  • a laminated film was manufactured by bonding an EVA series sealant film with a thickness of 50 ⁇ m together in which a weakness line with a width of 0.5 mm and a depth of 45 ⁇ m with 7mm intervals was formed beforehand. Then, the laminated film was cut to a width of 35 mm by a slit processing, thereby manufacturing a display strip.
  • a biaxial oriented polyethylene terephthalate film (PET film) with a thickness of 50 ⁇ m was used and corona treatment was conducted on one surface of a PET film.
  • anchor coating was conducted on a surface of the PET film subjected to corona treatment and to the anchor coated surface, natural rubber-based adhesives with a thickness of 50 ⁇ m were coated, thereby forming a pressure sensitive adhesive layer.
  • a laminated film was manufactured by a bonding sealant film with a thickness of 30 ⁇ m (m-LLDPE) at silicone coating treatment by a silicone treatment agent for peeling off manufactured by Dow Corning Toray Co., Ltd together so that the silicone coated surface and the pressure sensitive adhesive layer are faced each other.
  • silicone treatment was conducted so that the density becomes 100 dot/cm 2 .
  • the laminated film was cut to 35 mm in width by a slit processing, while at the same time, rule processing was conducted with 5 mm intervals, with a width of 0.5 mm and a depth of 25mm by a rotary blade, thereby manufacturing a display strip.
  • one surface of a biaxial oriented polyethylene terephthalate film with a thickness of 50 ⁇ m was subj ected to corona treatment, and to the corona treated surface, natural rubber-based adhesives with a thickness of 50 ⁇ m were coated, thereby forming a pressure sensitive adhesive layer.
  • an m-LLDPE film with a thickness of 40 ⁇ m was laminated, thereby manufacturing a laminated film. Then, the laminated film was cut to a width of 35 mm by a slit processing, thereby manufacturing a display strip.
  • a display strip was manufactured by the same method as Comparative Example 1 wi th the exception that thin paper (70g/m 2 ) was used as a substrate layer.
  • Pressure sensitive adhesive samples were prepared by bag materials in which 100 g content was heat bonded with display strips manufactured by Examples 1 to 5 and Comparative Examples 1 and 2 with a heat sealing temperature of 120°C, and with a sealing time of 250 m sec using a strip-pack device.
  • strip-pack devices those disclosed in Japan Unexamined Patent Publication 2004-90949 were used and as bag materials, films with a total thickness, that is, thickness of sealable OPP/ink/polyethylene/sealable OPP from the surface of 50 ⁇ m were used.
  • a display strip easy for automating the process of bonding product-enclosed bags and capable of bonding the product-enclosed bags once removed again can be provided.
