Certifications & Quality Assurance

We prioritize safety, durability, and customization integrity, with every jar undergoing rigorous testing to meet global standards:

● Food Safety Certifications: FDA (U.S.) and LFGB (EU) compliance for glass and silicone seals, ensuring no harmful chemicals leach into contents.

● Material Testing: Soda-lime glass is certified for thermal shock resistance (surviving 90°C temperature changes) and impact resistance (passing 18+ drop tests from 1m height).

● Factory Standards: Our production facility is ISO 9001 certified, with strict quality control from glass blowing to lid assembly and customization.

● Quality Control Process:

1. Seal Leak Test: Each lid is pressure-tested to confirm 100% leak-proof performance when inverted.

2. Customization Adhesion Test: UV prints and engravings are subjected to 60+ dishwasher cycles to verify scratch and fade resistance.

3. Stack Load Test: Jars are stacked with 10kg of weight to confirm stackable base durability.

4. Final Audit: A 5% sample of each batch is inspected for clarity, seal integrity, and customization alignment.

Customization & Production Process

We offer end-to-end customization tailored to brand and functional needs, with a focus on maximizing visibility and versatility:

● Custom Options:

o Branding: Full-color UV printing (jar/lid), laser engraving, or matte glaze accents for logos, patterns, or product information.

o Design Tweaks: Custom jar capacities, lid colors, or silicone seal textures for bulk orders (minimum 2000 units).

o Packaging: Branded foam-lined gift boxes (for retail/gifting) or bulk stackable cartons (for commercial storage).

● Production Workflow:

1. Design Confirmation: Our team reviews your artwork and provides free digital mockups to test 360° customization placement.

2. Sample Making: Pre-production samples (jar + lid + customization) are ready in 5–7 business days (custom samples incur a fee, refundable on orders ≥3000 units).

3. Mass Production: Jars are blown, lids are assembled with silicone seals, and customization is applied via UV printing or engraving.

4. Final Quality Check: All units are verified for seal integrity, customization durability, and thermal resistance.

5. Packaging & Shipping: Securely packed in foam-lined cartons to protect glass surfaces and printed designs during transit.
