[Glen Dale, WV] — April 2026 —At Americanner, quality is not a checkpoint—it’s a continuous process embedded in every stage of our manufacturing. From raw material sourcing to final packaging, our quality assurance system is designed to deliver safe, reliable, and high-performance home canning closures you can depend on.
End-to-End Quality Assurance Process
- Incoming Raw Material Inspection
Quality begins before production starts. Every batch of raw materials undergoes strict verification:
- Steel thickness and coating compliance (electrolytic tinplate)
- Validation of food-safe lacquer systems (BPA-free, PFAS-free or compliance with FDA regulations)
- Inspection of gasket/liner materials for uniformity, flexibility, and cleanliness
- Precision In-Process Controls
During manufacturing, we implement real-time quality monitoring to ensure consistency:
- Bands: Thread integrity, dimensional accuracy, burr-free edges, and uniform finish
- Lids: Correct panel curvature, precise gasket application, and proper button (popper) installation
- Automated Vision Systems: High-speed quality cameras detect even the smallest defects over 100% of production.
- Functional Performance Testing
We validate product performance under real-world canning conditions:
- Simulated vacuum seal testing on random samples
- Torque and closure retention testing
- Verification of button pop functionality for seal indication
- Hygiene & Contamination Control
Food safety is non-negotiable. Audits are regularly conducted internally or by appointed independent third parties. We maintain strict cleanliness standards:
- Visual inspection for particulate contamination
- Monitoring for residues or lubricants
- Optional microbiological swab testing to ensure sanitary conditions
- Final Quality Control & Packaging Verification
Before any product leaves our facility, it undergoes a comprehensive final check:
- 100% visual or camera-based inspection
- Verification of lot code traceability
- Confirmation of labeling accuracy, product count, and packaging integrity
Proven Performance Through Rigorous Testing
Our closures are subjected to extensive laboratory validation designed to replicate real home canning environments:
- Hot Fill Testing at 98°C
- Water Bath and Pressure Canning Simulations
- Autoclave Testing for extreme conditions
- 24-Hour Cooling Cycles to assess vacuum retention
Results You Can Rely On
- No seal failures
- No vacuum loss
- No lid collapse
- Consistent performance across all fill levels and conditions
Safe by Design, Responsible by Choice
Our sealing compounds are engineered with both safety and sustainability in mind. We proudly own the know-how of formulating the gaskets and specify the state-of-the-art coating system:
- 100% food-safe and FDA-compliant
- Free from PFAS, PFOA, PFOS, BPA-NI, and phthalates
- Designed to maintain performance while reducing environmental impact
- Carbon footprint is minimized by sourcing domestically, optimizing transportation and generating over 50% of the necessary energy from renewable sources.
We continuously refine our materials and processes to meet evolving safety standards and sustainability expectations.
