If you’ve ever supplied medical-grade colostomy film to healthcare facilities or worked directly with ostomates, you know that this humble, often overlooked product is far more critical than its name suggests. As a colostomy film provider, I’ve spent countless hours answering questions from nurses, home health aides, and people living with ostomies who want to understand not just how to use our film, but how to use it safely. The truth is, when it comes to something as thin, flexible, and essential as colostomy film, safety isn’t just a regulatory box to check—it’s the difference between a comfortable day out and a painful, infection-prone complication. In this post, I’m breaking down the key safety precautions we emphasize with every order, the common mistakes we see people make, and why partnering with a reliable supplier matters more than you might think. Colostomy Film
First, let’s clarify what colostomy film is, because there’s a lot of confusion out there. It’s not the same as the plastic wrap you use for leftovers, and it’s not a bandage. Medical-grade colostomy film is a thin, hypoallergenic, polyurethane-based film designed to protect the peristomal skin—the skin surrounding a stoma—from output, adhesive residue, and friction from ostomy bags or accessories. For people with ostomies, peristomal skin complications (PSCs) are the most common issue they face; studies show up to 70% of ostomates develop a PSC at some point, and many of those cases could be prevented with proper film use, stored incorrectly, or applied poorly. That’s where safety precautions start: with understanding that this product isn’t a one-size-fits-all solution, and that even small missteps can lead to big problems.
One of the most basic, and most often skipped, safety rules for colostomy film is checking the integrity of the packaging before use. I can’t tell you how many times a customer has called us saying their new roll of film had a tear, a crease, or a broken seal—problems that render the film unsafe for use, even if the expiration date isn’t until next year. Polyurethane is a delicate material; if the packaging is compromised, the film can absorb bacteria, dust, or other contaminants that can cause skin irritation or infection when applied. We always remind our clients to inspect every roll before opening it, and to discard any that show signs of damage. For healthcare facilities, this means checking stock regularly, because films stored on a back shelf for six months might have packaging tears you don’t notice at first glance. For individual ostomates at home, this means keeping your film in a cool, dry place—never in a bathroom medicine cabinet, where humidity can break down the seal faster and increase the risk of contamination.
Next, proper application technique is non-negotiable for safety. Even if you have a high-quality film from a reputable supplier, if you apply it wrong, it won’t do its job—and could even cause harm. The first step before applying colostomy film is preparing the peristomal skin. This is a step many people rush, but it’s critical: skin must be completely dry and free of residue from old adhesives, stoma pastes, or wipes that contain alcohol or fragrances. Alcohol-based wipes, for example, can leave the skin feeling sticky long after they dry, which prevents the film from adhering properly. If the film doesn’t stick, it can lift when the ostomy bag is changed, leaving the skin exposed to output. We’ve seen cases where ostomates tried to reapply film that didn’t stick, pressing it down with dirty hands or using adhesive spray to “boost” hold—both of which introduce bacteria to the area. The correct method is to gently clean the skin with a pH-neutral, non-irritating cleanser, pat it completely dry with a soft, lint-free cloth (never rub, which causes friction), and wait 30 seconds to a minute to make sure all moisture is gone.
When it comes to cutting the film to size, another common mistake is cutting it too small or too close to the stoma. The rule of thumb here is to leave a 1/8 to 1/4 inch gap between the edge of the film and the stoma. If you cut it too close, the output from the stoma can leak under the film, leading to skin breakdown. If you cut it too large, the excess film can bunch up, catch on clothing, or create folds that trap moisture. I always tell people to trace the stoma on a piece of paper first, then cut the film slightly larger than that traced shape—this gives them a clear guide without guessing. Also, never stretch the film while applying it. Stretching polyurethane film too tight can cause it to become brittle over time, crack, or pull away from the skin prematurely, which is a safety risk because it leaves gaps for leakage. Take your time when smoothing it down: start from the center, press outward toward the edges, and make sure there are no air bubbles or wrinkles under the film. Air bubbles can create pockets of moisture that lead to irritation, especially if they’re near the stoma.
Storage after application is another area where safety precautions are often overlooked. Colostomy film is designed to be breathable, but it’s not indestructible. Once applied, it needs to be treated like any medical device against friction and moisture. I always advise people to avoid tight clothing or belts that rub against the film area. Friction is one of the top causes of film lifting and skin irritation—even a well-applied film can peel if it’s constantly rubbing against a waistband. For people who are active, like athletes or people who work manual labor, we recommend choosing a thicker, more durable film variant (if supplied by a reputable brand) or adding a thin layer of skin barrier paste around the edges to reinforce adhesion. Also, if you’re bathing or swimming, make sure the film is fully waterproof (not all films are) and avoid hot tubs or very warm baths for long periods—high temperatures can weaken the adhesive layer, causing the film to fail.
Now, let’s talk about a specific safety precaution that’s unique to using colostomy film around a stoma: watching for signs of adverse reaction. Even with all the right steps, some people have allergies or sensitivities to the materials in the film. Our films are hypoallergenic, but no product is 100% safe for everyone. Common signs of a bad reaction include redness, itching, blistering, or a rash under or around the film within 24 to 48 hours of application. If you notice any of these, stop using the film immediately, gently clean the area, and consult your ostomy care nurse. As a supplier, we work closely with our clients to provide alternative products if a patient has a known sensitivity to polyurethane, like a hypoallergenic silicone-based film option. What’s important here is that people don’t ignore these signs—many think the redness is just normal irritation from having a stoma, but it could be a sign that the film is causing harm, and switching to a different product can fix the issue.
Another critical safety point is not reusing colostomy film. I know it’s tempting, especially for people who have limited budgets, but film is a single-use product for a reason. Once you remove a piece of film, it’s stretched, exposed to bacteria from the skin and surrounding environment, and its adhesive properties are compromised. Reusing it means putting yourself at risk for infection, because you’re applying a product that’s already been in contact with your skin and has lost its protective properties. As a supplier, we offer bulk pricing for healthcare facilities and home care providers to help make our films accessible, so people don’t feel the need to reuse them to save money. We also emphasize that the cost of a roll of film is far less than the cost of treating a skin infection or peristomal breakdown, which can require doctor visits, prescriptions, and extended recovery time.
Now, I want to address a concern I hear all the time from people who are new to ostomies: is it okay to use colostomy film every day? The short answer is yes, but with a few precautions. Changing the film too often can irritate the skin, because every time you peel it off, you’re pulling at the delicate peristomal area. Most ostomates change their film every 3 to 5 days, or whenever the ostomy bag is changed, depending on their output. That said, if you have a high-output stoma (like an ileostomy), you may need to change the film more frequently, and it’s important to work with your care team to find a schedule that works for you. Another point: don’t use lotions, creams, or powders on the area under the film, because these products can create a barrier that prevents the film from adhering properly. If you need to moisturize the skin around the stoma, wait at least 24 hours after removing the film, and make sure all residue is completely gone before applying new film.
