Custom Dry Bag Production Guide
Sealock is a custom dry bag manufacturer and OEM supplier. Most sourcing guides stop at materials and minimums. This one goes onto the factory floor, because on a dry bag the production sequence is the product: a welded tube has no lining to hide a weak seam and no zipper to blame, so every decision about cutting tolerance, weld parameters, and the order operations run in shows up directly in whether the finished bag holds water. Understanding that sequence tells a buyer what to specify, what to ask to see, and where the real constraints on a custom design sit.

OEM Dry Bag Factory for Outdoor Brands
Sealock is an OEM dry bag factory in China supplying outdoor brands, paddlesports labels, and wholesale buyers worldwide. An outdoor brand rarely needs one dry bag — it needs a line: a small sack for a phone and wallet, a mid-size for a day on the water, a large one for a weekend, and usually a backpack version for the walk in. Building that line so it looks and performs like a family, at one waterproof standard, is what a welding factory is for. This guide covers how to structure a dry bag range, where to differentiate, and how the manufacturing side supports it.

Welded Dry Bags 2–100L — MOQ 200, CN & VN Origin | OEM Factory
Sealock is a dry bag manufacturer in China supplying OEM, ODM, and wholesale buyers worldwide. The dry bag is the oldest and simplest product in waterproof gear — a single welded chamber closed by rolling the top — and it remains the benchmark by which a waterproof factory is judged. There is nowhere to hide: no lining to disguise a bad seam, no zipper to blame. Either the welds hold and the closure seals, or the customer's sleeping bag comes out wet. This overview covers how a dry bag is built properly, what actually causes the failures buyers hear about, and the sourcing terms.

Waterproof Phone Pouch Material Guide for Buyers
Sealock is a waterproof phone pouch manufacturer and OEM supplier. A phone pouch is not made of one material — it's a body film, a transparent window, a gasket, and lock hardware, and each is chosen separately. Buyers usually ask "PVC or TPU?" as if that settles it, when the questions that actually decide the outcome are film thickness, clarity retention, gasket elasticity, and compliance. This guide covers each component, what the real trade-offs are, and where the commercial risk sits.

How Waterproof Phone Pouches Are Tested
Sealock is a waterproof phone pouch manufacturer and OEM supplier. Every pouch on the market is described as waterproof; far fewer have been tested in a way that means anything. The gap matters more here than in any other waterproof product, because the customer isn't risking a wet towel — they're risking their phone. This guide walks through how a phone pouch is actually tested, from the international standard behind the rating to the checks on the production line, the final shipment inspection, and the three-minute test a buyer can run themselves.

IPX8 Waterproof Phone Pouch Manufacturing Guide
Sealock is an IPX8 waterproof phone pouch manufacturer and OEM supplier. IPX8 is the highest water-ingress class in common use, and on a phone pouch it carries a weight no other product does: the pouch guards a device worth many times its own price, and a single pinhole destroys it. This guide explains what IPX8 actually demands, the sealing architectures that reach it, and the manufacturing discipline that makes the rating repeatable across a hundred thousand units rather than true of one good sample.
