There are two kinds of materials for carrying tape: paper and plastic. At present, paper tape is only applied to passive components because of its thickness limitation and poor electrostatic protection and moisture-proof performance.—materials of the Carrier tape

There are mainly two kinds of plastic carrier materials: PC polycarbonate and PS polystyrene. Please refer to figure 1 and table 2 for their performance comparison. materials of the Carrier tape

As an engineering plastic, PC not only has low shrinkage and high tensile strength, but also has the characteristics that the precipitation index of corrosive ion impurities is much lower than PS. these characteristics make the carrier of PC meet the requirements of high precision and high tensile resistance, It can also meet the process requirements of the purification workshop.–materials of the Carrier tape

After carbon addition, PC raw materials have high anti-static performance, so now most discrete component manufacturers use PC carrier belt. Of course, when transporting large components without high-precision carrier belt, PS carrier belt is also a good choice because PS material is cheap.
