Needs of the Plastic Industry

Plastics market:

How to handle

these needs? Minimize cost of risk

“Fit for the purpose”

products

Low energy and low

waste solutions

required

Need for clear, factual

and evidence based

communication

Sustainability, e.g.

•Social responsibility

•Environment

•Commercial success ex: Weight reduction

• Recycling

Providing custom made

individualized solutions

Important to Understand Failure Criteria

Non

stabilized

Stabilized

Polymer degradation on

the surface: Cracks

Stabilized Non

stabilized

Color fading of the red

pigment: Bleaching

Diagnosis on origin of failure is a must to optimize formulation

Packaging - Market trends

Trend to transparent packaging

Increased products exposure to

UV and Visible light

– Little to no UV filtering

– Limited and random protection

from visible light

Need for protection against light

Food - Beer, Milk, Juices, Sliced meat, Detergents & Shampoos

Pharmaceutical

Cosmetics

MB Asia 2012

Light - the enemy

An issue for many products categories

Causes undesirable changes of the packaged products

in appearance, color

in flavor or odor

in nutritional value

Compromises the aspect and the quality of the

packaged products

Affects negatively the brand image

Limits ingredient/product/package development choices

Shortens the product shelf-life

Returnable Packaging:

Crates performance properties during use

e.g. Outdoor stacked bottle crates

Performance requirements:

Color light fastness

Colors capable of overcoloring regrind

Polymer UV stability & oxidation resistance

Wash-resistance

Dimension control (warping)

MB Asia 2012

Crates, HDPE: Reduce Warping with

Low Warping Pigment

Red-1: Warping Red-2: Improved warping behavior

with low warping pigment

PE-HD injection molded crates: red pigmented PR 254

Maintain dimensional stability and provide productivity improvement

High demand on stackability
