New Plastic Resins begin as various virgin Chemical Components that are mixed to make many different types of Plastic Resins. The Plastic Resins are Extruded as Plastic Tubes. The Plastic Tubes are cut into particle size Plastic Pellets and bagged. The bagged Plastic Pellets are procured by Plastic Product - Production Suppliers.
Re-grind Plastic Resins begin as Discarded Plastic Products. Discarded Plastic Products are separated according to the type of Plastic Resin it is.
Many different types of Plastic Materials are used to make many different types of Plastic Products for many different types of Product Applications. In the Plastic Injection Molding cycling process, Thermo Plastics are used. Thermo Plastics are Plastic Resins that can be Re-cycled. Thermo Set Plastics are Plastic Resins that can not be Re-cycled but can be Re-purposed. To keep track of all the of the many different types of Plastic Products that are made of Thermo Plastics, (Plastic Identification Codes / Resin Identification Codes) are used.
