Abstract: The invention relates to a process for the bonding of a fiber-reinforced material to an injection-molding material. The invention further relates to an article produced according to the process. It is an object of the invention to improve the bond between a fiber-reinforced starting material and a material applied by injection. To achieve the object, a fiber-reinforced plastics material is heated locally, and further plastics material is applied by injection. This produces a particularly good coherent bond between the further plastics material and the fiber-reinforced plastics material. Ease of handling is also provided. The invention relates to a component produced according to the process and also to an apparatus for carrying out the process.

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.
