CSP Technologies Activ-FilmTM materials enhance product stability in ways that are invisible to consumers and more efficient for manufacturers.

The flexible materials are ideal for use in applications like foil pouches, stick packs and blister packs in industries such as Pharmaceutical, Diagnostic, Food, Electronics and Optics.

Flexible film formats

Activ-FilmTM materials are available in configurations like rolls, die cut pieces and adhesive-backed labels. Film thickness typically ranges from 0.3 to 1.2 mm, though CSP can customize configurations to meet a wide range of size, shape, and packaging automation requirements.

Activ-FilmTM formulations can absorb a variety of gasses, including moisture, oxygen, and volatile organic compounds. Activ-FilmTM materials can also release gasses such as carbon dioxide (CO2) and chlorine dioxide (ClO2) to serve as anti-microbial agents.

Formulated for performance, CSP’s range of Activ-FilmTM materials can be tailored to meet specific requirements.


  • Moisture Adsorbing – Available in a molecular sieve formulation (designed for lower relative humidity) or a silica gel formulation (ideal for applications prone to over-drying).
  • Oxygen Scavenging – These films do not need moisture and are effective at any relative humidity. CSP’s oxygen scavenging films can consistently reduce and maintain O2 levels to below 1%.
  • Combination Films – Available as an oxygen and moisture-scavenging combination, these compounds provide one solution for multiple sorption needs.
  • Specialty Formulations – CSP can produce films that absorb odors or volatile organic compounds. CSP also can make films that dissipate aromas or antimicrobial agents such as chlorine dioxide, carbon dioxide and AIT (allyl isothiocyanate).

Regulatory Compliance

A number of Activ-FilmTM materials are specifically formulated to comply with U.S. Food and Drug Administration (FDA) and European Union guidelines for Food and Drug Contact. Activ-FilmTM material formulations are described in CSP Drug Master File #14789.
