  • Motorcycle Saddlebag Manufacturer for Adventure Motorcycle Brands

    Sealock manufactures motorcycle saddlebags and soft panniers for adventure brands and OEM programmes from factories in China and Vietnam. Saddlebags are the most demanding position in motorcycle luggage to engineer, because a bag hanging beside the rear wheel sits close to a hot exhaust, close to a spinning tyre, and on a machine whose handling depends on the two sides being balanced. Tail bags forgive a loose specification; saddlebags do not. This covers what an adventure brand has to get right.

  • 25L Waterproof Backpack: Ideal Capacity for Day Hiking and Travel

    Sealock manufactures the 25L waterproof backpack for wholesale and OEM buyers worldwide, and 25 liters is the size most buyers come back to — large enough for a full day on the trail, small enough to carry on a plane. It hits the point where a pack stops being a compromise between "too small to be useful" and "too big to carry comfortably." The sections below set out why the capacity works, what it holds, and how it performs for both day hiking and travel.

  • The Science of Cold-Flex Durability: 1000D Ballistic TPU and Seam Integrity in Sub-Zero Scenarios

    Written exclusively for tactical Search and Rescue (SAR) and extreme maritime procurement directors, this technical brief dissects the underlying polymer degradation and interfacial failure mechanisms of 1000D Ballistic TPU dry bags deployed in sub-zero environments. Bypassing commercial marketing narratives, it utilizes rigid process-tolerance language to evaluate the glass transition temperature (Tg) variations between polyester-based and polyether-based TPU coatings. The analysis isolates critical stress concentrations at high-frequency weld edge transitions caused by minute pneumatic pressure shifts across brass dies, providing an actionable factory audit playbook backed by ASTM G154 accelerated weathering and low-temperature flex validation metrics.

  • ​Is a dry bag the same as a waterproof bag?

    While "dry bag" and "waterproof bag" are often used interchangeably in casual conversation, they can refer to slightly different products or serve different purposes depending on context.

  • Dry Bag MOQ Explained: Minimum Order Quantities for OEM Projects

    Sealock is a dry bag manufacturer running OEM and wholesale projects at an MOQ of 300 pieces, and the minimum order quantity is the number that surprises the most first-time buyers. MOQ is not a barrier a factory invents to exclude small brands — it is a calculation tied to material sourcing and production economics, and understanding what drives it is exactly what lets a buyer negotiate it intelligently rather than just asking for a lower number. This explains why dry bag MOQs land where they do, what moves them, and how to work with them on an OEM project.

  • Notes on the use of backpacks

    Always let your bag see the sun, don't keep it indoors without outdoor sports. Without the nourishment of sunlight, your bag may become moldy, and there will be some peculiar smell, which makes people feel very uncomfortable, not to mention that you have to carry it on your back. So, why not take out your bag for a sunbath every once in a while and give it some sunshine?
