The material of the carrier tape mainly includes two types: plastic (polymer) and paper. The embossed carrier tape is mainly composed of plastic materials. The mainstream in the market is PC (Polycarbonate, polycarbonate) carrier tape, PS (Polystyrene, polystyrene) and ABS (acrylonitrile-butadiene-styrene copolymer resin). Belts, in addition to a small amount of carrier tape prepared from PET, APET and other materials. The stamping carrier tape is mainly prepared from paper materials or PE composite materials.
PC materials are characterized by high mechanical strength, good transparency, good dimensional stability, high glass transition temperature and good heat resistance. The mechanical strength of the PS material is lower than that of the PC material, so sometimes the ABS material is made into a three-layer composite sheet to improve the tensile strength of the carrier tape. The mechanical strength of the PET material is close to that of the PC, but due to the crystalline material, the dimensional stability is poor.
