Card forming packaging is defined as to fuse blister on the surface
of card with vacuum forming oil. We usually see it used in
supermarket’s battery package. It requires sealing equipment to
seal the product between paper card and blister. Problems to be noted: Card surface must be applied with vacuum forming oil (so as to bond
with PVC blister) The product to be sealed shall not be too heavy, for blister is
just stuck to the paper card.
