Development of Composite Film for Improving Gas Permeable Properties

Article Preview

Generally, a suitable polymer for using as pH indicator packaging should exhibit high porosity to provide a maximum gas permeability which lead to an accurate detection. Ethylene vinyl acetate (EVA) is normally used as such application. However, the gas permeability of EVA was fairly low as 1685.0940 cc/ (m2-day) which not good enough for used as pH indicator packaging application is. To increase a permeability of gas, high porous diatom incorporating with biopolymer was mixed into EVA polymer via internal mixer. It was found that the gas permeability of EVA filled porous diatom/biopolymer was increased up to 4204.2225 cc/ (m2-day). This property is one of the crucial properties for further design for pH indicator packaging in NHAM product.
