Spray process to styrene grafting onto polyethylene film surface for paintability enhancement
A direct and fast post-processing method to modify polyethylene (PE) film surface is proposed in order to improve its paintability performance without changing its bulk properties. This goal is achieved by grafting styrene ...
Breathable polyethylene/sepiolite nanocomposite ﬁlms
(Society of Plastics Engineers, 2013-11)
Polyethylene/sepiolite nanocomposite films provide a new material with high elongation at break and transparency, increased Young's modulus and strength, and higher gas permeability.
Development of an antifungal film by polyethylene surface modification with natamycin
(Elsevier Ltd, 2018-12)
An antifungal low-cost film for cheese packaging was developed using a tailor-made coating process by direct natamycin (Nat) spraying onto heat softened polyethylene film surface. Two spraying systems Nat/ethanol solution ...
Essential work of fracture of photo-oxidized LDPE/EVA films
The Essential Work of Fracture approach (EWF) was used to determine how UV-C irradiation alters the fracture behaviour of LDPE/EVA films. Complementary characterization was performed by FTIR, DSC, TOM, and uniaxial tensile ...
Physical, structural and antioxidant properties of brewer's spent grain protein films
(John Wiley & Sons Ltd, 2020-06)
The development of brewer's spent grain protein (BSG‐PC) films with potential active packaging properties was investigated. Films were prepared by casting protein dispersions at different pH values (2, 8, 11), plasticizers ...
Controlled release of micronutrients from surface-modified polymer films for agricultural applications
Active polyethylene/carbon black films with the capability of controlled release of micronutrients were developed in this work. A simple technique allowed modifying film surface through the incorporation of different mineral ...
Fatty acid extraction from sewage sludge using a porous polyethylene sorbent obtained from agricultural covers
(Pergamon-Elsevier Science Ltd, 2018-08)
Fatty acids from a sewage sludge of a wastewater treatment plant were extracted using a porous polyethylene (pPE) material prepared using agricultural plastic films. The pPE fatty acid extraction profile and yield from the ...
Exhausted grape marc and organic residues composting with polyethylene cover: process and quality evaluation as plant substrate
In Argentina, wine production is one of the most important economic activities, producing a large quantities of organic wastes. Composting is a viable alternative to treat these residues, with the possibility to obtain ...
Lignin-Based Polyethylene Films with Enhanced Thermal, Opacity and Biodegradability Properties for Agricultural Mulch Applications
(Springer/Plenum Publishers, 2021-02)
Lignins are promising alternative raw materials for biocomposites due to their renewability, low cost and abundance. In this work, the use of (softwood and hardwood) Kraft lignins in the development of LLDPE/lignin films ...
An insecticide formulation of terpene ketones against Sitophilus zeamais and its incorporation into low density polyethylene films
The use of active natural compounds derived from plants appears as an interesting alternative for pest control in stored products. In this study, the fumigant toxicity of several terpene ketones against maize weevil ...
