Shrink Bands

What are Shrink Bands?

A band of PVC plastic that fits around the cap and neck, or sometimes the whole bottle or jar, which must be torn and removed to open the bottle. Once the band has been removed it is not possible to reapply the used band.

Shrink bands are easy to apply to your product

First select the correct size shrink band for your product. Then simply slide the shrink band over the product, leaving enough room at the top for the band to form to the cap, apply heat evenly with a heat gun or hair drier until the band has shrunk giving you tamper evident seal the snug fit you desire.

Thing to keep in mind when using shrink bands

Container Design: The most common problem with bands is improperly designed components. If the bottle or jar you wish to shrink band has a straight neck with no lip, the band can be removed intact. To get a properly fitting shrink band the container should have a lip for the band to cling to. A straight-sided cap can cause a similar problem if the band does not come up and over the top.

Improper Shrinkage: To properly seal your container using shrink bands you must apply the right amount of heat in the right place. Not enough heat will cause the shrink band to not securely seal the container. Applying too much heat will stress the shrink bands perforation causing it to break. If heat is not evenly applied it will result in an uneven application of the shrink band.
