Waterproof Motorcycle Bags — Welded PVC, 40–80L | OEM
Sealock is a waterproof motorcycle bag manufacturer and OEM supplier. Motorcycle luggage faces three hazards that no other bag category deals with: a hot exhaust a few centimetres away, sustained high-speed vibration that loosens everything it touches, and a 50-kilogram load that must not move at highway speed. Rain is almost the easy part. This guide covers what those conditions demand from construction, where soft luggage genuinely wins and where it doesn't, and the range.

Waterproof Bike Bags — RF Welded, IPX6 | OEM, MOQ 200
Sealock is a waterproof bike bag manufacturer and OEM supplier. Cycling attacks a bag in ways that rain alone does not, and it is worth being precise about the mechanisms, because they explain why a bag that performs perfectly on a wet walk starts losing the battle on a wet ride. This guide covers what actually gets water into a bike bag, why mounting position determines the protection a product needs, and the three construction tiers in our range — including an honest account of which one your programme should use.

Recycled Materials for Bags — Claims That Survive EU Rules
Sealock is a waterproof bag manufacturer and OEM supplier, GRS certified. This article is not about why sustainability matters. It is about a date: 27 September 2026, when EU Directive 2024/825 on Empowering Consumers for the Green Transition begins to apply and generic environmental claims stop being a marketing choice and become a compliance exposure. If you sell into the EU and your packaging or listing says "eco-friendly", you have a problem to fix. This guide covers what changes, the trap that catches bag brands specifically, and the evidence chain that makes a recycled claim defensible.

OEM, ODM or Private Label — Which Fits Your Brand
Sealock is a waterproof bag manufacturer working across all three models. The terms get used loosely in this industry — sometimes carelessly, sometimes not — and the difference between them is not academic. It determines who owns the design, whether a competitor can buy the same product, what happens to your tooling if the relationship ends, and how much you spend before the first unit ships. This guide sets out the practical differences, the risk most brands only discover afterwards, and one question specific to welded production that sewn-bag guides never raise.

Tech Pack for a Waterproof Bag — What to Specify
Sealock is a waterproof bag manufacturer and OEM supplier. A tech pack is not a mood board or a sketch — it is the document that lets a factory build your product without guessing, and the quality of it decides whether you approve a sample in two rounds or five. Standard tech pack templates are written for garments and conventional bags, and they are a reasonable starting point. But a welded waterproof bag needs five sections that no garment template contains, and leaving them out is why waterproof projects stall at sampling. This guide covers both layers.

Waterproof Bag Certifications — What Each One Proves
Sealock is a waterproof bag manufacturer and OEM supplier. Most supplier pages list certifications as a row of logos, which tells a buyer almost nothing. Each of these documents answers a different question, several are routinely misread, and one of the most common claims in the industry — "we are BSCI certified" — is not how that scheme works at all. This guide sets out what each certificate actually proves, where the honest mistakes happen, and how to verify any of them, including ours.
