Why do labels wrinkle on squeeze bottles?

Because the bottle flexes and the label can't. BOPP is a fairly stiff film, so on a soft squeeze bottle it can wrinkle or lift where the wall bends. A smaller label on the stiffest part, rounded corners, and labeling full bottles all help. Test before a big run.

The bottle bends and the label doesn't. Squeeze bottles are made of soft plastic so they flex every time they're used. BOPP, the plastic film we print roll labels on, is one of the stiffer label films, and a laminate on top makes it stiffer still. Each squeeze bends the wall under the label, the label resists, and over time it creases, wrinkles, or lifts at the edges.

On a rigid bottle or jar, that stiffness is what you want: the label holds its shape and lies smooth. It works against you only on soft, squeezable containers.

What we offer

For squeezable bottles and tubes, the label industry uses softer films made to flex with the container. Our roll labels come in BOPP and paper. A squeezable film isn't on the order form, but we may be able to help, so ask us. Paper is no better here: it creases for good, and it doesn't handle the moisture these bottles usually see. With BOPP, the job is to give the label the best chance, and to test it on your bottle before a full run.

What helps

  • Put the label on the stiffest part. Most squeeze bottles have areas that flex less, often near the shoulder or the base. The panel people squeeze is the worst place for it.
  • Keep it smaller. A label that covers less of the flexing wall has less to fight.
  • Round the corners. Square corners lift first, so choose Rounded Corner Roll Labels, Circle Roll Labels, or Oval Roll Labels.
  • Label full, capped bottles. A filled bottle holds its shape, so the label goes onto the wall as it normally sits, and the wall doesn't dent as you press.
  • Press it down firmly, and let it set for a day before bottles are packed tight or squeezed hard.

Check the plastic too

Squeeze bottles are usually polyethylene (recycling number 2 or 4), one of the plastics adhesive finds hardest to grip. So a label on a squeeze bottle is fighting the flex and the surface at once. Clean the bottles with isopropyl alcohol before labeling. See why stickers don't stick to some plastics.

Test before a full run

Label a handful of real bottles and use them the way your customers will for a week or two. Squeeze them, get them wet, and leave one wherever the product will live, whether that's a hot car or a cold fridge. If the labels hold, you're set. If they don't, a smaller label or a firmer bottle is usually the fix. Tell us about your bottle before you order, and we'll talk it through.
