They are then transported by truck, train or ship to services the place, underneath superior heat, an extruder designs the plastic right into a slender film. The film is flattened, then Slash into pieces. Next, it is sent to manufacturers for being made into bags. The plastic bags are then packaged and transported all over the world to vendors. When polyethylene might be reprocessed and used to make new plastic bags, most plastic bags are only used a couple of times before they finish up currently being incinerated or discarded in landfills.
