The brand new AMUT DOLCI EXTRUSION line, supplied to an European customer, will produce PA-PE film to be converted into vacuum pouches/envelopes or trays for sliced foodstuff. mances in terms of efficacy, efficiency and flexibility. The absolute absence of “curl-problem”, the high transparency of the film and the in-line edge trims recovery system to re- duce waste at minimum represent fur- ther competitive margins, especially for vacuum pouches production. Line composition : First section: cast for PA barrier Consisting of : extruder with gravimetric F ood application needs a multilayer film with barrier properties against gas, fats and flavourings. The line configuration includes 3 secti- ons: two with flat die (cast) – one for barrier resins (PA) and one for polyolefins (LDPE, LLDPE, yonomers) – and a central- ly placed lamination section where the two formed films are coated. A barrier film with net width of 1.800mm and PA / Primer / Pe+Pe / Pe+Pe+ Pe formulation is obtained. The roll diameter is 800 mm and the total output is 600 up to 900 kg/h depending on thickness. Even if the formulation of produced film is quite simple, the line has great perfor- 26 Film Extrusion Extrusion 6/2018 Cast-Lamination Line with 3 Sections for the Production of Barrier Film (PA-PE) dosing system, automatic T-die, chill roll with 3 heated calenders, vacuum box, rolls unit for film stabilization, water based Primer-Coating station with re- verse roll system and hot air dryer, Coro- na treater.
