Technology & Craftsmanship
We specialize in high-frequency heat-sealing technology to create truly waterproof and airtight bag products. This insulated bag uses high-strength TPU material for both the outer and inner layers, with a thickened PE foam insulation layer in between. Through high-frequency heat-sealing, the three layers are completely fused—no needle holes, no seams—effectively solving the leakage issues common in traditional stitched bags. The airtight zipper is tested for over 500 open/close cycles, ensuring a perfect seal even after long-term use.
