Description

Technical Field

[0001] This utility model relates to the field of beef slice preservation packaging technology, and in particular to an easy-tear independent packaging structure for preserving cooked beef slices. Background Technology

[0002] Seasoned beef slices are a convenient food product that has undergone pre-treatment such as seasoning and marinating. Their packaging needs to simultaneously meet the requirements of freshness preservation, leak prevention, and easy opening. Traditional packaging has the following problems: single-layer plastic bags lack sufficient sealing, easily leading to moisture loss and oxidation of flavor substances; aluminum foil bags, while offering good barrier properties, are difficult to open and require tools such as scissors; individual packaging lacks a supporting structure and is easily deformed during transportation.

[0003] While existing technologies can achieve easy-tear functionality, their preservation performance is insufficient and cannot meet the long-term storage requirements of prepared beef slices. Therefore, we propose an easy-tear independent packaging structure for the preservation of prepared beef slices. Utility Model Content

[0004] The purpose of this invention is to provide an easy-tear, individual packaging structure for preserving cooked beef slices, thus solving the existing problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A fresh-keeping, easy-tear, individual packaging structure for prepared beef slices includes an outer composite film with a V-shaped easy-tear slit on the top, a heat-sealing line on the outer side, multiple easy-tear slits on the top, and a fresh-keeping inner layer on the inner side.

[0007] As a further improvement to the above solution, the outer composite film includes a biaxially oriented polypropylene film, an aluminum foil composite layer, and a vinyl acetate copolymer film. The aluminum foil composite layer is fixedly connected to one side of the outer composite film, the aluminum foil composite layer is fixedly connected to one side of the biaxially oriented polypropylene film, and the vinyl acetate copolymer film is fixedly connected to one side of the aluminum foil composite layer.

[0008] As a further improvement to the above solution, the preservation inner layer includes an antibacterial polyethylene film, a polyamide barrier layer, and a linear low-density polyethylene film. The polyamide barrier layer is fixedly connected to one side of the antibacterial polyethylene film, and the linear low-density polyethylene film is fixedly connected to one side of the polyamide barrier layer.

[0009] As a further improvement to the above solution, the V-shaped easy-tear cut is V-shaped and the easy-tear cut is laser-cut.

[0010] By adopting the above technical solution, the outer composite film can be torn open by pinching the V-shaped easy-tear cut. The easy-tear cut is laser-cut, which makes the tearing effect better and will not damage the preservation effect of the outer composite film and the inner preservation layer.

[0011] As a further improvement to the above solution, the material of the biaxially oriented polypropylene film is biaxially oriented polypropylene, the material of the aluminum foil composite layer is aluminum foil, and the material of the vinyl acetate copolymer film is vinyl acetate copolymer.

[0012] By adopting the above technical solution, the biaxially oriented polypropylene film on top of the outer composite film provides excellent mechanical strength and puncture resistance, and the surface can be printed with exquisite patterns to enhance product recognition; the aluminum foil composite layer completely blocks oxygen, ultraviolet rays and odors, preventing the beef slices from oxidizing and deteriorating, while enhancing the packaging stiffness and reducing deformation during transportation; the vinyl acetate copolymer film and the inner packaging bag are heat-sealed to form a sealed structure to prevent moisture leakage; it is elastic and adapts to changes in the shape of the beef slices.

[0013] As a further improvement to the above solution, the antibacterial polyethylene film is made of polyethylene, the polyamide barrier layer is made of polyamide, and the linear low-density polyethylene film is made of linear low-density polyethylene.

[0014] By adopting the above technical solutions, the antibacterial polyethylene film directly contacts the beef slices, inhibiting the growth of microorganisms and extending the shelf life; the food-grade material ensures safety; the polyamide barrier layer is a high-barrier material that prevents moisture evaporation and external oxygen intrusion, maintaining the tender texture of the beef slices; the linear low-density polyethylene film provides flexibility and heat-sealing performance, and is tightly bonded to the outer vinyl acetate copolymer film, enhancing the overall structural stability.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This utility model discloses a fresh-keeping, easy-tear, individual packaging structure for prepared beef slices. By pinching the V-shaped easy-tear cut, the outer composite film can be torn open through the cut. The easy-tear cut is laser-cut, which ensures good tearing effect without damaging the freshness preservation effect of the outer composite film and the inner preservation layer. The biaxially oriented polypropylene film on top of the outer composite film provides excellent mechanical strength and puncture resistance. The surface can be printed with exquisite patterns to enhance product recognition. The aluminum foil composite layer completely blocks oxygen, ultraviolet rays, and odors, preventing the beef slices from oxidizing and spoiling.

[0017] This utility model discloses a fresh-keeping, easy-tear, independent packaging structure for prepared beef slices. Through the W-component, a vinyl acetate copolymer film and an inner packaging bag are heat-sealed to form a sealed structure, preventing moisture leakage. It is elastic, adapting to changes in the shape of the beef slices. An antibacterial polyethylene film directly contacts the beef slices, inhibiting microbial growth and extending shelf life. Food-grade materials ensure safety. A high-barrier polyamide barrier layer prevents moisture evaporation and external oxygen intrusion, maintaining the tender texture of the beef slices. A linear low-density polyethylene film provides flexibility and heat-sealing performance, adhering tightly to the outer vinyl acetate copolymer film to enhance overall structural stability.
