Development of biodegradable flexible films of starch and poly(lactic
Biodegradable films were produced from blends contained a high amount of thermoplastic starch (TPS) and poly (lactic acid) (PLA) plasticized with different adipate or citrate esters. It was not possible to obtain pellets for the production of films using only glycerol as a plasticizer.
Structure evolution of polyethylene-plasticizer film at industrially
Structure evolution of slightly oriented high density polyethylene (HDPE)-plasticizer film is recorded with small- and wide- angle X-ray scattering (SAXS/WAXS) during stretching. The HDPE has number average molecular weight (M n) of 300 kg/mol and polydispersity index (M w /M n) of 20, respectively.
Comparative Effect of Different Plasticizers on Barrier
Purpose Identifying ideal plasticizer is pivotal to develop a biopolymer-based edible films for food packaging. The effect of different plasticizers (glycerol, polyethylene glycol, sorbitol) on the mechanical, water vapor barrier, optical, and moisture sorption properties of hydroxypropyl methylcellulose (HPMC) -based flexible films was examined in this study.

film forming temperature; it is the minimum temperature above the T g of the polymer. In order to ensure the optimum conditions for film formation, the really used coating temperature during the application process should be 10-20 °C above the minimum film forming temperature (Lehmann, 1992). Since plasticizer addition to film coating

while the lowest yield at 0.5%, which was 0.09 mm. With the concentration of polymer and polyethylene glycol (PEG) plasticizer keep increasing, it causes an increase in film thickness. Polyethylene glycol plasticizer has properties that are easily soluble in water and can increase the viscosity of the solution (Gorle et al., 2015).
