Can high-salt products affect packaging machine service life?
• Yes, salt (chloride) corrodes stainless and carbon steel, shortening packaging machine life.
• Salt-contact parts should be 316L stainless steel, not 304 or carbon steel.
• Heat-seal jaws, dosing screws, hoppers and formers need anti-corrosion coating or passivation.
• Clean salt residue daily and keep dry to prevent electrochemical corrosion.
• Require salt-spray test ≥48h and specify materials in the contract.
