If you look closely at plastic products around you, you will notice that their surfaces can feel very different. Some are smooth and glossy, some have a soft matte texture, and others feature patterned surfaces for better grip. These differences are not accidental—they are the result of plastic finishes. Finishes on plastic affect much more […]
