How Dry Bags Are Tested Before Shipment
Sealock is a dry bag manufacturer and OEM supplier. Every factory says its bags are tested. The question that separates suppliers is a narrower one: tested how, on which units, and can you see the record? A dry bag is a single welded chamber with no lining to hide a weak seam, so testing is both easier to do honestly and easier to fake convincingly. This guide sets out the full inspection sequence a dry bag order passes through — from incoming rolls to the container door — and the questions a buyer should ask at each stage.

Dry Bag Capacity Guide for Wholesale Buyers
Sealock is a dry bag manufacturer and wholesale supplier. For a distributor, capacity is not a technical question — it's an inventory decision. Dry bags are one of the few outdoor products sold almost purely on litres, which means the sizes you stock determine your sell-through, how much cash sits in slow rungs of the ladder, and whether a customer finds the bag they came in for. This guide covers which capacities actually move, how deep to go on each, and the packing and labelling details that catch wholesale buyers out.

Roll Top Dry Bag vs Waterproof Zipper Dry Bag
Sealock is a dry bag manufacturer and OEM supplier. Ask around the paddling world and you'll get two confident and apparently contradictory answers: that a roll-top is the most reliable seal there is, and that only a proper waterproof zipper is genuinely submersible. Both are right, because they're measuring different things — one is talking about failure rate in the field, the other about sealing performance under sustained pressure. Our standard dry bag range is built around the roll-top, which is the right closure for the great majority of dry bag use; a waterproof zipper is available as a custom closure where a project genuinely calls for it. This guide separates the two so a brand can specify the closure its customers actually need.

Dry Bag Material Guide: TPU vs PVC
Sealock is a dry bag manufacturer and OEM supplier building in both TPU and PVC. The useful question in this comparison is not which material is better in the abstract — it's which performs better under the conditions a dry bag actually faces: rolled and unrolled several times a day, dragged across rock, left in a hot boat, packed away creased for a season, and expected to seal on the first attempt with cold hands. That framing gives clearer answers than a generic spec sheet, and it changes which material wins depending on the product.

Sprievodca výrobou suchých vrecúšok na mieru
Sealock je vlastný výrobca suchých vreciek a dodávateľ OEM. Väčšina sprievodcov pri získavaní zdrojov sa zastaví pri materiáloch a minimách. Toto sa dostane do továrne, pretože na suchom vreci je výrobná postupnosť produktom: zváraná rúrka nemá podšívku, ktorá by zakryla slabý šev, ani zips, ktorý by sme mohli obviňovať, takže každé rozhodnutie o tolerancii rezu, parametroch zvaru a vykonaných objednávkových operáciách sa priamo prejaví v tom, či hotová taška obsahuje vodu. Pochopenie tejto postupnosti povie kupujúcemu, čo má špecifikovať, čo má vidieť, a kde sú skutočné obmedzenia vlastného dizajnu.

OEM továreň na suché vrecia pre outdoorové značky
Sealock je továreň na suché vrecia OEM v Číne, ktorá dodáva outdoorové značky, značky paddlesports a veľkoobchodných odberateľov po celom svete. Outdoorová značka málokedy potrebuje jednu suchú tašku – potrebuje rad: malý vak na telefón a peňaženku, stredný vak na deň vo vode, veľký na víkend a zvyčajne batohovú verziu na prechádzku. Na to, aby táto línia vyzerala a fungovala ako rodina, na jednom vodotesnom štandarde, je továreň na zváranie. Táto príručka popisuje, ako zostaviť sortiment suchých vriec, kde sa odlíšiť a ako to podporuje výrobná strana.
