Application

food packaging letterpress single and multi-colour printing wet-on-dry with inter-unit drying or wet-on-wet with final drying

 

Quality characteristics during printing

• fast curing speed

• low misting

• very good mileage by optimized pigmentation

• low migration when processed properly

 

Substrates

Paper, board Plastic fi lms: PVC, PS, PE, PP (if necessary with pre-treatment)

 

Storage

Product should be stored cool and dry in a dark place. Shelf life in unopened tins is 6 months.

Pantone®-mixing inks:

Nearly all shades of the Pantone®-colour guide are available on request.

 

Application

J+S UV LMI products are recommended for the production of food- and pharmaceutical packaging. The products indicated are formulated in such a way as to minimise potential migration through the substrate or the set-off from the printed outer side to the food contact surface in the stack or the reel, having taken into account the purpose for which they have been designed. Note that set-off and migration are also dependent on the processing conditions and suffi cient barrier properties of the substrate. The formulation considers low odour and low migration. The inks are only suitable for indirect food contact.

 

The inks are generally suitable for the packagings for following food:

• All kind of odour and taste sensitive food

• Solid, paste like or liquid, greasy or aqueous food

 

Excluded application

J+S UV LMI products are not permitted for direct food contact. Furthermore the application for food packaging which is determined for microwave or baking oven is only admitted, if special appraisals for this application are available.

 

Substrate

J+S UV LMI products are suitable for many various substrates. However, because of the variety of substrates own pre-tests especially regarding adhesion are necessary. If necessary the substrate should be pre-treated. In order to evaluate the migration barrier of the substrates please contact your supplier.

 

Production and composition

The products listed above are manufactured in accordance with the EuPIA „Good Manufacturing Practices for the Production of Packaging Inks formulated for use on the non-food contact surfaces of food packaging and articles intended to come into contact with food (GMP)”. Inks and varnishes are formulated with polymere photoinitators and/or initiators with low migration potential. Raw materials like fast curing binders are used which are almost completely included in the ink layer after curing.

 

Compliance with regulations

The manufacturer of the complete end-product and the packer are legally responsible for the appropriateness of the food packaging for its use in accordance with the regulations.

 

Application instructions

Inks: Depending on the ink application we recommend curing with a radiant engergy of at least 25 mJ/cm² in order to achieve a completely cured ink layer. We recommend and ink application of 1,0 – 1,5 g/m².

 

Varnishes:

For using in coating units we recommend a application of 2 - 6 g/m². The cell volume depends on the geometry, desired gloss and machine speed. The amount of the varnish should not exceed 6 g/m.

 

Overprint varnishes for using in ink units, we recommend our application instructions for „Inks“.

 

Further processing

Because of the resistances of the inks they can be UVvarnished. Furthermore they can be laminated and printed by thermo transfer.

 

Note

We recommend an inspection of the finished food packaging by an approved institute and we point out that not only the applied material but also the fabrication process can have an infl uence on the conformity of a packaging.
