Purpose and goal
Produce material fulfilling specified criteria: Coat weight 10 g/m2 (tot for 1-3 layers). FULFILLED Water vapor transmission rate < 50 g/m2d. FULFILLED Oxygen transmission rate < 20 cm3/m2d. PARTLY FULFILLED Fat resistance: < 1% staining. FULFILLED Perform an in-depth market and competitor analysis. PERFORMED Demonstrate technique for commercial production of barrier coated paperboard with existing application processes. DEMONSTRATED Establish a first agreement with commercial partner or financier for further development and market introduction of the product. ONGOING
Results and expected effects
CaiLar® is suitable as coating material for paper-based packages and the material does not adversely affect the taste quality of packed food. CaiLar® gives barrier properties which meet the market demands on a selection of consumer products and could partially replace the petroleum based plastic films used today. The project has also contributed to national growth by the consultation of several companies in the business area for production of material, pilot trials and analyses. A market introduction is expected to contribute to continued growth.
Approach and implementation
The set-up of the project with activities regarding technical verification has been performed according to the plans. The impact of several process parameters on the product properties has been evaluated. Commercial verification by market activities has been performed in parallel. Development towards a commercial product has been adapted during the project lifetime to match the product specifications demanded by the market, for example on packaging material with high fat resistance.
