New treatments and materials increase the strength and durability of films.
OptiFlex Squeeze Series
A company offers a series of print-treated 3.7-mil and 3.8-mil flexible polyethylene films specifically engineered for full-squeeze tube applications. The series fulfills the need in the marketplace for a film that conforms to the diameter/radius of tube containers. This combination of film and adhesive yields maximum label and graphic coverage while providing a permanent bond to specific areas of the tube container, such as the crimp and shoulder, and the label overlap. OptiFlex Squeeze is available in a 3.7-mil flexible clear, 3.8-mil flexible clear matte, 3.8-mil flexible white matte, and 3.8- mil flexible silver. The films resist deterioration caused by moisture, humidity, and exposure to product contents. Flexcon, Spencer, MA; 508/885-8200; www.flexcon.com.
A company introduces its latest generation of nylon forming film. Developed from the Bemis ICE process, PET ICE represents a step forward in the processability and formability of medical nylon forming films, according to the company. With its unique layer and polymer composition, PET ICE merges the formability of traditional ionomer films with the strength properties of a nylon coex. The 20ï¿½ï¿½30ï¿½C forming window simplifies machine validation. The film has good pocket retention, which makes it suitable for automatic loading systems. PET ICE film processability allows for cycle speed in excess of 20 cpm. Perfecseal, Oshkosh, WI; 920/303-7129; www.perfecseal.com.
PCTFE Film Laminate
A high-barrier thermoformable film laminate uses 4-mil PCTFE in either Aclar or Vaposhield types. The 4-mil film may be laminated to any standard thermoformable film, such as PVC, PP, Barex, or PETG, to produce a high-barrier clear blister film. This specialty film lamination has applications where ultra-high-barrier qualities and clarity are needed in a blister or packaging application. Sample data sheets for PVC-based, 4-mil high-barrier films may be reviewed in the high- barrier/low-MVTR section of the data sheet on the companyï¿½s Web site.

Pentaclear and Pentaprint
A company offers two new lines of vinyl films with a proprietary Dynox surface treatment. The Dynox treatment provides good ink adhesion for use with UV ink systems for a variety of print and folding-carton applications. Available in rolls or precision-cut sheets, these vinyl films eliminate the customerï¿½s need to apply a primer coat for ink adhesion prior to the printing process as well as a varnish top coating for scratch protection of the ink, resulting in overall cost and time savings. Dynox treatment provides film surface-energy values in excess of 45 dyne/cm, which is substantially higher than untreated vinyl, according to the company. Benefits of Pentaclear and Pentaprint vinyl films include gloss and clarity, good gauge control, dimensional stability, smooth surfaces, and lot-to-lot consistency. The films can be used for all types of printing methods, including offset litho, flexographic, and silkscreen. Dynox-treated films are available with one- or two-sided treatment and a gloss/gloss surface. Klï¿½ckner Pentaplast of America Inc., Gordonsville, VA; 540/832-3600; www.kpafilms.com.
