As shown in fig. 1 to 5, a water storage type application film includes: the bag comprises a waterproof breathable layer 11, a liquid locking layer 12 and an oiled paper layer, wherein the waterproof breathable layer 11 and at least one liquid locking layer 12 are vertically overlapped, and the edges are subjected to hot melt fusion or adhesive sealing to prepare a sealed bag body 1; the bag body 1 is filled with liquid; a circle of adhesive layer 14 is arranged on a sealing edge 13 on one side of the liquid-locking layer 12, and at least one micropore 15 is arranged on the surface of the liquid-locking layer 12, or a plurality of micropores 15 are arranged at intervals and in a matrix manner; the micropores 15 are tiny through holes, and the diameter of the micropores 15 is 0.001-3 mm; the surface of the liquid locking layer 12 is covered by at least one oil paper layer in a fitting manner; the 1-shaped plaster patch or the whole facial mask of the bag body is hermetically packaged in a packaging bag with waterproof and air-blocking functions.

Specifically, the waterproof breathable layer 11 and the liquid-locking layer 12 are vertically overlapped in a plan view, the edges are fused by hot melting or by adhesive to form a sealing edge 13, and one adhesive layer 14 is provided on the surface of the sealing edge 13 on one surface of the liquid-locking layer 12. The middle area is a liquid-locking layer 12, and liquid is filled between the liquid-locking layer 12 and the waterproof breathable layer 11. The surface of the liquid-lock layer 12 is provided with a plurality of micropores 15 arranged in a matrix. The liquid-lock layer 12 and the adhesive layer 14 are integrally covered and connected by an oiled paper layer.

The oiled paper layer on the surface of the bag body 1 is torn off, the bag body 1 is attached to the surface of skin or an object, and the ring-shaped adhesive layer 14 on the surface of the sealing edge 13 of the bag body 1 is adhered to the surface of the skin. The loop-shaped adhesive layer 14 provides a closed space structure between the skin or object surface and the liquid-lock layer 12. The outer surface of the waterproof and breathable layer 11 of the bag body 1 is pressed, and the liquid flows out from the micropores 15 of the liquid-locking layer 12 to the surface of the skin. The liquid in the bag body 1 is uniformly smeared on the surface of the skin by repeatedly pressing and rubbing the surface of the waterproof and breathable layer 11 of the bag body 1. The liquid is medicinal liquid, care solution, nutritional liquid, alcohol, essential oil, lotion, floral water, cosmetic water, ointment or other liquid preparation.

And the area of the waterproof breathable layer 11 is larger than that of the liquid locking layer 12. The central area of the waterproof breathable layer 11 is connected and distributed with a liquid locking layer 12. A circle of adhesive layers 14 are distributed on the surface of the waterproof and breathable layer 11 around the liquid-lock layer 12 and the edge surface of the liquid-lock layer 12. The liquid-lock layer 12 and the adhesive layer 14 are integrally covered and connected by an oiled paper layer.

The waterproof breathable layer 11 is made of a plastic film with waterproof and breathable functions, and is waterproof and breathable. Effectively prevent the human skin from generating uncomfortable feeling after being attached to the skin. The waterproof breathable layer 11 may be specifically a PU film. On the surface of the liquid lock layer 12, micropores 15 with a smaller diameter are formed by laser drilling or physical drilling, and the diameter of the micropores 15 is between 0.001 mm and 3 mm. Typically the micropores 15 are no larger than 0.3mm in diameter. The liquid in the pouch body 1 does not normally exceed 30 ml. When the liquid in the bag body 1 exceeds 20ml, the liquid-lock layer 12 can adopt a double-layer plastic film structure. Thus, the pores 15 in the liquid-lock layer 12 effectively prevent the liquid from flowing out from the inside of the liquid-lock layer 12 by the tension. An oilpaper layer is bonded to the surface of the liquid-locking layer 12, and the oilpaper layer is used for dust prevention and also for preventing the liquid in the bag body 1 from evaporating through the micropores 15 of the liquid-locking layer 12. Wherein, the adhesive layer 14 is bonded with the oiled paper layer, so that the sealing connection effect can be effectively realized. The prepared plaster or facial mask is packed in an aluminum-plastic composite film bag with good waterproof and air-proof effects for standby.

The liquid-retaining layer 12 is usually a single layer, and two plastic films or multiple plastic films may be disposed to overlap each other as needed. The micropores 15 in the two adjacent plastic films are not overlapped, and a certain spacing distance is kept between the micropores 15, wherein the spacing distance is more than 1 mm. The purpose is to reduce the liquid pressure intensity on the micropores 15 and ensure that the micropores 15 do not leak when a large amount of liquid is in the bag body 1.

The oiled paper layer is a whole piece of oiled paper, the waterproof surface of the oiled paper layer is attached to the liquid locking layer 12, and the edges of the oiled paper layer are bonded and hermetically connected by the adhesive layer 14 at the edge of the liquid locking layer 12. The surface of the liquid-holding layer 12 can be covered by splicing and combining two pieces of oilpaper according to requirements. The edge of the oil paper layer is provided with an easy-tearing strip, and the surface of the easy-tearing strip is not provided with an adhesive layer 14.

According to the needs, a ring is arranged in the bag body 1, and the front surface and the back surface of the ring are respectively connected with the surfaces of the waterproof breathable layer 11 and the liquid locking layer 12 in a sealing manner through hot melting fusion or adhesive bonding. The liquid is filled into the ring for storage.

Besides, a grid panel can be placed in the bag body 1, the surface of the grid panel is provided with a plurality of through holes which are mutually spaced and are arranged in a matrix, and the diameter of each through hole is 0.1-5 mm. Typically 2-3mm, and a thickness of between 0.1-5mm, typically 1-3 mm. The through-hole accumulates liquid by tension. When the latticed panel is pressed, the latticed panel is contacted with the liquid-lock layer 12 and the surface of the skin, the tension action is damaged, the liquid flows out from the through holes, and the liquid flows to the surface of the skin or an object through the micropores 15 of the liquid-lock layer 12 to be smeared.

According to the requirement, one surface of the latticed panel is fused on the surface of the waterproof breathable layer 11 in a hot melting mode or is adhered to the surface of the waterproof breathable layer in an adhesive mode, the other surface of the latticed panel is provided with an adhesive layer 14, and the adhesive layer 14 and the oiled paper layer are in peelable low-strength adhesive connection. Liquid is stored in the through holes of the latticed panel. The latticed panel is an environment-friendly degradable plastic product or rubber product, and has bendability and certain flexibility. When the latticed panel adhesive layer is used, the oil paper layer is torn, the adhesive layer of the latticed panel is attached to the surface of skin or an object, and the liquid tension in the through holes of the latticed panel is damaged and flows to the surface of the skin. The waterproof and breathable layer 11 on the other side of the latticed panel plays a role in preventing liquid from flowing out and ventilating.

According to the requirement, the waterproof breathable layer 11 and the liquid locking layer 12 are cut into a mask shape and are overlapped up and down, and the edges of the two layers are subjected to hot melting fusion or adhesive bonding connection. Wherein, the surface of the liquid locking layer 12 is covered with a layer of oil paper; the facial mask with the water storage function is prepared. If necessary, an adhesive layer 14 is provided on the surface of the sealing edge 13 of the liquid-impermeable layer 12, at the sealing edge 13 formed at the edge of the waterproof and breathable layer 11 and the liquid-impermeable layer 12. When the liquid-proof bag is used, the oil paper layer is torn, the liquid-proof layer 12 is attached to the face of a user, the waterproof breathable layer 11 is properly pressed, and liquid in the bag body 1 is released from the micropores 15 of the liquid-proof layer 12 and is coated on the face of the user. The adhesive layer 14 at the edge of the liquid lock layer 12 serves to prevent liquid from flowing to the area outside the mask.
