Film processor Dallas Plastics boosts productivity with new air ring

Film processor Dallas Plastics boosts throughput by as much as 40% by retrofitting a new air ring—without the need for IBC.

Output increases equal to that of adding internal bubble cooling without the “expense and headaches” associated with IBC. That’s how Miguel Sanchez described his experience following the installation of a new air ring at Dallas Plastics Corp.’s blown-film plant in Wentzville, Mo.

Sanchez manages that plant, one of three facilities operated by Dallas Plastics, which was established in 1989.

The company ( specializes in converter-grade films for printing, laminating, and automated packaging, and offers a wide range of specialty films such as narrow-width layflat tubing, critical-tolerance films, non-scratch LDPE, and hightensile-draw tape for drawstring bags.

 Its films are used in a wide variety of markets that include food, medical, agricultural, retail, automotive, aircraft, and electronics.

Like most PE film processors, Dallas Plastics is regularly on the lookout for technologies to increase capacity.

Addex introduced the Intensive Cooling Air Ring in 2016 (see  June ?16 Close-Up). It utilizes up to four stacked cooling elements with a surrounding enclosure, all topped by a conventional air ring.

But Addex ( quickly realized that this technology was  probably better suited for brand-new lines, so at K 2016 it showed a scaled-down version specifically targeting the retrofit business.

Dallas Plastics ordered two of the new air rings, one for the  Missouri plant and the other for its facility in Longview, Tex. In Missouri, the new ring was installed last May on a 10-in. die.

Sanchez adds that Dallas Plastics has on order a third Intensive  Cooling Air Ring, which will be installed early this year on a 12-in. line at its headquarters facility in Mesquite, Tex.
