Food Grade FDA Compliant Steel Embossing Roller 316L Stainless Mirror Polish for Packaging Film

This food-grade steel embossing roller is purpose-built for direct and indirect food contact applications in the packaging, confectionery, and beverage industries. Manufactured entirely from 316L stainless steel, a molybdenum-enhanced austenitic alloy renowned for its superior corrosion resistance and biocompatibility, this roller meets the stringent requirements of FDA 21 CFR 175.300 for resinous and polymeric coatings intended for food contact surfaces.

Every production batch undergoes material certification, surface roughness verification, and trace element analysis to confirm regulatory compliance before shipment. The 316L construction maintains structural integrity and surface purity even under continuous exposure to acidic or alkaline food products, while the mirror-polished surface eliminates micro-crevices where bacteria and food residues could accumulate.

Key Features

316L Stainless Steel Body: Molybdenum-alloyed austenitic stainless steel provides exceptional resistance to pitting corrosion from chloride-containing food products. The low carbon content (0.03% max) prevents intergranular corrosion after welding or thermal processing.
FDA 21 CFR 175.300 Compliance: Surface materials and coatings comply with FDA regulations, supported by third-party laboratory certification documentation provided with every order.
Mirror Polish Ra 0.05μm: Electropolished and mechanically finished to near-optical smoothness, eliminating bacterial adhesion sites and ensuring complete product release without residue buildup.
ISO Class 7 Cleanroom Assembly: Final assembly, inspection, and packaging conducted in a controlled environment maintaining fewer than 352,000 particles per cubic meter.
Salt Spray Resistance 500+ Hours: Validated through ASTM B117 neutral salt spray testing, withstanding over 500 hours of continuous saline exposure without pitting or surface degradation.
Full Material Traceability: Each roller accompanied by heat number certificate, chemical composition analysis, and mechanical property report tracing raw material back to the originating mill heat.

Applications

This FDA-compliant embossing roller is engineered for food packaging film embossing, confectionery mold pressing, beverage carton texturing, pharmaceutical blister pack forming, dairy product wrapper embossing, and baked goods packaging where direct or indirect food contact is involved. The 316L stainless construction is also suitable for cosmetic cream packaging, medical device pouch sealing, and sterile barrier film processing where material purity and cleanroom compatibility are essential.

Packaging & Quality Assurance

Each roller undergoes ultrasonic cleaning, DI water rinsing, and ISO Class 7 cleanroom drying before being vacuum-sealed in anti-static film with desiccant packs. The sealed unit is encased in custom-cut high-density foam and placed in a fumigated plywood export crate. Documentation includes FDA compliance certificate, material mill test report (EN 10204 3.1), surface roughness profilometer trace, and dimensional inspection report. A 12-month warranty covers material and workmanship defects, with expedited replacement available for critical production lines.
