Our adhesive range includes a range of water based hybrid, synthetic and starch based labelling and paperbag, flat and satchel, glued windows, production adhesives.
This specific glue is used as Long seam glue for paraffin bags on a Holweg paperbag production machine.
It concerns food packaging (BRC)
Adhesive Application equipment: spraying system
Substrates: paraffin paper; no substrates available.
RESEARCH requirements.
Testing is done on paraffin paper, which is relatively easy to glue and adhere. Also tests on heavily paraffinized paper are made.
COMMENTS AND CONCLUSION
Proposal: 1) K3508
2) K1146 if the best adhesion is to be obtained,
Note: AA 612 is a strong sticky adhesive; it will be more difficult to clean and process than K 3508
Both are suitable and allowed by European and US regulations for bonding food packaging.
