To be laid in the pan before use and flushed away afterwards, the tissues can be provided in interfold packs, or in pads of thin paper or foil shaped to correspond with the pan profile and to similar dimensions but large enough for part of the trap to be covered by them. The tissues can be crepe or other material soluble in water, possibly soluble plastic such as PVA or cellular material, and can be multilayer. |
