  • Waterproof Backpack Factory: Production and Quality Assurance

    Sealock operates waterproof backpack factories in Dongguan, China and Ho Chi Minh City, Vietnam, producing OEM and wholesale packs for outdoor brands and importers. A waterproof backpack factory has to run two production disciplines at once — high-frequency welding for the waterproof body and industrial sewing for the load-bearing structure — and the order in which they happen determines whether the pack stays sealed. This is how the line is organised, and how quality is assured from incoming roll to the customer's own inspection.
