Description

Technical Field

[0001] This utility model relates to the field of food packaging film technology, and in particular to a food packaging film with internal compartments. Background Technology

[0002] Food packaging film is a polymer material used to wrap the surface of food, mainly to isolate the entry of microorganisms, bacteria and foreign contaminants, and to prevent and prolong the spoilage of food.

[0003] For snacks that require dipping sauce, the food and dipping sauce should usually be packaged separately to ensure that each package of snacks comes with a matching dipping sauce for the convenience of the buyer.

[0004] However, the existing technology of using snack packaging bags for dipping sauces is inconvenient to open. When opening the bag, the snacks or dipping sauces are easy to fall out, affecting the normal consumption of the consumer. Therefore, a food packaging film with internal separation is designed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to solve the problems existing in the background art mentioned above, and to propose a food packaging film with internal differentiation.

[0006] The technical problem to be solved by this utility model is to provide a food packaging film with internal differentiation, which solves the problem that existing dipping sauce packaging films are inconvenient to open and that snacks and dipping sauces are easy to spill when opening the bag.

[0007] This utility model provides a food packaging film with internal differentiation, including a lower packaging film and an upper packaging film. Food storage cavities are pressed into both the left and right sides of the lower packaging film. The upper packaging film is heat-sealed onto the upper surface of the lower packaging film. Easy-tear strips are integrally formed on both the left and right ends of the upper packaging film.

[0008] Preferably, the width of the lower packaging film is greater than the width of the upper packaging film.

[0009] Preferably, the width of the lower packaging film is greater than the width of the upper packaging film, and both ends of the lower packaging film extend below the left and right sides of the upper packaging film.

[0010] Preferably, the lower packaging film has a first easy-tear dotted line longitudinally arranged in the center, and the upper packaging film has a second easy-tear dotted line longitudinally arranged in the center.

[0011] Preferably, the first easy-tear dotted line is located between the two food storage cavities, and the second easy-tear dotted line is located directly above the first easy-tear dotted line.

[0012] Preferably, the lower packaging film and the upper packaging film are provided with a PE film layer, a heat insulation layer, a protective layer and an aluminum plating layer from the outside to the inside. The non-contact surfaces of the lower packaging film and the upper packaging film are provided with a PE film layer. A heat insulation layer is fixedly disposed on top of the PE film layer. A protective layer is fixedly disposed on top of the heat insulation layer. An aluminum plating layer is fixedly disposed on top of the protective layer.

[0013] Preferably, the heat insulation layer is made of silica aerogel, and the protective layer is made of polypropylene.

[0014] Compared with the prior art, this utility model has at least the following beneficial effects:

[0015] 1. This utility model features an easy-tear strip. When it is necessary to open the packaging bag for consumption, since both ends of the lower packaging film extend below the left and right sides of the upper packaging film, the upper packaging film can be torn off by pinching the end of the lower packaging film with one hand and the easy-tear strip with the other hand, making it convenient for users to open the bag for consumption.

[0016] 2. By incorporating a first and a second easy-tear perforated line, the packaged snacks and dipping sauces can be separated into two separate bags when the user opens the bag. This facilitates the separate opening of the upper packaging film on the snack compartment and the upper packaging film on the dipping sauce compartment, preventing spillage of snacks or dipping sauces when the upper packaging film is torn off.

[0017] 3. This utility model incorporates a heat insulation layer, a protective layer, and an aluminum-plated layer. The heat insulation layer is made of silica aerogel, which has a very low density, typically between 0.003 and 0.35 g / cm³. 3 Between these layers, the porosity can reach over 90%. Due to its unique nanostructure and low density, silica aerogel has excellent thermal insulation properties. The protective layer is made of polypropylene, which has good toughness and rigidity, and high tensile strength, increasing the strength of the packaging film. The aluminum coating ensures the sealing performance of the packaging film, effectively preventing the contents from getting damp, and completely blocking light, ensuring a longer shelf life for the food.

[0024] Example:

[0025] like Figures 1-3 As shown, an embodiment of this utility model provides a food packaging film with internal differentiation, including a lower packaging film 1 and an upper packaging film 2. Food storage cavities 101 are pressed out on both the left and right sides of the lower packaging film 1. The upper packaging film 2 is heat-sealed on the upper surface of the lower packaging film 1. Easy-tear strips 201 are integrally formed on both the left and right ends of the upper packaging film 2.

[0026] In this embodiment, the width of the lower packaging film 1 is greater than the width of the upper packaging film 2.

[0027] In the food packaging process, firstly, two food storage cavities 101 are pressed out on both the left and right sides of the lower packaging film 1. Then, snacks and dipping sauces are placed into the two food storage cavities 101 respectively. Next, the upper packaging film 2 is covered on the lower packaging film 1, so that the upper packaging film 2 seals the two food storage cavities 101 on the lower packaging film 1. Finally, the upper packaging film 2 is covered on the lower packaging film 1 by heat pressing to complete the packaging.

[0028] With the easy-tear strip 201 provided, when it is necessary to open the packaging bag for consumption, since both ends of the lower packaging film 1 extend below the left and right sides of the upper packaging film 2, the upper packaging film 2 can be torn off from the lower packaging film 1 by pinching the end of the lower packaging film 1 with one hand and the easy-tear strip with the other hand, making it convenient for users to open the bag for consumption.

[0029] In this embodiment, the width of the lower packaging film 1 is greater than the width of the upper packaging film 2, and both ends of the lower packaging film 1 extend below the left and right sides of the upper packaging film 2, making it convenient to pinch the ends of the lower packaging film 1 to open the bag.

[0030] In this embodiment, a first easy-tear dotted line 102 is longitudinally arranged in the center of the lower packaging film 1, and a second easy-tear dotted line 202 is longitudinally arranged in the center of the upper packaging film 2.

[0031] In this embodiment, the first easy-tear dotted line 102 is located between the two food storage cavities 101, and the second easy-tear dotted line 202 is located directly above the first easy-tear dotted line 102, so that the packaging film can be divided into two packaging bags by the first easy-tear dotted line 102 and the second easy-tear dotted line 202, preventing snacks or dipping sauces from spilling when the packaging is opened.

[0032] By providing a first easy-tear dotted line 102 and a second easy-tear dotted line 202, when the user opens the bag, the packaged snacks and dipping sauce can be separated into two different packaging bags through the first easy-tear dotted line 102 and the second easy-tear dotted line 202. This makes it convenient to open the upper packaging film 2 on the food storage cavity 101 containing snacks and the upper packaging film 2 on the food storage cavity 101 containing dipping sauce respectively, preventing the snacks or dipping sauce from spilling when the upper packaging film 2 is torn off.

[0033] In this embodiment, the lower packaging film 1 and the upper packaging film 2 are provided with a PE film layer 3, a heat insulation layer 4, a protective layer 5 and an aluminum plating layer 6 from the outside to the inside. The non-contact surfaces of the lower packaging film 1 and the upper packaging film 2 are provided with the PE film layer 3. The heat insulation layer 4 is fixedly disposed on the top of the PE film layer 3. The protective layer 5 is fixedly disposed on the top of the heat insulation layer 4. The aluminum plating layer 6 is fixedly disposed on the top of the protective layer 5.

[0034] In this embodiment, the heat insulation layer 4 is made of silica aerogel, and the protective layer 5 is made of polypropylene.

[0035] The system comprises a heat insulation layer 4, a protective layer 5, and an aluminum-plated layer 6. The heat insulation layer 4 is made of silica aerogel, which has a very low density, typically between 0.003 and 0.35 g / cm³. 3 Between these layers, the porosity can reach over 90%. Due to its unique nanostructure and low density, silica aerogel has excellent thermal insulation properties. The protective layer 5 is made of polypropylene, which has good toughness and rigidity, and high tensile strength, increasing the strength of the packaging film. The aluminum-plated layer 6 ensures the sealing performance of the packaging film, effectively preventing the contents from getting damp, and completely blocking light, ensuring a longer shelf life for the food.

[0036] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these should also be considered within the scope of protection of this utility model. These will not affect the implementation effect of this utility model or the practicality of the patent.
