The biodegradable polymer PBAT is hitting the big time
In South Korea, LG Chem is building a 50,000 metric ton (t) per year PBAT plant set to open in 2024 as part of a $2.2 billion sustainability-focused investment program in Seosan. SK Geo Centric, formerly known as SK Global Chemical, and Kolon Industries are partnering on a 50,000 t PBAT plant in Seoul.
Natural-based plasticizers and biopolymer films: A review
Plasticizers, for biopolymer-based films, can be divided into water soluble and water insoluble [25]. The type and the amount of plasticizer strongly affect the film formation from polymeric aqueous dispersions [26]. Hydrophilic plasticizers dissolve in the aqueous medium when they are added to polymer dispersions and if added in high
Plasticizers for Biopolymer Films - Glass Transition and
Plasticizers are important additives that diminish the brittleness and impart adequate flexibility and processability to polymers. Plasticizers are low molecular weight agents added to polymeric materials such as plastics, biopolymer based films, paints, or adhesives, to produce or promote plasticity, flexibility, processability and to reduce
Title: A Review on Plasticizers and Eco-Friendly
Citrate plasticizers have good miscibility, biodegradable, resistant to leaching and water and have legal use as additives. The demand for bioplasticizers is reported to increase from 887 kiltonnes in 2016 to 1900 kilotonnes in 2025 with a corresponding revenue of $1124 Million dollars 2016 to $2683.7 Million dollars by 2025.

Without a plasticizer, biopolymer materials are usually brittle due to a crosslinked network of densely hydrogen-bonded chains. Plasticizers help to break the original hy-
- Why are plasticizers used in biopolymers?
- Plasticizers are molecules of low volatility which are added to biopolymer materials to allow the modification of the functional properties of films by increasing their extensibility, dispensability, flexibility, elasticity, rigidity and mechanical properties (Hanani et al., 2014a, Hanani et al., 2014b).
- Are polyols a good plasticizer?
- Polyols are good plasticizers for protein-based materials such as gelatin films. Beneficial compounds of plasticized gelatin film can be used as biodegradable food packaging. Glycerol and sorbitol were found to show considerable plasticizing effect on gelatin-based film.
- Do plasticizers affect the functional properties of biodegradable gelatin-based films?
- Thus, addition of plasticizers into the film materials improves the functional properties of films by increasing their extensibility, dispensability, flexibility, elasticity, and rigidity. This study aims to review the current findings on how plasticizers impact the functional properties of biodegradable gelatin-based films.
- Which polymer has the optimum plasticizer effectivity?
- Generally, with a given polymer such as polyvinyl chloride, for each plasticizer such as the sebacates, adipates, or phthalates, there is a molecular weights range in which the plasticizer effectivity is optimum (Chen & Zhao, 2012).
- Are biopolymers a good substitute for conventional plasticizers?
- The use of natural and/or biodegradable plasticizers, with low toxicity and good compatibility with several plastics, resins, rubber and elastomers in substitution of conventional plasticizers, such as phthalates and other synthetic conventional plasticizers attracted the market along with the increasing worldwide trend towards use of biopolymers.
- How do plasticizers affect a polymer matrix?
- Plasticizers incorporation in the films may affect the continuity of the polymer matrix, leading to physical changes, where the films become more flexible and stretchable.
