For seasonal insulated lunch bags, start arranging shipping while the artwork is under review. Once the design and specifications are approved, allow 15 to 25 days for production, then add the transit time for the chosen shipping service. Sea freight needs the most lead time; rail delivery to Europe typically takes 18 to 22 days, air freight takes around 5 to 7 working days door-to-door, and express courier usually takes 3 to 5 business days.
\nSeasonal orders have two main lead-time stages: manufacturing and transport. Samples generally take 3 to 5 working days, while standard production takes 15 to 25 days after artwork approval. Because sign-off starts the production schedule, finalize the bag specification before confirming a delivery plan.
\nA square-bottom insulated lunch bag can be made with an aluminium foil laminate exterior, 2-5 mm closed-cell EPE foam, and a food-grade PE inner contact layer. Side gussets and a folded base panel form the square bottom, with base depths available in 10, 12, or 15 cm. Standard size options range from 30 x 35 x 10 cm to 45 x 50 x 15 cm, and custom Pantone printing can be applied to the front, back, and both side gussets.
\nFor takeaway and food-delivery programs, a firm, flat base helps keep containers level in transit. Grocery and cold-chain applications may call for a gel-pack sleeve and a waterproof inner membrane. Since these choices can affect the finished product, settle the dimensions, insulation core, closure, and artwork before production and freight are booked.

| Transport option | Typical use and scheduling notes |
|---|---|
| Sea Freight (FCL) | A practical choice for larger production runs and full-container loads. Typical transit is 14 to 18 days to the US West Coast, 30 to 35 days to Europe, and 12 to 16 days to Australia, not including clearance. |
| Sea Freight (LCL) | Suitable for smaller or initial orders that do not fill a container. Consolidation can add about 5 to 10 days to ocean transit, and the cartons may be handled more often. |
| Air Freight | Useful when the launch date matters more than the freight cost. Airport-to-airport transit is usually 2 to 4 days to the US and Europe; door-to-door delivery is around 5 to 7 working days. |
| Express Courier | Best suited to samples, proofs, and small time-sensitive parcels. DHL, FedEx, and UPS typically deliver door-to-door to the US, Europe, and Australia in 3 to 5 business days. |
| Rail Freight to Europe | An intermediate option for mid-size European shipments, with typical door-to-door transit of 18 to 22 days. |
