After applying a center seal using a so-called electrostatic seal,
To provide a package in which a packaged object is inserted and front and rear seals are applied by corona discharge treatment or coating with silicone resin or printing ink on a part or the entire inner surface of the parts that become the front and rear seal parts. By doing so, the above objectives were achieved.
