Extended exposure to visible light will initiate photo-oxidation of vitamins B6/B12 and riboflavin (vitamin B2). Very high light protection is required up to 550 nm.

1

2

In the case of milk, secondary degradation due to auto-oxidation of lipids (milk fats) results in off-flavours and nutrient losses, especially of vitamins. All this results in a specific “light taste”.

Effects of UV radiation & Visible Light on Food & Dairy- the Chemistry

Taste & nutrition protection can not be captured by mathematical formulas or generic data: taste & odor and analytical tests must be performed in the chosen package option.

Sustainability

The challenge

� In today’s PET packaging market there is a trend toward increasing the use of post-consumer recycled PET for theproduction of bottles, sheets and fibers

� This material often exhibits a slight tint or contains colored particles that affect the clarity of the material compared to 100% natural PET resin

� This lowers the value and limits thepossible application areas of the PCR resin

TintMask - Extending the Value of Recycled PETThe concept

� Holland Colours’ TintMask concept is based on the principle of complementary colours. The system is designed to effectively neutralize the discolorationthat is commonly present in recycled PET.

� TintMask product range is fully compliant with EU, FDA and Coca Cola Company directives.

� The concept is designed for the PET recycling environment, the components will not migrate or sublimate in a high vacuum process.

� TintMask products are available in liquid and solid formats.

TintMask - Extending the Value of Recycled PET

Benefits that make the difference

TintMask delivers significant advantages toprocessors and users of recycled PET:

� Increased sourcing flexibility

� Greater batch-to-batch colour consistency

� Added value to end users of recycled material

� No migration or sublimation in high vacuum processing

� On-site color adjustment at customer’s facility

Sustainability & Holcomer

Fact is that opaque white PET dairy bottles can significantly disturb clear PET bottle-to-bottle recycling1

All stakeholders are concerned by the potentially negative image of opaque PET2

A working group on opaque PET recycling has recently been created around COTREP (Comité Technique du Recyclage des Emballages Plastiques) in France

3

This group has taken the initiative to propose a Bottle to Bottle and Bottle to Fibre recyclability assessment protocol for each individual white opacifying solution

Bottle-to-bottle recycling currently is only valid for the light coloured/non coloured stream. Sorting of colouredfractions is key and can be achieved

1

Current main end applications for heavy coloured PET-recyclate: Strapping, Fibers, Sheet 2

Trials for recycling of 50% white Holcomer-based bottles into new white bottles have been successfully executed with PTI by means of a standardized protocol

3

Tests are under way with COTREP in France to assess the influence of the introduction of 50% white bottle chips coloured with Holcomer in the fiber process
