  • Tagging, Surface Protection and Multi-Model Control on a Welded Backpack Order

    There is a gap between a bag being made and a bag being ready to sit on a shelf, and most of the cost of getting that gap wrong lands on the brand rather than on the factory. This month our Dongguan finishing floor ran a black welded roll-top backpack and duffel program through that gap in full: hangtag application, barcode labelling, zipper-pull and hardware protection, surface cleaning, model separation and pack-out — with a high-visibility order running on the adjacent benches at the same time.

  • Fishing Bag Supplier Selection Guide

    Sealock is a waterproof fishing bag supplier and OEM manufacturer serving tackle brands, distributors, and retail buyers from factories in China and Vietnam. Vetting a supplier in this category has one question at its centre that no other outdoor category shares: saltwater destroys zippers, and experienced anglers openly say that a zipper exposed to salt will eventually fail regardless of care. How a supplier answers that determines whether its product survives a second season — and it is the fastest way to separate a real fishing manufacturer from a general bag factory.

  • Motorcycle Waterproof Bag Supplier Selection Guide

    Sealock is a motorcycle waterproof bag supplier and OEM manufacturer serving distributors, dealer networks, and adventure brands from factories in China and Vietnam. Vetting a supplier in this category is not the same exercise as vetting a general bag factory. Motorcycle luggage is mounted to a vibrating machine, sits near an exhaust, carries a rated load, and — uniquely in the waterproof range — carries a legal exposure most buyers never think to check. This is the verification sequence worth running before a purchase order.

  • How a High-Visibility Roll-Top Dry Bag Order Gets Sewn, Checked and Boxed

    Most factory photography stops at the welding machine, because that is the part that looks like manufacturing. The part that actually decides whether a container arrives clean is the last three metres of the line — the sewing benches, the finishing tables, the count cards, the poly bags and the carton. This month our Dongguan plant ran a high-visibility roll-top dry bag order through exactly that stretch, and it is worth walking through in detail, because the questions buyers ask us after a bad experience with another supplier are almost always about this stage rather than about seam fusion.

  • Common outdoor food preservation methods

    Food is precious to you when you're living outdoors. Don't feed animals with your food. Because you will starve. Here are some common ways to store food outdoors.

  • Vietnam or China: Choosing a Waterproof Bag Manufacturing Base in 2026

    Sealock manufactures waterproof bags for OEM and wholesale buyers from factories in Dongguan, China and Ho Chi Minh City, Vietnam, with either origin available on any model in the range. For importers, the origin decision changed twice in 2026 and most sourcing advice online is now out of date — including the widely repeated claim that Vietnam is duty-free. This sets out what actually applies, how to calculate it for bags, and what determines origin when a supplier operates in both countries.
