High Density Weekly Pre-Portion Bags are made of our high density polyethylene (HDPE) which is a very durable and flexible material.  Operators pre-portion their food and use the food rotation system to:  Save Money:  ensure the exact portion and subsequently the same food cost every time.  Save Time:  operators will sell plates faster during busy times and turn tables quicker.  Build Consistent Portions:  customers want the same portion every time.  Practice Food Safety:  improperly stored food is one of the leading causes of a food-borne illness.
