Since my surgery 2 years ago, I use the Hollister 2-piece system: 11204 wafer, 18194 bag. I also use a Coloplast Brava moldable ring under the wafer.
I haven't noticed any change in the wafer. But I have a colostomy, so my sealing and wearability requirements differ from those of an ileostomy. I now go 12 to 14 days between wafer changes. My skin looks good, and hair growth is manageable.
I have boxes of wafers from 2 years ago. I'm a machinist and have precision measuring tools. I'll measure a wafer from November 2022 and compare it to one I received in February of this year.
Manufacturing a product while maintaining acceptable quality is an ongoing challenge, especially with supply chain variability. Availability of basic materials, delivery time, and costs can vary significantly.
Companies do have to maintain profits... or they disappear.
Petroleum is the base for most plastics. As drilling and refining decline due to environmental concerns, the cost of plastic base materials will rise, affecting manufacturers in multiple ways. Even down to the cost of diesel for trucks to ship plastic stock to the factory, then later deliver the finished product to medical suppliers.
A lawsuit was recently filed against a manufacturer of Ziploc plastic bags, claiming the product is harmful and lacks proper warning to consumers. Ziploc bags are made from thin plastic like ostomy pouches.
Ostomy pouches are made from high-grade polyethylene or polyurethane. Ziploc bags are made from polyethylene. A lower grade of polyethylene plastic, I'm sure... but still... plastic. The class action lawsuit is about undisclosed microplastics in Ziploc bags that may shed during freezing or heating.
Imagine a world without plastic.
