New coating solves a sticky problem for Norprint

/live/stories/norprint.jpgA new Apticote coating from Poeton Industries has helped label printing specialist, Norprint, solve a sticky production problem with a self-adhesive paper.

Norprint Labelling Systems is one of Europe's largest independent labelling companies with a capacity of 6.7 billion tickets, tags and labels every year. The company operates thirty presses including digital, rotary, flexo, letterpress and custom designed machines.

Several of the label presses operate a re-lam and de-lam process that peels the backing paper from a self-adhesive stock, allowing the machine to print onto the adhesive. It then joins the two substrates together again.

The stock can stick to the rollers when the machine is running, and in order to minimise the problem, Norprint had been covering the rollers with a layer of silicone paper.

"The search for a solution took us to the Internet, where we found the Poeton website," explains Norprint production manager, Malcolm Keightley.

"We then phoned Poeton and discussed the problem with coating specialist Trevor Amos, who recommended Apticote 810SP - a coating that has been specially designed for print and packaging applications involving adhesives.

"Poeton has been very helpful and the whole process has been easily managed by email, telephone and post."

Initial indications at Norprint show that Apticote 810SP is helping to increase production and reduce costs and material wastage. It is expected that Apticote 810SP will be used on six machines, possibly more - with other rollers due to be sent for coating.

Says Trevor Amos, "Following the original contact they sent us one roller for coating, which we returned for testing. The self-adhesive stock ran without sticking and there was no drag from the material. They were so impressed with the results after a one month trial that they sent another six rollers for coating, which are now fitted and operational on three presses."
