There are three standard types of carrier tape material: paper, polystyrene, and polycarbonate.
Paper is the best option for those working with small passive components. These components may include capacitors and resistors. The components carried by paper carrier tape do not need a lot of protection from being jostled around when they are transported on the reel.
Polystyrene is one such plastic carrier tape material. It offers moderate protection that works well for many components. The pockets on the tape are both deeper and firmer than those on paper. It's a top choice for some thicker components and generally is extremely affordable. Plastic carrier tape with embossed pockets is another, more protective option. It is best for those working with more significant components or those that require more protection from bumping during transport.
However, polycarbonate is the most protective material for carrier tape. This type of tape and reel packaging is essential for tiny and delicate components. The pocket shapes closely hold the components as they run through the assembly process and feed even the tiniest parts onto production equipment smoothly.
