Mode of Action: The proposed oil barrier
mechanism of the BIM Dual Barrier Concept
shows a cross section of 昀椀bre product with BIM
Oilguard™ in the 昀椀bre matrix and BIM Barrier™
coated on the surface.
Customer values of BIM Dual Barrier
•
Superior oil- and grease resistance
•
Protects against oil penetration through 昀椀lm/surface
coating defects and edge wicking
•
Enables low-weight barrier coatings
•
Additional barrier properties, e.g. moist (WVTR), water
and oxygen (OTR) resistance.
•
Re-pulpable and recyclable
•
Food contact approved BfR XXXVI, FDA 176.170
•
Compostability can be achieved
With BIM Dual Barrier Concept, similar OGR resistance
as PFAS treated 昀椀bre based packaging can be achieved with a
substantially higher sustainability pro昀椀le.

OGR test methods
The industry standard of via 3M KIT method is widely used
for testing OGR on 昀氀at and folded surfaces. 3 M KIT method was
developed mainly for measuring treatment of 昀氀uorochemicals. In
recent years alternative methods such ASTM F- 119 and CobbUnger oil absorbency tester have been widely used. In contrast to
3 M KIT method the latter methods use more realistic test oils and
are more adequate for estimating oil penetration and evaluating
ef昀椀ciency of barriers and wet end additives.
Collaborative action for a sustainable future
In conclusion, fostering collaboration between producers
and chemical suppliers is crucial for advancing sustainable and
functional 昀椀bre based food packaging solutions. Producers should
be able to expect comprehensive support and consultancy from
their chemical partners, particularly regarding application setup
and optimization. It is important for chemical suppliers to provide
cost- and time ef昀椀cient tools to assess the function of the different
solutions for grease and oil resistance before committing to a full
scale test.
