Abstract
Abstract A method and apparatus for inexpensively but effectively packaging electrostatic sensitive products by sandwiching the product between opposing plies of an electrostatic discharge protective film while at the same time securing the edges of the plies between two opposing parts of a package so that the product is suspended by the plies within the package. A stretchable, heat shrinkable, static discharge protective film surrounds and encloses each of the opposing package parts in order to provide the suspending plies to suspend the product.
