Mystery of the Internal Vibration

Entry for May 29, 2006


To assist recycling of disposable items, the Plastic Bottle Institute of the Society of the Plastics Industry devised a now-familiar scheme to mark plastic bottles by plastic type. A recyclable plastic container using this scheme is marked with a triangle of three “chasing arrows”, which enclose a number giving the plastic type.
The resin identification codes:

  1. PETE: Polyethylene Terephthalate – Commonly found on: 2-liter soft drink bottles, cooking oil bottles, peanut butter jars.
  2. HDPE: High Density Polyethylene – Commonly found on: detergent bottles, milk jugs.
  3. PVC: Polyvinyl Chloride – Commonly found on: plastic pipes, outdoor furniture, shrink-wrap, water bottles, salad dressing and liquid detergent containers.
  4. LDPE: Low Density Polyethylene – Commonly found on: dry-cleaning bags, produce bags, trash can liners, food storage containers.
  5. PP: Polypropylene – Commonly found on: bottle caps, drinking straws
  6. PS: Polystyrene – Commonly found on: packaging pellets or Styrofoam peanuts, cups, plastic tableware, meat trays, take-away food clamshell containers.
  7. OTHER: Other – This plastic category, as its name of “other” implies, is any plastic other than the named #1–#6, Commonly found on: certain kinds of food containers and Tupperware.
