A sealed package's transmission of oxygen, water vapor, carbon dioxide, or other gas or vapor that is of interest because of its potential adverse effects on the package contents is determined indirectly, based upon the package's transmission of a different gas selected as a test gas. Helium is preferred as a test gas. The package's total transmission of the test gas is separated into its components of leakage through the package seals and permeation through the packaging material itself. The package's leakage of the gas of interest is determined based on its leakage of the test gas, in accordance with the molecular weights of the gases. The package's permeation of the gas of interest is determined based on its permeation of the test gas, in accordance with data correlating the permeation of the gas of interest and permeation of the test gas for the materials from which the package is made, and with package structure data relating to the size, shape, and disposition of the materials from which the package is made. The package's total transmission of the gas of interest is determined by adding its leakage and permeation components so determined. Such data may be used with other data to determine a packaged product's shelf life or its sensitivity to a gas of interest.

A carpet securement includes a polymeric body with a longitudally extending groove in its bottom surface. Tacks or other fasteners protrude upwardly through the body. The tackheads or other drive elements of the fasteners may be lodged within the groove and serve as a bearing element to help support that portion of the body bridging the groove. The body may also be provided with a downwardly projecting riblike support rail inside the groove to help support the body. A groove minimizes the weight of a polymer incorporated in the securement body and further permits flush seating of the fasteners without localized overstressing of the polymer. In an extrusion process useful in making the body or other polymeric elements, sizing dies are provided with devices for maintaining a fluid film between an extrudate passed through the die and the contact surfaces of the die itself.

A disposable container consisting of a tetrahedral-shaped chamber and a base member formed from a paperboard blank pre-coated with an adhesive layer and having folding guides at desired locations to provide the base with arms to hold the chamber. The chamber is formed from a segment of flexible plastic tubing, sealed at the bottom and sealed at the top on a line transverse to the sealing line at the bottom to form the tetrahedral-shaped chamber. The chamber is stably mounted on the base member, which provides a wide surface for supporting and protecting the tetrahedral chamber and also provides labeling surfaces for the container. Also set forth is a method for manufacturing and filling containers by folding a blank pre-coated with adhesive along pre-set folding guides to form a base member, attaching the base member to a tubing segment, sealing the tubing segment at one end, filling the tubing segment, and then sealing the other end of the tubing segment on a line transverse to the first sealing line, to form a tetrahedral-shaped chamber for the container.
