- the patches may be a combination of such bands and strips. Said combination of bands and strips may be located on the inner, outer or both surfaces of the second sheet material.
- each of the sheet materials may be the same or different in composition from any of the other sheet materials.
- the first sheet material may have a thickness from 5 to 500 ⁇ m, for example 10 to 300 ⁇ m or 20 to 60 ⁇ m. However, materials having a greater thickness may be used in some configurations, for example longitudinally extending strips.

- the one or more adsorbent material and/or diluent stabilising means may be selected from any suitable material as known to skilled workers. Examples include zeolite, sepiolite, clay, activated alumina, minerals, resins, silica gel and carbon.
- the adsorbent material and/or diluent stabilising means is carbon, such as activated carbon. Where activated carbon is used, the activation level can be measured by evaluating the percent carbon tetrachloride (CTC) as is known in the art. Briefly, carbon is weighed, exposed to CTC and then the weight of the carbon remeasured. The increase in weight of the carbon is calculated as a percentage.
