Abstract

The invention relates to a dehydration sensitive time indicating device. A dehydration-sensitive time indicating device, characterized in that it comprises: a base layer; a first base material layer, which forms a first storage body capable of blocking gas with the base layer; a dry adsorption layer, which is stored in the first storage body In the body, the dry adsorption layer contains a dry adsorption material that can absorb moisture; the second base material layer forms a second container that can block gas with the first base material layer, and the second base material layer is transparent material; and an indicating functional layer, accommodated in the second container, the indicating layer contains a dehydration discoloration material, and the dehydration discoloration material is selected from copper sulfate pentahydrate, cobalt chloride hexahydrate, trichloride hexahydrate At least one of iron and copper chloride dihydrate; the dehydration sensitive time indicating device also includes at least one of a barrier layer and an adhesive layer, and the barrier layer can be attached to the second substrate layer or On the surface of the base layer, the adhesive layer is stacked on the surface of the base layer away from the first substrate layer. The above dehydration sensitive time indicating device can avoid pollution to the external environment.

Description

Technical field [0001] The invention relates to a water loss sensitive time indicating device. Background technique [0002] Food, beverages, blood, vaccines, meat and other perishable products need to be stored in a specific temperature environment. If the storage environment temperature exceeds the specified temperature, the items to be inspected will quickly deteriorate. Consumers use the above deteriorating items to be inspected. , Will cause damage to the human body, and even cause death in severe cases. Therefore, it is necessary to provide an indicating device that can continuously change color sensitive to temperature, so as to determine the accumulated heat of the product to be inspected by the degree of color change, and thereby determine whether the stored article to be inspected has failed. The existing dehydration-sensitive time indicating device includes a base layer, an indicating function layer and a protective layer formed on the surface of the base layer, the i...
