The invention discloses a food bag with a cooling function, which comprises a backing layer, a gel layer, a breathable layer and an isolation layer from outside to inside. The backing layer is made of polyethylene blown film, the gel layer is a macromolecule hydrogel, and the breathable layer is made by punching holes of paper plastic composite material, and the isolation layer is composed of PET film, and the thickness of the backing layer is 0.3 0.5mm. The thickness of the layer is 2 4 mm, the permeable layer thickness is 0.8 1.2 mm, and the isolation layer thickness is 0.3 0.5 mm. The invention is a food bag with a cooling function, and the macromolecule water gel layer is the main structure. The utility model utilizes physical principles to heat the glue into the colloidal substance, and the heat in the surrounding environment is quickly evaporated by the water in the gel to remove the heat in the surrounding environment, so as to achieve the purpose of cooling. The backing layer and the isolation layer ensure that the gel layer does not play a role in the food bag when it is not used, and when using the food bag, the food bag is used as a food bag. Only by separating the isolation layer directly and exposing the breathable layer inside, the gel layer can be evaporated through the pores on the air permeable layer to cool down, so that the frozen food packaged in the food bag will not be quickly thawed or melted, so that people can live.
【技术实现步骤摘要】
一种具有降温功能的食品袋
本专利技术涉及塑料薄膜加工领域,具体涉及一种具有降温功能的食品袋。
技术介绍
随着商品经济的发展,盛装食品的塑料袋使用越来越广泛,但是,虽然塑料袋制作工艺不断的进行改进,依旧存在着很多的不足和不便,例如,冷冻类食品在售出后使用塑料袋盛装带回家的过程中非常容易解冻或者融化,从而使食品变质,非常的不方便,故研制一种具有降温功能的食品袋对解决这一问题非常的必要。本专利技术介绍了一种具有降温功能的食品袋,高分子水凝胶层为其主要结构,其利用物理原理可将热量集中到胶状物,通过凝胶中水分快速蒸发带走周围环境中的热量,达到降温目的,背衬层和隔离层保证了食品袋在不使用时凝胶层不与外界接触发挥作用,使用食品袋时只需将隔离层直接撕下,露出里面的透气层,凝胶层便可通过透气层上的孔进行水分蒸发进行降温,从而使食品袋盛装的冷冻食品不会快速解冻或融化,方便人们生活。
技术实现思路
针对现有技术的不足,本专利技术的目的在于提供一种具有降温功能的食品袋。本专利技术解决的技术问题可以采用以下技术方案来实现:一种具有降温功能的食品袋,由外到内依次包括背衬层、凝胶层、透气层和隔离层 ...
