Raw materials (polypropylene in granules) are dried and mixed in a special machine with dyes and other additives. The main additive is calcium carbonate, thanks to which the bags acquire the desired density and rigidity. If white bags are produced, calcium carbonate is better for this;
The resulting mixture enters the extruder, where it turns into a homogeneous hot mass;

Просушивание и смешивание сырья. Гранулы полипропилена смешивают со всеми необходимыми добавками и красителями. Нужную жесткость и белый цвет придает мешкам карбонат кальция. Готовую смесь подают в экструдер;
Горячий полипропилен пропускают через специальную насадку. После охлаждения получается тонкая плёнка, которую режут на нити нужной толщины. После закалки их вытаскивают, чтобы намотать на катушку;
