PIERCING AND MICROPIERCING

The micro-piercing process to which polyethylene film is submitted, is an accessory processing that can be carried out on film in reels. Indeed, through a special machine, the film is unrolled and passed through a sophisticated system of tiny heated needles for drilling. The procedure takes place under strict monitoring that is deemed necessary to prevent reel damage, and consists in controlling drilling speed and needle temperature. Both criteria ​​must be constant to ensure maximum drilling quality.
