What Are Plastic Sheets Called? The Ultimate Material Guide
In our daily operations at Prime manufacturing plastic components, we process over 50 different grades of plastic sheets - these flat plastic materials are collectively called plastic sheeting or plastic stock sheets, but their technical names vary tremendously based on material composition, manufacturing process, and intended applications, with each type offering distinct properties that make them suitable for different industrial uses from protective coatings to precision machine parts.
Snippet paragraph: Plastic sheets are most commonly referred to as plastic sheeting, plastic stock, or plastic panels in industrial contexts, with specific names like acrylic sheet, polycarbonate panel, PVC film, or HDPE board used to describe particular material types - thickness typically determines whether it's called sheeting (thinner) or sheet/plate (thicker), with these versatile materials used in everything from packaging to construction.
The naming conventions hide surprising complexity - let's peel back the layers.
What Determines the Names of Plastic Sheets?
