Abstract
A profile sealing strip for providing a resealable closure includes a lateral flange, a sealant layer, and a closure portion. The lateral flange has a first and second section each having a length, an outer surface, and an inner surface. A plurality of ribs extends along the length of the outer surfaces wherein adjacent ones of the ribs form a channel therebetween. The closure portion includes a closure means and a base. The base of the closure portion is disposed between and connected to the first and second sections of said lateral flange. The closure means protrudes beyond the inner surfaces of the first and second sections of the lateral flange. The sealant layer has a first portion and a second portion. The first portion of the sealant layer is adjacent the first section of the lateral flange and connected to outer segments of the ribs. The second portion of the sealant layer is adjacent the second section of the lateral flange and connected to outer segments of the ribs. Corresponding mating profile sealing strips are then attached to a package by a heat-sealing process which provides the package with a reclosable seal.
