Flexible Packaging Quick-fire product Q&A with DataLase
DataLase has expanded its coatings and substrate application offering by launching a new coatings range for laminated constructions called SB Lamination Coatings. Technical sales manager Tim Bedford explains.
W
hat are the main benefits of DataLase within laminate constructions? Packaging robustness, ingress resistance and a tamper proof solution that relates to track & trace. Also, brand integrity as alternative solutions can be easily removed from surface print.
What press printing speed is capable for inks/ coatings application?
The DataLase solution is common to flexographic and gravure solvent based standard applications e.g., 20-600mpm, dependant on application, processing, and drying capabilities.
Which types of solvent are compatible with the inks/coatings?
Standard flexographic and gravure blends and, dependent on processing requirements, TSDA / alcohol and esters, as referenced on data sheets.
Can SBG inks/coatings also be used with water based inks/coatings?
Yes, should processing capability support both technologies, then this is possible.
What are the pre-press preparation and running requirements?
Standard premixing with industry mixer prior to press application. Automatic viscosity system compatible, or through standard Zahn monitoring during production.
Are there any press cleaning down considerations?
Standard cleaning down with normal solvents after inks/coatings removed from press application systems, with residue disposed of as standard.
Once inks/coatings have been on press, can they be stored and reused?
Yes, storage and reuse advisories verified on data sheets for shelf life and in line with printers’ in- house process procedures.
Are there any considerations for inks/coatings and surface tension, adhesion properties to substrates?
Standard dyne level assessment for solvent based applications of minimum 38 dyne/cm.
Are there examples where DataLase solvent based ink/ coatings can be integrated and provide secure improvement to products?
The DataLase solution lends itself to a number of substrate materials across a variety of markets including food and beverage, home and personal care, pharmaceutical and medical on a range of multi and mono polymer layered laminated substrates such as pouches, booklets and leaflets. Substrate compatibility includes:
O Surface and reverse print dependant on whether clear or coated films.
O Uncoated and coated paper and board. O Aluminium Foil. OPolythene, polypropylene, polyester. O P.V.d.C Coated, P.V.C, Metalized films.
Is the DataLase solution multi-layer compatible? Yes, it is suitable for multiple-layer variable material laminates including barrier films e.g., metalized. Also, increasingly advantageous for environmentally friendly recyclable objectives e.g., multi-layer mono material.
Can inks/coatings also be surface printed on to a base primer and be used to overprint standard inks/coatings?
Yes, viability and assessment advised through technical contact.
Can solvent based, water based and UV OPV’s be applied over laser inks/coatings? Yes, viability and assessment advised through technical contact.
Which lamination processes are compatible with inks/coatings?
Print industry standard lamination processes such as solvent based, water based, extrusion, UV, EB, cold seal (pressure sensitive) and heat seal etc.
Are inks/coatings flood coat and patch print register compatible?
Yes, both are acceptable applications, standard bespoke press register systems have no issue in inks/ coatings recognition.
What are the manufacturing supply chain benefits associated with adopting DataLase technology vs alternate C&M Solutions? Modern high level concerns bearing improvements in lean manufacturing - eliminating waste, improving quality, and reducing costs, reducing time, and with a full QC system installed, less rejects back to suppliers and non-conformances. Coding and marking benefits include flexibility, speed, future proofing on customisation requirements and more.
What colour changing mechanisms are available and what laser hardware is required? O SBG-5304 – White to Black colour change - CO2 10.6-micron c/w.
O SBG-5334 – White to Black colour change - Fiber 1064-nm c/w.
O SBG-9304 – Clear to White colour change - CO2 10.6-micron c/w.
O SBG-9334 – Clear to White colour change - Fiber 1064-nm c/w.
Are there any restrictions for laser imaging quality and speeds regarding DataLase inks/ coatings?
None associated with inks/coatings, upper limit for bespoke application verified independently through laser hardware systems @ 500mpm for alphanumeric, data matrix, QR.
There is also flexibility to achieve higher laser imaging rates through supporting laser hardware systems aligned to 500-1000mpm speed requirements.
