A method of making a customized packaging film for a pharmaceutical product is disclosed. Cladding an Sn or Sn alloy coating with a prescribed metal continuously or discontinuously in such a way as to make the coating partially exposed inhibits the generation of whiskers by contact pressure in pressure welding, and further inhibits the generation of whiskers without impairing the solder wettability of the coating even when the cladding is not followed by heat treatment or reflowing. In another embodiment, an apparatus is characterized by an intubation-tube placement device; and at least one tactile-accentuator flap coupled to the intubation-tube placement device.
