The construction and materials of Cali-5-Bond™ gas sampling bags ensure the physical integrity of any sample taken, it remains truly representative of its collection environment or medium conditions. Cali-5-Bond™ bags allow all samples to be stored without change over time.

In contrast to other single or multi-layer plastic materials currently in use, polymer Cali-5-Bond™ sampling bags are made by a patented production process bonding five different layers of material together into a single flexible sheet 5 mil (0.14 mm) thick. The absolute barrier to air, gas or liquid permeation is a layer of aluminum foil, a proprietary formulation of HDPE forms the totally inert and non-reactive inner-liner (wetted surface).
