This article focuses on increasing the shelf life of both pasteurized (Pa) and traditional (Tr) butters wrapped in Ag-Low Density Polyethylene (LDPE) film concentration 2.5%, 7.5%, 12.5%, 17.5% at refrigerated temperature up to one month. Silver nanoparticles were synthesized (20.63 nm) through chemical reduction followed by melt mixing method produce Ag-LDPE films. A mixed model-ANOVA Repeated...

Microplastic particles (MPs) are widely distributed pollutants in the environment. While a growing number of studies have shown that MPs toxic to plant and animal life, systemic efforts reduce their presence been scarce. Low-density polyethylene (LDPE) polystyrene (PS) one most common among all plastic-forming MPs. In this study, pure bacterial strains, Bacillus licheniformis Lysinibacillus &lt...

This work primarily investigated the pyrolysis of smalls scale fixed bed reactor using plastic wastes type LDPE during slow (non-isothermal) in a batch to assess effect different temperatures on product yield and heating value. The calorie bomb Parr Instrument was performed value pyro-oil at 250, 275, 300oC. obtained higher 300 oC while increased temperature will affect increase pyro-oil. highe...

Nowadays, nanoscale innovations in the forms of pathogen detection, active packaging, antimicrobial packaging and barrier formation are poised to elevate food packaging to new heights. Antimicrobial nanocomposite LDPE films containing ZnO nanoparticles at different concentrations (e.g. 1%, 3%, 5%  and 3%  nano-ZnO pulse 10% polyethylene grafted maleic anhydride (PE-g-MA), w/w pure LDPE), were p...

Title of Document: INVESTIGATING TWO-DIMENSIONAL BEHAVIOR OF ANTIOXIDANT ADDITIVES AND MIGRATION FROM FOOD CONTACT POLYMERS Wendy Marie Heiserman, Doctor of Philosophy, 2008 Directed By: Professor Robert A. Walker Department of Chemistry and Biochemistry Research described in this thesis examines the surface and bulk behavior of analytes in food contact polymers. Irganox 1076 (IN1076) and Irgan...

There is a paramount demand on the enhancement of plastic package properties to reduce food loss and waste. With this awareness, ternary composite films based low density polyethylene (LDPE) reinforced with silver- (Ag/FS), copper- (Cu/FS) copper hydroxynitrate-fumed silica (CuHS/FS) micron-sized dual-side fillers, were produced via melt-blending compression molding techniques. The exhibited an...

Abstract This research aims to assess the properties of Polymer Modified Bitumen (PMB) binder prepared with different types additives such as (Waste low density polyethylene (W-LDPE) and crumb rubbers (CR)and Styrene Butadiene (SBS)). Most these are sustainable materials since it is derived from old scrap materials. All above-mentioned (W-LDPE, CR SBS) were added percentages (2, 4, 6 percentage...

Multi-objective optimization of an industrial low-density polyethylene (LDPE) tubular reactor is carried out at design stage with the following objectives: maximization of monomer conversion and minimization of normalized side products (methyl, vinyl, and vinylidene groups), both at the reactor end, with end-point constraint on number-average molecular weight (Mn,f) in the product. An inequalit...

Olefin fibers, also called polyolefin fibers, are defined as manufactured fibers in which the fiber-forming substance is a synthetic polymer of at least 85 wt% ethylene, propylene, or other olefin units (1). Several olefin polymers are capable of forming fibers, but only polypropylene [9003-07-0] (PP) and, to a much lesser extent, polyethylene [9002-88-4] (PE) are of practical importance. Olefi...

This study aims to investigate the effect and possibility of using waste plastic as a sustainable cost-effective polymer modify bitumen binders. Different types have been used in this modification, including polyethylene terephthalate (PET), high-density (HDPE), low-density (LDPE). The modification targets physical characteristics, rheological properties, binders’ resistance ageing. Both long- ...
