[0001] The utility model relates to ice bag technical field, concretely is a kind of non-woven fabric structure for self-water-absorbing ice bag. BACKGROUND
[0002] Ice bag is a novel freezing medium, and it does not pollute water quality when thawing, can be used repeatedly, and can be used for cold and heat. The effective cold capacity of ice bag is 6 times that of ice with the same volume, which can replace dry ice and ice cubes.
[0003] It is mainly used for cold storage and power saving in daily life, maintaining low temperature when the refrigerator is powered off, food preservation, iced beverages and travel.
[0004] The ice bag currently used is usually formed by hot pressing a plastic film layer and a non-woven fabric layer. The ice bag is filled with water-absorbing resin particles. Water enters the inside of the ice bag through the non-woven fabric layer, and after contacting the water-absorbing resin, the water-absorbing resin absorbs water and expands. Due to the use of the non-woven fabric layer, water enters the inside of the ice bag quickly. Due to the nature of the non-woven fabric material itself, the surface of the non-woven fabric is easy to get wet. After the water freezes, it becomes solid ice. When the non-woven fabrics of two ice bags are close to each other and are frozen, it is difficult to separate them. Even if they are separated, the non-woven fabric is easy to tear and damage. SUMMARY
[0005] The utility model discloses a non-woven fabric structure for self-water-absorbing ice bag to solve the problem that the surface of the non-woven fabric is easy to get wet due to the nature of the non-woven fabric material itself, and the water becomes solid ice after freezing. When the non-woven fabrics of two ice bags are close to each other and are frozen, it is difficult to separate them. Even if they are separated, the non-woven fabric is easy to tear and damage.
[0006] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a non-woven fabric structure for self-water-absorbing ice bag, comprising:
[0007] a non-woven fabric layer and a plastic film layer;
[0008] The two sides of the plastic film layer are provided with non-woven fabric layers, and the two sides of the plastic film layer are sealingly connected with the non-woven fabric layers at the contact positions.
[0009] The middle part of the plastic film layer is provided with an indentation.
[0010] Preferably, the two sides of the plastic film layer are hot-pressed to form a heat-sealing layer at the contact positions with the non-woven fabric layers.
[0011] Preferably, the distance between the outer edge of the non-woven fabric layer and the side edge of the plastic film layer is 2.5-3.5 cm.
[0012] Preferably, the non-woven fabric layer is provided with two non-woven fabric layers, and the two non-woven fabric layers are sealingly connected to the two sides of the plastic film layer.
[0013] Preferably, the non-woven fabric layer is provided as one, and the plastic film layer covers the middle part of the surface of the non-woven fabric layer.
[0014] Preferably, the non-woven fabric layer is folded back to form a rolled edge on the side close to the plastic film layer.
[0015] Preferably, the two non-woven fabric layers are connected by a non-woven fabric strip on the side close to each other.
[0016] Compared with the prior art, the utility model has the beneficial effects that:
[0017] In actual use, after filling water in the ice bag, the ice bag is inflated, so that the plastic film layer in the middle part is convex (the non-woven fabric layer is less convex than the plastic film layer), and the contact between the ice bags is mainly the contact of the plastic film layer, so that the ice bag is not easy to freeze and stick together due to the smooth surface of the plastic film layer.
