Plastic Container Recycle Codes

 recycleplastic.gifPlastic Container Recycle Codes

Code_1_PETE.gifPolyethylene Terephthalate ( PET or PETE ): Smooth and clear plastic that can be semi-rigid to rigid depending on container wall thickness. Polyethylene Terephthalate is known as "PET", but the recycling code is PETE because PET is trademarked.

Common uses: Plastic bottles for soda, water, food, liquid soap and lotion.

  • Pros

  • Cons

  • Good to fair general chemical barrier

  • Poor chemical barrier for strong acids and bases

  • Good alcohol and solvent barrier

  • Fair moisture barrier

  • Good gas barrier


  • Good moldability


  • Can be sterilized with EtO (ethylene oxide) or gamma radiation


  • Good stress crack and impact resistance at room temperature and above


Code_2_HDPE.jpgHigh Density Polyethylene (HDPE): Translucent, milky white colored plastic. Flexible, but more rigid than LDPE.

Common uses: Plastic bottles for soda, water, food, liquid soap and lotion.

  • Pros

  • Cons

  • Good impact strengt

  • Poor gas barrier

  • Good stress crack resistance


  • Good chemical resistanc


  • Good vapor barrie


  • Excellent resistance to most solvent


  • Higher tensile strength than other forms of polyethylen


  • Can be sterilized with EtO or gamma radiation


Code_3_V.gifPolyvinyl Chloride (PVC): Flexible to rigid plastic that is transparent to yellowish in its natural state. Polyvinyl Chloride is called PVC, but it is also commonly known as vinyl. So the recycling code for PVC just uses the letter V.

Common uses: Clear food and non food packaging, medical tubing and wire insulation.

  • Pros

  • Cons

  • Good for coating

  • Fair water barrie

  • Stable electrical properties

  • Fair stress crack resistance

  • Good oxygen barrie

  • Poor recycling due to chloride residue

  • Good chemical resistanc


  • Can be sterilized with EtO


  • Good impact resistanc



Code_4_LDPE.jpgLow Density Polyethylene (LDPE):  A very flexible, natural milky color, translucent plastic with high impact strength.

Common uses: Plastic bottles for honey, mustard and bread or food bags.

  • Pros

  • Cons

  • Good general chemical resistance

  • Poor gas barrier

  • Excellent chemical resistance against mild and strong buffer


  • Good water vapor and alcohol barrier properties


  • Can be sterilized with EtO or gamma radiation


  • Good stress crack and impact resistance





1682061522841676.gifPolypropylene (PP): A rigid, solid, durable plastic. It is opaque with a grayish yellow color in natural form.

Common uses: Plastic containers for ketchup, yogurt, margarine and medicine.

  • Pros

  • Cons

  • Excellent stress crack and impact resistance

  • Poor gas barrier properties

  • Excellent moisture barrier


  • Good oil and alcohol barrier


  • Good chemical resistance


  • High melting point - good for hot fillin


  • Can be sterilized with EtO or autoclaving



1682061744158810.jpgPolystyrene (PS): A transparent, rigid and glass-like polymer.

Common uses: Packaging for CDs, aspirin bottles, cups, plates and disposable cutlery.

  • Pros

  • Cons

  • Light and heat stable

  • Poor barrier properties

  • Good resistance to inorganic chemical

  • Brittle in its general purpose form

  • Good stiffness in both foamed & rigid forms


  • Good impact and stress crack resistanc


  • Can be sterilized with EtO or autoclavin


  • Foamed PS - Low thermal conductivity & excellent insulation


Code_7_OTHER.gifOther Plastics: The miscellaneous classification includes plastic that may contain multiple layers of different types of materials, like the above plastics. Some plastic that fall under this code are polycarbonate, Polytetraflouroethylene and Teflon.

Common uses: Multiple gallon water bottles, juice bottles, oven-baking bags and custom packaging.

  • Pros

  • Cons

  • Combined characteristics from multiple plastics can create an improved material

  • Plastic bottles and containers from this group are not easily recyclable
