Gelok Superabsorbent Laminates for

Hazardous Materials

Gelok superabsorbent laminates for hazardous materials, including diagnostic and infectious substance transport, utilize superabsorbent polymers that absorb many times their weight in aqueous liquids and locks them in with high holding capacity. Because liquids are locked physically by hydrogen bonding, they will not be released, making the Gelok superabsorbent laminates for hazardous materials excellent for use in the shipping of infectious and dangerous substances. 

Features & Benefits

Gelok superabsorbent laminates are ultra thin while being extremely absorbent, therefore requiring less absorbent media. This can reduce associated shipping costs by utilizing smaller and less bulky containers, making Gelok superabsorbent laminates a cost effective solution for the shipping of infectious and other dangerous substances.
