Choosing the right film

There is much to consider when choosing the right packaging film for wool insulation. For example, what type of wool insulation material is being packaged – glass wool, stone wool, slag or loose wool? And in what form will it be packaged – rolls, slabs, loose material or as a specific technical product?

In addition, when selecting the right packaging film, you need to consider the degree of compression and the type and density of the insulation material.

Increased compression force

The compression force in wool insulation has increased dramatically in recent years so that logistics efficiency can be achieved. The performance of our wool insulation packaging film has advanced to match this.

Excellent film weldability and film strength are essential to maintain packaging compression. We therefore work in close cooperation with machine suppliers and integrators, as well as customers, to meet new packaging film technical standards.

We can offer additional MDO processing to produce stiff and strong films with reduced thickness suitable for wool insulation multipacks. The MDO process reduces the amount of packaging film needed.

Sustainable packaging

Through our ongoing product development, we have taken several measures to ensure our films and production processes are sustainable. Our films are now thinner and stronger, while maintaining all their required technical properties. We continue to increase the amount of renewable and recycled raw material used in our films where ever it is technically possible and is of benefit to the customer. We continuously optimise our printing process to make it more efficient, safer, and greener. Our aim is to help our customers find the best solutions to meet their sustainable packaging challenges.
