ABSTRACT:
A packaging system for encapsulating an article within a solid foam material. An article to be encapsulated is supported on a base. A wall enclosure is disposed on the base to form a mold cavity. At the top of the base and above the article to be encapsulated is a cover. Expandable plastic foam in liquid form is introduced into an orifice of the base and the expandable plastic foam advances through a passageway in the base and is discharged from an orifice in the base into the mold cavity to encapsulate the article. The foam material in liquid form solidifies into a solid plastic foam material for packaging the article.
