The available Ecopack product information does not identify the party responsible for return freight when insulated medical bags or related pouches are defective. Buyers should not send products back without first confirming the shipping arrangement. Instead, they should provide photographs of the carton label and the affected units so Ecopack can trace the production batch and determine whether a replacement or credit is appropriate.
The available specification refers to a bone-rib press-seal foil pouch rather than a fully defined insulated medical bag system. Its construction consists of a printed PET exterior, an aluminium-foil barrier layer and a PE inner contact layer. Three edges are sealed, while the remaining edge uses a press-to-close rib closure. A laser score positioned beneath the ribs is intended to make opening easier. Listed pouch dimensions range from 12 × 18 cm to 25 × 35 cm.
Ecopack describes quality checks at several stages, including incoming-material inspection, production monitoring and pre-shipment examination. Finished products are sampled under an AQL process within an ISO 9001:2015 quality management system. Where further verification is necessary, samples may be submitted to a laboratory selected by the buyer.
If the shipping carton is damaged or the delivered batch does not match the approved sample, the buyer should photograph the carton label and the affected units. These details allow Ecopack to identify the relevant production records and investigate the claim. The company states that it will respond within two working days and work with the buyer to determine a replacement or credit.
However, the supplied information does not confirm that defective goods must be returned, nor does it allocate the related freight expense. The buyer should therefore request written instructions about return authorization, carrier selection and payment responsibility before dispatching any goods.

There is no stated allocation of return freight costs for defective insulated medical bags or the described foil pouches.

Huizhou Ecopack Packaging Products Co., Ltd. is a flexible packaging producer based in Guangdong, China. Founded in 2011, the company manufactures customized composite pouches and bags for medical, food and pet-care applications. Its capabilities include product development, printing, lamination, bag conversion and inspection, with exports to more than 40 countries. Ecopack reports ISO 9001:2015 certification for packaging-material production and FSC Chain of Custody certification.
The company also reports supplying a US distributor with 10 million insulated mailers each year for cold-chain shipping. That example highlights reduced heat transfer and lower storage and transport space compared with rigid foam packaging, but it does not establish a policy for freight on defective goods.
