Effect of Plasticizer on Oxygen Permeability of Cast

presence of plasticizer. Beyond 5% plasticizer, however, oxygen barrier properties decreased. As expected, OTR and permeability coefficients showed Arrhenius temperature sensitivity. Arrhe-nius parameters were provided in order to permit estimation of OTR or permeability coefficient of cast PLA films at any temperature. 5.0REFERENCES

Abstract. Polylactic acid (PLA) is becoming an increasingly important biopolymer for packaging applications. PLA brittleness limits its applicability. This study evaluated PLA properties with increasing amounts of added polyethylene glycol (PEG) plasticizer. Oxygen transmission rate (OTR) of cast films was determined using the newly available

Effect of Plasticizer on Oxygen Permeability of Cast

Effect of Plasticizer on Oxygen Permeability of Cast Polylactic acid (PLA) Films Determined using Dynamic Accumulation Method setyo purwanto 2014, Journal of Applied Packaging Research Polylactic acid (PLA) is a thermoplastic bio-polyester polymer with properties similar to polystyrenethat is also compostable under commercial composting conditions.

This study evaluated PLA properties with increasing amounts of added polyethylene glycol (PEG) plasticizer. Oxygen transmission rate (OTR) of cast films was determined using the newly available Dynamic Accumulation (DA) method. Arrhenius temperature sensitivity of OTR and polymer Permeability was also determined.

Plasticizer effect on oxygen permeability of beta - PubMed

Abstract Plasticizer effect on oxygen permeability (OP) of beta-lactoglobulin (beta-Lg) films was studied. Propylene glycol (PG), glycerol (Gly), sorbitol (Sor), sucrose (Suc), and polyethylene glycol at MW 200 and 400 (PEG 200 and PEG 400, respectively) were studied due to their differences in composition, shape, and size.

the plasticizing ability of an added plasticizer. A previ-ous study on the effect of plasticizer on a-Lg film mechanical properties showed that plasticizer improved mechanical properties to varying degrees depending on plasticizer type and concentration (Sothornvit and Kro-chta, 2000).

Effect of Plasticizer on Oxygen Permeability of Cast

Permeability of neat PLA is 4.848 ml mm (STP)/m2 s kPa; hence, 4.84 ml mm (STP)/m2 s kPa, 4.07 ml mm (STP)/m2 s kPa and 5.42 ml mm (STP)/m2 s kPa by adding PEG 1 %, 5% and 10% respectively. The main conclusion from this work is increasing PEG will enhance the PLA permeability number but excess PEG in PLA film will decrease the permeability number.
