Characteristics and performance of film

The material immersed in LLDPE film is a synthetic compound of cross-linked polyacrylate and attapulgite-acrylamide and featured moisture absorption capability more than 3 times greater than the traditional dessicant(or moisture absorbing material in moisture absorbency testing under various humidity conditions. Both substances are classified as superabsorbent that absorb over 500 times the substance weight upon contact with liquid. In addition, various data have verified that these substances are harmless to the human body. Both substances have been physically mixed through the LLDPE extrusion process and although mechanical degradation was revealed as a result of substance mixture, this can be improved with a compound film in real practice and there was no change due to substance mixture in terms of thermal properties. The research on product quality changes when developed films are being applied to dried foods (Seasoned laver in the market) was performed by comparing with the seasoned laver product using the traditional moisture-absorbing agent and the product quality is similar and product quality deterioration is rarely observed. Also, it exhibits higher product quality compared to seasoned laver products without moisture-absorbing agent.

moisture absorbing ability evaluation by moisture absorbing materials

moisture absorbing ability about 4 times greater than the standard moisture absorbing materials (Silica gel)

Applicable areas

It can be used for seasoned laver and other various dried foods including dried meat, and flour that are sensitive to moisture to maintain product quality.
Also, it can be used for electronics that are sensitive to even slight moisture such as semiconductors and displays and for military supplies that are stored in storage for long periods of time.
