Description

Technical Field

[0001] The utility model relates to the technical field of storage bags, in particular to a storage bag with double-pressed edges on the bag body. Background Art

[0002] The main materials of storage bags are generally polyethylene and polypropylene. Storage bags are widely used in food packaging. Non-toxic plastic bags are milky white, translucent or colorless and transparent, flexible, smooth to the touch, and have a waxy surface. Toxic plastic bags are turbid or light yellow in color and feel sticky and astringent. However, formally produced plastic food packaging is safe, but you must also pay attention to the method of use, otherwise it will bring negative effects.

[0003] During actual use, storage bags are often subjected to various external forces, such as squeezing and pulling. These external forces are likely to cause damage or deformation of the storage bag, thus affecting its normal use. Traditional storage bags often fail to achieve a good sealing and sufficient durability in terms of material selection and structural design, and thus fail to meet users' demand for high-quality storage solutions. To address these issues, a storage bag with double-pressed edges is proposed. Utility Model Content

[0004] To address the aforementioned technical issues, a storage bag with double-pressed edges is provided. This technical solution addresses the aforementioned background art issue: during actual use, storage bags are often subjected to various external forces, such as squeezing and pulling.

[0030] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.

[0031] Please refer to Figures 1 to 5 As shown, a storage bag with a double-pressed edge of a bag body includes a bag body 1, which includes two parts, bag body 1 101 and bag body 2 102. Double-pressed edge mechanisms 2 for sealing are hot-pressed on both sides of bag body 101 and bag body 2 102. The double-pressed edge mechanisms 2 not only enhance the sealing performance of bag body 101 and bag body 2 102, but also strengthen the structure of the edge of the bag body 1 through the edge pressing process, so that the bag body 1 is less likely to be damaged when subjected to external forces (such as squeezing, pulling, etc.), which significantly improves the overall durability and service life of the storage bag. The bottoms of bag body 101 and bag body 2 102 are hot-pressed with sealed edges 3, and the double-pressed edge mechanisms 2 and sealed edges 3 on both sides effectively seal the three sides of the bag body 1. A sealing mechanism 4 is provided at the upper opening of the bag body 1, and the sealing mechanism 4 can facilitate the opening and closing of the bag body 1.

[0032] Specifically, the double pressing edge mechanism 2 includes a first pressing edge 201 and a second pressing edge 202. The first pressing edge 201 is hot pressed on the relatively outer sides of bag body 101 and bag body 2 102 along the vertical direction, and the second pressing edge 202 is hot pressed on both sides of bag body 101 and bag body 2 102 along the partial edge direction of bag body 2 102.

[0033] Specifically, the sealing mechanism 4 includes a sealing sub-strip 401, a fixing part 402 and a sealing mother strip 403. The sealing sub-strip 401 is fixedly connected to the upper inner side of the bag body 101. The sealing sub-strip 401 is fixedly connected to the fixing parts 402 on the opposite sides, and the fixing parts 402 are fixedly connected to the inner side of the bag body 101.

[0034] Specifically, the sealing mother strip 403 is installed on the upper inner side of the bag body 2 102. The sealing mother strip 403 is adapted and clamped with the sealing sub-strip 401. By squeezing the sealing sub-strip 401, the sealing sub-strip 401 will enter the corresponding groove of the sealing mother strip 403, so that the upper sides of the bag body 101 and the bag body 2 102 are closed. Therefore, by cooperating with the double edge pressing mechanism 2 and the edge sealing 3 on both sides, the bag body itself 1 forms a closed space. Similarly, by pulling the sealing sub-strip 401 and the sealing mother strip 403 outward, the bag body itself 1 can be opened to complete the storage of items.

[0035] Specifically, the bag body 1 includes a base layer 5, a waterproof layer 6, a pull-resistant layer 7, a wear-resistant layer 8 and resin particles 9, and the base layer 5, the waterproof layer 6, the pull-resistant layer 7, the wear-resistant layer 8 and the resin particles 9 are sequentially bonded by hot melt adhesive.

[0036] Specifically, the base layer 5 is made of polyethylene material with a thickness of about 0.2 mm, is non-toxic and harmless, and has good flexibility and basic structural support.

[0037] Specifically, the waterproof layer 6 is made of polyurethane material and has a thickness of about 0.1 mm, which effectively prevents the interior of the storage bag from being corroded by internal and external moisture and ensures that the moisture inside the storage bag is not exposed.

[0038] Specifically, the pull-resistant layer 7 is made of nylon material with a thickness of about 0.15 mm. Since the nylon material has super tensile strength and cooperates with the double edge pressing mechanism 2, the tensile resistance of the storage bag is undoubtedly ensured.

[0039] Specifically, the wear-resistant layer 8 is made of rubber material and has a thickness of about 0.1 mm. The effective wear-resistant performance of the rubber not only increases the wear resistance of the storage bag, but also further improves the service life of the storage bag.

[0040] Specifically, a plurality of groups of resin particles 9 are linearly distributed on the outer surface of the wear-resistant layer 8 . The resin particles 9 are evenly distributed on the outer surface of the wear-resistant layer 8 , so that the outermost wear-resistant layer 8 not only has a wear-resistant effect, but also improves the anti-slip property of the storage bag.

[0041] The working principle and usage process of this device: the upper side of the storage bag can be quickly opened or closed by the sealing sub-strip 401 and the sealing main strip 403, and the coordinated use of the double-edge pressing mechanism 2 and the edge sealing 3 on both sides not only makes the storage bag less likely to be damaged when subjected to external forces (such as squeezing, pulling, etc.), significantly improving the overall durability and service life of the storage bag, but also effectively improves the waterproofness, tensile strength, wear resistance and anti-slip properties of the storage bag through the base layer 5, waterproof layer 6, pull-resistant layer 7, wear-resistant layer 8 and resin particles 9.

[0042] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions merely illustrate the principles of the present invention. Various changes and improvements are possible without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention. The scope of protection claimed for the present invention is defined by the appended claims and their equivalents.
