Sorbatech Adsorbent Products

Adsorbent packets, strip packs and bags

Flow Dry offers a variety of adsorbent products under the SorbaTech® brand. All of our packet, strip pack and bag products are constructed from durable, non-dusting fabrics (like Tyvek®) filled with a variety of active adsorbent media (such as silica gel, zeolite molecular sieve, clay or activated carbon). Many options are safe for food contact. Other sorbent fills and fabric combinations are possible—just ask!

Primary product types: packets, strip packs and bags

  • Packets sizes are based on fill weight. These range from 1/4 g to 10 g. This format is typically used in manufacturing processes where the packet is manually inserted into the product or container.
  • Strip pack sizes are also based on fill weight. These range from 1/4 g to 5 g. Strip packs are continuous strips of connected packets supplied on spools. This format is used on automated packaging lines that place individual packets in bottles. The number of packets on a spool varies by the adsorbent fill weight.
  • Bags are similar to packets, only larger. They range in fill weight from 10 g (approximately 1/3 "unit") to 1 pound (approximately 16 "units"). The "unit" is a measure of water capacity based on the performance of the specific adsorbent (desiccant). These are used for general desiccation, but they can be used in nutraceutical containers, ingredient drums, and also for large container/box packaging.
  • Container desiccants are a larger format, specialty type of bag. They range in weight from 500 g to 1,500 g, typically. These desiccant bags are used most often in shipping containers to prevent product damage caused by "container rain", or condensation during transit, especially by ocean.
