iPLASMA for Extrusion
Extended shelf-life for substrates has long been demanded in the converting industry. Typically, it is recommended that materials are processed within six months of purchase. But this creates additional expense because of the the logistic demands of internal handling, and the risk of having to scrap a large volume of substrate.
Corona is the preferred method of preparing freshly extruded plastic film for converting. However, regardless of how high the treatment dosage [W·min/m2] applied to the material, it always deteriorates over time. The amount of deterioration depends on several factors, including material type and the additives in contains, and can be measured from minutes, to weeks, or even months.
iPlasma overcomes this problem, because materials can be treated to a high and lasting dyne level that is guaranteed for 12, 18, or 24 months.
