All about Full PP Pouches with high Barrier Properties
Barrier films are established firmly in our modern world for protecting foodstuff and other goods. Their possibility of being specifically tailored to the use is unmatched by paper, glass or metal. Further their low weight contributes to lowest energy consumption during transportation and makes them eco-friendly compared to the other packaging solutions. However the sustainability of plastics in general is still a big point of criticism.
Amongst missing waste management systems, many of today’s barrier film compositions are not suitable for being recycled for a second life in packaging. Typically their multilayer structure consists of several inseparable raw materials and hence cannot easily be processed to regrind, which may be used within a subsequent lifecycle. This has to be changed and we as leading supplier for cast film machines are happy to provide support to improve packaging solutions towards more sustainability.
With the FILMEX II cast line film structures can be processed flexibly. At the same time they can be designed to comply with the need for maximum recyclability. The pouch made of a full PP laminate with high barrier properties is a design example for a sustainable packaging application. A base film structure mainly containing polypropylene with a minimized usage of high barrier raw materials ensures that design requirements for recyclability are met. An additional inorganic coating on the base film provides additional enhancement of the barrier properties without adding noteworthy amounts of extraneous material. By that oxygen transmission rates (OTR, 23°C/50% RH) below 1 may be achieved. Finally the barrier film was laminated with a counter printed PP based film to consequently follow the idea of using only one material for better sustainability.
- Barrier properties adjustable by incorporation of high barrier resins, as well as by applying thin inorganic coatings
- Excellent optical and mechanical properties delivered by a highly efficient cast film process
- Most consistent film quality with superb layer distribution for thinnest barrier layers
