Our Products
Our product range contains a wide range of BOPP Self Adhesive Inks, Asterlam Inks, Reverse Printing Gravure Lamination Inks for Polyester Film, Two Pack AR Inks and quick drying marking ink
Asterlam Inks have been carefully formulated forGravureprinting on Reverse side of Polyester to offer sharp printability for Solid as well as half tone jobs on polyester film at varying press speeds. Good Adhesive lamination characteristics are in-built in these inks to make them suitable for lamination with polyethylene film, alumunium foil, paper and board to satisfy the needs of a variety of packaging applications. .
Technical Data and Working Advice
| SUBSTRATE : | Asterlam inks offer good adhesion on polyester film and are recommended for reverse printing jobs since the gloss and scratch resistance will be unacceptable for surface printing. |
| REDUCER : |
Ethyl Acetate & Toluene or as recommended to suit specific printing conditions. To accelerate the drying M.E.K. or Ethyl Acetate can be used with the reducer |
| RETARDER : | M.I.B.K. |
| WASH UP : | Ink reducer is suitable for press wash up. |
| COLOR RANGE: |
A variety of shades are available, produced with carefully selected pigments. New shades are matched on demand. |
| LAMINATION : | Asterlam inks are suitable for adhesive lamination with polyethylene film, aluminium foil, paper and board. Good lamination results are achieved.Lamination peel strength is dependent on adhesive used, adhesive coating weight, substrates laminated and to some extent nature of the job. It is therefore advisable that proper adhesive is selected and its coating weight is controlled in order to get best lamination results. |
Two pack multigloss inks have been formulated for flexo and gravure printing on treated polyethylene substrate, qualifying the aggressive alkali resistance test, making them suitable for detergent packing.
|
SUBSTRATE : |
Two Pack Multigloss inks offer good adhesion on treated polyethylene film to get optimum print properties. The treatment level should be kept at least 38 dynes/cm. |
|
INK CATALYST RATIO :
|
3 parts of catalyst is mixed thoroughly with 97 parts of ink prior to printing. Lower proportion of catalyst will lead to inadequate resistance property and excess catalyst will reduce the pot life of the ink. |
|
POT LIFE : |
Once catalyst is mixed and the ink is reduced for printing, the expected pot life is about 48 hours,after which the ink starts picking up viscosity. |
|
PRESSRETURNS : |
Returned inks from press need not be wasted. Press returns are mixed with reducer and used up. 1 part of press returned inks should be mixed with 4 parts of reducer and then be used as a reducer with the freshly prepared ink. |
| Ink Reduction | |
|
FLEXO : |
Usual reducer is N.B.A. or its blend with Isopropyl Alcohol. |
|
GRAVURE : |
Usual reducer is Toluene or its blend with Isopropyl Alcohol. |
|
WASH UP : |
Ink reducer is suitable for press wash up. |
|
RESISTANCEPROPERTY :
|
The prints, after a minimum of 48 hours of curing are kept immersed in 2% Aqueous Sodium Hydroxide solution for 24 hours.The prints are then rinsed under tap water and rubbed gently with cotton soaked in water. The print should not come off. Inadequate resistance property may result from the following, if care is not taken: (I) Treatment level of polyethylene film is lower than recommended. (II) Correct proportion of Catalyst is not used, or the Catalyst is not properly mixed. |
|
COLOR RANGE : |
A variety of shades are available, produced with carefully selected pigments to satisfy the resistance towards alkali. New shades are matched on demand. |
