<P>PROBLEM TO BE SOLVED: To provide a resin sheet for an impulse-type heat sealer, capable of effectively preventing a to-be-sealed object from being transferred with a pattern undesirable in terms of appearance, and to provide an impulse-type heat sealer furnished with the resin sheet. <P>SOLUTION: A rectangular resin sheet 16 is formed by impregnating a fluororesin 23 in a fiber structure 20 which is formed by mutually knitting a plurality of first filaments 21 extending in parallel to one another in a first direction A1 and a plurality of second filaments 22 extending in parallel to one another in a second direction B1 crossing the first direction A1, wherein the first direction A1 and the second direction B2 are made to cross the longitudinal direction L of the resin sheet 16. Thereby, for the first filaments 21 and the second filaments 22, as development of variations in slackening tendency can be prevented, transfer of a pattern undesirable in terms of appearance onto a to-be-sealed object due to slackening only some of the filaments can be effectively prevented. <P>COPYRIGHT: (C)2009,JPO&INPIT |
