Abstract

The invention provides vaccine cold storage packaging paper and a preparation method thereof. The vaccine cold storage packaging paper comprises a body paper layer, a coating layer and a back coating layer, wherein the upper surface and the lower surface of the body paper layer are coated with the coating layer and the back coating layer respectively; the body paper layer comprises a surface paper layer, a core paper layer and a bottom paper layer which are sequentially stacked from top to bottom; the coating layer comprises a surface coating, a core coating and a pre-coating from top to bottom; a rosin sizing agent for improving the smoothness and strength of the paper is added into the body paper layer, and a silane coupling agent/acrylate water-resistant agent for controlling the Cobb values of the surfaces of different pulp layers to improve the water resistance of the paper is added into the coating layer; a wet strength agent for improving the wet strength of the paper under a low-temperature refrigeration condition is added into the body paper layer, and the wet strength agent accounts for 10-18 kg per ton of paper of the whole packaging paper. The vaccine cold storage packaging paper has high water resistance and high humidity strength, and can still effectively keep complete packaging and stable performance of packaged vaccines in low-temperature refrigeration/freezing and cold-chain transportation environments.

Description

【Technical field】 [0001] The invention relates to papermaking technology, in particular to vaccine refrigerated wrapping paper and a preparation method thereof. 【Background technique】 [0002] Refrigerated medicine is the abbreviation of low-temperature, refrigerated storage medicine. This kind of medicine has very strict requirements on the storage and transportation temperature in the process of circulation. According to the regulations under the "storage" item of drug standards in the Pharmacopoeia of my country, it usually refers to drugs that need to be stored, kept and transported in a cold place (meaning that the temperature meets 2°C to 10°C). Taking vaccines as examples, such as tetanus, diphtheria, and type B Hepatitis, whooping cough, inactivated poliovirus and COVID-19 vaccine, etc. [0003] Insulation packaging refers to a special packaging form that can ensure that temperature-sensitive products are always within a reasonable temperature range in all links from...
