Reclosable mailer highlights Redken hair colour

For a market defined by image, a flexible film "envelope" containing promotional billboards for Redken's Colour Fusion hair colour line (13) distributed to beauty salons last September was the epitome of chic. A 20 x 13-in. gravure-printed pouch with a zipper closure, the mailer gives new style to marketing materials typically enclosed in plain paper or plastic wrap.

Says Jane Dirr, president of Specialty Films and Associates, Inc., which received a silver award in packaging excellence for its converting of the project, "This package presents an entirely new way to view mailers and the part they play in sending a message about a company's philosophy and presence. The package allows the mailer to be the marketing tool."

Graphics, designed by Redken's in-house creative group, provide a surrealistic feel. Gravure-printed on a metallic polyester laminate, they present a head-and-shoulder view of a young model, awash in shimmering shades of burnt orange and gold. Sparse but striking silver-metallic type displays the product name, while the Redken logo is prominently depicted in the mailer's lower right-hand corner. Enclosed are four "billboards" to be used throughout the salon to promote the Color Fusion line.

Through the inclusion of a press-to-close zipper from Minigrip across the pouch top, the mailer becomes reclosable and, in effect, reusable. "The idea was that when the pouch was opened by the salon, it would stay intact and could be used for storage," explains Dirr, "Whereas, if the pouch was heat-sealed, it would have to be cut open, and if a tear-notch were used, the pouch could become torn during opening."

The film construction-a 48-ga metallized PET laminated to a 3.5-mil LDPE-was chosen because of its ability to achieve the aesthetics desired for the application. In addition, its ease of handling characteristics were a factor, as the 28,000 mailers were filled manually at Redken's Hebron, KY, distribution center.

The job, which uses four process and three line colours plus an overprint varnish supplied by Sun Chemical, was printed on 10-colour Schiavi gravure press and laminated on a Comexi solventless laminator. Says Dirr, the mystical nature of the pouch's images made the job especially challenging, "as it was very difficult to identify on-press if there were any print issues."

While clearly a more expensive alternative to the standard paper or clear film envelopes usually used, the zippered pouch, notes Buddy Schnapp, Redken's senior director of purchasing, is worth its weight in gold. "Our customers are always looking for more image-type pieces," he says. "This mailer created more of a 'buzz'; there was much more excitement expressed by the salons when they received it."

Prolific "Reclosable" Bags - Fun

There are reclosable bags on just about anything that you might want to buy these days. You can get cheese with reclosable bags, deli meats with their own stay fresh seal, and lots of other food type products.

When I needed more socks my wife purchased a package and brought it home. I didn't look at it right away, but when I did I noticed that I too came with a resealable bag. I'm not sure, but it could be so that when I take a pair out I can reseal it and the remaining pairs would stay fresh. There are of course other explanations:
