Description

Technical Field

[0001] The utility model relates to the field of packaging materials, in particular to a packaging bag for fresh living things. Background Art

[0002] As one of the most difficult fresh foods to store, how to package hairy crabs has always been a problem for merchants. Patent announcement document CN216425174U discloses a packaging box for storing hairy crabs. However, since this packaging box does not have the ability to absorb and store water, a moist absorbent pad must be placed in the packaging box when this structure is used to ensure that the hairy crabs have a longer survival time in the packaging box. Utility Model Content

[0003] In view of the above problems, the utility model provides a living fresh food packaging bag.

[0004] The technical solution adopted by the utility model is as follows:

[0005] A live fresh food packaging bag, comprising a bag sheet, two bag sheets are matched together to form a bag body, the bag sheet comprises an outer film layer, an inner film layer and a water-absorbing layer, the outer film layer and the inner film layer are respectively arranged on both sides of the water-absorbing layer, and the inner film layer is located inside the bag body, and the outer film layer is located outside the bag body, the inner film layer is a perforated PE film or a perforated PP film or a non-woven fabric, the water-absorbing layer comprises one or more of embossed paper, dry-laid paper, non-woven fabric, fluff pulp, and a water-absorbing resin, the outer film layer is a PE film or a PP film or a PET film or a nylon film, and the water absorption of the water-absorbing layer is greater than 100g / m 2 .

[0006] In this kind of fresh food packaging bag, the bag body is made of two identical bag sheets, wherein the bag sheet is composited by an outer film layer, an inner film layer and a water-absorbing layer, wherein the water-absorbing layer is located between the outer film layer and the inner film layer, and the inner film layer is located inside the bag body. The inner film layer is a perforated PE film or a perforated PP film or a non-woven fabric, so the inner film layer has good air permeability and water permeability, and the outer film layer has good water-blocking performance because it is a PE film or a PP film or a PET film or a nylon film, and the outer film layer can prevent water from being lost in the bag body. After the hairy crab is put into the bag, since the bags on both sides contain water-absorbing layers, the water on the hairy crab (if the hairy crab is relatively dry, you can spray some water in the bag) can pass through the inner membrane layer and be absorbed by the water-absorbing layer. After the water on the hairy crab is absorbed by the water-absorbing layer, the water can be evenly infiltrated and absorbed everywhere in the water-absorbing layer, so the inner wall of the entire bag can remain relatively moist and free of water accumulation. In this way, after the hairy crab (or other shrimps and crabs) is placed in the bag, the entire hairy crab can be placed in a relatively moist environment without water accumulation, effectively extending the shelf life of the hairy crab. When in use, the hairy crab can be directly placed in the bag without placing absorbent paper or a wet towel in the bag.

[0007] In summary, this packaging bag can be used directly to store hairy crabs, and the hairy crabs are placed in a moist environment without stagnant water, thereby extending the live preservation time of the hairy crabs.

[0008] Optionally, ventilation holes are provided on the bag sheet.

[0009] The purpose of providing the air holes is to ensure that after the bag mouth is closed, the entire bag body still maintains good permeability inside and outside the bag body, ensuring that the hairy crabs in the bag have a longer survival time.

[0010] Optionally, the air holes penetrate the outer film layer, the inner film layer and the water-absorbing layer of the bag sheet.

[0011] Optionally, the air holes penetrate the outer film layer and the water-absorbing layer of the bag sheet.

[0012] Optionally, the diameter of the air holes is 1 mm to 20 mm.

[0013] Optionally, the diameter of the air holes is 5 mm to 10 mm.

[0014] The utility model has the beneficial effects of being able to directly store hairy crabs and placing the hairy crabs in a moist environment without stagnant water, thereby extending the live preservation time of the hairy crabs. BRIEF DESCRIPTION OF THE DRAWINGS

The structure of the bag body can be found in the attached Figure 3 As shown in the figure, the heat-sealed parts 11 at the edges of the two bag sheets 1 are fixed together by heat sealing to form a bag body, and a zipper 2 is arranged on the bag mouth of the bag body. The bag sheet 1 includes an outer film layer 103, an inner film layer 101 and a water-absorbing layer 102. The outer film layer 103 and the inner film layer 101 are respectively arranged on both sides of the water-absorbing layer 102, and the inner film layer 101 is located inside the bag body, and the outer film layer 103 is located outside the bag body. The inner film layer 101 is a perforated PE film or a perforated PP film or a non-woven fabric. The water-absorbing layer 102 includes one or more of embossed paper, dry-laid paper, non-woven fabric, fluff pulp, and water-absorbing resin. The outer film layer 103 is a PE film or a PP film or a PET film or a nylon film. The water absorption of the water-absorbing layer 102 is greater than 100g / m 2 .

[0024] In this fresh food packaging bag, the bag body is made of two identical bag sheets 1, wherein the bag sheet 1 is composited by an outer film layer 103, an inner film layer 101 and a water-absorbing layer 102, wherein the water-absorbing layer 102 is located between the outer film layer 103 and the inner film layer 101, and the inner film layer 101 is located in the bag body. The inner film layer 101 is a perforated PE film or a perforated PP film or a non-woven fabric, so the inner film layer 101 has good air permeability and water permeability, and the outer film layer 103 is a PE film or a PP film or a PET film or a nylon film, so the outer film layer 103 has good water-blocking performance, and the outer film layer 103 can prevent water loss in the bag body. After the hairy crab is put into the bag, since the bag sheets 1 on both sides contain the water-absorbing layer 102, the water on the hairy crab (if the hairy crab is relatively dry, some water can be sprayed in the bag) can pass through the inner membrane layer 101 and be absorbed by the water-absorbing layer 102. After the water on the hairy crab is absorbed by the water-absorbing layer 102, the water can be evenly infiltrated and absorbed everywhere in the water-absorbing layer 102, so the inner wall of the entire bag can be kept relatively moist and without water accumulation. In this way, after the hairy crab (or other shrimps and crabs) are placed in the bag, the entire hairy crab can be placed in a relatively moist environment without water accumulation, effectively extending the storage time of the hairy crab. When in use, the hairy crab can be directly put into the bag without placing absorbent paper or a wet towel in the bag.

[0025] In summary, this type of packaging bag can be used directly to store hairy crabs, and the hairy crabs are placed in a moist environment without stagnant water, thereby extending the live preservation time of the hairy crabs.

[0026] The bag sheet 1 is provided with ventilation holes 104. The ventilation holes 104 are provided to ensure that after the bag mouth of the bag body is closed, the entire bag body still maintains good permeability inside and outside the bag body, ensuring that the hairy crabs in the bag body have a longer survival time.

[0027] The air holes 104 penetrate the outer film layer 103 , the inner film layer 101 and the water-absorbing layer 102 of the bag sheet 1 .

[0028] The diameter of the air pores 104 is 1 mm to 20 mm, and preferably 5 mm to 10 mm.
