06 -- Quality Assurance

Tested Beyond
Industry Standards

Every batch undergoes multi-stage inspection. We verify seal integrity, tensile strength, and real-world durability before any shipment leaves the factory.

FDA LFGB CE RoHS REACH ISO 9001
Test 01

Seal Integrity Test
Pressurized air injection combined with underwater observation verifies zero leakage at the zipper closure. Every production run is sampled per AQL 1.5.
Test 02

Leak & Liquid Containment
Bags filled with colored liquid are inverted, shaken, and left under pressure for 24 hours to verify zero liquid escape through seams and closures.
Test 03

Tensile & Tear Strength
Universal testing machines verify elongation at break ≥400% and tear resistance exceeding food-grade silicone industry benchmarks.
Test 04

Reusability Cycle Test
Repeated open/close zipper cycles (1000+) and dishwasher-cycle simulations confirm long-term durability without seal degradation.
Test 05

Temperature & Aging
Constant temp & humidity chamber tests simulate 3+ years of use. Freeze-microwave cycle testing confirms material stability from -40°C to 230°C.
