摘要：
In a wound paperboard tube, adhesive is applied between two or more structural paperboard layers in a partial-coverage pattern characterized by spaced regions of adhesive interspersed with adhesive-free portions of the facing surfaces of the layers. The pattern can comprise islands of adhesive spaced apart in both circumferential and longitudinal directions of the tube, or intersecting lines of adhesive spaced apart in both circumferential and longitudinal directions and forming a grid, or the like. The tubes can be spirally wound, convolutely wound, or formed by a linear draw process. Tube strength is not substantially compromised by reducing adhesive coverage substantially below 100%, on a surface area basis.
