Printing Processes
Universal printing process (3 passes)
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
Special printing process (2 passes)
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 KF 100) becomes necessary.
Simplified process (1 pass)
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)
