Holland Colours Profile


Holland Colours Product Formats for PET

Non-polymeric solids – Holcobatch & Holcoprill

Liquids - HolcoPET

High opacity masterbatch - Holcomer

to benefit from

Optimized processability

Economy of colouring

Optimal productivity


UV & Light Protection


Many colourants and vitamins as present

in food and juices are sensitive to UV-

radiation

Liquid detergents often contain colourants

that are sensitive to UV

Exposure to UV radiation from sunlight

and fluorescent lighting in retail outlets

significantly affects product integrity

UV Protection


Holland Colours has developed a range of cost-

effective UV absorbers in the range from 370 nm

up to 400 nm

The resulting UV-protected PET containers have

excellent clarity and optimal product protection

UV light protection can be combined with any

colour for optimal package design

Additional product protection can be

accomplished by combining UV-absorbance with

oxygen scavengers

UV Protection


Most types of beer are sensitive to UV

radiation and visible light up to 510 nm - the

'Light-struck' effect or ‘Skunked flavor’

This involves the formation of 3-methylbut-2-

ene-1-thiol (3-MBT) out of hops

3-MBT has an extremely low taste threshold

(4 parts-per-trillion) which means that the

smallest amount in beer makes its presence

noticeable

Light Protection - Beer


Light Guard Series

Holland Colours has developed a

series of bright colours with specific

light absorption up to 490 nm, 510

nm or higher.

Designed to be compatible with

commercially available oxygen

barrier resins

Available shades: Yellow, Green,

Orange, Red, Amber and Black


Two green colourants with

specific UV and visible light

absorption up to 490 nm and

even 510 nm

Designed to be compatible

with commercially available

oxygen barrier resins

Colour is very close to

existing glass bottles of major

beer brands

Light Guard Series – Green

protection required


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.

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”.

3

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.

Light Protection - Milk


High-concentrated solid format

Recommended dosing level 5 - 10%, depending on application, required opacity and wall thickness

Generates a white monolayer bottle that blocks 100% UV radiation and up to 99% of visible light

Key product features

Holcomer UHT White


Higher opacity than

resin based concepts

Adjustable dosing

level allows for

further light -

weighting

Molded & blown on

standard monolayer

equipment

Holcomer UHT White


Some products need even better

light performance than monolayer

solutions can offer

Typically less than 0.001% light

transmission (total darkness!)

Prelactia Overmolding is an

effective solution

Holcomer UHT White

Absolute Light Barrier


Netstal Prelactia 2-layer

overmoulding system

Specially developed White &

Grey Holcomer grades for

this application

Requires a specialized

multilayer preform moulding

system

Holcomer UHT White


Range of commercial applications in Europe and the USA with leading dairy companies

Variety of UHT and ESL milk types and flavored milk drinks in a range of different bottle designs

Several new market introductions in Monolayer and Overmoulding globally in 2013

Holcomer UHT White


Spray Frost Application

Low efficiency - Two step process
