A port system for allowing transfer of material between sterile environments in two walled enclosures includes film members attached to each of the enclosures and covering ports through the walls of the enclosures. The exterior surfaces of the film members are coated with adhesives of a type which will cause the film members to adhere when brought into contact with each other. To transfer material, the enclosures are brought together with film covered ports in alignment, and upon contact the adhesive covered surfaces cause the film members to adhere. The film members are constructed and arranged so that the portions covering the ports in the walls of the enclosures can be separated from the portions surrounding the ports. After adherence, the separable portions are removed, enabling transfer to occur through the now open ports. Since the adhesive surfaces of the film members are the only surfaces exposed to the outside atmosphere, when they are brought together in adhering relationship, each effectively covers the exposed surface of the other, thereby preventing contamination of the sterile environments maintained in the enclosures.
