FNP
SERIES INKS
TECHNICAL INFORMATION
FNP is a range of flexographic inks for printing polyethylene, polypropylene
and certain other films. They have been particularly formulated to take
advantage of the modern flexo press where clean running and fast drying
properties are required. Being alcohol based and hydrocarbon free they
are suited to today's food packaging specifications for such applications
as bread bags, deep freeze packaging, carrier and counter bags. For improved
half-tone printing the use of FNP inks is recommended.
SUBSTRATES:
FNP inks have good adhesion to a number of treated polyolefin films:
-
Low and high density polyethylene.
-
Two side treated polyethylene.
-
Certain cast, oriented and co-extruded polypropylenes.
-
Some cellulose films.
PROPERTIES:
-
Low odour and solvent retention.
-
Resistance to deep freeze.
-
Resistance to two side treatment and double side printing.
-
Anti-static properties and good slip for enhanced packaging performance.
-
Good adhesion giving scuff and abrasion resistance.
As the applications of flexo printed polyethylene (and other films)
are so varied the level of slip and certain other properties required
of FNP inks may be specified in discussion with our technical service
personnel. Where heat resistance is required PINNACLE or SIGMA inks should
be used.
COLOUR RANGE:
A full range of FNP colours is available which may only occasionally
be limited by pigment selection for specific applications.The colours
have a reasonable degree of lightfastness but may not withstand extended
exposure to direct sunlight. Where this property is required it should
be stated when ordering.
PRESS CONDITIONS:
FNP inks will print 50 to over 300 m/minute according to the reducers
used.
ROLLERS & STEREOS:
FNP inks are hydrocarbon free and may be used with normal rubber and
photopolymer plates and rollers.
REDUCERS:
The recommended reducers for FNP inks are: Normal: 74 OP meths Fast
: 9:1 meths:ethyl acetate Slow: 9:1 n-propanol:n-propyl acetate Care should
be taken in using slow solvents to avoid retained solvent in the printed
web as even small percentages of "clean" solvents may cause unacceptable
levels of taint and odour.
WASH UP:
Meths:ester blend .
Note:
This information has been carefully compiled from experience gained in
field conditions and detailed laboratory testing. However, the product's
performance and it's suitability for the customer's purchase depend on
the particular conditions of use and the material being printed. We recommend
that customers satisfy themselves that each product meets their requirements
in all respects before commencing a print run. Since we cannot anticipate
or control the conditions under which our products are used, it is not
possible to guarantee their performance. We would point out that the information
provided here is only a recommendation, and may need to be altered to
suit the conditions and efficiency of the equipment employed. Coates Lorilleux
ink products are not designed for use in conjunction with those of any
other ink-maker or similar supplier unless agreed to in writing.
