Matte finish creates newsprint look
While glossy film is the norm for snack foods, a fish & chips snack bag from Burton's Biscuits in England features an alluring matte finish that stands out in the snack aisle.
Nostalgic graphics depict old newspaper wrappings around fresh product harking back to the earlier age of street vendors. "The design cleverly contrasts black-and-white crumpled newspaper images with a full color illustration of the three-dimensional fish and chip shapes within" says Brian Mills group packaging development manager for Burton's. The new product and package was launched in April '97. The 1.6-mil structure consists of a clear oriented polypropylene coextrusion reverse printed in gravure in seven colors and adhesively laminated to a metallized OPP coextrusion. It's converted by Bonar Teich represented in the U.S. by H&N Packaging (Chalfont PA). In detail the structure from the outside consists of an outer OPP matte layer treated for heat sealing/an OPP core/an inner layer of OPP treated for printing/ink/adhesive lamin<> ation/an outer metallized layer of OPP/another OPP core/an inner OPP layer treated for heat sealing. The core layers of OPP in each coextrusion are designed to resist melting during heat sealing which adds to the structure and integrity of the film says the converter. Such heat-sealing properties are necessary on both the inner and outer layer since the longitudinal seal is an overlap seal and not a fin seal. The individual OPP coextrusions are from Hoechst represented in the U.S. by Hoechst Trespaphan of America LLC (Winston-Salem NC). Mills says the matte film costs "about the same" as traditional glossy stock. Burton's in Bracknell about 40 miles west of London packages the product for upscale retail chain Marks and Spencer. That firm sells the product in England and several European countries.
