The BIM Dual Barrier Concept - Sustainable Innovation for Barrier Technology
News Guide Content Texts for companies in the paper industry
The BIM Dual Barrier Concept is an innovative technology from the Swedish chemical company BIM Kemi AB to improve the oil and grease resistance of paper and board packaging.
The BIM Dual Barrier Concept combines two components:
• A wet-end treatment of the paper with the additive BIM OilguardTM. This water-soluble, cationic system is used in the pulp and reduces the penetration of oil by minimizing the capillary effect in the paper.
• A surface treatment with the water-based BIM BarrierTM dispersions. This coating is applied by spraying or other suitable technologies. It forms an additional barrier against the penetration of oil, grease, moisture, and oxygen.
By combining these two components, a very effective barrier against the penetration of oil and grease is created. The BIM Dual Barrier Concept is particularly suitable for packaging where uniform coating is difficult, such as 3D-shaped products or lightweight surfaces.

Advantages of the BIM Dual Barrier Concept
The innovative two-component system offers numerous advantages over conventional barrier technologies:
• Excellent protection against the penetration of oil and grease, even with coating defects
• Enables lightweight barrier coatings
• Additional barrier properties against moisture (WVTR), water, and oxygen (OTR)
• Recyclable
• Approved for food contact (BfR XXXVI, FDA 176.170)
• Compostability can be achieved
• Free of plastics and PFAS (per- and polyfluoroalkyl substances)
By using the BIM Dual Barrier Concept, the barrier properties of paper and board packaging can be specifically adapted to the requirements of the packaged goods. In many cases, plastic coatings or composite materials can be avoided.

Applications and Target Groups of the BIM Dual Barrier Concept
The BIM Dual Barrier Concept is interesting for all companies that fill oily, greasy, or moist food in paper and board packaging, such as:
• Baked goods like cakes, cookies, croissants
• Fast food and take-away products
• Ready meals
• Frozen food
• Snacks and confectionery
The BIM Dual Barrier Concept is also suitable for packaging of technical products and chemicals where reliable protection against the leakage of oils and greases is required.
