SMART PACKAGING : Internal Indicator 

Smart Packaging (or Intelligent Packaging) is used to described interactive devices solutions that can indicate/notify to the consumer information about the functions and the properties of the packaged product and if it’s impaired.

These type of devices can be divided in three groups:

- The external indicators which are attached outside the package and generally include time-temperature and physical shock indicators.
- The internal indicators which are placed inside the package or attached to the lid, which indicate oxygen leak , carbon dioxide and microbial presence.
- The information indicators which interact with the consumer and provide
information of the product (ingredients and expiry date) and of its usage;product traceability, anti-counterfeiting and tamperproof can also be included in this category.

Here is published a very interesting Internal label indicator which shows the shelf-life of a pear!
