ABSTRACT:
A photographic album page comprising a fibrous centrally disposed lamina and a pair of overlying clear synthetic resinous laminae. Pockets are formed by ultrasonic sealing of the clear laminae together through the fibrous lamina which disintegrates under the generated heat of sealing. The pockets are thus formed as a continuous sealing operation at the same time the page is laminated by sealing in broken lines, whereby the fibrous lamina retains its structural integrity.
