The additive (Solarsorb) specifically formulated to give UV protection in both film and bottle packaging
has been found to reduce the vitamin A loss in milk by nearly 40% over a four day test. Milk tested was
filled into a HDPE (500μm wall thickness) and left under fluorescent light similar to the environment in a
dairy case at your local supermarket.
Angelo Spano modified the advertised topic to one that more generally addressed the packaging
industry and took a journey of ink from research to end user. Liquid inks have many applications for
flexography or gravure printing on packages across all segments of the packaged product spectrum.
The presentation started with the question: What is Ink? and moved through an overview of compliance,
application, correct ink choice and technologies for the future. The definition of ink as “a liquid or
paste containing various pigments and colorants used to produce markings” leaves much scope for
interpretation when trying to choose the correct ink for an application. Angelo advised the best solution is
to ask some fairly straightforward but basic questions. By walking customers through the journey above
(research to end user) it has been found that the correct choice of ink can be established if answers
to basics are provided. Does it comply with the needs? Has it the ability to achieve all requirements?
Can the press used meet the conditions expected? Are the technology directions compatible? These are
some of the questions that would be considered essential.
To ensure the various levels of compliance, all products have a material data safety sheet (MSDS) to
assist selection and ensure legal compliance. Ink manufacturers are conscious that their products are
a part of the overall environmental solution. Words like resin and solvents can be seized upon to wrong
effect so much research is being done to eliminate conjecture. Flint has undertaken extensive research
globally to explore environmentally friendly products and the results are remarkable. Inks are constantly
changing to meet ever changing demands and establish ‘green credentials’.
Market drivers for ink are no different than any other product used in packaging. Converters, retailers and
the consumer are the catalysts for change and there is no doubt that all are conscious of environmental
drivers.
So whether it be an additive for plastic resin or ink for glamorising a package it is important to work
toward commercial and environmental outcomes. The presenters fielded many questions with
professionalism and left the assembly in no doubt that they know their stuff.
Ralph Moyle the Southern Branch Chairman thanked Debra and Angelo and gifted them with a present
that encompassed both plastics packaging and printing inks.
