Insulated Mailer Lead Times for Cold Shipping: What to Expect

For custom insulated mailers used in cold shipping, allow 15 to 25 days for production after the artwork has been approved. Sample preparation typically takes 3 to 5 working days. Because production scheduling begins only after approval, confirming the design promptly is key to keeping the order on track.

Lead Time at a Glance

Product Design and Ordering Details

The mailer ships flat, with units packed and counted by carton. Standard dimensions are 20 × 28, 25 × 33, 30 × 39 and 35 × 45 cm, and other sizes can be made to order. Buyers can also specify film thickness, foam density, the placement of the adhesive band and print requirements. Front-panel flexographic printing is available in one or two colours.

For an accurate quotation, share the requested size, film structure, print colours and expected order quantity. Providing customization details at the same time can help clarify the specification before artwork is prepared and approved.

Cold-Chain Use

These insulated mailers are intended for shipping medicine, food and other perishable goods, and product information specifies use with an ice pack. For pharmacy deliveries and 2–8°C cold-chain applications, the company also describes using an insulated mailer or bag with a dedicated gel-pack sleeve. A flat, unprinted window can be included for monitoring and batch labels.

These options describe possible configurations, not a guaranteed holding time or temperature performance. Confirm that the packaging setup is appropriate for the product, route and cold-chain requirements before shipment.
