Description

Technical Field

[0001] This utility model relates to the field of packaging bag technology, specifically a hand-held flame-retardant and moisture-proof food packaging bag. Background Technology

[0002] Food packaging bags are special containers designed specifically to protect food. They not only prevent physical damage, contamination, and environmental factors from affecting food during transportation and storage, but also effectively extend the shelf life of food. By using materials with good barrier properties, such as plastic film, aluminum foil, or composite materials, food packaging bags can block the intrusion of oxygen, moisture, light, and microorganisms, maintaining the freshness and taste of food. Furthermore, modern food packaging bags emphasize user experience and environmental protection, employing easy-to-open and resealable designs, and tending to use biodegradable or easily recyclable materials to reduce the burden on the environment.

[0003] Current food packaging bags on the market have some shortcomings in practical applications. Firstly, most food packaging bags use a ribbed sealing technology to ensure airtightness. While this design provides good tensile strength, ensuring the contents are sealed and protected, it also makes opening difficult, often requiring considerable force from the consumer, which negatively impacts the user experience. Furthermore, when packaging heavy foods, traditional handle designs are prone to breakage due to excessive weight. The existing structure of food bags is also relatively simple and cannot meet various daily usage needs, reducing the overall practicality of the packaging.

[0004] Secondly, existing food packaging bags are not satisfactory in terms of flame retardancy and moisture resistance. If food is placed in packaging with poor moisture resistance and flame retardancy for a long time, it is very easy to become damp and deteriorate. At the same time, the abrasion resistance of food packaging bags is also a problem. In daily use, especially in the bottom area, frequent friction and contact with hard objects can easily lead to wear and tear, further affecting the moisture resistance of food bags.

[0005] Therefore, a portable, flame-retardant, and moisture-proof food packaging bag is needed to improve the above problems. Utility Model Content

[0006] To address the issue that food packaging bags often have a simple structure that fails to meet various daily usage needs and reduces overall practicality, this invention provides a handle-type flame-retardant and moisture-proof food packaging bag.

[0007] To achieve the above objectives, the present invention provides the following technical solutions:

[0008] A portable flame-retardant and moisture-proof food packaging bag includes a bag body, a handle assembly at the port of the bag body, a flame-retardant layer on the outer wall of the bag body, a moisture-proof layer on the inner wall of the bag body, and a bottom pad on the outer wall of the bag body.

[0009] The bottom padding component includes an inner bottom pad layer, which is installed on the outer wall of the bag body. A heat insulation layer is provided on the outer wall of the inner bottom pad layer, and a wear-resistant layer is provided on the outer wall of the heat insulation layer.

[0010] As a preferred embodiment of this utility model, the handle assembly includes an outer shell, which is installed at the port of the bag body.

[0011] As a preferred embodiment of this utility model, a handle groove is provided on the opposite outer wall of the outer shell, and a reinforcing band is provided on one side of the handle groove and on the inner wall of the outer shell.

[0012] As a preferred embodiment of this utility model, plastic keel sealing clips are symmetrically arranged on the other side of the handle groove and on the inner wall of the outer shell, and Velcro is embedded in the outer wall of the plastic keel sealing clips.

[0013] As a preferred embodiment of this utility model, the flame-retardant layer is made of flexible polyolefin flame-retardant material, the moisture-proof layer is made of polyethylene film material, and the bottom pad is located on the bottom outer wall of the bag body.

[0014] As a preferred embodiment of this utility model, the wear-resistant layer is made of soft polyurethane material, the outer shell is a rectangular structure, and the handle groove is provided in two sets, which are respectively located on the opposite outer walls of the outer shell.

[0015] As a preferred embodiment of this utility model, the reinforcing strip is provided in two sets and is located on the inner walls opposite to each other on the outer shell, and the cross-section of the reinforcing strip is an L-shaped structure.

[0016] As a preferred embodiment of this utility model, the plastic keel sealing clip is a double-ribbed keel sealing structure, and the Velcro is located between the double ribs of the plastic keel sealing clip.

[0017] Compared with existing technologies, this utility model enables the selection of a sealing structure for the food bag by setting a handle component in the handle-type flame-retardant and moisture-proof food packaging bag. At the same time, the handle of the food bag has better tensile strength, which enhances the practicality of the food bag. This allows the food bag to select a suitable sealing structure according to the storage time. In addition, a reinforcing strip is set in the inner cavity of the outer shell. When the user picks up the bag by the handle groove, the reinforcing strip strengthens the handle and prevents breakage, further increasing the practicality of the food bag. This solves the problem that the structure of the food bag is relatively simple and cannot meet various daily use needs, thus reducing the overall practicality of the packaging.

[0018] This invention improves the flame-retardant and moisture-proof properties of food packaging bags by incorporating a flame-retardant layer and a moisture-proof layer. The outer wall of the inner bottom pad has a heat-insulating layer that provides insulation. Additionally, the outer wall of the bottom pad has a wear-resistant layer that increases the bag's abrasion resistance when placed in storage, preventing damage that could compromise its moisture-proof performance. This addresses the shortcomings of existing food packaging bags in terms of flame retardancy and moisture-proofing. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0027] Example: See Figure 1-6The illustrated hand-held flame-retardant and moisture-proof food packaging bag includes a bag body 1, a handle assembly 2 at the port of the bag body 1, a flame-retardant layer 3 on the outer wall of the bag body 1, a moisture-proof layer 4 on the inner wall of the bag body 1, and a bottom pad 5 on the outer wall of the bag body 1.

[0028] In this embodiment, specific references Figure 1 , Figure 5 and Figure 6 The bottom pad 5 includes a bottom pad inner layer 51, which is installed on the outer wall of the bag body 1. A heat insulation layer 52 is provided on the outer wall of the bottom pad inner layer 51, and a wear-resistant layer 53 is provided on the outer wall of the heat insulation layer 52.

[0029] In this embodiment, specific references Figure 1 , Figure 2 , Figure 3 and Figure 4 The handle assembly 2 includes an outer shell 201, which is installed at the port of the bag body 1. The outer shell 201 has a rectangular structure. Handle grooves 202 are provided on the opposite outer walls of the outer shell 201. There are two sets of handle grooves 202, which are respectively located on the opposite outer walls of the outer shell 201. A reinforcing band 203 is provided on one side of the handle groove 202 and on the inner wall of the outer shell 201. There are two sets of reinforcing bands 203, which are respectively located on the opposite inner walls of the outer shell 201. The cross-section of the reinforcing band 203 is L-shaped. On the other side of the handle groove 202 and on the inner wall of the outer shell 201, plastic keel sealing clips 204 are symmetrically provided. Velcro 205 is embedded in the outer wall of the plastic keel sealing clip 204. The plastic keel sealing clip 204 has a double keel sealing structure, and the Velcro 205 is located between the double keels of the plastic keel sealing clip 204.

[0030] Among them, the flame retardant layer 3 is made of flexible polyolefin flame retardant material, the moisture-proof layer 4 is made of polyethylene film material, the bottom pad 5 is located on the bottom outer wall of the bag body 1, the bottom pad 5 increases the wear resistance of the bag body 1, and the wear-resistant layer 53 is made of soft polyurethane material.

[0031] This portable flame-retardant and moisture-proof food packaging bag utilizes Velcro 205 between the double-ribbed sealing structures of the plastic ribbed sealing clips 204. When storing food for an extended period, the plastic ribbed sealing clips 204 can be squeezed and slid, causing the opposing plastic ribbed sealing clips 204 within the outer shell 201 to interlock, thus sealing the inner cavity of the bag body 1. When consuming the food, the Velcro 205 can be squeezed to release the seal. The bag body 1 can be sealed by sticking the 5 pieces together. It is also simple and convenient to tear off the Velcro 205 afterwards. The appropriate sealing structure can be selected according to the storage time. At the same time, a reinforcing strip 203 is provided in the inner cavity of the outer shell 201. When the user picks up the bag body 1 by lifting the handle groove 202, the reinforcing strip 203 strengthens the handle and prevents breakage, further increasing the practicality of the food bag. This solves the problem that the structure of the food bag is relatively simple and cannot meet the various daily use needs, thus reducing the overall practicality of the packaging.

[0032] By providing a flame-retardant layer 3 on the outer wall of the bag body 1, the flame-retardant layer 3 of the flexible polyolefin flame-retardant material can provide a better flame-retardant effect for the bag body 1. By providing a moisture-proof layer 4 on the inner wall of the bag body 1, the moisture-proof layer 4 can provide a better moisture-proof effect for the bag body 1. At the same time, a bottom pad 5 is provided on the outer wall of the bottom outer wall of the bag body 1. A heat insulation layer 52 is provided on the outer wall of the inner layer 51 of the bottom pad, which provides heat insulation for the bag body 1. At the same time, a wear-resistant layer 53 is provided on the outer wall of the bottom pad 5. When the food bag is placed, the wear-resistant layer 53 can increase the wear resistance of the food bag, so as to prevent the bag body 1 from being worn and resulting in poor moisture-proof effect. This solves the problem that the existing food packaging bags are not satisfactory in terms of flame retardancy and moisture-proof performance.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
