Shrink Bands
Shrink bands and shrink wrap are the final touch to your products that tell people that you are a professional. They show that you are concerned that the product they buy, that it is as fresh as when you made it.
Shrink bands not only protect your customer, but they also help to keep your product in a sellable condition. They are a instant indication to whether a container has been opened or not.
A heat gun is all you need to shrink these bands around your jars.
