The biodegradation of spent saline bottles, a low density polyethylene product (LDPE) by two selected Arthrobacter sp. under in vitro conditions is reported. Chemical and UV pretreatment play a vital role in enhancing the rate of biodegradation. Treated LDPE film exhibits a higher weight loss and density when compared to untreated films. Arthrobacter oxydans and Arthrobacter globiformis grew be...

Methodology Active packaging material was low density polyethylene (LDPE) film incorporated with Tinuvin 326(UV absorber) and iron powder in different concentrations (0-0.5% and 0-15% w/w, respectively). Eleven treatments were performed according to the central composite design (CCD) in order to evaluate changes in mechanical, physical and barrier properties of films. Moreover, the influence of...

Lignin, a byproduct of paper and pulp industries, is a sustainable, inexpensive biomaterial with potential as composite filler. Past research on polyolefin/lignin composites made by melt processing has led to modest increases in Young’s modulus and drastic reductions in tensile strength and elongation at break relative to neat polymer. Here, green hybrids of low density polyethylene (LDPE) and ...

Degradation of Petroleum-plastics like Low Density Polyethylene (LDPE) is a budding challenge due to increasing white pollution. The present investigation has focused the aspect through microbial assisted biodegradation. Various indigenous microorganisms were isolated from collected municipal landfill soil. Growth medium enriched with 0.2 g of LDPE powder was used to screen the soil bacteria wi...

This article reports a study of the thermo-oxidation and biodegradation in the soil of low-density polyethylene/starch films (LDPE/starch) by infrared spectroscopy: Films of LDPE/Starch blends of different composition (starch content range from 0 to 15% w/w),were prepared and exposed to thermo-oxidation at different temperatures at 80, 90 and 100°C,and buried in the soil of public dump duri...

This report describes the production of ERM-EC680m, a low-density polyethylene (LDPE) material certified for the mass fraction of elements. The material was produced following ISO Guide 34:2009. An LDPE material containing certain elements was prepared from commercially sourced low-density polyethylene and organic and inorganic pigments. The material was extruded, mixed and filled into bottles....

The low-density polyethylene/aluminum (LDPE/Al) joint in Tetra Pak provides stability and strength to food packaging, ensures protection against outside moisture, maintains the nutritional values flavors of without need for additives products. However, a poor adhesion LDPE Al, due its non-polar surface, is limiting factor extra polymeric interlayers or surface treatment required. Plasma-assiste...
