Norner microscopy laboratory analyse film structure, polymers, gels, seal quality and integrity to determine whether it is suitable for its intended use.
A key competence area of Norner is our advanced packaging development centre including film extrusion lines, MDO line, injection moulding and EBM machinery and a flexible and rigid packaging test centre with physical and analytical services.
Multilayer structure and composition
We can analyse film structure and polymer composition down to a very detailed level through combining the following strategies.
Sample preparation by microtome cutting of film cross sections.
Number of layers and thicknesses by light microscopy.
FTIR analyses of the whole structure as well as the inner and outer surfaces.
FTIR microscopy for analysing the type of polymer in each layer of the structure.
Hot stage Microscopy to determine the melting temperature and behaviour of each layer.
DSC analysis to determine the exact melting points of the structure.
SEM analysis for investigation of surface structures, inorganic fillers or aspects like laser score lines and perforations.
Material identification can be further supported by various polymer analysis.
Gels and inclusions are a classic problem of film production which can have a negative impact in several ways on the quality of flexible packaging. We have a long experience in identification and root cause analysis of gels by microtome preparations to reveal the cross section of gels followed by microscopy investigations and other polymer analysis, if required.
Analysis of seal quality and integrity
By investigating the cross sections of seals we can identify and validate the quality and integrity of seals in flexible packaging.
The microscopy lab has a number of microscopes using different techniques. We use incident light and transmitted light. Incident light microscopy is widely for surface analysis. Transmitted light microscopy is mostly used for morphological studies. Combination of these techniques give full services within research and development, failure analysis and trouble shooting for internal and external customers.
Contrast techniques for optical microscopy
Differential Interference Contrast
The different contrast techniques will contribute to more complete understanding of the material.
We strongly recommend “pre-check” by our experts, inspecting your product and or production designs before releasing products to the market.
Nobody likes failure, but one can learn much from solving problems. Norner has more than 40 years of experience in failure analyses and advanced material characterization. From our long experience with materials and products we have learned to recognize weak points much before these leads to product-failure under use.
Advanced microscopy analyses
Prototype product evaluations
Evaluation of mould designs
Evaluation of material use in challenging environments
In the field of microscopy the sample preparation is at least half the work. The results from the microscopy investigation is totally dependent of high quality sample preparation. In Norners microscopy lab we are fully equipped for many kind of materials and sample types.
Equipment for mounting of samples
Grinding and polishing equipment
With this equipment we can provide samples for all our different techniques. Method of preparation of samples will depend on material and scope of work. Our engineers have competence and experience with all kind of polymers and also a variety of other materials like metals, ceramics and composites etc.
Scanning electron microscopy (SEM) services is used for element mapping and visualization, surface finish, contaminations, failure and fracture investigation in all kind of solid materials.
Our laboratory has the insight to make microscopy investigation to provide documentation of materials and products. The SEM (Scanning-Electron-Microscope) is a special useful instrument when it comes to investigate and provide documentation of materials and products.
SEM-EDS testing areas
Consultations and problem solving
Product and material imperfections
Weakness in product design
Material and surface structures
Flow patterns build in stresses in plastic parts
Phase distribution of inhomogeneous materials
Together with our knowledge and experience Norner can offer a full-range analysis of organic and in-organic materials. We support all levels within research and development, operation and failure analysis. We can offer a broad and high-quality service within this field.
