BOPET Films (Biaxially Oriented Polyester)
technoPET offers an extensive portfolio of BOPET (Biaxially Oriented Polyethylene Terephthalate) films for packaging converters, printers, and industrial laminators. Engineered with high dimensional stability over broad temperature ranges, our BOPET films are available in plain, corona-treated, chemical-coated, and vacuum metallized variants. They serve as the benchmark outer print and barrier layer for retort pouches, snack packaging, metallic yarn, hot stamping foils, and solar photovoltaic backsheets.
