Start in the middle, work outward, and choose a size the curve can take. A flat sticker wraps easily around a surface that curves in one direction, like the side of a can or a bottle, because it only has to bend. A surface that curves two ways at once, like a helmet, a ball, or the shoulder of a bottle, makes it bend and stretch at the same time, and that's when edges wrinkle and lift.
Size it to the curve
- Cylinders (bottles, cans, tubes, and straight tumblers): the sticker bends side to side and stays flat top to bottom, so taller-than-wide shapes sit best. The tighter the curve, the smaller the sticker should be.
- Tapered tumblers and cups: the curve changes from top to bottom, so a wide sticker can't lie flat along its top and bottom edges at once. Keep it narrow.
- Domes and compound curves (helmets, hard hats, and the shoulders and bases of bottles): keep stickers small, and put them on the flattest area you can find.
Choose a shape that helps
Sharp corners are where lifting starts. Circle Stickers and Oval Stickers have no corners at all, Rounded Corner Stickers have corners with a 0.1" radius, and a Custom shape follows the outline of your artwork. Any of them holds a curve better than a square-cornered rectangle. See which sticker shape to choose.
Putting it on
- Clean the spot with isopropyl alcohol and let it dry.
- Peel the backing and touch the center of the sticker down first.
- Smooth outward from the center along the curve, one side and then the other.
- Press the edges down firmly, last of all.
- Leave it 24 hours before it gets wet.
If an edge starts to crease, lift it gently straight away and lay it down again, easing it into the curve. A few seconds of a hair dryer on low makes the vinyl easier to shape. If it still won't lie down, the sticker is too big for that curve.
Labels on bottles and jars
For product labels, measure the part of the container that's truly flat or a straight cylinder, and keep the label inside it. See sizing a wine label to the bottle and labels for tins, tubes, and tight curves.
BOPP, our plastic roll-label film, is fairly stiff. That's right for rigid bottles and jars, but on soft squeeze bottles it can wrinkle; see why labels wrinkle on squeeze bottles.
