Heat Shrink Tamper Bands
As a manufacturer using shrink tamper bands, you have the pain of actually applying shrink tamper bands. Machinery can be fickle; hand applying can be time consuming. It involves heat and it is, in general, quite a difficult process to implement and can be costly with materials.
On the consumer side of things, removing a shrink tamper band is quite a frustrating task for many who find it very difficult to see where to peel or where a perforation mark is on a clear tamper band. Both younger and older consumers can find it difficult to open a product with a tamper band that has been shrunk on.
The heat shrink tamper band also can lead to a lot of dust being attracted to the product on the tamper band for reasons of static and also because the heat shrink tamper band produces a lot of edges where dust can collect and get under.
User Friendly Tamper Evidence Options
There are two relatively easy processes to implement in your production that can put tamper evidence on your product and also might get a much more user-friendly experience to open the product.
Induction sealing allows for you to put a foil across the top of your container, providing both tamper evidence and also a much better barrier property than a shrink tamper band. In most cases, you don’t need to deal with the induction sealing material; it’s already in the cap when you purchase it for your product.
Alternatively, you’ll be buying the induction sealing material in roll form, to apply with a cap less induction sealing machine or in pre-cut in smaller volumes to deal with cap less induction sealing.
Pressure Sensitive Labels
The other method is simply using a pressure-sensitive label with a little finger that might go over the cap or a small round or rectangular label that simply folds from the opening across and down the product. For example, a lot of pharmaceutical boxes will have a small, round and often transparent label that goes over the edge and onto the flap of the box that would open.
Jams and spreads often have a label that go either from above on the cap and right down the side of the container or they have a label that has, from the body of the label, on the round part of the product, it has a finger that extends and touches or goes over the top of the cap. In the case of labeling, the label has to be broken, typically, before the product can be opened; and that’s a form of tamper evidence.
Labeling equipment doesn’t require heat and the labels are easy to source and it’s much easier to order to automate or to semi automate than the heat shrink tamper band.
In summary, you’ve got two options to get rid of the heat shrink tamper band which is both a problem in production and a problem for the consumer: Method 1, Induction Sealing and Method two, tamper evident labels. Other options exist but these are by far the two most predominant and widely used options.
