  • TPU Waterproof Duffel Bags: Performance Advantages

    Sealock manufactures TPU waterproof duffel bags for OEM and wholesale buyers from factories in China and Vietnam. TPU has become the default material for premium waterproof duffels, but the reason is not a single headline property — it is that TPU delivers an unusual combination at once: it stretches without tearing, stays pliable in freezing conditions, resists abrasion, and bonds cleanly under RF welding. This sets out how each of those behaves specifically on a duffel, and the one material distinction most buyers never ask about.

  • Heavy Duty Waterproof Duffel Bags for Commercial Use

    Sealock manufactures heavy duty waterproof duffel bags for commercial fleets, marine operators, outfitters, and institutional buyers from factories in China and Vietnam. Buying duffels for an organisation is a different exercise from buying them for a store. The unit price matters less than the replacement cycle, the specification has to hold across every bag issued, and a failure in the field is an operational problem rather than a return. This sets out what "heavy duty" has to mean at commercial grade, and what a fleet specification should contain.

  • Waterproof Bicycle Tail Bag: A New Focus in the Outdoor Cycling Gear Market

    Amid the continued rise in popularity of outdoor cycling, the waterproof bicycle tail bag has become a core growth driver in the cycling gear sector due to its functionality and practicality. According to the latest "2025-2030 Cycling Gear Industry Trends Report" released by a global outdoor products market research institution, the waterproof tail bag market is projected to expand at an average annual growth rate of 12.7% over the next five years, with the Asia-Pacific region becoming the largest growth market globally due to the popularization of cycling culture and surging demand for urban commuting.

  • Waterproof Bike Bag Supplier from China

    Sealock is a waterproof bike bag supplier and OEM manufacturer serving cycling brands, bikepacking labels, and distributors from factories in China and Vietnam. Sourcing bike luggage carries a risk no other bag category has: a bag can be flawlessly manufactured — perfect welds, clean stitching, correct materials — and still be a total loss, because it does not fit the bike. Fit is the failure mode here, and it is what supplier vetting in this category has to be built around.
