We manufacture food jars in three premium materials, each with unique advantages:

Stainless Steel (304/316 Grade):

Best for: Durability, temperature retention (6–24 hours), and eco-friendliness.

Ideal für: Hot/cold meals, outdoor use, or premium brands. Resists rust and odors.

Glass (Borosilicate):

Best for: Chemical-free storage, microwave safety, and aesthetic transparency.

Ideal für: Baby food, reheating, or brands targeting eco-conscious consumers.

Food-Grade Plastic (PP, Tritan™, BPA-Free):

Best for: Lightweight affordability and customizable colors/designs.

Ideal für: Budget-friendly lines, kids’ products, or single-use packaging.

Need help deciding? Share your use case (e.g., insulation needs, target market), and we’ll recommend the best material.

Our vacuum-insulated food jars maintain temperatures for 6–12 hours (hot) and 12–24 hours (cold), depending on the model and initial food temperature. For best results:
Pre-heat/pre-chill the container before filling.
Seal tightly to prevent air exposure.
Avoid opening repeatedly during use.

Absolutely. Our 304/316 stainless steel is inert and won’t react with acidic or alkaline foods. For dairy, ensure the container is thoroughly cleaned after use to prevent odor retention.

Always store food at safe temperatures: above 140°F (60°C) for hot oder below 40°F (4°C) for cold.

Clean the jar immediately after use with warm, soapy water, and dry completely.

Avoid leaving moist food residue inside for extended periods.

Double-walled vacuum insulation is the gold standard. It creates an airless space between walls to block heat transfer, outperforming foam or single-layer designs. Our jars use this technology for maximum efficiency.

Yes! We offer:

Leak-proof silicone seals for spill resistance.

Eco-friendly lids (bamboo, PP plastic, or stainless steel).

Ergonomic additions like carrying straps, foldable handles, or dividers for bento boxes.

Our minimum order quantity starts at 500–1,000 units (varies by design complexity). Smaller trial orders may be possible—contact us to discuss flexibility for startups.

Yes. Anhui iFun respects intellectual property. We’ll gladly sign an NDA or NNN agreement before reviewing your sketches or specifications. All shared data is stored securely, and projects are handled by a dedicated manager.

We implement:

Strict QC checks at each production stage (material sourcing, molding, insulation testing, etc.).

Third-party lab certifications (FDA, LFGB, SGS) for safety compliance.

Batch sampling before shipment to verify durability, temperature retention, and finish.

We can inspire functional improvements (e.g., better insulation, lid design) but don’t copy patented designs. Share your ideal features, and we’ll engineer a unique solution tailored to your brand.

Typically 10-25 days after finalizing designs (depending on order size and customization). Rush production may be available—ask our team for expedited options.
