Commercial Marine-Degradable Polymers for Flexible Packaging

Evaluation of three blackberry fruit types in Bio-degradable and nonbio-degradable packaging types

Plasma Surface Treatment of Commercial Polymers for use in Food Packaging

In this work plasma immersion (PI) was applied to Low Density Polyethylene (LDPE) and Polyethylene Terephtalate (PET) to improve their characteristics for food packaging. The effects of plasma composition were investigated by comparing treatments using N2 and SF6. Different treatment times were used at a total reactor pressure of 1.33 Pa composed by a steel vacuum chamber containing two interna...

flexible packaging structures for high pressure treatments

this paper reviews the possible effects determined on polymeric food packaging films by the simultaneous application of pressure (p) and temperature (t) in high pressure pasteurization and sterilization treatments of packaged foodstuffs. both theoretical modeling and experimental issues are discussed. in fact reversible and irreversible effects that could occur in single film as well as in mult...

Erosion kinetics of hydrolytically degradable polymers.

Degradable polymers are beginning to play an increasing role as materials for environmental and medical applications. Understanding factors that control erosion, such as bond cleavage and the dissolution and diffusion of degradation products, will be critical to the future development of these materials. Erosion kinetics, photomicroscopy, and infrared spectroscopy were used to understand the er...

New synthetic approaches to prepare degradable polymers

This thesis is concerned with the synthesis of acid labile co-polymers. Two polymer systems were examined (1) polyacetals and (2) poly(ortho esters). As for poly(ortho esters), there is a need for better synthetic methods to prepare these polymers more easily without the need of stringent anhydrous conditions, with more broad structural variation, and in a more cost effective manner. Pendent fu...
