DESCRIPTION
Mid viscosity semi-gloss and matt varnishes with excellent release properties for ‘peel and read’ and linerless release applications (please see list).

PROPERTIES
Excellent release. Good chemical and product resistance. Mid viscosity. Good adhesion. Not suitable for foil blocking / thermal transfer. Unless the printed layer is a barrier to migration and there is no possibility of set off to the unprinted (food contact) surface, standard release varnishes are not intended for food packaging specifications. For applications where the material is not a barrier, or set off is possible, we recommend the use of Low Migration inks & varnishes.  Pulse Roll Label supply inks and varnishes which have been formulated to comply with Food Packaging Legislation. Please see:-

Swiss List Eupia Information Note regarding the Swiss list.

EuPIA EuPIA information note on inks for food packaging. The raw materials are selected in accordance with the “Selection scheme for packaging ink raw materials” of the EuPIA Guideline. EuPIA 2 Regulation (EC) No 1935/2004

To achieve compliance it will be necessary to carry out a suitable evaluation. Please contact Pulse Roll Label for advice on this evaluation process. It must also be remembered that the manufacturer of the packaging and the filler are responsible for the properties of the food packaging and its compliance with legal requirements. The packaging ink suppliers are not able to issue certificates or declarations of compliance which cover the legal responsibility of others in packaging chain.
Note: It is important to note that the EuPIA Guideline recognises that the requirements are challenging and that there will be a need for a Continuous Improvement Strategy to control the potential migrants from packaging inks. It is envisaged that a significant period of time will be required in order to test, and where the required limits are not achieved, to generate an action plan that sets out a programme to ensure compliance within an agreed and manageable timescale.

In short, it is likely that testing will highlight issues that need to be resolved, necessitating a programme of improvement and retesting until compliance is achieved.

SUBSTRATES
Coated paper and board. Treated/primed polyethylene. Treated/primed polypropylene. Other materials after testing.  Please ask our laboratory, and/or send material samples, for more detailed advice and recommendations.

APPLICATION
General: -
Very important - stir / shake very well before use. Film weight: 6 volume anilox minimum. Rollers EPDM. UV Lamps: minimum 120 w/cm. Print speeds up to 80 m/min
Good results have been seen with non-absorbent substrates such as coated polypropylene. However, in order to get full release on paper or board substrates, a primer may be needed. Pulse can offer HD200 standard or BB9000 low odour UV flexo primers. Depending on the absorbency of the substrate, primer film weights of 6-20 volume are needed, with higher film weights needed for the more absorbent substrates. Trialling is essential.

NB - The most critical aspect to get smooth, consistent and repeatable release for all these products is the evenness and smoothness of application. It has been shown that increasing film weight of release varnishes rather than making the existing film weight smoother actually makes the release worse. After ageing, the release label may fail. This is true also for the application of any primer needed.
