The tamper evident packaging will vary depending on whether the product will be handled by pharmacists, customers or both parties. The FDA calls for one layer of tamper evidence for products that are solely behind the counter with pharmacists, and two layers must be used for over the counter products.
In the pharmaceutical industry tamper evident seals are mandatory for certain applications and are now standard for thousands of branded and generic pharmaceuticals. They're considered for others such as pain relievers, cold medicines, nasal sprays and eye solutions, as an added value for the consumer.
Some features of tamper evident packaging for the pharmaceutical industry include film wrappers, blister and bubble packs, heat shrink bands/wrappers, bottle mouth seals and breakable caps.
