As a biodegradable and flexible copolymer, poly(butyleneadipate-co-terephthalate) (PBAT) is used for packaging. However, high cost limited properties restrict its applications. Because of the hydrophobic nature PBAT, low mechanical are observed when PBAT cellulosic fibers, which hydrophilic, in blends. To increase interfacial adhesion between cellulose γ-(2,3-epoxypropoxy) propytrimethoxysilane...

Poor water-vapor barriers and mechanical properties are common problems of biobased films. To maintain food quality, the barrier its strength performance need to be improved. Tea polyphenols (TP) a natural active substance, their benzene ring structure provides for them as film material. Films that incorporate TP also have enriched functionalities, e.g., antioxidants. Here, poly (vinyl alcohol)...

Edible and/or biodegradable films usually have limited water vapor barriers, making it difficult to use them. Thus, the objective of this work was to evaluate the effect of a chemical reticulation treatment with formaldehyde and glyoxal on the mechanical properties, water vapor permeability, solubility and color parameters of gelatin-based films. Formaldehyde and glyoxal were added to the filmo...

a suitable option for manufacture of packing materials is the use of clay and silver nano particles. these materials help create optimal relative impermeable quality, in addition to other features being improved. moisture-packed bread by use of these materials prevent water vapor loss and therefore reduce the level of bread becoming stale. in this study, seven types of nano-films with different...

The mechanical and water vapor permeability of starch/carrageenan cast films were investigated, the rheological properties of starch/carrageenan blends were also studied. The blends were prepared by different concentrations of starch and carrageenan. Three concentration of starch (0.75%, 1% and 1.25%) and two concentrations of carrageenan (0.5% and 0.75%) were used with adding 0.5% glycerol as ...

Cereal Chem. 72(1):1-6 Glass transition temperature (Tg) and mechanical and water vapor However, the Tg failed to change with solute composition and exhibited barrier properties of wheat gluten films containing glycerin, sucrose, low correlation with barrier and mechanical properties. Initial addition glycerin-sucrose, and glycerin-sorbitol were studied. Glycerin and sucrose of glycerin increas...
