The invention relates to a metallized multilayer sheet material for packaging having a water vapour transmission rate of below 5 g/m.sup.2/day at 38° C. RH:90% comprising:

a water vapour permeable sheet substrate, and

at least two metallized layers, each covered directly by a solvent based polymeric coating layer,

wherein the cumulated metallized layers have an optical density of at least 2.5 and/or a thickness of at least 15 nm.

A substrate for use in an electronic skin is disclosed herein. The substrate comprises a base polymer layer, and a first intermediate polymer layer attached to the base polymer layer by a first adhesive layer. The first intermediate polymer layer comprises a first intermediate polymer in which electron-rich groups are linked directly to one another or by optionally substituted C.sub.1-4 alkanediyl groups. A first conductive layer is attached to the first intermediate polymer layer by a second adhesive layer or by multiple second adhesive layers between which a second intermediate polymer layer or a second conductive layer is disposed.

A tire-enhancement product has a container comprising a dissolvable packaging material; and a solute encased in the container that is inert to the solute. The container is configured to be placed in an interior volume of a tire, to which solvent can be added. The container is configured to dissolve when placed in a predetermined solvent, and the solute is configured to mix with the solvent to form a tire-enhancement mixture.

Provided herein are methods of molding thermoplastic polymers into optical elements. The optical elements in the form of cylindrical discs, semi-finished lens blanks or finished lenses are compression molded at high temperature typically above thermoplastic polymers softening temperature and under high pressure. The semi-finished lens blanks and finished lenses are molded using front and back glass molds inside a mold assembly which reshapes the cylindrical discs that are either previously molded or cut out from thick slab. Also provided are methods for producing single vision and progressive addition lens prescriptions.

A method of painting a vehicle according to an embodiment including a first member and a second member which includes a painting surface and which is made of a material different from that of the first member. The method includes acquiring an environmental condition and a painting condition when the first member has been painted, and determining an environmental condition and a painting condition for the second member, which are determined in advance so that a color of the second member and a color of the first member will have a sameness in view of the acquired environmental condition and painting condition for the first member, as the environmental condition and the painting condition at the time of painting the second member which may be used together with the first member.

A method for creating a carbon nanotube heater assembly includes creating a carbon nanotube heater with varying resistances and attaching the carbon nanotube heater to both carrier and encapsulating materials. Creating the carbon nanotube heater with varying resistances is accomplished by applying a carbon nanotube mixture to a substrate, adjusting the thickness or width of the carbon nanotube mixture, and drying the nanotube mixture.
