Abstract
A method of making a reclosable product package (64, 100, 142), a package-making apparatus (10) for the method and the reclosable product package (64, 100, 142) in which block cheese or another product (45) which does not slide well during packaging in placed on a continuous length of thermoplastic packaging film (12). Various folding directions (44, 62, 90, 106, 114) of the packaging film (12) and various placement of reclosable zippers (73, 108, 119) produce various reclosable product packages (64, 100, 142) with various peel seal (40, 41, 87, 88) arrangements.
