Abstract We compared the performance of bio-based and biodegradable polymers for packaging applications. Cost-effective inorganic fillers (talc, kaolin calcium carbonate) were first melt-compounded with polylactic acid (PLA), poly(butylene adipate-co-terephthalate) (PBAT) poly(hydroxy butyrate-co-valerate) (PHBV). Following this, injection- compression-molded specimens produced to test effect f...

Abstract The ratio of poly(lactic acid) (PLA), poly(butylene adipate- co -terephthalate) (PBAT), and calcium carbonate (CaCO 3 ) fillers in PLA/PBAT/CaCO composites was set at 90/10/5, 70/30/5, 30/70/5. effect nano- micro-CaCO on the melting crystallization performance investigated by differential scanning calorimetry. PLA related to PBAT ratio, cooling rate, CaCO particle size composites. Nano...

An extracellular lipase from Amycolatopsis mediteranei (AML) with potential applications in process biotechnology was recently cloned and examined this laboratory. In the present study, 3D structure of AML elucidated by comparative modelling. lacked 'lid' observed most true lipases shared similarities plastic degrading enzymes. Modelling substrate specificity studies showed that a cutinase rela...

Polyesters, such as poly (butylene terephthalate) (PBT), owe a rather low melt strength, which is considered not beneficial for foaming. To overcome this issue, typical attempt the incorporation of chemical modifications—so-called chain extenders (CE)—in reactive extrusion process. In study, reaction kinetic variables are investigated depending on material and process parameters. For purpose, d...

Abstract A blend of poly(butylene adipate terephthalate) (PBAT) and polylactide (PLA) is a combination biodegradable materials. This study aims to prepare compatibilized PBAT/PLA in cost-effective timesaving way process the material into blown films by fine-tuning processing parameters. First, catalyst masterbatch prepared transesterification PBAT PLA presence tetrabutyl titanate (TBT) as catal...

The main aim of the present study was to determine the behavior of the specimens from Ecovio, in the form of dumbbell-shaped samples and films, during degradation in selected cosmetic ingredients such as water and paraffin. The (bio)degradation test of the prototype cosmetic package (sachet) made from a PBAT (poly[(1,4-butylene adipate)–co–(1,4-butylene terephthalate)]) and PLA (polylactide) bl...
