Abstract: The invention relates to an absorbent insert for foodstuff packagings, the liquid-absorbing component of which is a superabsorbent polymer which, in a hitherto unrivaled fashion, persistently absorbs and retains large quantities of liquid even under high pressure load, protects the foodstuffs from bacterial decay, and prevents contamination of the packagingd goods by migrating soluble constituents of the polymer. This combination of properties of the superabsorbers used is expressed by the QSAP 0.3 quotient of retention according to the tea bag test+absorption against pressure (AAP) 0.3, divided by the amount of solubles (LA), which quotient is at least 20. Superabsorbers having such properties are obtained by using special combinations of crosslinkers. Furthermore, the invention relates to a process for producing said absorbent inserts and their use in foodstuff packagings, as ice substitute, and as leak-proofing means in transport packagings.

Abstract: A method of manufacturing a multi-layered web uses contoured honeycomb drums for the manufacture of non-woven webs used to make the multi-layered web. The method can use spunbonded, melt blown, or electro-static spun techniques for depositing solidifying filaments on outer collection surfaces of a multi-drum system. The multi-drum system may be employed to improve multi-layered web uniformity and the overall quality of the multi-layered web by presenting a single optimal collection surface for each independent web layer being produced.

Abstract: A web of fibers is bound together by a bonding medium that has been activated by partially solubilizing the bonding medium with a solvent therefor. The fibers are insoluble in the bonding medium. As the bonding medium is partially solubilized, it becomes tacky and flows into contact with the fibers and with itself Thereafter, the solvent is absorbed by the bonding medium, allowing the bonding medium to resolidify and bond the fibers in a matrix, increasing the web strength.
