PP PE Bottles Rigid Plastic Recycling Machine Line

A plastic bottle is a bottle constructed from plastic. Plastic bottles are typically used to store liquids such as water, soft drinks, motor oil, cooking oil, medicine, shampoo, milk, and ink. The size ranges from very small sample bottles to large carboys.

High-density polyethylene (HDPE) is the most widely used resin for plastic bottles. This material is economical, impact resistant, and provides a good moisture barrier. HDPE is compatible with a wide range of products including acids and caustics but is not compatible with solvents. It is supplied in FDA-approved food grade. HDPE is naturally translucent and flexible. The addition of color will make HDPE opaque, but not glossy. HDPE lends itself to silk screen decoration. While HDPE provides good protection at below freezing temperatures, it cannot be used with products filled above 190 °F (88 °C) or products requiring a hermetic (vacuum) seal.

Low-density polyethylene (LDPE) is similar to HDPE in composition. It is less rigid and generally less chemically resistant than HDPE, but is more translucent. LDPE is used primarily for squeeze applications. LDPE is significantly more expensive than HDPE.

Polypropylene (PP) is used primarily for jars and closures and provides a rigid package with excellent moisture barrier. One major advantage of polypropylene is its stability at high temperatures, up to 220 °F (104 °C). Polypropylene is autoclavable and offers the potential for steam sterilization. The compatibility of PP with high filling temperatures is responsible for its use with hot fill products. PP has excellent chemical resistance, but provides poor impact resistance in cold temperatures.

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 bottle rigid plastic recycling machinery, help customers get return from the plastic recycling industry and contribute to the protection of the environment.

硬料


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 floating washing tank to clean.
4.Dewatering: Remove the dirty water from the flakes after crushing, to relieve floating washing tank cleaning pressure.
5.Hot Washer: If the bottle is very dirty, like oil, sand, it must be use hot washer, the water inside better about 90 degree, and with the cleanser, it will have very good washing effect.
6.Screw Loader: Put the flakes into the High-speed Friction Washer to clean.
7.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, it also can wash off the cleaner in hot washing machine.
8.Floating Washer: It used in cleaning PP PE flakes again, to make the flakes have more higher quality.
9.Screw Loader: Put the flakes into the dewatering machine for dewater.
10.Dewatering: Remove the water from the flakes, moisture content is less than 3%.
11.Drying Pipeline: To make the moisture more lower.
12.Silo: Storage and packing PP PE flakes materials.
13.Electrical Control Cabinet: To control the whole recycling machine line.
