Definitions

  • the present invention relates to a packing envelope, and more particularly, to a packing envelope which is formed by adhering two film sheets together.
  • Packing envelopes using two resin-made film sheets are used for packaging articles.
  • Such packing envelopes are manufactured by placing an article between two film sheets and applying heat and pressure to parts surrounding the article to adhere the two film sheets each other.
