Consumers use plastic in some form every day—from soda bottles to laundry pods, single-serve brew cups to bread wrappers and ties, car fobs to sunglasses; plastic is everywhere. It is also found in our garbage. The Environmental Protection Agency reports that In 2014, plastics made up 33 million tons — or almost 13 percent — of the municipal waste stream. The amount of plastics that actually end up going in recycle varies by type, but overall, only 9.5 percent of all plastic gets recycled. The most popular Type of plastic in the world is polyethylene(PE) and polypropylene (PP), and one of its most common forms is a thin film that is used to make many shrink wraps, various forms of packaging, and the ubiquitous plastic bag.
Polypropylene (PP), also known as polypropene, is a thermoplastic polymer used in a wide variety of applications. An addition polymer made from the monomer propylene, it can be produced in a variety of structures giving rise to applications including packaging and labeling, textiles, plastic parts and reusable containers of various types, laboratory equipment, automotive components, and medical devices. It is a white, mechanically rugged material, and is resistant to many chemical solvents, bases and acids.
Polyethylene or polythene (abbreviated PE; IUPAC name polyethene or poly(ethylene)) is the most common plastic. The annual global production is around 80 million tonnes. Its primary use is in packaging (plastic bags, plastic films, geomembranes, containers including bottles, etc.). Many kinds of polyethylene are known, with most having the chemical formula (C2H4)n. PE is usually a mixture of similar polymers of ethylene with various values of n.
Plastic bags and plastic wraps make up the category “plastic film.” This includes everything from grocery and bread bags to shrink wrap and paper towel film. In 2012, the recycling of post-consumer plastic film surpassed one billion pounds – up 56% since 2005.
With the development of society, plastics are becoming more and more common in our lives. However, more and more waste plastics have caused severe white pollution over the coming months. Therefore, recycling of waste plastics has become increasingly important. The recovered plastics are not close to new life, and they can also bring huge profits to recycling factories.
Under this trend, plastic recycling machinery is becoming more and more important. Yurefon Machinery is committed to providing high-quality PP PE plastic film recycling machinery, help customers get return from the plastic recycling industry and contribute to the protection of the environment. Line Flowing chart of the PP PE plastic film crushing washing drying machine:
1.Belt Conveyor: The materials go into the crusher by the crawler belt, which is moved by inside scroll wheel.
2.Crusher: Crush the material.
3.Screw Loader: Put the flakes into the Hot washer to clean.
4.Hot Washer: If the bottle is very dirty, like oil, sand, it must be use hot washer.( optional)
5.Screw Loader: Put the flakes into the High-speed Friction Washer to clean.
6.High-speed Friction Washer: After crushing material from enters the mouth, through the high speed on the axis of the blade flap and spray water to the common function of good cleaning effect.
7.Floating Washer : It used in cleaning pet flakes, make the flakes cleaner and whiter. Also is the necessary equipment of the bottle and bottle cap. 8.Screw Loader: Put the flakes into the dewatering machine.
9.Dewatering: Remove the water from the flakes, moisture content is less than 6%.
10.Drying Pipeline1: To make the moisture more lower.
11.Drying Pipeline2: To make the moisture more lower.
12.Silo: Storage and packing PP PE film materials.
