A process treats the surface of a polymeric tampon applicator so as to improve its whitening. The process applies electron beam energy to the applicator in sufficient magnitude and time duration to achieve the desired whitening.

Process of improving the whitening of a polymeric tampon applicator

A tampon applicator has a barrel and a plunger telescopically mounted within the barrel. In a preferred embodiment, one or both of the barrel and plunger is made of a water dispersible material, and is exposed to a source of infrared radiation to minimize surface stickiness on initial contact with moisture. In an alternative embodiment, the barrel or plunger can be coated with a water dispersible material prior to exposure to infrared radiation.

Infrared treated tampon applicators

A tampon applicator having a barrel and a plunger telescopically mounted within the barrel. In a preferred embodiment, one or both of the barrel and plunger is made of a water dispersible material, preferably polyvinyl alcohol resin, and is exposed to infrared radiation to minimize surface stickiness on initial contact with moisture. In an alternative embodiment, the barrel or plunger can be coated with a polyvinyl alcohol coating prior to exposure to infrared radiation.
