MINI desiccant bags – specially designed for pharmaceuticals, food & diagnostics (FDA-compliant)

These particularly compact desiccant bags fit in almost any kind of packaging or components. Their tiny size (see → Table) and filling (either silica gel or a molecular sieve) mean they can be used flexibly for a wide variety of purposes.

Guaranteed to adsorb a high degree of moisture, this product is particularly ideal for pharmaceuticals and diagnostics, but is also well established in industry – such as electronics and optics (e.g. in compact casings and controls).

Mini desiccant bags – The desiccant

Standard MINI desiccant bags contain silica gel/white gel or a molecular sieve as the desiccant:

  • Silica gel provides reliable protection for the tiniest of packaging thanks to its high adsorption capacity at higher relative humidity (over 50% RH)
  • Molecular sieves are commonly used as desiccants in lower relative humidity (under 50% RH) and at lower temperatures, e.g. cold chains. A 4Å molecular sieve is used as a standard,  3Å, 5Å and 10Å/13X can also be used tailored to the required purpose

The desiccants are chemically neutral, and provide reliable protection against mould and rust.

Mini desiccant bags – The Tyvek® bag material

The MINI desiccant bags are made from hot-sealed Tyvek® - a highly resistant, durable material consisting of spun polyolefin fibres, and which has been used as packaging in pharmaceutics and diagnostics for decades.

The very tightly interwoven fibres guarantee a dust-proof product, while the surface of the Tyvek® desiccant bags is extremely wear-resistant and lint-free.

The standard printing on the bags complies with European Union regulations (Regulation EC No. 450/2009) and contains the warning “Do not eat” in German, English, French and Spanish.

Compliance: FDA & EU for pharmaceutics, food and diagnostics

Our MINI desiccant bags comply with international requirements regarding contact with food. Some products in the MINI desiccant bag range are registered with the FDA in a DMF (Drug Master File Type III).

Desiccants: The white-gel and molecular-sieve desiccants comply with

  • The requirements of the US FDA (Food & Drug Administration) regarding contact with food
    (incl. 21 CFR 174.5, 177.200, 182.1711).
  • European Union requirements regarding contact with food (incl. Regulation (EC) No. 1935/2004).

Tyvek® bag material: Tyvek®, as the bag material for the MINI desiccant bags, complies with

  • FDA regulatory requirements for polyolefins (21 CFR 177.1520) and additives (21 CFR 178.2010).
  • European Union requirements established in Regulation (EC) No. 1935/2004 regarding contact with food.

Printing ink: The ink used to print on our MINI desiccant bags

  • Complies with the requirements of the US FDA (21 CFR 73, 74 Subpart A, …), and
  • Is registered with the FDA in a DMF (Drug Master File Type IV).


MINI desiccant bags come in basic packets printed with usage instructions.

These packets consist of polyethylene bags, and comply with the requirements established in DIN 55473 regarding protection against water vapour. The extra packaging used for shipment consists of a resealable metal bucket with low water-vapour permeability, thus ensuring a long shelf life.

The MINI desiccant bags are also available in cardboard boxes.

Shelf life

MINI desiccant bags may be stored in a dry place at room temperature for extended periods of time without losing any of their effectiveness.

Every basic packet contains a moisture indicator for visual checks.

Shelf life in sealed packets:

  • Standard (in a metal bucket) – up to 24 months
  • In a cardboard box (optional)  – 6 months
