Large 38 × 29 cm Nylon Gel Pack

Large rectangular gel-pack format for broad coverage requirements

This product is presented as a large textile-covered rectangular pack with a target size of 38 × 29 cm. The broad format is a practical sourcing distinction from compact and elongated packs, but the exact dimensions, construction, filling, unit count, conditioning instructions and use limits must be approved against the physical sample. No medical result, safety grade or temperature duration is implied.

Buyer facts and open specifications

Large-format sample checklist

• Measure the full pouch, filled area, seams, thickness, fill weight and overall weight.
• Review fill distribution, fold behavior and handling across the intended placement area.
• Confirm outer layers, filling, closures and any sleeve, strap or accessory.
• Define conditioning steps, limits, application intervals, warnings, cleaning and storage.
• Agree applicable seam, leakage, drop, conditioned-flexibility and repeated-use checks.
• Confirm image ownership and photograph the exact approved model and packaging.

OEM decisions before quotation

Share the intended market, channel, quantity, placement requirement, dimensions, material direction, branding, instructions and packaging. Size, construction, filling, color, logo and packaging can be reviewed as project options; feasibility and commercial terms follow the approved configuration.

Use the customization process to organize the brief and the material selection guide to discuss construction choices.

Quality and documentation scope

The approved sample and specification can define checkpoints for dimensions, weight, fill distribution, seams, the agreed leakage method, conditioned flexibility, artwork, labels, instructions and packaging. Documentation availability depends on the exact material, intended use, market and agreed scope.

See the quality-control process for how project requirements become inspection points.

Frequently asked sourcing questions

Is 38 × 29 cm a verified production dimension?

Confirm it with a drawing and measured production-intent sample before publishing a final tolerance.

What makes this page distinct from smaller packs?

The defensible distinction is the verified large physical format and compatible packaging, not duplicated relief or performance claims.

Can the current ZEJIN images be used?

Only after product identity, brand ownership and image-use rights are confirmed for Cryozin’s offer.

How long does it remain cold or warm?

No duration should be stated without a target band, conditioning method, environment, sample identity and applicable report.
