  • TPU Dry Bags: Material Advantages for Premium Waterproof Products

    Sealock is a TPU dry bag manufacturer supplying premium waterproof bags to outdoor brands and importers sourcing at the material level. For a procurement team, the choice between TPU, PVC, and PU is not a detail — it decides weight, cold-weather behavior, service life, hand-feel, and compliance, and it is the single factor most responsible for why two bags that look identical online perform completely differently after a season. This is what TPU actually delivers as a material, where its cost is justified, and where it is not.

  • Waterproof Backpack Production Process Explained

    Sealock manufactures waterproof backpacks for OEM and wholesale buyers across factories in China and Vietnam, and the production process is worth understanding before placing an order rather than after. Brands that know how a pack is actually built waste fewer revisions, catch quality risks earlier, and set timelines that match how factories really work. This walks the full sequence in order — what happens at each stage, where the buyer's decision points sit, and which steps cannot be undone once passed.

  • Inside a Bikepacking Frame Bag Program at Our Dongguan Plant

    This month our Dongguan high-frequency welding workshop moved a waterproof bicycle frame bag program from sample confirmation into first production. The bag is a full-triangle frame pack built for gravel and bikepacking use: a diamond-ripstop TPU-faced shell, welded gusset, welded hook-and-loop anchor tabs at the top tube, down tube and seat tube, and a water-resistant closure at the top edge. Two closure versions were run side by side during sampling — a zippered version and a roll-top version — because the buyer wanted to see how each behaved under load before locking the tooling.
