As soon as the first PP tapes have been introduced in the market, ICHEMCO started to develop new dedicated systems for the printing of all sort of carton sealing tapes based on the BOPP technology.
Working in close cooperation with SIAT, primary manufacturer of PSA tapes printing machines, our goal has always been, and still is, to have a solution ready for all needs.
As a result of this research, we developed the following list of products:
The list of available inks, with prices, is available here.
For a correct choice of the printing system, variables to evaluate are:
This document will cover the printing systems presently available.
Tapes: All PP (PE, PET) tapes made with solvent, hot-melt, water adhesives, with or without release coats, corona treated or untreated.
Printing machines: SIAT L 36, SIAT L 36 C
Products | Packaging | Quantity to apply |
---|---|---|
PRIMER EPX-2 / EPX-2 ECO | Packed in 20 kg drumns | 3-4 g/m2 wet |
COLOR INK PP NITRO* | Packed in 10 - 20 kg drums | Depending on printing necessity |
RELEASE PP 25 DIL / PP 25 DIL ECO | Packed in 20 kg drums | 3-4 g/m2 wet |
* To be preferred to PAM inks because of the faster drying and of not being soluble in the toluene contained in most release agents
Tapes: BOPP with waterborne acrylic adhesive, either low-noise or normal
Printing machines: SIAT L 36 C, SIAT L 33/200, SIAT L 44
Products | Packaging | Quantity to apply |
---|---|---|
CORONA TREATMENT | 38 – 40 Dynes/cm | |
COLOR INK PP PAM+ADD.* | Packed in 10 – 20 kg drums | Depending on printing necessity |
* Normal PAM inks (COLOR INK PP PAMC) can also be used by adding our ADDITIVE ST2 (50% ink, 50% additive). When normal PAM inks are used without Additive, protecting the surface with a release coat (our RELEASE PP 25 DIL or RELEASE K100 D) becomes necessary.
PP tapes labelled “easy printable” are commercially available (e.g. tapes coated with any of our Release ST series products: see below). This means they are already treated by producers with special lacquers making the surface capable of receiving inks.
Tapes: PP (PET, PE) pre-treated with RELEASE ST or similar.
Printing machines: SIAT L 33 V, SIAT L 44
Products | Packaging | Quantity to apply |

COLOR INK PP PAM+ADD.* | Packed in 10 - 20 kg drums | Depending on printing necessity |
* Normal PAM inks (COLOR INK PP PAMC) can also be used, by adding our ADDITIVE ST2 (50 pp ink - 50 pp additive)
Tapes: in PVC.
Printing machines: SIAT L 33, SIAT L 44

COLOR INK PP PVC | Packed in 10 - 20 kg drums | Depending on printing necessity |
Tapes: BOPP or PE corona treated (38 - 42 dyne/cm).

COLOR INK WN | 25-200 kg drums, 500-1000 kg tanks | water |
Three steps:
These types of release agents have been developed for adhesive tapes producers, in order to allow printers to use single pass printing, only with special inks (COLOR INK PP PAM + ADD.).
Specific technical brochures are available with technical information for tape producers.
