    摘要： In a plastic film heat seal apparatus in which a plastic film includes opposite side edge portions superposed with each other, the opposite side edge portions being heat sealed with each other longitudinally thereof, the apparatus is improved to make the side edge portions heat sealed with each other adequately not to be low in seal strength and not to be impaired in appearance. The apparatus includes a pair of heaters 5 disposed on opposite side edge portions 3. The heaters 5 have heating surfaces 6 to preheat the side edge portions 3, the heating surfaces 6 being spaced from and opposed to each other. A plurality of suction holes 7 is formed in each of the heating surfaces 6, the side edge portions 3 being attracted by the suction holes 7 to be brought into contact with the heating surfaces 6.
