Linear low-density polyethylene (LLDPE) based composites were prepared by melt compounding with 1, 2, 3 and 4 vol% of various kinds of amorphous silicon dioxide (SiO2) microand nanoparticles. Dynamic rheological tests in parallel plate configuration were conducted in order to detect the role of the filler morphology on the rheological behaviour of the resulting microand nanocomposites. A strong...

Contamination of food products by spoilage and pathogenic microorganisms during post process handling is one of the major causes for food spoilage and food borne illnesses. The present green sustainable approach describes the covalent immobilization of papain to LDPE (low density polyethylene), HDPE (high density polyethylene), LLDPE (linear low density polyethylene) and PCL (polycaprolactam) w...

Background/Objectives: The primary goal of using active packaging is to extend the shelf life products inside package. This research aimed study properties LLDPE with Ag-zeolite nanoparticles product shelf-life. Methods/Statistical analysis: In this research, films combined at 0.5 and 1 % wt. were produced by a twinscrew extruder blown film extruder. inspected included physical properties, mech...

A combination of room cooling and the use thermal insulation materials to maintain okra quality under simulated storage transportation was evaluated. Okra pods were packed in plastic baskets either cooled at 18 °C or not a for 2 h. After no cooling, covered with three different materials: (1) perforated linear low-density polyethylene (P-LLDPE), (2) two layers heat-reflective sheet thin nonwove...

The heat-seal strength and failure modes of laminated films with Linear Low Density Polyethylene (LLDPE) and Low Density Polyethylene (LDPE) as the sealant materials were investigated. Heat-seal strength increases with platen temperature for all samples. The maximum achievable heat-seal strength for laminated film using LDPE and LLDPE as sealant material is 0.598 N/mm and 4.02 N/mm, respectivel...

The degradation of different polyethylenes, LDPE, LLDPE, and HDPE, with and without antioxidants and at different oxygen concentrations in the polymer granulates have been studied in extrusion coating processing. The degradation was followed by On Line Rheometry, Size Exclusion Chromatography, Surface Oxidation Index measurements, and GC-MS Chromatography. The degradations starts in the extrude...

Two grades of metallocene-catalysed LLDPE and one grade of low-density polyethylene (LDPE) have been silane grafted and crosslinked by contact with water and their performance has been compared and evaluated. The effects of vinytrimethoxysilane (VTMOS) levels on the degree of crosslinking for each grade were also studied. It was found that increasing level of silane increases the degree of cros...

Abstract Diffuse coplanar surface barrier discharge (DCSBD) was used to activate the opposite side of plasma‐exposed linear low‐density polyethylene/polyamide (LLDPE/PA) tubular film multilayer casing. We determined that conductive metal rubber roller in DCSBD system allowed formation microfilaments perpendicular surface, resulting improved wettability and adhesion inner LLDPE film. These findi...

Composites of strontium titanate (SrTiO3) at loadings up to 50 vol.% with polar poly(butylene terephthalate) (PBT) and non-polar linear low density polyethylene (LLDPE) were prepared investigate their dielectric responses in the wireless frequency range. The SrTiO3 particles uniformly dispersed polymers loadings, but more bead-like agglomerated higher loadings. has a strong nucleating effect on...

Abstract Plastisphere is a term for any microbial community that grow and develop on the surface of plastic. There was still lot plastics readily disposed in landfills, which would makes it feasible to discover bacteria could decompose plastic be used bioremediation. The present study aims determine number density (colonies) obtainining (bacteria, fungi) isolates from four different types namel...
