SEALED PACKAGE BODY, AND METHOD AND APPARATUS FOR PRODUCING SAME

摘要

The invention is a sealed package body (1) including a first sealed portion (4) that configures a tubular film (2), which is formed by bending a belt-like synthetic resin film in a tube shape so as to make both side edge portions of the film overlapped and fusing an overlapped portion (3) in a longitudinal direction of the film, thereby storing a content (5), second sealed portions formed at both end portions (6) of the tubular film and formed by fusing each inside surfaces of the tubular film across an entire length of the tubular film in a width direction, and tying members (8) that are respectively formed at both end portions of the tubular film and tie both end portions that are converged together. According to the invention, a sealed package body that is sufficiently resistant to heating-induced damage during a production process and has excellent airtightness is provided.
