1. An ostomy base plate comprising:
a film adapted to elongate in a range from 250% to 700%;
an adhesive composition deposited on a proximal surface of the film, with the adhesive composition adapted to adhere to skin around a stoma;
a hole formed through the film and the adhesive composition, where the hole is adapted for placement around the stoma; and
a reinforcement ring connected to a distal surface of the film;
wherein the ostomy base plate comprises a first section surrounded by a second section, with the first section extending in a radial direction between the hole and the second section, and the second section extending in the radial direction from the first section to an outer boundary of the ostomy base plate;
wherein the film in the first section of the ostomy base plate comprises undulations formed in the film and into the adhesive composition to provide the adhesive composition in the first section of the ostomy base plate with valleys of relatively lower adhesive thickness and ridges of relatively higher adhesive thickness.
