337 is a quick drying, transparent stamping ink developed especially for polyethylene bags. Yellow and white are also available but they are pigmented.

We recommend using stamps with sponge-rubber base and guide rail for fixation for stamping on these particularly smooth plastic surfaces and for better legibility of the imprint. If such drying times are not required, use delaying agent 337.

We also recommend 337 for marking various types of plastic foil. Suitability tests should be carried out because too many different qualities are available to allow a reliable recommendation.

Drying time:
~2min (PE foil)


low viscosity, ~10-30sec
(Ford 4mm cup)

Stamp material:
Rubber or special photo polymers

Stamp pad material:
We recommend felt plate pads for 337. Office stamp pads are only suitable with reservations, because they dry out relatively quickly. On automatic stamping machines, systems with ink reservoir are preferable.
