Description: Valmet will supply a new off-machine coating machine to Oji Papéis Especiais (OPE) in Piracicaba, Brazil. With the new off-machine coater PC4, OPE is seeking to increase thermal paper production capacity and strengthen its competitiveness globally, focusing on the Brazilian, South American and North American markets.

Details: Valmet’s delivery for the off-machine coater will include a new OptiCoat Layer curtain coating station, which gives a very good profiling and coverage even with thin layers, thus the amount of expensive thermal coating color can be kept low. The delivery includes also a re-reeler, an OptiCalender Soft calender, an OptiReel Center reel and OptiDry Coat coating air dryers. The air-drying capacity and their temperatures have been carefully calculated and optimized for high quality thermal paper. The delivery will also include a supply system for the curtain coater unit.
The start-up and the further optimization of the new board machine will be supported remotely from Valmet Performance Center utilizing the latest Industrial Internet solutions. Data-based and proactive remote support is a fast and efficient way to ensure that the optimal thermal paper quality is reached, and the machine is meeting the planned start-up curve. The automation delivery will include Valmet DNA automation system with machine controls and condition monitoring. It also will include Valmet IQ quality management system with a full-scale quality control, moisturizing profiler, and machine vision systems consisting of web monitoring (WMS) and web inspection systems (WIS). The 4,200 mm wide (reel) off-machine coater will produce thermal grades in the basis weight range of 44-55 g/m². The design speed is 1,200 m/ min.
Start up: The start-up of the new off-machine coater is scheduled for November 2021.
