“…The capacity of PLA to distribute itself through carrier fluids depends on its density. Commercial PLA particles typically have a specific gravity of 1.24 to 1.25 [48]. The transition temperature of glass (Tg) and the melting temperature (Tm) are frequently used as indicators of the thermophysical characteristics of PLA.…”

“…The transition temperature of glass (Tg) and the melting temperature (Tm) are frequently used as indicators of the thermophysical characteristics of PLA. The usual range for the glass temperature of the transition Tg of PLA is 323-353 K [48]. The melting temperature (Tm) of PLA is typically between 393 and 453 K; however, it occasionally reaches 483 K [44,45].…”

Approximately 50% of global plastic wastes are produced from plastic packaging, a substantial amount of which is disposed of within a few minutes of its use. Although many plastic types are designed for single use, they are not always disposable. It is now widely acknowledged that the production and disposal of plastics have led to a plethora of negative consequences, including the contamination of both groundwater and soil resources and the deterioration of human health. The undeniable impact of excessive plastic manufacturing and waste generation on the global plastic pollution crisis has been well documented. Therefore, degradable polymers are a crucial solution to the problem of the non-degradation of plastic wastes. The disadvantage of degradable polymers is their high cost, so blending them with natural polymers will reduce the cost of final products and maximize their degradation rate, making degradable polymers competitive with industrial polymers that are currently in use daily. In this work, we will delineate various degradable polymers, including polycaprolactone, starch, and cellulose. Furthermore, we will elucidate several aspects of polyvinyl alcohol (PVA) and its blends with natural polymers to show the effects of adding natural polymers on PVA properties. This paper will study cost-effective and ecologically acceptable polymers by combining inexpensive natural polymers with readily accessible biodegradable polymers such as polyvinyl alcohol (PVA).
