Eco-responsible desiccant for protecting goods in storage and transit
Micro-Pak Dri Clay® Kraft Biodegradable Desiccant Sachets protect goods from moisture-related damage during storage and transit by controlling humidity inside sealed packaging, cartons, containers, bottles and bags. Each sachet contains 100% natural bentonite clay in biodegradable FSC-certified Kraft paper and absorbs up to 40% of its own weight in moisture. Available in 1g, 2g, 6g and 17g sizes.
Sold in packs and priced per pack.
Where does Micro-Pak Dri Clay® Kraft Biodegradable Desiccant Sachets work best?
This product suits sealed packaging where you need to control humidity during storage, handling or transit while reducing plastic in the packaging stack.
- Footwear, textiles and leather goods where trapped moisture can lead to mould, mildew or odour inside cartons and retail packs.
- Electronics and small components where lower humidity helps protect sensitive goods from moisture-related damage in sealed bags, cartons or containers.
- Food, supplements and pharmaceutical packaging where FDA-compliant contact suitability and a plastic-free sachet support regulated packing requirements.
- Metal parts, tools and machinery components where non-corrosive moisture absorption helps reduce the risk of rust during warehousing or export shipping.
Not for
- Open storage areas or unsealed cartons where air keeps circulating. Use a properly sealed carton or bag first, otherwise the desiccant cannot control the internal humidity effectively.
- Pallets, sea freight containers or long export routes on its own where moisture levels build across a larger freight space. Use carton-level sachets alongside calcium chloride desiccant.
- Non-sustainability-led packing where a standard synthetic desiccant is acceptable. For a conventional option, choose silica gel desiccant packets.

Choose the right desiccant
Micro-Pak Dri Clay® Kraft desiccants give you a plastic-free alternative to silica gel for carton, pouch, bottle and container-level humidity control.
- Choose Micro-Pak Dri Clay® Kraft desiccants when you need clay desiccant packs made from natural bentonite clay in biodegradable FSC-certified Kraft paper.
- Choose Micro-Pak Dri Clay® Kraft desiccants when your goods include textiles, footwear, leather goods, electronics, food, supplements, medical devices or metal parts.
- Choose silica gel desiccant packets when you need a standard synthetic desiccant for non-plastic-reduction packing lines.
- Choose calcium chloride desiccant when you need to manage moisture across a palletised load, sea freight shipment or freight container rather than only inside each carton.
Product FAQs
How much moisture does this desiccant absorb?
Micro-Pak Dri Clay® absorbs up to 40% of its own weight in moisture. The sachet controls water vapour inside sealed packaging, helping to reduce mould, mildew, corrosion and other moisture-related damage.
How do I use the sachets?
Place the correct sachet size inside the sealed pack, carton, bottle, bag or container with the goods. The pack must close properly so the sachet can reduce the relative humidity in the enclosed air space.
Is it safer to use with metal products than some desiccants?
Yes. The product is confirmed as non-corrosive and leak-free at full capacity, so it suits metal parts, tools and components packed for storage or transport.
Is the sachet biodegradable?
Yes. The sachet uses FSC-certified Kraft paper and natural bentonite clay. Biodegradability has been validated to ASTM D5511 and ISO 15985, with 90% decomposition within 30 days under test conditions.
Can it replace silica gel?
Yes, for many sealed packaging applications. It performs the same operational job as silica gel by absorbing moisture from the air, while using natural bentonite clay and a biodegradable Kraft paper sachet rather than a synthetic desiccant in plastic packaging.

- Export boxes help protect goods on long-haul routes and give desiccant sachets a sealed carton environment to work in.
- VCI bags let you place desiccants inside sealed electronics packaging rather than loose in the outer carton.
- Packing tape keeps cartons closed properly so the dry internal environment stays controlled during transit.
- Void fill helps stop sachets moving away from the goods they are there to protect.
