Low Density Polyethylene (LDPE) is produced by free radical polymerization. Industrially, LDPE polymerization process is usually carried out in a continuous mode (tubular or autoclave reactors) at high pressures (1300-3400 atm) and temperatures (50-340 0 C). LDPE exhibits a number of desirable properties, including high tensile strength, flexibility, high impact resistance, low crystallinity, l...

Individual sealing and tray wrap of orange (Citrus sinensis (L.) Osbeck cv. ‘Valencia’) with heat-shrinkable films of low-density polyethylene (LDPE), high-density polyethylene (HDPE), oriented polypropylene (OPP) and polyvinyl chloride (PVC) were held for a period up to 4 months at 5°C and 85-90% RH. Both methods of film-packaging showed little change in the water relations characteristics, wh...

The effect of the addition of I % by weight of titanium dioxide fine particles to low density polyethylene (LDPE) on the short-term d.c. breakdown strength of the LDPE was investigated using direct and reverse polarity voltages. The samples used, were cylinders of both plain and doped materials, with hemespherically tipped cylinderical electrodes completely embedded in the material, with a mini...

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...

The scope of this study is to enhance the industry understanding of the sustainable utilization of quarry dust, and to identify any gaps in current knowledge. The term sustainable utilization implies the use of quarry dust to their full potential to meet the needs of the present, while at the same time conserving natural resources and finding ways to minimize the environmental impacts associate...

Two sample sets of low density polyethylene (LDPE) were investigated and differentiated via comprehensive analysis their microstructures with specific emphasis on branching.

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 effects of poly(lactic acid) (PLA)-based film with inorganic antimicrobial nano-TiO₂ and nano-Ag on the physicochemical and microbial quality of Tremella aurantialba stored at 4 ± 1 °C for 16 days was investigated. Rosemary essential oil (REO, 9 wt %) was added into PLA film as plasticizer. Low-density polyethylene (LDPE) and PLA film was used as the controls. The experiment measured physic...
