  Food and pharmaceutical companies often have specific requirements for packaging equipment, with most mandating the use of stainless steel construction. Stainless steel comes in various grades—commonly 201, 304, and 316—each available in multiple specifications. The grade selected directly impacts both the price and performance of the packaging machine.

  Grade 304 stainless steel is widely used in industrial equipment, containing a minimum of 8% nickel. It offers superior corrosion resistance compared to the 200 series and is particularly well-suited for packaging corrosive food products. As a general-purpose austenitic stainless steel, 304 exhibits excellent rust and corrosion resistance, good resistance to intergranular corrosion, and performs reliably at high temperatures (with a continuous service temperature typically below 650°C). In laboratory testing, 304 stainless steel demonstrates strong resistance to oxidizing acids—specifically, it withstands boiling nitric acid at concentrations up to 65%. It also shows good corrosion resistance against alkaline solutions, as well as most organic and inorganic acids.

  Standard case sealers are typically constructed from powder-coated carbon steel. However, in certain applications—especially in hygienic or corrosive environments—customers require stainless steel for enhanced durability and appearance. Stainless steel case sealers generally fall into two categories:

  1. Stainless Steel Exterior / Frame: The most common type, where the machine frame and outer panels are made of stainless steel to prevent surface corrosion while maintaining cost efficiency.

  2. Full Stainless Steel Construction: The highest-grade option, where all structural and exposed components are fabricated from stainless steel—except for parts that cannot be made from metal (e.g., conveyor belts, rubber rollers, casters). This design maximizes corrosion resistance and minimizes the risk of contamination or damage to sensitive packaged goods.
