ampac, cincinnati, oh, introduced flexi foilfree hb, an ultrahighbarrier film technology that can achieve moisture, oxygen, and vapour barrier properties approaching aluminium foil laminates, without the use of foil, when incorporated in a laminate. the laminates are said to provide improved packaging yield and lighter weight versus comparable foil substrates, yielding lower greenhouse gases and requiring less energy consumption in manufacturing and distribution.the film laminate is economical a two or threeply flexi foilfree hb composite will provide comparable o2 and wvtr barrier properties than more traditional three and fourply foil based laminates according to the company, realizing improved material cost.packaging applications for flexi foilfree hb barrier film include the diagnostics, drug delivery, biotech, and medical device markets and packaging both dry and liquid food products such as cake mixes, powdered soups, dips, gravies and liquid cheese sauce.flexcrack and puncture resistance properties are significantly improved in composites when used in place of foil, while also providing easier &ldquotearopen&rdquo properties over foilbased substrates.
