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. Packet or sachet sizes range from 0.25 grams all the way up to 112 grams, with coverstock materials including Tyvek®, Teijin Unisel®, 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 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).

Are you looking for uncoated Tyvek® coverstock with an edge weld?

The main manufacturer of uncoated Tyvek® desiccant packets no longer supports production of edge welded product, but edge weld technology is standard for IMPAK's StayDry™ desiccant packets. Why? Many of our customers use specifications that require this style of packet, and some dimensions are difficult to achieve with the "strip pack" style sachets that are the default for other brands. Strip pack style desiccant packets have additional coverstock material at the top and bottom; edge welded packets minimize packet size with the same quantity of desiccant medium inside. The reduced amount of coverstock material used has many benefits at scale, and the edge weld on IMPAK's desiccant packets provides a more secure seal. Speak to one our representatives if your production needs require edge-welded desiccant packets.
