Description
Castro and six co-authors try to make a plant-based plastic film work better for food packaging in a 2025 paper. The plastic, PLA, is stiff and breaks down in compost, but on its own it is brittle.
The team mixed PLA with treated gelatin and a solvent blend that softens the mix. They compared two ways of adding the gelatin and checked structure, heat behavior, strength, and how fast the films break down. Adding the gelatin directly gave a smoother, more even film. The softener lowered the softening point and improved how the film could be shaped, though the films grew weaker than plain PLA. One blend stood out for stretch and ease of making. All films took up more water and broke down faster.
