There are several trends that the Italian shrink sleeve specialists Finpac identifies for the labelling market. “For PET bottles, there is a growing demand for perforated films — vertically and/or horizontally. Removing them makes it easier to recycle the bottles after they have been used,” reports Enrico Danovaro, Commercial Director Finpac.
Paolo Gobrili, the company’s sales manager, is also seeing increased demand for reducing label thickness. Finpac has already completed a successful series of tests with label thicknesses of 20 microns.
At the Brau Beviale; Finpac featured their latest technological innovation with an autosplicer for sleeve reels. It consists of reel-holders with an automatic joining system for high-speed sleeving lines, up to 72,000 bph which can guarantee continuous production up to 40 minutes without any intervention by machine operators (based on a 500 ml PET bottle configuration with a full body sleeve label having a cut length of 172 mm fed by n. 2 autosplicers).
The drawer reel holder combined with a jointing system between the different reels, – up to 4 reels of 1,000 m – is specifically designed to guarantee flexibility, speed, reliability and high productivity combined with an intuitive and easy-to-use logic.
The automatic splicer offers a system with four drawers for preparing the joint “omissis”. The “omissis” joint is automatically moved to the correct position eliminating any human error and eliminating the need for an operator on the line.
Consisting of a sturdy, all-steel structure, and moveable drawers holding up to four reels which ensure a continuous label flow the system is stated to guarantee a simple, fast and safe preparation of the sleeve reels by the operator.
Each of the reel-holding drawers is composed of a contrast roller, a support bar for preparing the joint and a reel locking bar that serves to keep the reels in position while the operator applies the adhesive without loss of line-speed.
Once the adhesive has been placed, the operator needs only to confirm the preparation by pressing a button. The system automatically moves the prepared junction to the correct position “omissis”. Once the cycle is activated, the simultaneous action produces an accurate join between the coils in a few seconds and the end result is a real overlap between the ends.
