Customer Case Study

We partnered with a US health food manufacturer specializing in freeze-dried fruit and vegetable snacks. Their products were troubled by moisture absorption and short shelf life using ordinary kraft bags. Our kraft paper PE laminated composite bags solved this problem. The paper outer layer delivered premium natural texture for retail shelves, while the inner PE film provided reliable moisture and oxygen barrier. After bulk deployment, the shelf life of their freeze-dried products was greatly improved, product return rate decreased, and their natural healthy brand positioning was enhanced. The US customer praised our stable composite lamination quality and consistent mass production delivery.
