Abstract

Moisture-absorbing film impregnated with synthesized attapulgite with acrylamide (ATPGAA) was developed. The effects of ATPGAA concentrations of 0.5%, 1%, 2%, and 4% (w/w) in a linear low-density polyethylene polymer (LLDPE) matrix on the film properties were determined by measuring the physical properties, the oxygen and water vapor barriers, and moisture absorbency. The 4% ATPGAA film had high moisture absorbing efficiency. A packaging system fabricated from ATPGAA-impregnated films was applied to a dried-seasoned laver to evaluate its change in quality during storage. Seasoned laver packaged with ATPGAA-impregnated films had significantly greater crispness in texture and a lower peroxide value during storage than that packed with LLDPE film. The surface color of the seasoned laver packaged by ATPGAA-impregnated films was more stable than the control film. This study shows that moisture-absorbing films could serve as a packaging system to improve the storage quality of moisture-sensitive products.
