the research and development team at tcl packaging developed new microperforated printed lidding films to create optimum conditions for soft fruit.the films permit precise gas and moisture transmission rates, effective tray sealing and maximum protection from contaminants for the contents, frequently an issue for fruit with standard holepunched lidding films.enlargetechnical director markus jarvstrom explains &ldquofruit lidding film is often perceived as a relatively simple product but developing it is a complex task. it requires an indepth understanding of the dynamic interactions established between the product, the atmosphere generated within the package and the package itself &ndash and all the possible variants.&ldquothe transfer of packaged soft fruit from ambient to chilled storage also presents an additional technical challenge for lidding film to avoid misting. we also encourage preprinting because many growers are not aware that a secondary labelling process can impede the lidding film performance and affect their product&rdquoa new rofinbaasel laser scribing unit was recently installed at tcl&rsquos new telford factory to facilitate quicker delivery of printed, perforated lidding films for the new soft fruit season.the company is offering shelflife trials of the new films for growers and packers.
