ŠIMKO P., SKLÁRŠOVÁ B., ŠIMON P., BELAJOVÁ E. (2006): Effect of plastic packages on benzo[a]pyrene concentration in sunflower oil. Czech J. Food Sci., 24: 143–148. Commercially available sunflower oil and the same oil distilled additionally in a molecular evaporator (to remove naturally occurring compounds) was spiked with benzo[a]pyrene (BaP) at the levels of 37.1 and 38.6 μg/kg, respectively....

This study aims to characterise fatigue cracking of two types waste-derived (bio-oil and LDPE) bitumen. Modified Paris’ law Griffith criterion were proposed investigate crack propagation initiation the Results show that bio-oil delays LDPE accelerates initiation, bitumen itself dominates unaged The did not take effects in altering bitumen’s performance after pressure ageing vessel (PAV) ageing....

Abstract Graphene Oxide (GO) was added to Low-Density Polyethylene (LDPE) test the mechanical properties of compound. Compared other types polyethylene, LDPE provides a good balance and processability, which leads its being chosen as research’s matrix material. This experiment aims prepare LDPE/GO through melt mixing technique analyse tensile strength/tensile elongation composite based on GO co...

Aiming at reducing the environmental impact of low density polyethylene (LDPE) when employed as mulching film, this study was focused on partial substitution material with proteins extracted from Hermetia illucens, also known black soldier fly (BSF). Insects were reared chicken manure and food leftovers in a circular economy perspective. To evaluate effects processing conditions amount BSF prop...

The present investigation aimed to evaluating the combined effect of post harvest treatments, packaging and storage conditions on the changes in sugars and lycopene content of tomato. Tomato fruits with stalk and without stalk were harvested at breaker stage and subjected for shelf life studies. The fruits with best harvesting method (fruits with stalk) were treated with chlorine by first dippi...

In this paper the relationship between molecular structure and behavior of the LDPE melt is discussed from a scaling perspective on the bases of results from GPC-MALLS analysis. Long chain branches introduce a characteristic length scale that marks a transition in rheology behavior of the melt with decreasing length scale of deformation i.e. with increasing process rate or decreasing temperatur...

Laminated aluminum foils are increasingly being used to protect drug products packaged in semipermeable containers (e.g., low-density polyethylene (LDPE)) from degradation and/or evaporation. The direct contact of such materials with primary packaging containers may potentially lead to adulteration of the drug product by extractable or leachable compounds present in the closure system. In this ...

The aim of this study was to develop and optimize a reproducible flexible sensor adapted to thin low-density polyethylene (LDPE) films and/or structures to enable their deformation measurements. As these deformations are suspected to be weak (less than 10%), the developed sensor needs to be particularly sensitive. Moreover, it is of prime importance that sensor integration and usability do not ...

Waste plastic pollution is a serious issue. In order to adhere the concept of green development and rationally dispose polyethylene waste products, (PE)-modified asphalt was prepared using recycled (RPE) low-density (LDPE) as raw materials. The chemical structures RPE- LDPE-modified were studied Fourier transform infrared spectrometer (FTIR), dispersion RPE fluorescence microscope (FM). Subsequ...

Environmental pollution by microplastics (MPs) has become a global problem, but little is known about MPs in soils. This because MP extraction methods from soils have not yet been standardized. In this study, we tried to establish simple and economical method extract soil using the buoyancy of canola oil density separation process sodium chloride (NaCl). addition, incineration was adapted evalu...
