Are Liners and Labels Included in Thermal Insulated Mailer Pricing?

What the Standard Thermal Mailer Price Covers

The available quotation does not clarify whether extra inner liners or product labels are included. The stated mailer design contains a PE inner film that functions as the sealing layer and can be cleaned by wiping. It also offers a smooth front panel that may remain unprinted for applying labels. When requesting pricing, ask the supplier to identify any included liners, temperature indicators, and batch labels separately.

Construction and Pricing Overview

The standard thermal insulated mailer is a flat, no-gusset pouch made with a metallised reflective outer film, a full-surface 20 mm sponge insulation layer, and a PE inner film. Three sides are heat welded. The opening uses a two-rib zip together with a peel-and-seal adhesive strip.

Based on the product description, the PE film is part of the normal pouch structure rather than a separately listed liner option. However, the available specification does not confirm that an additional protective liner is included in the quoted price. Any supplementary liner should therefore be stated as a separate requirement in the request for quotation.

Label Requirements for Cold-Chain Shipments

The front panel can be produced with an unprinted, flat area for a temperature-monitoring label or a pharmacy batch label. This feature only provides a suitable application area; it does not confirm that the labels themselves are supplied or attached by the manufacturer.

Buyers should confirm whether labels are provided loose, applied during production, or supplied by the buyer. For medicines, chilled foods, perishables, and laboratory samples, the quote should also specify the required label type, dimensions, adhesive performance, and temperature range.

Frequently Asked Questions

Does the quoted structure include a PE inner film?

Yes. The published construction lists PE film as the inner sealing layer. This should not be interpreted as confirmation that a second or specialized liner is included.

Are temperature and batch labels part of the price?

The available information does not include labels in the quoted package. It only states that the front panel can be left blank for label application. Supply and application must be confirmed with the manufacturer.

What should be included in a request for quotation?

Specify the pouch dimensions, material structure, sponge thickness or density, film gauge, printing colors, order quantity, and any requirements for additional liners. Also state whether temperature-monitoring or batch labels must be supplied, printed, or applied.

Conclusion

The described thermal insulated mailer includes a PE inner film as part of its standard construction, but the data does not establish that an additional liner or labels are included in the quoted price. An itemized quotation should distinguish the standard PE layer from any supplementary liner and clearly state whether labels are supplied or applied. The manufacturer reports sample preparation in 3 to 5 working days and production in 15 to 25 days after artwork approval. Technical inquiries can be sent to manager@ecopack.com.
