An apparatus for forming a weld between first and second thermoplastic materials in which the softening temperature of the second thermoplastic material is lower than that of the first thermoplastic material. The apparatus includes a supplier for supplying the first thermoplastic material and the second thermoplastic material to the same weld position with the second thermoplastic material at a first side of the first thermoplastic material, and a projector for projecting a laser beam to the weld position from a second side of the first thermoplastic material.

A double zipper pouch having first and second pockets adjacent one another and with a common wall portion, each pocket having an opening for receiving contents such as identification papers. The first and second pockets are formed so that their openings are displaced relative to one another. Pressure actuated resealable fasteners are disposed adjacent the openings in each of the first and second pockets. First and second indicators are also disposed adjacent the openings to provide an indication of the location of the associated opening. The indicators are preferably different from one another so as to provide an identification for the associated pocket. An adhesive material is formed on the back of the first pocket for affixing the pouch to, for example, a package.
