Evaluation of some eco‐friendly plasticizers for PLA films processing
Five Poly (lactic acid) (PLA) film samples were analyzed to study the gas barrier behavior, thermal stability and mechanical performance for food packaging application, and thermal properties such as Tg and χc, and mechanical properties were remarkably improved with surface PLA modification. 15 PDF
Evaluation of some eco‐friendly plasticizers for PLA films processing
Different types of nontoxic biocompatible plasticizers/lubricants, both obtained in the laboratory, as well as commercial ones, were employed to modulate physical and mechanical properties of PLA. Melt compounding by means of a Brabender mixer led to obtaining of homogeneous materials.
Evaluation of some eco‐friendly plasticizers for PLA films processing
ABSTRACT This study was conducted as a first step in order to obtain green materials for food packaging by using an eco-friendly bioplastic, polylactic acid (PLA), and nontoxic plasticizers.
Evaluation of some eco-friendly plasticizers for PLA films processing
The presence of plasticizers in the PLA-based films is a usual method that is often used to enhance the flexibility, extensibility, and processability of PLA by increasing the mobility of...
Long- and short-term stability of plasticized poly(lactic acid
To evaluate the long-term thermal, mechanical, and morphological properties, PLA and PLA with 15 wt% plasticizer had been stored in double-layer polyethylene bags at a temperature of 25 ± 2 °C and relative humidity of 40–65% for 4 months and 1 and 2 years after compounding.
- Which bio-based plasticizers are used in PLA film compositions?
- Singh et al. used two different bio-based plasticizers, TEC and glycerol triacetate (GTA), and two naturally obtained fillers, halloysite nanotube (HNT) and chitosan in PLA film compositions intended for packaging applications .
- What is an example of a plasticizer?
- An example is Ecovio®, a commercially available compound that relies on a blend of PLA and PBAT, specifically designed for packaging applications . The incorporation of plasticizers into PLA is another common practice to improve its inherent limitations .
- What are the potential antimicrobial plasticizers based on PLA and ecovio®?
- SOFT-NSAFE and CITREM-LR10 compounds were then employed as potential antioxidant and antimicrobial plasticizers in films based on PLA and Ecovio®. These plasticized films (with a thickness of about 200 μm) were prepared by melt extrusion followed by compression moulding.
- Can citric acid be used as plasticizer in PLA and ecovio® biopolymers?
- Herein, a derivative of citric acid (CITREM-LR10), usually used as food additive, was evaluated for the first time as plasticizer in PLA and Ecovio® biopolymers. Films containing 10 % (w /w) of CITREM-LR10 were prepared and compared with films plasticized with another biobased compound, SOFT-NSAFE, derived from acetic acid.
- Can Liquidambar orientalis be used as a plasticizer?
- In this study, it has been shown for the first time that the Liquidambar Orientalis (LO) oil as a nontoxic, environmentally friendly, and green additive can be successfully used as a natural, renewable, and sustainable plasticizer to produce flexible PLA parts and improve its thermal and physical properties and application potential.
- Do plasticizers affect the double melting behaviour of PLA?
- As can be seen, the double melting behaviour of PLA was also affected by the incorporation of the tested plasticizers as indicative of the changes that they provoke in the size and perfection of the crystals. Subsequently, the mechanical properties of the plasticized and unplasticized films were evaluated by tensile testing.
