PEL SERIES INKS

TECHNICAL INFORMATION

PEL series inks are formulated for Rotogravure and Flexo surface printing onto a range of films, paper and foil.

SUBSTRATES:

PEL series inks have good adhesion on treated polypropylene and pearlised OPP. To ensure good adhesion the minimum treatment should be 41 dynes/cm. PEL inks can also be printed over suitable white ink onto coated films such as MB777 for snack food packaging. This requirement should be advised to Coates Lorilleux before ordering. PEL series inks are also suitable for printing onto paper and NC coated aluminum foil.

PROPERTIES:

PEL series inks have good adhesion on a range of substrates giving good scuff and abrasion resistance. They are suitable for deep freeze packaging, although this requirement should be advised to Coates Lorilleux prior to ordering. PEL series inks are heat resistant from 120°C to 170°C and suitable for printing in heat seal areas. Colours will have a reasonable degree of light fastness, but may not withstand prolonged exposure to sunlight. If light fast inks are required this should be stated at time of ordering. PEL series inks are not suitable for lamination.

PRESS CONDITIONS:

PEL series inks can be printed at most printing speeds without problem. Where fast print speeds are used, it is recommended that efficient drying units and chill rollers are utilised. High rewind tensions are not recommended.

REDUCERS:

The recommended reducers for PEL series inks are:

Gravure: Normal: Ethanol/Ethyl acetate 1:1 Slow: N-propanol/N-propyl acetate 1:1

Flexo: Normal: Ethanol/Ethyl acetate 4:1 Slow: N-propanol/N-propyl acetate 4:1

Retarder: Glycol ether can be used at maximum 5 % for most applications but must never be used on MB777. The user should be aware that glycol ether can significantly increase solvent retention on all substrates. If printing onto coated Polypropylene films such as MB777 it is recommended that reducers with a maximum 20% ester are used to avoid solvent retention and poor over printability. Isopropyl alcohol can be used to replace ethanol under some circumstances although this may be detrimental to the printability.

ROLLERS AND STEREOS:

Being alcohol rich, PEL inks for Flexo application can be run with most normal rubber rollers and stereos. Photopolymer plates may also be used with high alcohol diluents, but this should be discussed firstly with our technical service personnel to ensure the correct formulation is being supplied for these plates.

WASH UP:

Alcohol ester blends.

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.
