| Summary: |
ACTIVE packaging, sometimes referred to as interactive or “smart†packaging,
is intended to sense internal or external environmental change and
to respond by changing its own properties or attributes and hence the internal
package environment. Active packaging has been considered a component of
the packaging discipline for several decades or since the first inclusion of desiccants
in dry product packages. In their own moisture-permeable sachets,
desiccants absorb water vapor from the contained product and from the package
headspace, and absorb any water vapor that enters by permeation or transmission
through the package structure. As separate entities within packages,
active packaging sachets, pouches, patches, coupons, labels, etc., are not often
integral to the package—a semantic differentiation.
