What is the smell from the new plastic storage box

  1. Nov 4, 2018 #1
    It's a tool storage box, probably made of PP (According to the label)
    When its lid opened, quite an obvious (but not very strong) smell coming out
    ,what it could be? vaporized form of plastic????

    A plastic can't evaporate because the polymer molecules are too large for that. However, a new plastic material can probably contain some traces of small-molecule volatile organic compounds it was synthesized from.

    Plasticizer ? Mold-release compound ?
  5. Nov 4, 2018 #4
    That would be my guess, phthalates are common plasticizers

    Almost all plastics outgas VOCs--some more than others. PVC is notoriously known for its outgassing smell, especially new shower curtains.

    I'd say 'mould release agent', too.
    Foul smell should soon dissipate in a well-aired environment.

    Regret terse typing due to hungry cat protesting unacceptable delay on desk...
