What is the difference between a tamper-evident seal and a child-resistant closure?
- Shrink bands: This type of seal is used on products such as mouthwashes. Shrink bands are PVC or plastic sleeves that cinch tightly around a container's lid and neck. They are heated, which causes them to contract and fit the package perfectly. The shrink band will break or show obvious damage if someone tries to open the product before buying it, which is a sign of tampering.
