Protecting Products with Desiccants

Whether added to the package or part of the packaging itself, desiccants absorb the culprits bent on damaging the product.

While in transit or in storage, products are vulnerable to destructive elements such as moisture or gas. Desiccants are designed to draw these elements away so that the product, when opened, is as fresh as it was the day it was made. A great variety of desiccants are available—pillows, beads, barrels, and even the packaging material itself can provide protection.


Designed to protect items during shipping, desiccants combat moisture damage and corrosion. Desiccants, which are packaged in paper bags, are made of clay beads that absorb moisture inside containers. Associated Bag Co., Milwaukee, WI.
 


A line of desiccants provides absorption of moisture, odor, or gas. The PillowPak line contains packets available in compact sizes from 0.25 to 14 g. Packets can be made from Tyvek brand spunbonded olefin, paper, clear film, and custom substrates. Small, pharmaceutical-grade desiccants are offered, as well as silica gel, molecular sieve, montmorillonite clay, activated carbon, and specialty blends. Desiccare Inc., Santa Fe Springs, CA.
 


 

A custom packaging solution protects effervescent tablets from moisture and breakage. The Effervescent-Pak provides durable, rigid packages with built-in moisture protection, eliminating the costs associated with inserting loose desiccant tablets and packets. The company also offers Diagnostic-Pak, which protects diagnostic kits and strips from moisture damage during shipping. United Desiccants, Belen, NM.
 


 

A company uses Tyvek brand spunbonded olefin for desiccant bags. The bags, made from Tyvek 1025BL, offer opacity, high permeability, and an attractive, uniform look. The bags are designed to be cost-effective, and can hold items other than desiccants, such as odor-absorbent materials and vapor corrosion inhibitors.

A desiccant plastic can be molded or extruded into packaging that has effective moisture-adsorbing capabilities. This desiccant technology is based on entraining desiccants such as silica gel or molecular sieves into a polymer before extrusion. Having the desiccant in the plastic package itself eliminates the sourcing, handling, placement, and inspection of desiccant packets. Capitol Specialty Plastics Inc., Auburn, AL.
 


A company has expanded its product line to offer a complete line of desiccant canisters. The SorbiCap Plus features 2½X the adsorption capacity of similar-size, conventional canisters, says the company. Other products include the company's DriCap and SorbiCap canisters. Multisorb Technologies Inc., Buffalo, NY.
