“…The T 280 of PP/PBAT film was 3.4 ± 0.6%, indicating that the film possesses a high UV barrier property, which was mainly due to the carbonyl and benzene groups of the PBAT 20,21 . After the addition of Mel to the PP/PBAT composite films, the UV light transmittance was further reduced to 1.9 ± 0.1%, may be due to the presence of phenolic and indole groups in the Mel, which has a strong function of scattering or absorption of UV light 12 .…”

Polypropylene (PP) and poly (butylene adipate‐co‐terephthalate) (PBAT) blend films incorporated with melanin (Mel) were prepared using an extrusion casting method. Scanning electron microscopy results showed that Mel was evenly dispersed to form a well‐blended film. The PP/PBAT/Mel composite films prevented UV light transmittance, especially UV‐B rays. The addition of Mel influenced the surface color, water vapor transmission rate, oxygen transmission rate, and water contact angle of the composite films. After the addition of Mel, the tensile strength and elongation at break in the machine direction of the composite film increased by 30% and 27%, respectively. Packaging potatoes with PP/PBAT/Mel film and storing them under fluorescent light for 6 days effectively prevented the greening of potatoes caused by the production of chlorophyll. The PP/PBAT/Mel films have a high potential for the prevention of greening of potatoes during storage and distribution.

“…It is possible to observe that both PBAT and PLA have a hydrophobic character, and their behavior is close to the hydrophilic-hydrophobic transition limit, so, the degree of hydrophobicity is not so high. [21] With the addition of PLA in the PBAT matrix there was a decrease in contact angle, as long as when PLA content is increased, the WCA increases too. The results indicate that the hydrophilicity of the PBAT samples can be tuned by blending with PLA.…”

The growing search for biodegradable products contributes to the development of new materials. In this work, the effect of the Joncryl® ADR chain extender on poly(butylene adipate‐co‐terephthalate)/poly(lactic acid) blends was investigated. The mechanical, thermal, and morphological properties and the contact angle of the blends were also studied. The addition of the chain extender can either improve the adhesion between the phases or act as a stress concentrator, depending on the proportion of PLA present in the blend. However, in all samples, the elongation at break was increased. This behavior is also observed in the morphology of the blends, changing the shape of the PLA particles, from spherical to ellipsoid phase. However, in the proportion used (0.5 wt%), the chain extender was not enough to increase the adhesion between the phases of the blends, just the dispersion of the PLA particles. Besides, it is possible to observe that the higher the PLA content in the PBAT mixture, the lower wettability surface of the blends is reached.

“…The degradable polymers can be obtained from different technological routes, mostly from natural sources (cellulose and starch) or bacteria action on substrates, such as [poly (lactic acid) (PLA) and poly (3‐hydroxybutirate)]. However, other polymers like poly(butyrate terephthalate‐ co ‐adipate) and polycaprolactone can be synthesized from non‐renewable sources like petroleum. All these polymers, classified as polyesters, can be naturally degraded by the action of the abiotic process of hydrolysis in the environment and be applied in packaging, tissue engineering, and agriculture …”

The use of flexible films in agriculture has increased intensely in the last 15 years bringing benefits to producers. However, environmental impacts increased due to their incorrect post‐use disposal which leads the degradable films to emerge as an alternative. The production films of poly(butylene adipate‐co‐terephthalate) and poly(lactic acid) reinforced with calcium carbonate (CaCO3) was studied focusing on producing lower cost materials and flexible films. Four different films (reinforcement compositions) were prepared by melt extrusion with 10 and 20 wt % of CaCO3. Mechanical and thermal properties, crystallinity, water absorption, and soil degradation, were evaluated. The addition of reinforcement leads to improved compatibility between the polymers in the matrix, which usually presented phase segregation. The films showed better mechanical properties with the addition of CaCO3. Highly orientated amorphous structures were obtained leading to low water absorption and low degradation in the simulated soil. This low degradation, suggests that the obtained films would be of interest in flexible mulch films manufacturing, particularly for Muridori plantation system, where long‐term plantations are needed. © 2018 Wiley Periodicals, Inc.
