The results showed that value and air permeability of the prepared paper-based composites that depositing modified and of unmodified LCMNF were significantly reduced to and ?0 . 0 0 3 μ m/ （ P a? s） ，respectively，which were 16. 2 % and 0 . 0 2 % ofthoseoftheoriginal paper.Meanwhile，the kitvalue increased fromOto12，demonstratingasignificant enhancement in oil-proof performance.

目前，石化聚合物是食品包裝材料的主要來源之一，占比接近 5 0 % ，其中塑料薄膜因其優(yōu)異的防水性能和機(jī)械性能，成為食品包裝材料中的優(yōu)勢選擇但隨著社會的快速發(fā)展，人們逐漸發(fā)現(xiàn)廢棄塑料會對環(huán)境造成不可逆的負(fù)面影響，不僅會對生態(tài)環(huán)境造成危害，還會危及人類健康[2-3]。（剩余13900字）
