 The packaging must not only look attractive but it must also protect the contents against the environment. Glass has an excellent gas and UV barrier, but does not block visible light. Carton is light-proof and reasonably gas-tight. Modern plastic bottles can be fabricated in several layers, which makes them impermeable to oxygen and at the same time block UV light without losing transparency.
Non-transparent plastic bottles, for example made of HDPE (high-density polyethylene), can be blowmoulded in a six-layer variant, which provides a very good barrier to both light and oxygen.
Stork supplies lines for every type of package and every form of preservation so according to your choice of process or package.
