In order to improve the durability and hygiene of packaging machine containers and ensure that they meet the safety standards of the food industry, our company has comprehensively optimized the surface polishing process of food-grade stainless steel containers. This process standard is applicable to the production process of various packaging machine containers, aiming to provide customers with more efficient and safer equipment components.
Core Process Requirements
Material Pretreatment: The packaging machine container uses 304 or 316 food-grade stainless steel substrate to ensure that the material is corrosion-resistant and has no risk of heavy metal precipitation.
Combination of rough polishing and fine polishing: Through multiple mechanical polishing processes, the fine scratches on the surface of the container are gradually eliminated, the finish is improved to a mirror effect, and residual impurities are avoided.
Deburring: For the edge and welding position of the container, the automated polishing equipment is used for fine processing to ensure that there are no sharp burrs and meet the safety specifications of food contact surfaces.
Cleaning and passivation: After polishing, use a neutral detergent to thoroughly remove oil stains, and use electrolytic passivation technology to enhance the anti-oxidation ability of the stainless steel surface and extend the service life of the packaging machine container.
Process advantages
The optimized polishing process significantly improves the sealing and cleaning efficiency of the packaging machine container. The mirror-grade surface can effectively reduce material residues and is suitable for high-sanitation scenarios such as milk powder and condiments. At the same time, the container after passivation can still maintain stable performance in a humid environment, reducing the frequency of equipment maintenance.
Industry adaptability
This process strictly follows the GB 4806.9-2016 food contact metal material standard, and is compatible with European and American food machinery hygiene certification requirements to meet the diversified needs of domestic and foreign customers for packaging machine containers.
Through continuous optimization of surface polishing technology, our company is committed to providing safer and more reliable packaging machine container solutions for the food and pharmaceutical industries, helping companies improve production compliance and product quality.
