Remove a Wrinkle From a Vinyl Banner
The more “plasticizers” that are used in the manufacturing process of a vinyl banner, the softer and more supple it will be. However, we always suggest to never fold their banners, because they will wrinkle, and the wrinkles may or may not be removable. Always roll your banners, and preferably on a hard cardboard or plastic tube core so that it won’t be crushed or folded.
These types of displays are made using a loosely woven nylon fabric, which is encased in hot PVC vinyl. Once it cools, it is trimmed and rolled onto larger rolls, typically 50 yard or meter rolls, and shipped to distributors world wide. You’ll note that the vinyl banner material is not folded, but rolled, because vinyl banner material was not made to be folded.
However, if enough heat is applied, it is possible to reduce or possibly even eliminate wrinkles, dependent on how deep or heavy the wrinkle is. This a bit of a sticky wicket because too much heat will actually melt the PVC material, but not enough won’t remove the wrinkle.
My best advice is to go slowly, although you need a heat gun to get the heat you need to actually remove the wrinkle, so going slowly may be a bit tricky. I suggest “waving” the heat gun back and forth fairly rapidly to soften the material, but don’t linger on any spot for any length of time or you may just burn a hole in your banner.
This method will often reduce and possibly even remove wrinkles from a vinyl banner, although there is a possibility that there may still be a small mark left where the corner of a fold was. This is the toughest place to remove a wrinkle, and in fact, it is possible here that you won’t remove the wrinkle completely, though you may mute it somewhat.
What you need to remember with vinyl banners is that they’re an imperfect medium for signage, so you’re not going to get as perfect of a look as you would with, say, a dye sublimate printed knit polyester cloth fabric banner, which can be stuffed into a suitcase and the wrinkles will usually hang out within a couple of hours, if there are any at all.
Vinyl banners are normally outdoor banners as well, an as such, they are not subject to the scrutiny that other interior signs or banners might be subject to. We often apply the 35MPH rule, which states that at 35MPH (the speed of someone driving by your banner) and 100 feet away, no one will ever see that wrinkle!
So, in my opinion, a vinyl banner should be purchased to be hung up one time. It will come rolled up (unless it’s a billboard cover) and should be unrolled and hung up in a permanent location. That way it never has a chance to be folded up. Again, as stated a couple paragraphs back, if you have a banner or need a banner to take with you to a show or a presentation, polyester knit fabrics will look better every time.
