Improved PLA-Based Compounds Provide a Competitive and Carbon- Neutral Alternative to Polyethylene for Coated Paper Applications

چکیده
Extrusion coating is an established processing technology resulting in production of multilayer flexible structures. The operation involves melting of a thermoplastic to be applied onto a substrate such as paper (as shown in Figure 1). Polyethylene (PE) has been traditionally used for imparting properties such as water & grease resistance to the paper and in some cases barrier properties. This article discusses the problems and issues arising from a polyethylene coated paper when biodegraded under composting conditions and the benefits of selecting a fully compostable coating.

متن کاملSRL-coated PAMAM dendrimer nano-carrier for targeted gene delivery to the glioma cells and competitive inhibition by lactoferrin
Glioma, as a primary tumor of central nervous system, is the main cause of death in patients with brain cancer. Therefore, development of an efficient strategy for treatment of glioma is worthy. The aim of the current study was to develop a SRL peptide-coated dendrimer as a novel dual gene delivery system for targeting the LRP receptor, an up-regulated gene in both BBB and glioma cells. To perf...
