Humidity-constant Packaging Design Based on Spongy Polyurethane-poly(acrylic acid-acrylamide) Intelligent Material
Huang Hongjun · Packaging Engineering · 2012
A package material integrating humidity constant property and buffer function together was designed based on self-made spongy polyurethane-poly(acrylic acid-acrylamide)(PU-PAA/AM) humidity constant intelligent material.The method and formula to realize constant humidity in packaging internal environment through control of pre-absorption time was put forward according to the relation between moisture content and pre-adsorption time,and equilibrium moisture content and relative humidity.The packaging material integrates buffer function and humidity constant property together,so it is can be widely used in weapons storage packaging and transportation.
