Polyethylene terephthalate (PET), due to its excellent physical and chemical properties, has become a widely used packaging material for liquids across many consumer market segments. However, one of the most common problems met in bottle manufacturing is pile-up bottles during conveying, static electrification caused by localized friction. To minimize such phenomena, thin lubricant layer applie...

The degradation of two poly(ethylene terephtalate) (PET) samples from urban and marine wastes (PET-u PET-m, respectively) has been studied by comparing their properties with those virgin PET (PET-v) post-condensed for bottle fabrication (PET-ssp). FTIR spectroscopy, DSC analysis, WCA MFI results have confirmed that all residues were degraded. Therefore, the chemical recycling evaluated in order...

In order to corroborate the efficiency of PET bottle inspection equipment coupled with mass spectrometry detection, a method for determination of BTEX presented in the interior of returnable PET bottles was developed and validated. It was verified that the method was able to detect BTEX compounds in the range 0.1-10mL of gasoline.

Simulation of the stretch blow molding (SBM) process necessitates to develop a model able reproduce material behavior at high strain rate, large deformation with temperature gradient. On other hand, both need understand polyethylene terephthalate (PET) characteristics and final bottle performance requirements continue get higher. That regular update identification model. Bottle producers are in...

There has been a considerable imbalance between the availability of conventional building materials and their demand in recent past. On other hand, plastic waste is abundantly available disposal Polyethylene Terephthalate Plastics (PET) big challenge, as repeated recycling PET bottles poses potential danger being transformed only small proportion are recycled. In this work an attempt made to ac...

A CAD paradigm is presented to produce blow moulds for Poly Ethylene Terephthalate (PET) bottles decorated with ornamental patterns. This work integrates design and manufacturing of decorated blow moulds which, in turn, are utilized to blow PET bottles. The parametric geometric modeling techniques are employed to customize a CAD system, tailoring to suit the requirements of the bottle making in...
