High Barrier Advancements
Vacumet's Plasma treating capability in conjunction with proprietary processing techniques has acheived barrier improvements in excess of 400% since 2003.
 With minimal impact on final product pricing, Vacumet can now supply plain packaging grade PET and acheive oxygen barriers consistently less than .01 cc/100 in²/day.
Prior to these advancements this level of O² barrier was achievable, but at much greater cost of specialty base films. Now equipment, base film and specialized process conditions combine to produce a low-cost high barrier product, ULTRA BARRIER-MET®. See our detailed Product Specifications for this high barrier product as well as our standard offerings.
Much of the technical work done to achieve higher barriers on plain PET films came from Scholle Packaging's high barrier needs for the liquid packaging market.
The Bag-in-Box liquid packaging market requires high barrier and low-cost productions. Not only did Vacumet's enhanced process conditions improve the metallized films barrier, but the improved metal adhesion characteristics improved the degradation of barrier through the multi-step lamination process at Scholle. This resulted in an end product that greatly exceeded expectations in the end user market.
