Waterbased flexo inks for printing onto films, such as Polyethylene, Polypropylene, Vinyl, Foils etc.
WATER BASED FLEXO INKS
DESCRIPTION
Water based flexo inks designed primarily for narrow web presses printing self adhesive labels. Suitable for a wide range of substrates including films and papers.
PROPERTIES
Low viscosity, Water reducible, Excellent adhesion, Good water resistance, High colour strength, Excellent press stability. Pulse Roll Label RT series inks have been formulated to comply with Food Packaging Legislation. Please see:-
Swiss List Eupia Information Note regarding the Swiss list. 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. 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.
APPLICATION
Mix well before use. Anilox 90 - 120 l/cm. Cell volume 7-10 cm3/m2. Minimum dryer temp 500C with good air flow. Print speeds up to 150 m/min. Clean equipment immediately after use
SUBSTRATES
Coated papers and boards. Uncoated papers and boards. Coated/treated PE/PP. PVC. Polyester. Other materials after testing
GUIDELINES FOR USE
(Continued) Thermal Printing: RT inks are recommended. RV inks can be used on top coated thermal paper; however a varnish such as RT200 must be used to provide adequate heat resistance.
Laser Printing: Not recommended for laser overprinting. RT series should be used.
TTR/Hot Foil Printing: Although RW inks are most suited, with care, RV series can be overprinted with thermal transfer ribbons and/or with hot foils. Due to the number of different machines and materials, trials are always recommended to ensure full compatibility before production commences.
Varnishes: Application of a waterbased or UV varnish will enhance the appearance and resistance properties of RV series inks. Consult our technical department for the best varnish to meet your needs.
Cleaning: Anilox rollers and equipment should be cleaned with waterbased ink cleaner such as RLA394 Flexwash Aqua III wash-up.
ADDITIVES
Under certain conditions, additives may be required to ensure optimum performance: -
Retarder: Up to 5% RLA330 can be added when the ink is observed to be drying too fast, for example in warm conditions or when press speeds are very low.
Defoamer: Up to 3% RLA322 should be well mixed into the ink to destroy any excess foaming. Do not exceed 3% addition.
Print Aid: Up to 5% RLA324 can be added to the ink when used on long print runs to ensure pH is maintained at an optimum level.
(NB - Do not add RLA324 if running jobs where ‘Nestle-compliance' is required.)
Reducer/Accelerator: Upto 5% RLA325 can be added to the ink if it is too viscous. This will also help to speed up the drying of the ink.
Accelerator: Upto 5% RLA326 can be added to the ink to speed up the drying of the ink.
Thickener: Upto 2% HAW00104 can be added to thicken up the ink to aid transfer and reduce mottle. Be careful as 2% addition of HAW00104 will take 10 minutes to take affect fully in the ink, and the drying speed can be reduced by over-additions of this additive.
