Blown Film Extruder is used to by the plastic converting industry to manufacture plastic film. Plastic converting is usually referred to the manufacturing process where plastic resins are processed to plastic packaging material like plastic bags, plastic geomembrane film. Extrusion is the first step of the plastic conversion, whereas the resins are processed to rolls of plastic film. One of the technologies used for plastic converting is the blown film extrusion.
Blown film extruder is recognized by the wider public by it's several meter tall tower. The tower is the part of the equipment where the film blowing takes place. The resin is melted at the bottom of the equipment and than transformed to film. Then the film is led up to the tower. The main function of the tower is while the film is run through the tower from the bottom to the top, there is a controlled cooling airflow, air-blow applied to the film. The controlled cooling of the film is essential to produce film of consistent homogeneous quality.
Blown film equipment can be categorized depending on the number of layers the film, which the machine produces, consists of. Plastic film are commonly used for packaging and insulating goods that are sensitive to light, heat and other external factors. The properties of the plastic film can be greatly engineered by layering plastic films together, (this what the co-extrusion is referring to) creating the so called barrier films. In some certain barrier film technologies plastic film is co-extruded with non-plastic material.
Market info
Among distillate fuels, the trend in recent years has seen the proportional demand for heating oil decreasing, as usage of liquified petroleum gas (LPG) has increased. [1]

Heating oil futures contracts trade in units of 42,000 gallons, which is the equivalent of 1,000 barrels. Prices are based on delivery in New York City harbor, the principal cash market trading center. The heating oil futures contract is also used to hedge diesel fuel and jet fuel, both of which trade in the cash market at an often stable premium to heating oil futures.
