DeltaBio's offers two types of packaging, PAIL-PAC, and VAC-PAC. PAIL-PAC means the specimen is packaged submerged in a solution and transported in a plastic pail or jar. This method allows for convenient storage and re-using specimens, but has more expensive shipping costs. VAC-PAC means the specimen, when moist, is vacuum-sealed in a Mylar coated polyurethane bag. This method has lower shipping costs but is less convenient for repeated use and reusability of the specimen. In some cases, no packaging choice is available when Delta Biologicals has determined that a single packaging method is optimal.
