Product Description
Rust – proof tinplate lids caps for long – term canned food storage
Rust-Proof Tinplate Lids Caps for Long-Term Canned Food Storage
Size: Available in 63mm, 73mm, and 83mm diameters (fits standard canned food jars and tins); height 12mm; curl edge design for secure sealing; compatible with twist-off or pry-off jar necks.
Color: Natural silver tinplate (default) with optional gold or white epoxy coating (custom colors available for orders over 10,000 units); printed branding options via offset printing.
Sealing Feature: Rubber gasket (food-grade silicone) embedded in the inner rim for airtight closure.
Applications
Designed for food canneries, home canning supply brands, and emergency food storage companies. Ideal for sealing glass jars or metal tins containing preserves, pickles, canned fruits, vegetables, meat, and dry goods (e.g., beans, rice) for long-term storage.
Features & Advantages
Core Function: Creates an airtight, rust-proof seal to preserve canned food’s freshness, flavor, and nutritional value over extended periods. The tinplate construction withstands humid storage environments, preventing corrosion that compromises food safety.
Benefit: Resists rust even in high-humidity storage (e.g., basements, pantries) for up to 5 years—outperforming standard tin lids that rust within 12–18 months, reducing food waste from spoiled canned goods.
Benefit: Forms a leak-proof seal that blocks oxygen and moisture, extending shelf life by 30% compared to lids with rubber gaskets that degrade over time—ensuring canned food stays safe for long-term emergency storage.
Attribute: Reusable design (up to 5 times with proper cleaning).
Benefit: Saves costs for home canners and small businesses, unlike single-use aluminum lids—providing eco-friendly value without sacrificing sealing performance.
Quality Assurance: Produced in an ISO 22000-certified facility (food safety management). Tested to 500+ hours of salt spray exposure (ASTM B117 standard) with zero rust formation; gasket material meets FDA 21 CFR 177.2600 standards for food contact.
User Value
Scenario: A family-run jam company uses these rust-proof tinplate lids for their 8oz glass jars of strawberry preserves. Stored in a warehouse with varying humidity, the lids remain rust-free after 2 years, while a batch sealed with cheaper lids shows rust spots and swollen jars (signaling spoilage). Home canners also appreciate the lids—reusing them for seasonal pickles year after year, with each seal holding tight to keep cucumbers crisp and vinegar-brined.
User Benefits: Reduces product loss from rust-related spoilage; lowers long-term packaging costs via reusability; ensures compliance with food safety standards; builds trust with customers (no rust-stained jars on store shelves).
Packaging & Shipping
Each lid is individually wrapped in food-grade wax paper; bulk packed in corrugated cardboard boxes (5,000 units per carton) with moisture-absorbing packets to prevent humidity damage during transit.
Shipping via UPS Ground (3–5 days) for domestic orders; DHL (7–10 days) for international shipments; sea freight (4–6 weeks) for container-sized bulk orders.
After-Sales Service
2-year warranty: Free replacement for lids that show rust within the first 24 months under normal storage conditions.
30-day returns: Full refund for unused stock if size or fit does not match your cans/jars.
Technical support: Free guidance on lid sizing for custom jar dimensions; sample testing with your specific food products (acidic vs. low-acid) to verify seal integrity.
FAQ
Are these lids suitable for acidic foods like tomatoes or citrus preserves?
Yes, the epoxy coating resists corrosion from acidic ingredients—tested with pH 3.5 solutions (e.g., tomato sauce) for 2 years with no degradation.
Can they be used with pressure canning methods?
Absolutely, the tinplate and silicone gasket withstand pressure canning temperatures (up to 250°F/121°C) without warping or seal failure.
What’s the minimum order quantity?
1,000 units for standard silver lids; 10,000 units for custom colors or printed branding.
How should I clean and reuse the lids?
Wash with warm, soapy water; avoid abrasive scrubbers (to protect the anti-rust coating). Air-dry thoroughly before reusing to maintain the gasket’s seal.
Do the lids have a “pop” indicator for freshness?
Yes, optional pressure-sensitive buttons are available (on 73mm and 83mm sizes) that pop up when the seal is broken, signaling potential spoilage.
Are they recyclable after their lifespan?
Yes, the tinplate is 100% recyclable; remove the silicone gasket before recycling (check local guidelines for plastic components).
