Behind the packaging

 

Once the metal is processed it is cut to size and chemically treated.  It then goes through a sterilization process before it is printed with the appropriate label.

From there it gets fed into a machine where it is cut to size and formed.  It is now in the shape of a tube.  It gets injected with product and capped with a plastic top.  Once capped and packaged in a box, it is sent to distributors, who ship it to stores.

You purchase it and once it is put into use, you squeeze the product out of it, as needed.

When the tube is empty, its shape is now flat, and you discard the container.  Trash collectors take it from your residence to a local landfill where is goes back into the earth, where the original metal was mined.

Quite an adventure.
