Optically transparent membrane based on bacterial cellulose/ polycaprolactone
(2013-05-10)
Optically transparent membranes from bacterial cellulose (BC)/polycaprolactone (PCL) have been prepared by impregnation of PCL acetone solution into dried BC membranes. UV-Vis measurements showed an increase on transparency ...
Identification of fatty foods with contamination possibilities by plasticizers when stored in PVC film packaging
(Sociedade Brasileira de Ciência e Tecnologia de Alimentos, 2011)
Poly-(vinyl chloride) (PVC) requires the addition of plasticizers - additives that give flexibility and malleability for its processing into flexible film. The most used ones are: di-(2-ethylhexyl) adipate (DEHA) and ...
Economic implications of the ban on single-use plastics in the Caribbean: A case study of Trinidad and Tobago
(ECLAC, 2020-11-04)
Over the past 50 years, the global annual production of plastics has increased dramatically, from 15 million tons in 1964 to roughly 311 million tons by 2014. This spectacular growth has occurred due to its unrivalled ...
Thermal and mechanical characterization of plasticized poly (L-lactide-co-D,L-lactide) films for food packaging
(Springer, 2006-12)
In this work amorphous poly(L-lactide-co-D,L-lactide) (PLLA/PDLLA) was blended with four different commercial adipates to obtain films with enhanced mechanical and thermal properties. Efficiency of plasticizers was evaluated ...
