Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of packaging bags, and specifically relates to an easily tearable packaging bag. Background Art
[0002] With the continuous improvement of consumers' requirements for the convenience and safety of food and other consumer goods, packaging technology is also constantly developing to meet these needs. Traditional packaging bags usually use simple heat sealing or bonding methods to close the opening, but there are some deficiencies in actual use.
[0003] Firstly, traditional packaging bags often require the assistance of scissors or other tools when opening, which not only increases the inconvenience of use but also may pose safety hazards. Especially when there are no suitable tools, consumers may open the package by force, resulting in damage or scattering of the contents of the package.
[0004] Secondly, many packaging bags lack an effective resealing function after being opened. Once torn, the packaging bag cannot be resealed, which is not conducive to the preservation of unused products. The product is exposed to the air, easily gets damp and deteriorates, shortening the shelf life of the product. This is especially disadvantageous for products that need to be taken multiple times.
[0005] In order to solve the above technical problems, the present application provides a new type of easily tearable packaging bag. Content of the Utility Model
[0006] Aiming at the deficiencies in the background art, the utility model provides an easily tearable packaging bag.
[0007] The technical solution adopted by the utility model is: an easily tearable packaging bag, including a bag body, the bag body is sealed and packaged by a front surface, a rear surface, side surfaces and a bottom surface, the top of the bag body has an opening, a sealing paper film is arranged inside the bag body below the opening, an easily tearable strip is arranged in the middle of the sealing paper film, and a sealing structure is arranged on the front surface and the rear surface above the sealing paper film;
[0008] The sealing structure includes an upper sealing strip, a lower sealing strip and an elastic pressing surface arranged between the upper sealing strip and the lower sealing strip. Both the upper sealing strip and the lower sealing strip include a pressed block arranged on the front surface and a pressing block arranged on the rear surface. An embedding groove is arranged on the pressed block, and an engaging strip that is engaged with the above embedding groove is arranged on the pressing block.
[0009] Further, a plurality of corrugated surfaces are evenly distributed on the surface of the elastic pressing surface.
[0010] Further, the elastic pressing surface is made of food-grade elastic rubber.
[0011] Further, a layer of plant fiber layer is arranged on the inner wall of the bag body.
[0012] Further, the thickness of the plant fiber layer is 0.5 - 1 mm.
[0013] Further, the plant fiber layer is a bamboo fiber layer or sugarcane fiber.
[0014] Further, a layer of polypropylene film is provided on the outer wall of the bag body, and its thickness is 10 - 30 μm.
[0015] The beneficial effects of the present utility model are as follows: 1. Easy to open: By providing a tear strip in the middle of the sealed paper film, users can easily open the package along the preset tear line without using scissors or other tools. This not only improves the convenience of use but also reduces the risk of product damage caused by violent opening.
[0016] 2. Reliable sealing performance: The sealing structure includes an upper seal, a lower seal, and an elastic pressing surface. This design ensures good sealing performance of the packaging bag in the unopened state, effectively preventing air, moisture, and pollutants from entering, thereby extending the shelf life of the product.
[0017] 3. Re - sealable: The sealing structure of this application allows users to re - seal the package after opening. By closely fitting the engaging strip with the installation groove, users can conveniently re - close the packaging bag to maintain the freshness and hygiene conditions of the product, which is especially suitable for products that need to be taken in portions.
[0018] In addition to the purposes, features, and advantages described above, the present utility model has other purposes, features, and advantages. The following will refer to the accompanying drawings to further describe the present utility model in detail. Description of the Drawings
