Application and use
The pressure-sensitive adhesive 72Bpt is specially developed for applications where the labelled packaging material, paper or board, is recycled after use. It is not necessary to separate the label for this, as the adhesive 72Bpt does not have negative effects on the recycling path for paper packaging materials. The recycled paper or packaging material can be reused and printed on without any problems. In relation to the total packaging material, the weight share of the label can be up to 25%.
The adhesive 72Bpt has a very high initial tack and is therefore also suitable for fast-running dispensing systems in which the initial tack has to be built up extremely quickly (e.g. blow-on process).
Certificate on the evaluation of recyclability within the paper industry
The pressure sensitive adhesive 72Bpt has been certified as "Recyclable" by the Papertechnische Stiftung (PTS) following the PTS method PTS-RH 021:2012 (Draft Oct 2019). The certificate is valid in combination with the following material:
240 (HERMAweiß super) / 72Bpt
242 (HERMA extracoat) / 72Bpt
Processing
