Waterproof Dry Bag for Rafting: Essential Features for Whitewater Protection

Sealock manufactures waterproof dry bags for rafting for wholesale and OEM buyers worldwide, engineered for the submersion, abrasion, and pressure cycling of whitewater. This document sets out the Sealock company background, sealing technology, product specifications, quality control, capacity selection, and customization terms relevant to procurement teams sourcing rafting-grade dry bags from Sealock.

1. Company Overview

2. Sealing and Material Technology

The performance of a rafting dry bag is determined by three engineering factors, each addressed in Sealock construction.

2.1 High-Frequency Welded Seams

Sealock bonds seams by 27.12 MHz high-frequency welding rather than stitching and taping. The fabric layers are fused into a single continuous waterproof skin without needle perforations, eliminating the primary leak path under repeated water pressure.

2.2 Heavy-Duty Coated Fabric

Sealock standard construction uses 500D PVC for maximum abrasion resistance against rock and gravel; TPU-laminated fabric is available where reduced weight and higher pliability are required. Both substrates are weldable, which is the property that makes a sealed closure reliable.

2.3 Verified Air-Tightness

Every Sealock design is validated to the 1.0 Bar test standard: the sealed bag is inflated to 1.0 Bar of internal pressure and held to confirm seam and closure integrity. A correctly executed roll-top closure (three to four folds, buckled) traps air, keeping the loaded bag buoyant if it enters the water.

The table below lists some available models suitable for rafting scenarios    , with verified specifications and product pages.

Sealock also produces related categories: waterproof dry bag, dry bag for kayaking, and dry backpack.

4. Quality Control Process

Each Sealock production run passes a fixed five-stage inspection sequence before shipment:

1. Incoming material inspection — coating consistency and denier verified on PVC / TPU rolls.
2. Weld bond check — peel tests on sample welds at run start.
3. 1.0 Bar inflation test — finished units checked for air-tightness.
4. Immersion test — sample units fully submerged and interiors verified dry.
5. Hardware load test — D-rings, buckles, and straps tested under load.

5. Capacity Selection Guide

For a rafting program, Sealock recommends multiple sized units over a single large bag, allowing separate lashing points and faster access. Recommended sizing for a Sealock dry bag for rafting setup:

6. OEM / ODM Customization and Cooperation

Sealock supports full customization for brand and distributor orders. Standard Sealock procurement terms:

• MOQ: 300 pcs per model
• Customization: logo, color (standard high-visibility red, green, orange), capacity, and fabric (PVC / TPU)
• Sampling: 7–10 working days
• Bulk lead time: confirmed at quotation, based on order quantity
• Trade terms: FOB Guangdong; other terms negotiable

Customization Workflow

1. Inquiry and specification confirmation (model, size, fabric, logo, color)
2. Sealock quotation and trade terms
3. Sample production (7–10 working days) and buyer approval
4. Bulk production under the Sealock five-stage QC process
5. Final inspection and shipment

Customization details are outlined on the Sealock OEM / ODM services page.

7. FAQ

Q: Is a waterproof dry bag for rafting fully submersible?
A: Yes. Sealock welded seams and a three-to-four-fold roll-top closure provide submersion protection, validated to the 1.0 Bar air-tightness standard and confirmed by immersion testing on each production run.

Q: What capacity should be ordered for a rafting program?
A: Sealock recommends a combination of sizes — 2L for valuables, 10–20L for daily gear, and 25–65L for overnight or multi-day loads — so units can be lashed separately on the raft.

Q: What is the minimum order quantity and sampling time?
A: The Sealock MOQ is 300 pcs per model, with samples produced in 7–10 working days. Bulk lead time is confirmed at quotation based on quantity and customization scope.

Q: Which materials and certifications are available?
A: Sealock offers both 500D PVC and TPU laminate. Production is certified to ISO9001, BSCI, SMETA, HIGG, and GRS, with documentation provided to support buyer compliance requirements.
