Description

Technical Field

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

[0002] At present, fresh food packaging is generally carried out using a packaging film (or packaging bag) dedicated to fresh food to extend the shelf life of the fresh food. The commonly used fresh food packaging film is shown in the patent document announcement number CN208979478U. Since the fresh food packaging film with this structure cannot discharge water droplets (or water beads) generated during the storage of fresh food, the shelf life of the packaging film with this structure is very short when packaging fresh food, because the water droplets will accelerate the decay of the fresh food. Utility Model Content

[0003] Aiming at the above problems, the utility model provides a fresh food packaging bag.

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

[0005] A fresh food packaging bag comprises a first bag sheet and a second bag sheet, wherein the first bag sheet and the second bag sheet cooperate to form a bag body, the bag body is provided with a bag opening, the second bag sheet is paper or dry-laid paper or non-woven fabric, and the second bag sheet contains SAP or SAF.

[0006] When in use, the first bag sheet is located at the top and the second bag sheet is located at the bottom. The second bag sheet is paper, dry paper or non-woven fabric, and contains SAP (super absorbent resin material) or SAF (super absorbent fiber) inside, so the entire second bag sheet has good water absorption performance. Water droplets or water droplets attached to the fresh food can be absorbed by the second bag sheet, ensuring that the fresh food is in a dry environment and extending the shelf life of the fresh food.

[0007] The second bag sheet includes an inner film layer, an outer film layer and a functional layer, which are composited together. The inner film layer is located inside the bag body, the outer film layer is located outside the bag body, the functional layer is located between the inner film layer and the outer film layer, the inner film layer is provided with water absorption holes, the functional layer contains SAP or SAF, and the functional layer is dry-laid paper or paper or non-woven fabric.

[0008] As an improved solution, the second bag sheet is further optimized on the basis of the original functional layer, and an inner film layer and an outer film layer are respectively arranged on both sides. When this packaging bag is used, the first bag sheet is located at the top and the second bag sheet is located at the bottom. The fresh food is placed in the bag body, and the fresh food is pressed against the inner film layer of the second bag sheet. Since the inner film layer is provided with water absorption holes and the functional layer is filled with SAP (super absorbent resin material) or SAF (super absorbent fiber) with good water absorption, the water droplets dripping on the fresh food will pass through the water absorption holes and will be absorbed by the SAP or SAF in the functional layer, so that the fresh food is in a dry environment, ensuring that the fresh food has a longer storage period.

[0009] In summary, the packaging bag can absorb water droplets from fresh produce, so that the fresh produce can be stored in a dry environment, ensuring that the fresh produce has a longer shelf life.

[0010] Optionally, the functional layer is air-laid paper or paper or non-woven fabric.

[0011] Optionally, the water absorption of the functional layer is greater than 50 g / m 2 .

[0012] Optionally, the water absorption of the functional layer is 100 g / m 2 -5000g / m 2 .

[0013] Optionally, the inner film layer is a PE film or a PP film or paper or a non-woven fabric.

[0014] Optionally, the outer film layer is a PE film or a PP film or paper or a non-woven fabric.

[0015] Optionally, an anti-fog coating is provided on the first bag sheet, and the anti-fog coating is located inside the bag body.

[0016] The anti-fog coating is to prevent fogging on the first bag sheet. The anti-fog coating can be achieved by adding an anti-fog agent to the heat-sealing layer resin, or by coating the heat-sealing layer with an anti-fog liquid. The first bag sheet can be one of PP, PE, PET, ONY and other materials, or a composite film of PP, PE, PET, ONY and other materials. The first bag sheet can be with or without air holes.

[0017] Optionally, the diameter of the water absorption hole is 0.1-10 mm.

[0018] The beneficial effect of the utility model is that it can absorb water drops dropped from fresh food, so that the fresh food can be stored in a dry environment, ensuring that the fresh food has a longer storage time. BRIEF DESCRIPTION OF THE DRAWINGS
