Thin-Film High-Barrier Technology for New Type Packaging Material

Food Packaging material requires an excellent barrier ability to humidity and oxygen. SiOx barrier thin film deposited on high polymer substrate can compare beauty with aluminum foil in the barrier quality,even more Si Ox barrier thin film is obviously allowing microwave permeating directly and it also provide a chance for merchant to vision their production in shelf life. SiOx film as barrier packaging material is becoming a high light. The current status and research progress of new type high barrier thin film packaging material were overviewed and production technology was introduced. The various influencing factors were discussed, including background vacuum, reactive gases, and pretreatment of the substrate surface and properties.
