Screen Printed Moisture Sensor On Barrier Coated Sbs Board: The Characterizations Of The Hemicellulose-Based Biofilms And Their Applications For Smart Packaging, Ruoxi Ma

Dissertations

Fiber-based packaging materials have many advantages over their petroleum-based plastic competitors, such as sustainability, recyclability and stiffness/weight ratio. However, the poor barrier properties and sensitivity towards moisture are the main challenges for their extended use. Therefore, there has been a need to provide a biodegradable and biocompatible biopolymer packaging material with improved barrier properties for food and pharmaceutical packaging. Also, the moisture loss/gain problem causes a lot of waste every year. Therefore, there is a need of better tracking and sensing methods attached to the package in order to control the moisture level along the supply chain. To accomplish these …

The Reduction Of Glycerol Flow In A Porous Medium Through A Barrier Coating Application, Thomas Tran

Masters Theses

Coatings for paper are categorized into two groups: pigmented or functional. Functional coatings provide functionality in addition to the normal coating properties. Functional coatings can be used for friction control, release properties, abrasion resistance, and barrier properties. A coating that is designed to control barrier properties can be categorized into a sub-group of functional coatings called barrier coatings.

Barrier coatings can retard or eliminate the flow of fluids thru a coated substrate. The barrier can be effective in repelling or resisting the transmission rate of numerous fluids including moisture, oil, oxygen, grease, and glycerol. Barrier coatings have many useful applications …
