Applicable requirements depend on the finished product, intended use, claims, destination market, and responsible economic operator. Cryozin can review project-specific documents that are available for the proposed configuration, but certificates, FDA registration or listing information, CE documentation, SDS, REACH, and RoHS records have different scopes and must be matched to the relevant product, material, entity, site, and market. Registration or listing does not represent FDA product approval.
Material and safety documentation depends on the exact gel, film, ink, textile, intended contact, and destination market. Cryozin can review applicable SDS, material declarations, and project-specific test records where available. Leakage risk should be controlled through agreed seal, integrity, conditioning, sampling, and handling criteria; no reusable pouch is immune to every puncture, cut, overload, or aging condition.
Flexibility depends on gel formula, fill ratio, film, storage temperature, and conditioning time. Some formulations can be evaluated for soft-freeze behavior, but the finished product should be approved under agreed test conditions rather than a universal temperature or therapeutic-performance claim.
Yes, we are a direct factory with strong R&D capabilities. We provide full OEM and ODM services. For a broader overview, visit Cryozin’s ice pack manufacturer homepage. For program scope and private-label development, review our OEM ice pack program. You can customize:
- Product: Shapes, sizes, fabric materials (e.g., plush backing, non-woven fabric), gel colors, and formulations.
- Branding: Silk-screen printing, debossed logos, or custom fabric labels.
- Packaging: Color boxes, zipper bags, frosted bags, or PDQ display boxes suitable for retail.
MOQ depends on the product and printing configuration. Standard products start at 500 without printing or 1,000 per design with printing. Pet Cooling Mats & Pads and PCM Cooling Vests remain at 300. Confirm the quantity and sales unit for the selected configuration. Underwear and breast-pad products are counted by set; confirm each set's contents.
Share the product, size, artwork and packaging requirements so the quotation can apply the correct order scope.
Yes. Product renderings are typically prepared in 1–3 business days, and samples in 3–7 business days. The exact sample scope and schedule are confirmed for the project before work begins.
Standard products typically require 18–25 business days. Customized products require additional time, with the final schedule confirmed for the approved specification and order scope.
If a pack leaks, provide photos or video and the order details. After the issue is verified, replacement supply can be arranged. Agree the reporting period, quantities, freight and other remedies in the purchase terms.
Cryozin develops reusable hot and cold pack formats for several B2B product programs:
- Beauty & Personal Care: eye and face masks, cushions, and other brand-specific formats.
- Healthcare & Postoperative Programs: body-area packs and wraps whose intended use, evidence, labeling, and regulatory pathway must be confirmed for the finished product.
- Sports & Outdoors: reusable packs, wraps, cooler formats, and PCM wearables selected against fit and temperature-management requirements.
- Maternity and Children’s Formats: body-specific or shaped packs requiring careful review of intended users, materials, instructions, warnings, and applicable market rules.
Absolutely. We deeply respect intellectual property. We are fully willing to sign a strict NDA before you share any proprietary designs, custom shapes, or branding artwork with us. Your customized products will remain strictly confidential and will never be displayed in our public catalog, exhibited at trade shows, or sold to other clients.
Yes, we work with professional freight forwarders who specialize in international logistics. We offer flexible trade terms including FOB, CIF, EXW, and DDP (Delivered Duty Paid). If you choose DDP, we handle all customs clearance and duties, delivering goods directly to your Amazon FBA warehouse or private business address across the US and Europe.
Since gel packs are heavy, we use reinforced, export-standard 5-layer corrugated master cartons. If required, we also provide palletization services to ensure the cargo remains intact and moisture-free during long-distance ocean or air freight.
Welcome! We transparency. We welcome third-party inspections (such as SGS, BV, or Intertek) prior to shipment. We also support virtual live factory tours via video calls (Zoom/Teams) if you cannot visit China in person.
Payment terms are confirmed in the quotation and purchase agreement. Confirm the contracting and payment entities, currency and payment schedule for the order before making a payment.
Standard gel and gel-bead packs use different filling structures and should be compared against the intended product format:
- Standard Gel Packs: Evaluate fill ratio, conditioned flexibility, temperature profile, film or laminate, seal design, dimensions, and use instructions.
- Gel-Bead Packs: Evaluate bead distribution, visual appearance, conditioned feel, chamber design, outer material, and compatibility with the selected face, eye, or wearable format.
The better choice depends on the approved product specification, target user, claims, test conditions, packaging, and cost—not on a universal performance assumption.
There is no universal shelf life for every hot and cold pack. It depends on the gel or PCM, film or laminate, seals, manufacturing controls, packaging, storage conditions, preparation method, and acceptance criteria. Buyers should request a project-specific shelf-life basis and storage instructions for the approved configuration rather than relying on a generic duration.
We review available capacity and scheduling for each project based on the product specification, order quantity and requested delivery date. Share your seasonal plan early so we can assess the production options before committing to a schedule.
Packaging options with recycled, certified, reduced-material, or alternative components can be discussed for a specific project. Any environmental claim should identify the exact material, percentage, certification scope, supplier evidence, disposal context, and destination-market rules. FSC, recycled-content, recyclability, biodegradability, and reuse claims are not interchangeable and should be verified before artwork is approved.
Yes, we understand the fast-paced nature of e-commerce. In addition to manufacturing, we can support your marketing and operations by providing:
- FBA Prep Services: FNSKU barcode labeling, warning stickers, and polybagging strictly following Amazon's requirements.
- Marketing Assets: We can assist with providing high-resolution product images and realistic promotional materials to help you launch your listings faster.
- Packaging Design: Suggestions for retail-ready packaging that optimizes shipping dimensions and reduces your freight costs.
