Abstract

The invention discloses a formula and a preparation process of a food can inner wall coating, and relates to the technical field of can processing. The invention is characterized in that: according to the formula, the coating is prepared by combining four mixtures, namely 700kg of material A, 100kg of material B, 60kg of material C and 140kg of material D; and the preparation process comprises the following steps of: putting the material A into a container, stirring, pouring the material B, the material C and the material D, continuously stirring for 60 minutes, discharging, and filtering. The process is simple, food in a can is quickly taken out, the coating has high food corrosion resistance, the safety of the food is improved, and the storage time of the food is prolonged.

Description

technical field [0001] The invention relates to the technical field of can processing, in particular to a formula and a manufacturing process of a coating for the inner wall of a food can.
