 2.

[0010] By adopting the above technical solution, the auxiliary tear strip 1 is located below the thickened layer 1 and corresponds to the diamond-shaped easy-tear opening, and the auxiliary tear strip 2 is located above the thickened layer 2 and corresponds to the diamond-shaped easy-tear opening.

[0011] The utility model is further configured as follows: the packaging bag body is adhered with three layers of films, which are an aluminum foil film layer, a BOPTE film layer and a polyethylene film layer.

[0012] By adopting the above technical solution, the outer layer of the packaging bag body is adhered to the BOPTE film layer, and the polyethylene film layer is the innermost layer of the packaging bag body.

[0013] The utility model is further configured as follows: the polyethylene film layer is adhered to the aluminum foil film layer by a polyurethane adhesive, and the aluminum foil film layer is adhered to the BOPTE film layer by a polyurethane adhesive.

[0014] By adopting the above technical solution, the structure of the packaging bag body is, from outside to inside, the packaging bag outer layer, the BOPTE film layer, the aluminum foil film layer and the polyethylene film layer, which are bonded together by polyurethane adhesive.

[0015] The utility model is further configured as follows: the thickness of the polyethylene film layer is in the range of 12-24 μm, the thickness of the aluminum foil film layer is in the range of 6-10 μm, and the thickness of the BOPTE film layer is in the range of 15-30 μm.

[0016] By adopting the above technical solution, the thickness of the polyethylene film layer is 12 μm, the thickness of the aluminum foil film layer is 6 μm, and the thickness of the BOPTE film layer is 15 μm.

[0017] The beneficial effects of the utility model are:

[0018] 1. The utility model is provided with a diamond-shaped easy-tear opening, and the user can tear the packaging bag by pinching the auxiliary tear strips 1 and 2 along the diamond-shaped easy-tear opening between the thickened layer 1 and 2, which makes the operation more convenient, and the torn packaging opening is flat and beautiful, and the torn opening does not cut the hands and mouth. The provision of the auxiliary tear strips 1 and 2 makes it easier for the user to pinch the auxiliary tear strips on the packaging bag, further making it more convenient to tear the opening;

[0019] 2. The utility model is provided with a plurality of layers of film, and the structure of the packaging bag is, from the outside to the inside, an outer layer of the packaging bag, a BOPTE film layer, an aluminum foil film layer and a polyethylene film layer, which are bonded together by a polyurethane adhesive. The composite of the multi-layer film makes the packaging bag have the properties of high strength, good sealing, high barrier properties and easy tearing, making the tearing edge smoother, and preventing the items from being scattered when being torn.

[0025] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the present invention is further described below in conjunction with specific illustrations.

[0026] like Figure 1-Figure 4 As shown, a packaging bag that is easy to tear includes a packaging bag main body 1, and the packaging bag main body 1 is adhered with three layers of film, namely an aluminum foil film layer 10, a BOPTE film layer 11 and a polyethylene film layer 9. The outer layer of the packaging bag main body 1 is adhered to the BOPTE film layer 11, and the polyethylene film layer 9 is the innermost layer of the packaging bag main body 1. The polyethylene film layer 9 is adhered to the aluminum foil film layer 10 through a polyurethane adhesive, and the aluminum foil film layer 10 is adhered to the BOPTE film layer 11 through a polyurethane adhesive. The structure of the packaging bag main body 1 is, from the outside to the inside, the packaging bag outer layer, the BOPTE film layer 11, the aluminum foil film layer 10 and the polyethylene film layer 9, which are adhered together through a polyurethane adhesive.

[0027] The thickness of the polyethylene film layer 9 is in the range of 12-24 μm, the thickness of the aluminum foil film layer 10 is in the range of 6-10 μm, and the thickness of the BOPTE film layer 11 is in the range of 15-30 μm, wherein the thickness of the polyethylene film layer 9 is 12 μm, the thickness of the aluminum foil film layer 10 is 6 μm, and the thickness of the BOPTE film layer 11 is 15 μm.

[0028] A sealing edge 2 is fixedly connected to the top of the packaging bag body 1, a thickening layer 1 3 is fixedly installed on the front and back of the packaging bag body 1, a thickening layer 2 4 is fixedly installed on the front and back of the packaging bag body 1, and a diamond-shaped easy-tear opening 5 is provided between each thickening layer 1 3 and thickening layer 2 4.

[0029] Auxiliary tear strip 1 6 is fixedly connected to the front and back of the packaging bag body 1, and auxiliary tear strip 2 7 is fixedly connected to the front and back of the packaging bag body 1. Auxiliary tear strip 1 6 is located below the thickened layer 1 3 and corresponds to the diamond-shaped easy-tear opening 5. Auxiliary tear strip 2 7 is located above the thickened layer 2 4 and corresponds to the diamond-shaped easy-tear opening 5.

[0030] A handle opening 8 is provided inside the sealing edge 2, and a diamond-shaped tear-away opening 5 is located in the middle of the thickened layer. The diamond-shaped tear-away opening 5 makes it easier for the user to tear the bag in the middle of the thickened layer 1 3 and the thickened layer 2 4, further providing convenience for the user when tearing the bag.

[0031] The implementation principle of the utility model is as follows: the structure of the packaging bag is, from outside to inside, the outer layer of the packaging bag, the BOPTE film layer 11, the aluminum foil film layer 10 and the polyethylene film layer 9, which are bonded together by a polyurethane adhesive. The composite of the multi-layer film makes the packaging bag have the properties of high strength, good sealing, high barrier property and easy tearing. When tearing the opening, the user pinches the auxiliary tear strip 1 6 and the auxiliary tear strip 2 7 to tear the packaging bag along the diamond-shaped easy-tear opening 5 between the thickening layer 1 3 and the thickening layer 2 4. The operation is more convenient, and the torn packaging opening is smooth and beautiful.
