Cold Shipping Boxes and Insulated Liners for Food and Perishable Shipping
Coldkeepers Customer Offer
Use code KEEPCOLD10 for 10% off your first purchase of liner-compatible cube shipping boxes. If insulated liners are already a meaningful part of your per-box cost, upgrading to a custom outer box in kraft, 200# kraft, or white can be an easy way to improve presentation, branding, and consistency.

How It Works
QR Codes Are a Strong Fit for Cold Shipping
Cold-chain shipments are a strong use case for QR-enabled packaging because customers are already interacting with the box at an important moment. A printed QR code can help extend the value of the shipment after delivery.
Drive subscriptions and reorders
Send customers directly to a subscription offer, reorder page, or a focused next-step landing page.
Share product education
Use the box to deliver handling information, prep tips, sourcing details, recipes, or care instructions.
Keep it simple
Put the code where it is easy to find, give customers a clear reason to scan, and link to one focused destination instead of too many choices.
