Evaluation of Virgin and Recycled LDPE Plastic Bags Manufactured Using Film Blowing Machine Plastic is a versatile material that can be shaped and molded, making it a popular choice for a wide range of items. As a result, the demand for and manufacturing plastic bags is gradually increasing. Every year, it is estimated that trillions of plastic bags are used as carrying bags all over the world. Film blowing extrusion is the most common method for producing plastic films, particularly in the packaging industry. The raw material used is low density polyethylene (LDPE). Virgin and recycled LDPE plastic samples were collected from Wahdah Plastics Industries Sdn. Bhd. Plastic samples were bought from the internet are selected and purchased to undergo several testings and to make a comparison. Thus, in this study the mechanical properties of plastic bags are evaluated by using thickness measurement, density test, tensile test, tearing test and oxygen permeability test and make a comparison between the two companies from Wahdah Plastics Industry Sdn. Bhd. and the internet. The samples will undergo a few tests according to the American Standard Testing Method (ASTM) includes thickness measurement (ASTM D6988-13), tearing test (ASTM D689-03), tensile test (ASTM D882), oxygen permeability test (ASTM D1434-82) and density test. #PSM2 #JTKM #BNM #PSMFTKSem1_2021/2022
