Compare the storage format before choosing the closure

Our reference collection brings together several carrying and access formats. Use the individual product page to identify the pictured construction and supplied specifications. The collection name is not a shared immersion, pressure or depth rating for every compartment and model.

Specify the complete airtight bag assembly

For buyers comparing an airtight waterproof bag manufacturer or supplier, the specification should identify the material, seams, closure and fittings as one assembly. A shell swatch cannot demonstrate the retention performance of an installed zipper or valve. External pockets and stitched carry parts may have different functions from the main storage compartment.

Assembly elementWhat to specifyWhat to review
Material buildBase textile, coating or laminate, thickness and finish.Material identity and flexibility at the closure and seam transitions.
Seams and junctionsPanel layout, weld paths and reinforcement locations.Straight seams, corners and multi-layer transitions.
Main closureExact component, installation, operating sequence and end construction.Opening access, closure operation and surrounding joints.
Valve where includedPurpose, placement, interface and cap arrangement.Operation and the fitting-to-shell interface.
Carrying systemIntended packed load, handles, straps and adjustment.Access and fit on the loaded sample.

Use the materials and construction overview to prepare the technical brief. Define any required air-retention evaluation and water-exposure evaluation separately, including the method and acceptance criteria for the supplied design.

Separate air retention, water exposure and carrying checks

A useful sample plan states exactly what is being assessed. Record the sample ID, material and drawing revisions, closure state and fittings. Agree the conditions and permitted outcome before an evaluation is carried out; retain observations and photographs with the result.

EvaluationInformation to agreeResult applies to
Air retentionMethod, pressure where applicable, duration, conditions and permitted change.The tested assembly and configuration.

If your sourcing brief uses “submersible backpack”, state the intended exposure and evidence needed. An airtight description or a component claim does not establish a depth rating. Discuss applicable testing and certification documents with our team for the exact model and destination market.

Custom airtight waterproof bags for your collection

Mark the changes you need on a product reference or drawing. For OEM airtight waterproof bags, review the effect of changes to material, closure length, valve placement, pocket layout and carrying attachments. A change at a protected-compartment interface needs more than an exterior colour approval.

  • Separate structural revisions from colour, logo and label changes in the enquiry.
  • Confirm the branding method and position on the selected material.
  • Include instructions for the actual closure and any model-specific care requirements.
  • Keep the approved sample, component references and packing sheet available for repeat wholesale orders.

For wholesale airtight waterproof bags, quote each model and configuration clearly. Review the factory evaluation checklist for a structured sample and documentation review.
