Tamper Evident Perforated Shrink Bands
These are clear PVC plastic bands that fit around the opening of a jar, bottle or sometimes wrapping around the entire product. There is perforation on the band to easily tear and remove the band from the product. Once the band is removed, it cannot be reapplied. Therefore it is often used as a tamper-proof packaging.
To find the size of the bands that will work for your cosmetic jars and beauty containers, measure the diameter of the widest part of the area that the shrink band is going to be placed and that will be the width of the band required.
To install the Tamper Evident Perforated Shrink Bands, simply slide the band over the area of the container that needs to be secured, apply heat with a hair dryer or heat gun. The bands will shrink to fit onto container rather quickly.
