I wondered what's the appropriate term for the hard plastic cover one so often sees protecting certain products. I took a photo in order to visualise my meaning:


Thank you for your help!

  • 'Hard plastic cover / protective packaging' works. May 9, 2018 at 13:16
  • 'Molded plastic packaging' (See images here: google.com/…) May 9, 2018 at 13:46
  • Are you referring to the translucent pieces of hard plastic protecting the tips of the knives, or the transparent plastic around all the knives?

  • @Lawrence referring the the overall packaging, not the plastic tips

If the plastic is folded back on itself and then sealed at the edges, you may have a clamshell package. If the plastic is bonded to a piece of cardboard, then it’s a blister package, as mentioned by Jim Mack.


  • I gave a plus 1 but after some thought I think more caution might be needed - 'sealed clamshell' perhaps?

  • I looked at serpapackaging.com to see if there was a trade name. It's a very interesting site, since they have videos of all their packing machines in operation. I didn't find a specific device for the heat-sealed clamshell.

This is often called a blister pack as seen at this Wikipedia page.

    Blister packs are specifically for multiple instances of small single capsules of a medication. The OP is asking about the packaging of a medium sized manufactured consumer item, like the knives as shown or batteries or small electronics or lots of things, annoyingly difficult to open.

  • @Mitch - That's one use. Look at the portion of the Wiki article labeled "Consumer goods".

  • @mitch, the "blister pack" term generally applies to any plastic shell with depth to hold the product, against a flat back. The pill conformation you describe happens to be one kind of blister pack. +1 to this answer, as it would have been my answer

  • @user662852, Jim: I had only ever thought of blister packs as those things like for medications that had little bubbles, like blisters, that you push a little pill out of, not for the large things.
