Irreversible color-changing printed matter base material for cold-chain food

The utility model relates to an irreversible color-changing printed matter base material for cold chain food, which comprises a printed matter base material and a first base layer, and is characterized in that the outer side of the printed matter base material is connected with an ink layer, one side of the ink layer is attached to the printed matter base material, one side of the ink layer far away from a printed matter is connected with the first base layer, and the printed matter base material is made of a packaging container. The first base layer is made of gloss oil or a polyolefin copolymer, the gloss oil is food-grade water-based gloss oil, the polyolefin copolymer is food-grade polyolefin copolymer, and the ink layer is irreversible color-changing organic ink. The printing base material can be used in a cold chain environment, irreversible color-changing ink is used, normalization of storage and transportation conditions of products can be visually judged, compared with a temperature and humidity reco
