Colines has developed fully recyclable stand-up pouches based on an all-PE laminate pairing a 70 micron PE-barrier film with a 25 micron cast MDO-PE printable web. The barrier film was produced on a nine-layer Polyblown blown film line that the company plans to run live at K 2025, and the cast MDO-PE component was stretched at a ratio of 4.8:1 using ExxonMobil resins. Long-time partner Sumer Plastik handled flexographic printing and pouch making, delivering finished pouches that will be on display at K 2025. Colines reports that the latest MDO-PE film demonstrates consistent performance, favorable optical properties and robust processability. Nicola Lombardini, R&D manager at Colines, commented: "We are truly excited about the outstanding results achieved with our MDO-PE film, thanks also to the significant progress made in our technology. The performance consistency, optical properties, and processability clearly highlight the advantages of our latest developments."
From the converter’s perspective, Sumer Plastik underlined ease of handling and process stability. Company owner Mustafa Tacir stated: "The film proved to be extremely easy to handle and to process, with parameters very similar to BOPP film and zero issues during the converting process. Moreover, the quality of the cast MDO-PE film turned out to be far more stable and consistent compared to the same film produced with blown technology."
The 70 micron PE-barrier film was extruded on a Colines nine-layer Polyblown blown film line, and the 25 micron cast MDO-PE print web was combined to form the pouch laminate. Printing was performed on a flexographic press by Sumer Plastik, which also executed pouch conversion. The pouches will be showcased at K 2025.
