Title:
ミクロフィブリル化セルロースおよびナノ粒子を含むフィルムの製造方法
Document Type and Number:
Japanese Patent JP7149282
Kind Code:
B2
Abstract:
A film comprising microfibrillated cellulose, nanoparticles, and a retention polymer. The nanoparticles are nanosilica nanoparticles that are anionic at neutral or alkaline pH and have at least one dimension less than 100 nm; and the retention polymer is starch. According to the present invention a high amount of nanoparticles is used as an additive, optionally together with a retention polymer.
