In order to have technical characteristics, such as printability or sealability, plastic films must be coated with a varnish that will give these properties. As the market moves towards more specificities, it becomes imperative to develop custom-made varnishes, responding to increasingly precise specifications.
You can develop your own varnish using our facilities, via our two equipments that meet your requirements. The two machines are:
-Solvent based solution equipment: the machine is called DISOL2, suitable for resins that dissolve in hydrocarbon solvents (ethyl acetate, methyl ethyl cetone, etc.)
-Equipment for aqueous based solution called DISOL1, suitable for resins that dissolve in water. We use here demineralised water.
For these two equipments, we must respect minimum quantities of solutions in order to obtain a good homogeneity of the product.
The characteristics of these 2 devices are different

Equipment DISOL1 DISOL2
Maximum capacity per batch 2000 L 2500 L
Minimum capacity 1000 L 850 L
Temperature of heating 95°C 60°C
racking gravity pump

This equipment produces 393 T of solution year-round.
These two devices are either thermally insulated for Disol 1 (heating by circulating oil inside a spiral surrounding the tank) and by circulating hot water for the Disol 2.

In the case of solution in small quantities, they are carried out on mixers and containers adapted to the volume.

Mixtures produced by this equipment are done at the request of customers.
We control the supply of the majority of raw materials (resins).
Some solutions to be added are provided, ready to use, by the customer.
Sometimes the equipment is “blocked” to wait for additional products provided by the customer.
For all products, we draft with the customer, the specifications concerning the physical characteristics.
For some products, an infrared analysis is requested. This analysis is an integral part of the certificate of conformity and is attached to the BL.
With the material available at the glue workshop, we are able to meet the solution in virtually all resins
We avoid using CMR products (according to Reach legislation) in our workshops if we do not have an alternative, all precautions for the use of these products are put in place.
