Norner offers advanced OTR, WVTR and CO2TR barrier calculators with several features.

These calculators are being continuously improved with new features. The calculators are available on a separate web platform in simpler free and an advanced paid version. 

Norner Barrier Calculator

Geometry - film, cup, bottle and cuboid

Barrier calculations can be carried out on different geometries; film, cup, bottle and cuboid. This enables you to simulate your target package design. The calculating models gives you estimates of the O2 (oxygen), Water Vapour and CO2 Transmission Rate of various plastics packaging material like PP, PE, PET, PA and EVOH.

These barrier properties of coextruded, co-injection multilayer and in-mould-label solutions can be studied and evaluated by adding layers of the geometry or IML.

The combination of geometrical options, permeability properties and environmental conditions provides a useful tool for design and development.

• You can now add a sequence of conditions as you experience in the logistic chain with different temperatures and humidity.

Calculating steps

• Define packaging type and geometry parameters (e.g length, radius, height, width)
• Define layers, choose materials and thickness
• Add as many layers as needed
• Define environmental conditions (temperature, humidity)
• Alternatively, add more conditions in a sequence
• Push “calculate” and view the calculation results

Norner performs very many standard tests/datasheet tests of virgin materials and recycled materials.

• Mechanical properties according to ISO / ASTM standards
• Pigment and polymer characterization
• Chemical characterization
• Food migration OML/SML

Performance tests

• Processing trials of various bottles by extrusion blow moulding
• Bottle by one layer structure and up to three layer co-extrusion
• Online leakage test
• Thickness distribution
• Bottom weld performance
• Drop test
• Top load
• Test Method for Environmental Stress Crack Resistance (ESCR) (ASTM D2561-95)

Blow moulding

There are numerus polymeric and plastic products used in any building. This range from products like plastic membranes, surface coatings, insulation and electrical to water supply and plumbing. All of these applications require durability and specific properties for their use. We test and support the producers and the building industry with a wide range of relevant testing:

• Material characterization and specifications
• Durability testing
• Fire testing
• Mechanical testing
• Environmental exposure testing
• Recycling evaluations
• Failure analysis
• Third party testing and verification

Norner helps protecting the homes of our customers, reducing failures and saving costs.

We offer a specified test scheme for pre-qualification of pipe conduits for pipe-in-pipe systems.

When installing water distribution in domestic houses and apartments, the PEX supply pipe will be covered by a corrugated pipe, often called a Pipe in Pipe system.

The inner pipe is a PEX plastic pipe with very stringent regulations. The outer corrugated sleeve has a security function of leading away potential leaking water, if the PEX pipe gets a rupture. These tubes had no regulations until recently, and due to quality variations and problems of the tubes it has resulted in cracking tubes and several insurance claims.

Testing methods

A new test scheme, Sintef Byggforsk “Test method for pipe in pipe systems, for approval", has been implemented in Norway and includes the analysis of several quality parameters:

• Pigment dispersion and homogeneity
• Raw material quality vs. gels
• Thickness distribution of the profile
• Presence of notches in the tube profile
• Stress-crack resistance
• UV testing

Norner offers pre-qualification according to the above mentioned tests of the pipe-in-pipe systems. Qualified systems have to be sent to Sintef Byggforsk to obtain a Sintef technical approval.
