Effect of Cold Plasma Treatment on the Packaging Properties of Biopolymer-Based Films: A Review

open access: yesApplied Sciences, 2022
Biopolymers, like polysaccharides and proteins, are sustainable and green materials with excellent film-forming potential. Bio-based films have gained a lot of attention and are believed to be an alternative to plastics in next-generation food packaging.

How to combine a hydrophobic matrix and a hydrophilic filler without adding a compatibilizer – Co-grinding enhances use properties of renewable PLA-starch composites [PDF]

open access: yes, 2012
In order to avoid the use of compatibilizers or plasticizers, co-grinding was performed to produce PLA – starch composite materials. Fragmentation and agglomeration phenomena were analysed to propose a production mechanism.

Development auxiliaries for dyeing polyester with disperse dyes at low temperatures [PDF]

open access: yes, 2017
High-molecular weight organic compounds known as carriers are widely used to expedite polyester dyeing at atmospheric pressure at 100 °C. However, carriers are usually poorly biodegradable and can partially plasticize fibres. Also, dyeing at temperatures

Enhancing Corrosion Resistance and Mechanical Strength of 3D‐Printed Iron Polylactic Acid for Marine Applications via Laser Surface Texturing

open access: yesAdvanced Engineering Materials, EarlyView.
Laser surface texturing significantly improves the corrosion resistance and mechanical strength of 3D‐printed iron polylactic acid (Ir‐PLA) for marine applications. Optimal laser parameters reduce corrosion by 80% and enhance tensile strength by 25% and ductility by 15%.

Preparation of Sustainable Alginate/Chitosan Blend Films by Thermo-Compression for Diverse Applications

open access: yesGels
In this work, sodium alginate/chitosan (SA/CS) blend films were prepared by thermo-compression for the first time. Glycerol and lactic acid were used as de-structuring agents for SA and CS, respectively.

SYNTHESIS AND CHARACTERIZATION OF NANO CHITOSAN-AVOCADO SEED STARCH AS EDIBLE FILMS

open access: yesJurnal Kimia Riset, 2023
The use of plastic as food packaging tends to cause problems because it is difficult to decompose; therefore, it can pollute the environment. The development of biodegradable plastics is an alternative to this problem. Chitosan, a bioplastic, can be used
