One very promising approach is to develop pack concepts based on materials, for which closed recycling loops already exist. One example of this are paper fibre-based packaging solutions, since the paper fibre can be fed back into the existing recycling loop, after it has been used. Even if the material is disposed of in the normal packaging waste rather than in the recycling bin, it can be detected in today's modern recycling centers, where it is removed and fed into the proper recycling loop.
MULTIVAC's PaperBoard offers a range of solutions for producing packs made from paper fibre-based materials. The packaging materials, which were developed in conjunction with leading manufacturers, can be run on standard machines and meet the requirements of the food industry as regards barrier properties and protective functions. The PaperBoard range includes solutions for producing MAP or skin packs on thermoforming packaging machines and traysealers. Both types of packaging machine can be individually designed to meet the particular output requirements of customers.
When it comes to traysealers, it is possible to run either trays or pre-cut sheets made of board or cardboard composites, which can be separated by the consumer after use into their constituent parts. MULTIVAC offers three different solutions for producing paper fibre-based packs on thermoforming packaging machines. Where vacuum skin packs are produced, formable paper composites can be used, which are available in various grammages and with different functional layers. Cardboard composites from the roll can also be used as carrier materials for vacuum skin packs. Both types of carrier material can be separated by the consumer after use into their constituent parts.
In addition to this, we have also developed a machine concept for running cardboard trays made of mono board on thermoforming packaging machines. A suitable plastic sealing layer is applied in the forming die, which enables the appropriate skin film to be sealed. This concept also enables the consumer to separate the packaging materials into their constituent parts.
