ABSTRACT:
A plastic, pouch-type package with a recloseable, zipper-like closure and the method of making it in which the mass of the plastic closure is reduced at opposite side edges of the pouch by forming holes passing through the interlocking tongue and groove portions so that the subsequent application of heat and pressure along parting lines at the side edges of the pouch accomplishes fusion and sealing of the closure to the pouch with less time and heat than would otherwise be required.
