Description

Technical Field

[0001] This utility model relates to the field of membrane technology, specifically to a film for food packaging. Background Technology

[0002] Food packaging films are polymer materials used to wrap the surface of food to isolate it from microorganisms, bacteria, and external contaminants, preventing and prolonging food spoilage. Food packaging films mainly include photocatalytic inorganic antibacterial agent films, natural and polymeric antibacterial agent films, composite antibacterial agent films, inorganic antibacterial agent films, and organic antibacterial agent films.

[0003] Currently, existing food packaging films are typically rolled into a tube. When needed, the outermost end of the film is pinched and lifted to the desired length before tearing. The torn film is then placed on the food surface for packaging. However, because static electricity easily accumulates between the films, when they are rolled together, the film surface carries a static charge. This charge causes the layers of the film to attract each other. After tearing off a sheet, the remaining film quickly springs back and adheres tightly to the other layers, making it difficult to peel off. This makes the use of food packaging films inconvenient. Utility Model Content

[0004] The purpose of this invention is to provide a food packaging film to solve the above-mentioned problems.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: a food packaging film, comprising a plurality of film bodies, wherein a pinching strip is provided on one side of each film body, and a connecting strip for adhering to the pinching strip is provided on the other side, the common thickness of the pinching strip and the connecting strip is equal to the thickness of the film body, a crease is provided between adjacent film bodies, and a plurality of tear teeth are provided between the pinching strip and the film body on the side facing the crease, the tear teeth being evenly distributed along the length of the crease.

[0006] As a further feature of this invention, the gripping band includes an isolation pad made of rubber material.

[0007] As a further feature of this invention, the tear teeth include a through groove, and both ends of the through groove are provided with easy-tear openings, which are triangular in shape.

[0008] As a further feature of this invention, the membrane body includes a first base layer and a second base layer, and a reinforcing layer is provided between the first base layer and the second base layer, the reinforcing layer being made of EVA material.

[0009] As a further feature of this invention, the first base layer is made of PVC material.

[0010] As a further setting of the utility model, the second base layer is made of PE material.

[0011] Compared with the prior art, the utility model has the beneficial effects that:

[0012] The utility model discloses in use, can tear along the length direction of the crease, because the setting of the tear tooth makes the tearing more relaxed and labor saving, can easily tear down a film body, and the connecting band on it is separated from the pinch band on the next film body after the film body is torn down, then the pinch band on the next film body loses the supplement of the connecting band, will form a gap with the film surface, cannot be closely attached to the film surface, then when tearing the next film, only need to insert the nail into the gap, then pinch the pinch band and exert force, can easily peel off the film body, through this setting, the use of food packaging film is more convenient and simple.

[0019] The technical scheme in the embodiments of the utility model will be apparently and completely described below in conjunction with the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor fall within the protection scope of the utility model.

[0020] Please refer to Figures 1-3As shown in the figure, a food packaging film includes a plurality of film bodies 1, a pinch belt 2 is arranged on one side of the film body 1, a connecting belt 3 for mutual adhesion with the pinch belt 2 is arranged on the other side, the combined thickness of the pinch belt 2 and the connecting belt 3 is equal to the thickness of the film body 1, a crease is arranged between adjacent film bodies 1, and a plurality of tear teeth 4 are arranged between the pinch belt 2 and the film body 1 on the side facing the crease, and the tear teeth 4 are evenly arranged along the length direction of the crease. When the film is used, it can be torn along the length direction of the crease. Due to the arrangement of the tear teeth 4, the tearing is more relaxed and labor-saving, so that a film body 1 can be easily torn off. After the film body 1 is torn off, the connecting belt 3 on it is separated from the pinch belt 2 on the next film body 1, so that the pinch belt 2 on the next film body 1 loses the supplement of the connecting belt 3 and forms a gap with the surface of the film, which cannot be tightly adhered to the surface of the film. Therefore, when the next film needs to be torn, only the nail needs to be clamped into the gap and then the pinch belt 2 needs to be pinched and forced, and the film body 1 can be easily peeled off. Through this arrangement, the use of the food packaging film is more convenient and simple. The pinch belt 2 includes a separation pad 5 made of rubber material, which will not be adsorbed to the surface of the film. Through the separation of the separation pad 5, the adhesion between the lower surface of the pinch belt 2 and the surface of the film can be avoided, so that the gap between the pinch belt 2 and the surface of the film is always maintained, facilitating the peeling of the film body 1.

[0021] As shown in the figure, Figure 3 、 Figure 4 As shown in the figure, the tear teeth 4 include a through slot 6, an easy tear opening 7 is arranged at both ends of the through slot 6, the easy tear opening 7 is triangular, and the tip of the easy tear opening 7 faces away from the through slot 6. Due to the existence of the easy tear opening 7, the adjacent tear teeth 4 can be easily torn, so that the operation of tearing off the film body 1 is more relaxed and labor-saving, and the use of the film is more convenient.

[0022] As shown in the figure, Figure 5 As shown in the figure, the film body 1 includes a first base layer 8 and a second base layer 9, a reinforcing layer 10 is arranged between the first base layer 8 and the second base layer 9, and the reinforcing layer 10 is made of EVA material. The EVA material has good flexibility and good strength and tensile resistance, so that the film body 1 has good tensile resistance and high durability. The first base layer 8 is made of PVC material, which is light in quality and high in strength, has good softness, so that the film body 1 has high strength and good softness. The second base layer 9 is made of PE material, which has good flexibility and good elasticity, so as to ensure the elasticity and toughness of the film body 1.

[0023] It is apparent for a person skilled in the art that the present application is not limited to the details of the above-described exemplary embodiments, but that it can be implemented in other concrete forms without departing from the spirit or the essential characteristics of the present application. Therefore, the embodiments should be considered as exemplary and non-limiting, the scope of the present application being defined by the claims appended hereto rather than by the above description, and all the changes which fall within the meaning and the scope of the equivalent elements of the claims are intended to be embraced therein.
