Silos for storing different resins. Gravity and pneumatic conveyors transport the raw materials to the extruders from the silos. High precision gravimetric dosing and mixing units feed virgin resin, recycled resin, master batches, edge trim, and additives to the extruder.
Optimized twin screw extrusion with the shortest residence time. Energy saving vapor heating system provides a homogenous surface temperature on all extrusion melt pipes. All twin screw systems for pet with edge trim flakes feeding. Fast change over feedblock for different layer configurations or multi-layer die.
Sprayed-water or spiral type chill roll with backlash-free drive. High level prolonged water bath for BOPP. Advanced pinning systems with air knife or electrostatic band.
Film is first oriented in machine direction. Cast film is warmed to optimum stretching temperature in the pre-heating zone. Individually driven rolls with energy saving vapor heating technology for PP and pressur water for PET. Multi-gap stretching configuration for PP and PET access for maintenance and cleaning.
High speed, fully flexible chain track system performs the transverse stretch. Driven inlet and outlet sprockets for reduced clip friction. Clean TDO heating by gas or oil. Advanced oven concepts to save energy by means of heat recovery systems.
Easy automatic threading of film as it enters the PRS Directly driven rolls, high precision X-ray measurement combined with advanced edge cutting system to measure, trim and treat the surface of the film.
Constant winding angle and perfect control of winding ensure wrinkle-free jumbo rolls up to 8700mm width (or more on request).
Storage and staging of jumbo rolls for other process steps: Slitting, Metallizing, Packaging. etc..
Advanced but easy-to-operate process control for entire. production line.
