Web Direction Series

Preco Web Direction Flexible Packaging Machine

Designed for a Variety of Flexible Packaging Features

The Web Direction (WD) series machines are primarily utilized for micro-perforating, venting and controlled depth scoring applications. These machines are designed to be integrated inline with slitter rewinders but can also be adapted to laminators and extrusion lines. The WD series machines are built to handle web widths up to 2000 mm (79 in.) and they can have up to sixteen processing heads.

Applications

Micro-Perforating - Modified atmosphere packaging (for burst protection and moisture release)
Web Direction Scoring - Straight line, controlled-depth scoring in the web direction (for easy-open features)
Microwave Venting - Controlled depth and/or through-cut line segments (dashes/slits)

Multiple modules with maximum flexibility.

The WD Series machines can be designed and integrated into production lines such as laminators, extruders or can be set up off-line on a rewinder or slitter. Systems are adaptable with web widths up to 1600 mm (62.99′′). This series offers precise laser scoring for easy-open packaging.

Preco's beam compression technology is used to produce consistent geometric-shaped holes at processing speeds up to 2500 ft./min. This is the fastest perforating head in the industry.
