Abstract

A product-to card or card type package is provided having a preapplied heat shrinkable plastic film for securing a product thereto. More particularly, a package is provided having a main panel and a pair of side support panels which are hingedly connected to the opposed side edges of the main panel. A heat shrinkable film extends between the side support panels and is adhesively connected thereto such that after a product is inserted between the plastic film and the main panel, and thereafter the package is subjected to heat, the plastic film will shrink into close conformity with the product thereby causing the side support panels to be drawn into abutting relationship with the product such that the product is secured to the package. An aperture may be provided in the main panel for receiving a portion of the product so as to aid in preventing longitudinal shifting of the product in the package.

A composite blank for forming a package having a preapplied heat shrinkable plastic film for securing a product thereto comprising:

a sheet having first and second sides defining a main panel and a pair of side support panels hingedly connected by means of fold lines to the opposed edges of said main panel;
and
a heat shrinkable plastic film substantially coextensive with said sheet and extending between said side support panels on a first side of said sheet and adhesively connected thereto on said first side, whereby when a product is inserted in said blank between said plastic film and said main panel portion of said first side of said sheet, and thereafter said blank is subjected to heat, said plastic film will shrink into close conformity with said product thereby causing said side support panels to be drawn inwardly into abutting relationship with said product by said shrinking plastic such that the product is secured to said main panel, said side panels and said shrinking plastic.
