Mono-material for Sustainable Packaging

Sustainable thinking and action have long been part of everyday life and environmental and climate protection are now essential components in company policies. In the packaging sector, too, legislators have now formulated stricter guidelines and critical consumers are increasingly paying attention to environmentally friendly packaging. Here, Wipf AG offers innovative products with a wide range of flexible sustainable packaging solutions for (almost) every need.

Why mono-materials

The advantages of packaging made of monomaterials are obvious: it consists of several layers of a single material. They are recyclable and save resources. Their applications are just as versatile as those of conventional packaging.

Sustainable packaging from Wipf is light and flexible in use. They offer optimum protection against moisture, oxygen and external contamination - and are robust enough for transport and in use.

Mono-material pouches offer many possibilities

With currently 12 different pouches made of mono-material laminates or PCR material, Wipf offers optimum sustainable packaging solutions for both wet and dry contents. Wipf has even developed a suitable solution for retort applications. The product range of monomaterials includes stand-up pouches and flat pouches with and without spout, with and without window, with and without zipper.

Some highlights

  • Highly recyclable laminate
  • Possible with and without spout
  • Good drop test resistance 

The PP stand-up pouch can be used up to hotfill.

Retortable mono PP pouch

  • Material: OPP/OPPsx/CPP
  • Material thickness: 20/20/60 µm
  • With very high oxygen barrier

  • Ideally suited for convenience products such as vegetables, rice dishes, soups, chestnuts, etc.

PE stand-up pouch with/without zipper

  • Material: HDPEsx/PE
  • Material thickness: 32/100 µm or 20/16/75 µm
  • With/without window and high oxygen barrier

 The PE stand-up pouch with zipper is resealable.

PP stand-up pouch with zipper

  • Material thickness: 20/16/75 µm
  • Reclosable
  • With window

Ultrasonic spout sealing system for optimum processing

The sealing of the spouts is a critical area, especially with mono-materials. That is why Wipf uses an alternative sealing process here. For this purpose, the machine park has been expanded with a new ultrasonic spout sealing machine. The sealing line also offers the possibility of supplying spout bags directly mounted on rails. Depending on the pouch format, the rails can be loaded with up to 45 bags and fed directly to the filling line at the end customer in one step. Efficient and time-saving, because the tedious and time-consuming insertion of individual pouches is no longer necessary. The only condition: The customer must have an appropriate filling machine.

And last but not least: Sustainable valves

With its WICOVALVE® W606E and W616E bio compostable valves for coffee packaging, Wipf comprehensively rounds off its sustainable product range. The two compostable valves are based on the well-known and proven W606 and W616 coffee valves and can be thermally sealed just like them. Perfect for combination with biodegradable laminate materials. All WICOVALVE® valve types are also available in recyclable PP and PE. This offers coffee roasters a completely sustainable packaging with optimal aroma protection for whole beans as well as ground coffee. Good for coffee - and the environment.
