The present invention provides a process for manufacturing a flexible packaging laminates for filling liquids in pouches such as edible oil pouches comprising: -taking granules of polypropylene and medium density polyethylene in the proportion 1-1.5:1.5-2.5 ratio, -melting the said granules at 200/230 deg. C. in 3 layer lawn film extruder to form a co-extruded film, -printing said film by Rotogravure printing technique at 40-60 deg. C., -laminating said printed film with conventional 5 layer co-extruded nylon film at 60-80 deg. C., -curing the said laminated film at 35-45 deg. C. for at least 2 days, -slitting said laminated film to the desired size for using on Form Fill Seal machine (FFS Machine) at temperature 160-180 deg. C. for making pouches to fill liquids such as edible oil pouches.
