An Avery Dennison Hanita Original
We pioneered the development of ultra-high barrier laminates for VIPS in the 1990s. More recently, the unique in-vacuum metallization processes we’ve developed have enabled production of metallic barrier layers that allow gas and moisture permeation well below any similar product in the industry*, while keeping the thermal bridge effect very low.
A hybrid solution for challenging applications
An effective option for some fiberglass core or high temperature applications is a hybrid "combination envelope" — Avery Dennison Hanita aluminum foil laminate on one side of the VIP's bag, with Hanita ultra-high-barrier metallized films on the other side of the bag. This combination envelope dramatically decreases the effects of the thermal bridge and substantially reduces moisture vapor and oxygen- and nitrogen- molecule gas permeation compared to envelopes with metallized films only.
