Abstract

The FTIR test results show mylar plastic sample is a polybutylene terephthalate polymer. Laraska 1, laraska 2 and laraska 3 plastic samples are polyvinyl alcohol polymers. Mika Asahi and Astralon Restorasi 1 plastic samples are polyvinyl chloride polymers. The plastic samples of Astralon Restorasi 2, Astralon Restorasi 3 and Plastik Sablon are poly (cyclohexadimethylene) terephthalate polymer. 3M double-sided tape samples are Cellulose Acetate-Based Backing Tapes and Acrylic Based Adhesive Tapes, kenko, joyco and subaru double-sided tape samples are Polypropylene-Based Backing Tapes and Rubber (Synthetic) Based Adhesive Tapes. There was an increase in MD direction tear strength values after aging in Mylar (50.67%), Plastik Sablon (11.58%), Mika Asahi (21.12%), Astralon Restorasi 1 (24.02), and Astralon Restorasi 3 (34.87%) samples and a decrease in Astralon Restoration 2 (3.27%) samples. There was an increase in tear strength values in the CD direction for Mylar (20.67%), Mika Asahi (15.14%), Astralon Restorasi 1 (30.26%), Astralon Restorasi 2 (27.01%) and Astralon Restorasi 3 (4.37%) and a decrease for Plastik Sablon samples (32.59%). There was an increase in tensile strength values after aging in Mylar (4.30%), Plastik Sablon (10.43%), Mika Asahi (5.42%) and Astralon Restorasi 3 (1.67%) samples and a decrease in Astralon Restorasi 1 (2.39%) and Astralon Restorasi 2 (5.84%) samples. GC-MS testing on all double-sided tape samples obtained the most dominant content results are Oxirane, 2-ethyl-2-methyl-, Cyclopentane, methyl- and 3-methylpentane.
