Methods of increasing the loft of a multi-ply thermoplastic film include stretching thermoplastic films with different rebound ratios, non-continuously laminating the films together, and releasing the films to create puckers in one or more of the films. The puckers can comprise billowing of one of the films. The non-continuous laminated areas can maintain the puckers in the films. The puckers can increase the loft of the film, improve the feel of the film, and/or modify the look of the film. The loft of such multi-ply puckered thermoplastics films vary independent of the basis weight of the films. Thus, multi-ply puckered thermoplastics films with increased loft of one or more implementations can look and feel thicker while using reduced amounts of thermoplastic material.
