Blends of thermoplastic starch and some thermoplastic polymers

, 1998
Thermoplastic starch (TPS) was blended in a twin screw mixer with 5 and 10 mass % of poly(ethylene-co-acrylic acid) (EAA), poly(ethylene-co-vinyl acetate) (EVA) or cellulose acetate (CA) in order to improve the TPS properties. The influence of such low amounts of thermoplastic polymer (TPP) on the processability, mechanical properties and water ...

Multilayer Cellulose Acetate–Viscose Films for Bio‐Based, Bio‐Degradable Packaging Applications

Packaging Technology and Science, Volume 39, Issue 6, Page 685-695, June 2026.
Cellulose acetate (CA) and cellulose foils stick together comprehensively after mild cellulose sodium hydroxide treatment and heated compression. For combined foils, water barrier properties correlate with CA thickness. Oxygen permeation suffers due to the sodium hydroxide pre‐treatment induced foil changes. The composite represents a biodegradable and

Retrogradation and Antiplasticization of Thermoplastic Starch

, 2012
Petrochemical-based plastics are widely used in modern society due to their high effective mechanical and barrier properties (Farris et al., 2009; Siracusa et al., 2008). However, petrochemical-based plastics have become an environmental concern as they are not biodegradable or recyclable.
