Traditional creasing profiles were designed for a time when board was made from paper containing mainly virgin fibre. Today’s board contains a high percentage of recycled content and is made with lightweight liners. Pairing traditional creasing profiles with recycled board can lead to rolling scores, manufacturer’s gap variation, and trouble achieving a consistent crease line.
The new G3 system from Sauer System was specifically designed to improve creasing and folding when converting recycled board and other challenging materials.
While traditional male profiles force the board to stretch around the insert during creasing, leading to rolling and cracking, the G3 male profile incorporates specific geometry which conditions the board and provides relief for the inside liner.
The result is improved folding, a proven reduction in manufacturer’s gap variation and a higher quality finished product.
The system features a replaceable tapered insert, available in various heights depending on the application.
