The invention provides a method for increasing the cover making speed through aluminum waxing and provides an additive mutually soluble with wax. The additive is required to meet the food requirements, and it is proved by pepsi tests that floating wax does not float. After a certain proportion of edible glycerinum and wax are subjected to mixed dissolution, the requirement for high-speed cover making can be met while the quality safety of subsequent canned food is not influenced with a small amount of wax. The additive is an alcohol type substance, and a typical product is glycerin which is commonly known as the edible glycerinum. The method is scientific in principle, the use method is simple and easy to perform, and the effect of increasing the cover making speed is obvious.
