PINNACLE SERIES POLYESTER LAMINATION INKS

TECHNICAL INFORMATION

PINNACLE inks are formulated for reverse printing of treated Polyester film by the gravure process for subsequent adhesive lamination in combination with suitable adhesives.

SUBSTRATES:

PINNACLE inks are suitable for printing onto pre-treated or in-line corona treated Polyester film/primed polyester. Treatment levels should be between 38 and 44 dynes to ensure good adhesion. PINNACLE inks are not recommended for use with any other types of film.

LAMINATION PROPERTIES:

Printed Polyester film can be laminated with suitable adhesives to a range of substrates such as Polyethylene, paper or foil. The bond strengths achieved are a function of the substrate, adhesive type and the filmweight of adhesive applied. It is normally necessary to achieve minimum filmweight of adhesive to achieve acceptable bonds. The required combination of print process, substrate and adhesive should always be evaluated before use.

COLOUR RANGE:

PINNACLE inks are available in a range of colours. The pigments used have reasonable lightfastness but may not be suited to extended exposure to direct sunlight. If this property is required it should be stated at the time of ordering and pigments of appropriate fastness will be utilised. Inks may not be resistant to all post printing conditions. Special requirements should be specified at time of order.

REDUCTION:

Normal: IPA/Ethyl acetate 30:70 Slow: IPA/Ethyl acetate/N-Propanol 30:50:20 Recommended printing viscosity 20 - 24 seconds Zahn 2 depending on press conditions.

PRESS CONDITION:

PINNACLE inks may be run at speeds of 50 to over 100 m/minute dependent upon press drying capabilities and the solvents used for reduction. The resins utilised in PLC inks are particularly suited to give good lamination bond strengths but do not have as good anti-blocking characteristic as other ink types. Thus, extra care should be taken that sufficient drying capacity is present, efficient chill rollers are used before the rewind and minimum rewind tensions are set, to minimise the risk of blocking. Printed reels should also be stored upright in a cool area if possible.

WASH UP:

Ethyl acetate.
