Biaxially oriented polypropylene (BOPP) specialist Treofan has developed a new film known as Treofan EPT for in-mould labelling in deep drawing or thermoforming.
The new film with a special surface that attaches perfectly to deep-drawn films, enabling stable fusing of thermoforming and label film at low temperatures and pressures, while delivering look and feel as good as injection-moulded products, the company said.
This addresses the challenge of attaching BOPP labels to thermoformed products, which required a separate process step until now.
The fusion between container and label cannot be differentiated visually and functionally from the complete fusion achieved by injection molding.
The new Treofan EPT has undergone several tests, including with Illig, a provider of machinery and tools for thermoforming and packaging technology.
It is being launched to the market on a large scale.
With 1,100 people, Treofan operates four production sites in Germany, Italy and Mexico, where it manufactures BOPP films.
The company offers its products under the brand names Treofan and TreoPore. Its products include solutions for the packaging and tobacco industries, labels, and technical films for electronic applications such as batteries and capacitors.
