The two adhesives used for flexible packaging in Henkel Loctite liofol RE 

series have obtained recyclass certification and are fully compatible with 

the existing recycling process of polyethylene (PE). 


The development of these adhesives ensures

Flexible packaging can be recycled into higher quality plastic,

And in a variety of applications to achieve a better secondary

Life choice. This is to achieve greater sustainability and create

A key milestone of circular economy.

Recyclass is a comprehensive cross industry initiative that promotes 

the recyclability of plastic packaging and ensures the traceability and 

transparency of recycled plastic content in Europe. 

The organization aims to establish a scientific foundation through 

rigorous scientific testing and certification of innovative materials

A unified calculation method of recycled components.


Senior manager of Henkel polyurethane product development

Guilherme Fernandes explained, "to get

Recyclass certified, our innovation is solvent-free

Adhesives have been widely used in accordance with strict scientific agreements

The test proves its suitability for the packaging recycling process

Usability. Henkel's solution has been

Test of recyclasspo thin film technical committee.

During the evaluation, different solvent-free solutions were reviewed

How does the adhesive affect the Recycled LDPE film layer

Performance. "

The results show that the two solventless composite adhesives are both

It can be compared with the existing polyethylene flexible material industry in Europe

The recycling process is fully compatible. In addition, these two methods are used

The adhesive will not have any impact on the quality of recycled materials
