Production, Characterization and Chemical migration studies of PP/PP-Regrind Scrap Ratio for Concentrated

Abstract

In this research, the ratio of PP and PP-REGRAD was determined to be used for research and testing the quality preservation of concentrated tamarind juice products in PP packaging. Recycled polypropylene [PP: PP-REGRAD], including 100:0, 90:10, 80:20, 70:30, and 60:40 respectively by injection molding process. Different mixing ratios cause changes in the internal structure and properties. of plastic bottles Analyzed by Fourier transform infrared spectroscopy (FTIR), X-ray diffraction analysis (XRD), tensile strength (TS), Dynamic Mechanical Thermal Analyzer (DMTA), Differential Scanning Calorimetry (DSC), Thermogravimetric Analysis (TGA), Oxygen Transmission Rate (OTR), High-Performance Liquid Chromatography (HPLC), Inductively coupled plasma-mass spectrometry (ICP-MS), % Total soluble solid, and PH Meter found that Results of tests on mechanical properties Resource capacity and tensile strength tests were performed using polyethylene. (PP-Regrind) is not allowed to work in the tensile plant of polyethylene (PP). Therefore, using plastic bottles with suitable ratios was tested to maintain the quality of concentrated tamarind juice due to physical and chemical evaluation. It is a promising alternative to controlling the migration of chemicals from plastic bottles to food products. Therefore, plastic bottles derived from polypropylene and recycled polypropylene has the ability to maintain the quality of concentrated tamarind juice for a specified period of time and can be used in the food industry in the future.
