Ammonia Water Barrier Property of "Soarnol®"

Ammonia water barrier property of "Soarnol®" is shown in the following.

(1)Test Method

Procedure:

1. nfuse a pouch with 100ml of 25% Ammonia water or distilled water(as reference)
2. Measure weight decreace with time at the condition of 20deg C,65%RH

Sample : 

Pouch made of monolayer or multilayer film consisting of Soarnol (Surface area:433cm²)

Film	Thickness(µm)
Monolayer film(Soarnol 32mol%)	30
Monolayer film(Soarnol 44mol%)	30
PP / Soarnol32mol% / PP	30 / 40 / 30

Result

Sample	Permeability(g 100µm/m2 day）
	Ammonia water	distilled water(ref.)
Soarnol 32mol%-Monolayer Pouch	20	25
Soarnol 44mol%-Monolayer Pouch	3.0	2.4
Soarnol 32mol%-Multilayer Pouch	2.4	0.4
