This materials paper added boron nitride nanosheets to cellulose nanofiber films as a possible oxygen-barrier food packaging material, reporting improved oxygen transmission and mechanical properties and low cytotoxicity in a cell line. It does not measure boron migration into food.
Key numbers
- This paper reports no numerical findings relevant to boron exposure.
Methods (brief)
Film casting with 0 to 5 wt% boron nitride nanosheets; oxygen transmission, mechanical and cytotoxicity testing.
Evidence fitness
Boron appears here only as a component of an engineered material. The paper does not support dietary exposure or toxicity claims for boron.
Limitations
Off-topic for boron exposure; no boron measurements in food, water or people. Supported by the Korea Research Institute of Chemical Technology and Ulsan city; no conflicts declared.
