Sustainable, High Barrier Smart Packaging Films for Shelf-Life Extension of Edible Oils.

Smart packaging is revolutionizing the food industry by extending shelf life and enhancing quality, thus ensuring food safety and sustainability. This study presents innovative multilayer flexible packaging films to tackle the environmental challenges of single-use plastics and nonrecyclable metalized multilayer films. The fabricated films comprise three layers made up of poly(lactic acid) (PLA), poly(vinyl alcohol)/natural rubber latex, and PLA/Sepiolite clay from inner to outer, respectively, where the active middle layer provides oxygen-scavenging activity.

Unravelling polysilazanes: Synthesis, structure-property insights and versatile coating applications.

Therefore, herein, we present the fabrication and characterization of water-based CDs and CNCs from (black lentil: BL).

Solvent-Selective Fluorescence Sensing of Mg and Al Ions by Pincer-Type NNO Schiff Base Ligand: An Experimental and DFT Optimized Approach.

A newly developed dual-functional fluorescence sensing probe (phenylhydrazinyl pyridine) Schiff base (SB) has been designed with good selectivity for distinguishing Mg and Al metal ions in different solvent solutions. SB exhibits quick and visual turn-on fluorescence enhancement in response to Mg and Al detection. The addition of Mg in ACN-HEPES buffer (1 : 1, v/v, pH 7.

Investigating the Reactive Reinforcement Ability of Maleic Anhydride-Modified Cellulose Nanocrystals via In-Situ Emulsion Polymerization.

CNC-based nanocomposites have gained substantial interest because of their enhanced thermomechanical properties for high-end engineering applications. The chemical modification of CNCs expands their applicability, making them suitable for use in hydrophobic polymer matrices. The current study investigates the reactive reinforcing ability of maleic anhydride-modified cellulose nanocrystals during the in situ polymerization of a vinyl monomer, i.

UV-blocking biodegradable film based on flaxseed mucilage/pectin impregnated with titanium dioxide and calcium chloride for food packaging applications.

A UV blocking and potentially biodegradable composite films are fabricated from flax seed mucilage and pectin with different concentrations of titanium dioxide (TiO) and crosslinked with calcium chloride (CaCl). This study aimed to evaluate the physical, surface, and optical properties including color, potential biodegradability, and absorption kinetics of the developed film. From the observations made, addition of 5 wt% TiO enhanced UV barrier property with a total color change (ΔE) of 23.

Bio-based materials for barrier coatings on paper packaging.

Research into alternative packaging materials is becoming more and more popular as a result of growing eco-friendly concerns regarding the usage of some petroleum-based polymeric packaging materials and coatings, as well as growing buyer demands for products with nutritious quality and extended shelf lives. Barrier coatings made of naturally renewable biopolymers can be applied to paper packing materials. These biopolymer coatings have the potential to replace the current synthetic paper and paperboard coatings, are strong oxygen and oil barriers, and may prevent the unintended moisture transfer in food goods.

Package design as a branding tool in the cosmetic industry: consumers' perception vs. reality.

The product packaging plays a crucial role in attracting consumers, persuading them to buy the product, and serving as a vehicle for brand communication. Around 73% of purchasing decisions are made at the point of sale. An enhanced appeal and attractiveness of the product make the selection process easier for consumers.

Guar gum/carboxymethyl cellulose based antioxidant film incorporated with halloysite nanotubes and litchi shell waste extract for active packaging.

The incorporation of bioactive extract from the food waste into biopolymers is a promising green approach to fabricate active films with antioxidant activity for food packaging. The present study developed bioactive antioxidant films based on guar gum/carboxymethyl cellulose incorporated with halloysite-nanotubes (HNT) and litchi shell extract (LSE). The effects of combining HNT and LSE on the physical, mechanical, and antioxidant properties of the films were analyzed.

Advanced packaging for distribution and storage of COVID-19 vaccines: a review.

The outbreak of the coronavirus disease 2019 global pandemic (COVID-19) has affected billions of lives, posing critical challenges to the healthcare system, vaccine manufacturers, packaging scientists, and daily public activity.
