Detailed Description of the Invention

[0019] In order to further explain the technical solution of the present utility model, the following is elaborated in detail through specific embodiments.

[0020] As Figure 1 shown, the present utility model provides a moisture-proof dispensing bag for prefabricated food, including a dispensing bag body 1. The bottom end surface of the dispensing bag body 1 is provided with an integrally formed support plane 2, and the support plane 2 is used to be placed on a support surface to improve the stability of the dispensing bag during placement;

[0021] In this embodiment, a cut 3 is provided on each of the left and right end faces of the sub-packaging bag body 1, facilitating the tearing of the sub-packaging bag body 1 through the cut 3 to take out the pre-prepared food in the sub-packaging bag body 1;

[0022] As Figures 1 to 3 shown, in this embodiment, a gasket 4 is horizontally pasted on the bottom end face of the support plane 2 through an adhesive layer 7. A number of downwardly protruding convex bodies 5 are provided on the bottom end face of the gasket 4. A cavity 6 is formed inside the convex body 5, which is conducive to collecting moisture through the cavity 6, reducing the infiltration of moisture into the sub-packaging bag body 1, and improving the moisture-proof performance of the sub-packaging bag body 1;

[0023] An aluminum foil film layer 8 is pasted on the inner surface of the sub-packaging bag body 1. An EVOH barrier film 9 is pasted at one end of the aluminum foil film layer 8 away from the sub-packaging bag body 1. A polyethylene moisture-proof film layer 10 is pasted at one end of the EVOH barrier film 9 away from the aluminum foil film layer 8;

[0024] Among them, the upper end portion of the sub-packaging bag body 1 is in a tapered shape that gradually tapers from bottom to top, which helps to reduce the width of the upper part of the sub-packaging bag body 1, thereby reducing to a certain extent the risk of the sub-packaging bag tipping over due to too high a center of gravity or uneven distribution of the contents;

[0025] In this embodiment, a polyvinyl alcohol coating 11 is coated on the outer surface of the sub-packaging bag body 1. The polyvinyl alcohol coating 11 has good barrier properties and can effectively prevent moisture penetration, improving the moisture-proof performance of the sub-packaging bag body 1;

[0026] In this embodiment, the vertical cross-section of the convex body 5 is in a trapezoidal shape that gradually tapers from top to bottom, and the bottom end face of the convex body 5 is parallel to the bottom end face of the support plane 2, which is conducive to the lower surface of the convex body 5 lying flat on the tabletop, and the convex body 5 provides stable support for the sub-packaging bag body 1;

[0027] In this embodiment, the gasket 4 is flush with the side surface of the sub-packaging bag body 1, and the gasket 4 is made of food-grade PET material, which has good oil resistance and moisture-proof properties, and is conducive to providing moisture-proof protection for the sub-packaging bag;

[0028] In this embodiment, the adhesive layer 7 is a water-based acrylate adhesive. The water-based acrylate adhesive is an environmentally friendly adhesive, uses water as a dispersion medium, has a low content of volatile organic compounds, is easy to recycle and decompose, is convenient for recycling, and is more environmentally friendly;

[0029] Specifically, the polyethylene moisture-proof film layer 10 is in safe contact with the pre-prepared food in the packaging bag, and can effectively improve the moisture-proof effect of the packaging bag. The EVOH barrier film 9 provided can effectively prevent oxygen and water vapor from penetrating into the food in the packaging bag body 1, enhancing the moisture-proof and fresh-keeping capabilities of the packaging bag. The aluminum foil film 8 layer has excellent barrier properties and can effectively block light, oxygen, and moisture, making it suitable for pre-prepared food products that need to be stored for a long time or are sensitive to light. Such a multi-layer structure design can significantly improve the moisture-proof performance of the packaging bag;

[0030] Moreover, when the packaging bag body 1 drives the food and places it on a water-containing tabletop, the gasket 4 made of food-grade PET material provides moisture-proof protection for the bottom of the packaging bag body 1. The provided cavity 6 can store the moisture infiltrated into the gasket 4 to a certain extent, reducing the moisture infiltration into the packaging bag body 1, increasing the time for the user to use the pre-prepared food, facilitating the user to use the pre-prepared food before the moisture penetrates into the packaging bag body 1, and helping to reduce the situation of the pre-prepared food getting damp, thus improving the freshness of the consumed pre-prepared food.

[0031] The above are only the preferred examples of the present utility model and are not used to limit the present utility model.
