22 September 2016Polyonics exhibits latest barcode label and tag materialsPolyonics (stall B3) will introduce several new barcode label and tag materials at Labelexpo India. The products include materials for ID and tracking applications in the PCB and hot metal industries. The new XF-731 and XF-735 thermal transfer printable polyimide label materials include ultra-durable topcoats designed to resist harsh highly active fluxes used in the PCB industry. The semi-gloss white top coats produce high contrast, lasting barcode images that resist softening, will not yellow at elevated temperatures and provide high abrasion resistance. The materials also include liners for die-cutting and ultra-strong pressure-sensitive adhesives that resist high-pressure washes. The XF-735 is also ESD-Safe and complies with the IEC 61340 and JEDEC 625B standards for charged insulators used in the proximity of ESD-sensitive devices. Also being introduced are the Polyonics XF-608 and XF-610 barcode tag materials for tracking hot metals. The XF-608 is a 227 µm durable paper laminate that operates continuously at 200 deg C with short term exposures up to 300 deg C. It produces high contrast barcodes with a variety of ribbons and provides increased tear resistance compared with other tag materials. The XF-610 is a double-sided 125 µm polyimide tag material rated for an operating temperature of 400 deg C and short exposures up to 600 deg C. The material provides high tear and abrasion resistances, has a gloss white coating on one side and matte white on the other and is primary tag used to track hot metals from furnace to customer delivery.
