Looking for Powder Filling Company United Kingdom

I looking for a company in Turkey , who can help me pack my food in paper bag
full load 20 feet container , swap 25kg corn flour into 3kgx4 (1 carton 12kg)
I got a food vendor , but they can't fill in a small kraft bag (3kg x 4 bags , 4 dags per carton) , they can only fill in 25kg big bag . So I need a filling company (for food grade standard)
