SunLase™ - Description

Sun Chemical has developed the SunLase™ range of inks which are sensitive to specific low energy lasers, allowing the marking of high definition variable data on various substrates.

SunLase™ inks contain specific pigments, that change from white to black when hit by a low energy laser. There is no ablation. This technology, combining laser and colour change, opens up myriad of opportunities to add value to printer, converter and brand owner printing requirements

SunLase™ range offers packers and end-users the platform to introduce greater efficiencies and productivity as well as higher quality on their identification marking applications

It allows packaging printers and converters to sell “activated” packaging at premium margins

SunLase™ range covers most of printing and ink technologies: flexo, gravure, dry and wet offset, water and solvent based, oil based, UV

SunLase™ - Key benefits

High definition quality at high speeds

Packaging can be nominally patch printed providing unique identifiers and personalisation

Reduces SKU’s considerably because marked and coded on demand. Product variants can be marked at the final production step

Without resetting any consumables

Improved print reliability, important reduction of defaults

Cost saving and flexibility are achieved by removing the need for secondary applications

Possible combination with brand security and anti-counterfeiting systems

Improved traceability thanks to high quality individual coding (2D Data matrix codes…)

Helps improving safety in food pack applications thanks to huge reduction of particulates

Reliability Industrial lasers are robust machines designed for use in demanding environments to minimise unplanned stoppages and maximise performance

High speed Laser coding provides a high quality code faster than the nearest equivalent

Repeatability Laser on SunLase™ patch produces a consistent code every single time.

Visual quality Lasers provide high contrast coding and high level graphics and fonts

Flexibility Marking variable data with the ability to change outputs instantly

Space utilisation Laser marking onto SunLase™ pre-printed patches enables better defined information to be seen and read clearly.

Modern process The latest laser technology enables a controllable minimal power to code and mark substrates that previously would have been damagedE

Minimal extraction

The SunLase™ patch causes far less particulates to be produced when laser marked compared to traditional laser ablation.

Food safety Thanks to huge reduction of particulates, very little impact on food packaging

Environmentally friendly

Minimal consumables and nothing secondary is added to the substrate, facilitating easier recycling.

Minimal consumables

Lasers do not use solvents or ribbons, and allow label elimination

Stock Keeping Unit (SKU) reduction

Codes and graphics directly applied to generic packaging stock on an ‘as required basis’ removes the need for specially pre-printed units

Waste reduction Strong reduction of waste of unused or obsolete promotional packaging thanks to 'print on demand' process

SunLase™ - Target markets and applications (2)

End-uses:

– High volume food producers with short shelf life products, for example:

milk: sleeves and labels yogurts: PET/PP lids and labels beverage: beer bottle labels

– Medium to high volume premium ranges: lids and labels, soups, granulated products,

– Personal care labels and sleeves– Toiletries, perfume bottle labels, shampoos, liquid soaps– Pharmaceutical labels, foils, blisters– Existing production of 5 million + outer cartons per year.– Current users of Hi-Resolution ink jet – Print and hand applied

labels– Businesses looking seriously at packaging innovations and

environmental issues– Businesses that suffer fines for poor barcode quality
