Description
Eva Moll and Amparo Chiralt improve heat sealing of a biodegradable plastic by blending it with a second polymer, in a 2024 paper. The main polymer, PHBV, could replace conventional plastics, but it seals poorly with heat, which limits its use for bags. Blending may fix the seal yet change how well films block gases and vapors.
Three blend ratios were made by melt mixing and pressing. The two polymers stayed in apart phases, and which one formed the base phase flipped with ratio. More of the second polymer raised permeability and stretch but lowered stiffness. Its phase continuity gave the best seal strength. A half and half blend balanced seal and barrier best for food bags.
