If the material is high density polyethylene or polypropylene,
5. Design of extrusion type plastic bottles, plastic bottles of cross section should be rectangular or oval, low density polyethylene or other flexible material for plastic bottle, its round cross section as well, such facilitating contents from squeezed out from the plastic bottles.
