Desiccant Packets
IMPAK Corporation maintains inventory on many sizes of desiccant packets for use across varying industries. Desiccant packets are used to remove the residual water vapor remaining inside of a sealed container or package thus preventing hygroscopic products from experiencing the adverse effects of continuous exposure to water vapor or moisture. Ranging in packet or sachet size from 0.25 grams all the way up to 112 grams with packaging materials such as Tyvek and various woven and non-woven configurations all in stock at our Los Angeles facility.
The amount of desiccant required will vary by application and customer-specific needs such as type of packaging, type of product and amount of headspace and interstitial space after closing/sealing the container among others. Please contact a specialist at 310-715-6600 or flprocessing@impakcorporation.com to discuss your specific application and any special needs your project may have.
The table below shows the standard range of sizes for desiccant packets. If the specification for your application calls for a particular packaging material, IMPAK can accomodate that. Though the majority of these sachets are packaed with Tyvek®, other materials are available, such as Unisel® (found in packets sold by ULINE).
