Description

Technical Field

[0001] The utility model belongs to the technical field of packaging bags, and particularly relates to a degradable, waterproof and moisture-proof paper-plastic composite bag. Background Art

[0002] Packaging bags are used to hold and seal food, medicine, decorations, daily necessities and other items. Packaging bags can be divided into plastic packaging bags and paper packaging bags according to their materials. When taking out items from a packaging bag, you need to tear the packaging bag open by hand or cut it open with scissors. Since scissors are not convenient to carry with you, many packaging bags have tear-off notches on the edge of the packaging bag for easy opening.

[0003] In the prior art, the tear opening is usually a V-shaped notch. When the packaging bag is torn open along the tear opening, improper operation may easily lead to excessive tearing, causing the items in the packaging bag to spill, such as snacks. Especially for some relatively sturdy plastic bags, it is inconvenient to control the force, and thus it is difficult to control the opening size. Utility Model Content

[0004] The purpose of the utility model is to provide a biodegradable, waterproof and moisture-proof paper-plastic composite bag in response to the above-mentioned technical problems. By tearing any one of the first tear opening and the second tear opening, an opening can be torn out of the packaging bag body to take out the items. The first tear stop strip limits the size of the tear opening to avoid excessive tearing. By tearing the third tear opening, the opening can be torn to the maximum. The first tear opening, the second tear opening and the third tear opening can be selected according to needs to tear the packaging bag body.

[0005] In view of this, the utility model provides a degradable waterproof and moisture-proof paper-plastic composite bag, comprising:

[0032] Embodiment 1:

[0033] This embodiment provides a degradable waterproof and moisture-proof paper-plastic composite bag, comprising:

[0034] The packaging bag body 1 comprises two packaging surfaces 11 connected to each other, and a receiving cavity is formed between the two packaging surfaces 11;

[0035] The first flange 2 is arranged on one side of the X axis of the packaging bag body 1, and a first tearing opening 7 is arranged at the top of the first flange 2;

[0036] The second flange 3 is arranged on the other side of the packaging bag body 1X axis, and a second tearing opening 8 is arranged at the top of the second flange 3;

[0037] Two first crack-stopping strips 4 are respectively arranged on the two packaging surfaces 11, and the first crack-stopping strips 4 are arranged along the Y-axis direction of the packaging surface 11;

[0038] Two second crack-stopping strips 5 are respectively arranged on two packaging surfaces 11, and the second crack-stopping strips 5 are arranged along the X-axis direction of the packaging surface 11, the first crack-stopping strip 4 intersects with the second crack-stopping strip 5, and the first tearing opening 7 and the second tearing opening 8 are located above the second crack-stopping strip 5;

[0039] The first flange 2 and the second flange 3 are both provided with a third tearing opening 9 , and the third tearing opening 9 is located below the second crack-stopping strip 5 .

[0040] In the present technical solution, the packaging bag body 1 can be made of plastic material, such as polypropylene and polyethylene, which is non-toxic and tasteless, and has waterproof and dustproof effects. The two packaging surfaces 11 of the packaging bag body 1 can be rectangular, and the edges of the two packaging surfaces 11 are connected to each other to form a receiving cavity, a first flange 2 and a second flange 3. The receiving cavity is used to store various articles or foods.

[0041] The first tear opening 7 is opposite to the second tear opening 8 , the first tear opening 7 is located on the outer edge of the first flange 2 , the second tear opening 8 is located on the outer edge of the second flange 3 , and the two third tear openings 9 are located on the outer edges of the first flange 2 and the second flange 3 , respectively.

[0042] The first tear opening 7, the second tear opening 8 and the third tear opening 9 can be V-shaped incisions with sharp angles, or I-shaped incisions and U-shaped incisions. The first tear opening 7, the second tear opening 8 and the third tear opening 9 are convenient for manually tearing the packaging bag body 1, without using tools to open the packaging bag body 1, such as using scissors to open the packaging bag body 1.

[0043] The first crack-stopping strip 4 and the second crack-stopping strip 5 may be strip-shaped film structures, and may be adhered to the outer surface of the packaging surface 11 of the packaging bag body 1 using an adhesive. The first crack-stopping strip 4 and the second crack-stopping strip 5 may be made of plastic materials, such as polyethylene and polypropylene.

[0044] The first crack-stopping strip 4 can be vertically attached to the outer surface of the packaging surface 11, with the top of the first crack-stopping strip 4 extending to the top of the packaging bag body 1, and the bottom intersecting with the second crack-stopping strip 5. The second crack-stopping strip 5 can be horizontally attached to the outer surface of the packaging surface 11, with the two ends of the second crack-stopping strip 5 extending to the first flange 2 and the second flange 3 respectively, so that the first crack-stopping strip 4 and the second crack-stopping strip 5 are perpendicular to each other.

[0045] The articles are loaded into the accommodating cavity from the top of the packaging bag body 1, and then the top of the packaging bag body 1 is heat-sealed. When the articles in the packaging bag body 1 need to be taken out, one of the first tear opening 7, the second tear opening 8 and the two third tear openings 9 is selected according to the needs to tear the packaging bag body 1 open.

[0046] When the packaging bag body 1 needs to be tilted to pour out the contents, the amount of the contents to be taken out needs to be controlled, and either the first tear opening 7 or the second tear opening 8 can be selected for tearing. The packaging bag body 1 is limited by the two first tear-stop strips 4, and the tearing stops at the first tear-stop strips 4 at most, thereby controlling the size of the opening and avoiding accidental tearing. The second tear-stop strip 5 is used to prevent the opening from tilting downward when the packaging bag body 1 is torn.

[0047] The third tear opening 9 is located below the second crack stop strip 5. When the items in the packaging bag body 1 need to be reached in and taken out by hand, for example, if the packaging bag body 1 contains snacks, the opening of the packaging bag body 1 needs to be torn to the maximum. Any one of the two third tear openings 9 can be selected for tearing, and the top of the packaging bag body 1 is completely torn off. At this time, the opening is in the maximum state, which is convenient for reaching in and taking out items.

[0048] In this embodiment, the first tearing opening 7 , the second tearing opening 8 and the third tearing opening 9 can be selected to tear the packaging bag body 1 according to the use requirements.

[0051] The distance L1 between the first crack arresting strip 4 and the first flange 2 is greater than the distance L2 between the first crack arresting strip 4 and the second flange 3 .

[0052] In the present technical solution, when the items in the packaging bag are powder or granular items, such as edible salt, starch and white sugar, it is necessary to tilt the packaging bag body 1 to pour out the powder or granular items inside. At this time, the second tear opening 8 on the second flange 3 can be selected to tear the opening smaller, which is convenient for controlling the amount of items poured out.

[0053] For larger particles, such as candies, etc., the first tear opening 7 on the first flange 2 can be selected to tear the opening larger so that the items can be poured out smoothly.
