- an adhesive which comprises the said adhesive bond layer the adhesive agent generally used for dry lamination methods, such as a polyurethane type and a polyether type
- a gas barrier layer, a reinforcing layer, or the like may exist as an intermediate layer.
- the reinforcing layer has a role of complementing the strength characteristics of the laminated film.
- the resin constituting the reinforcing layer polyolefin resins such as polypropylene (PP) and polyethylene (PE), biaxially stretched polyethylene terephthalate (O-PET), biaxially stretched nylon (O-Ny), biaxially stretched polypropylene ( OPP) and the like.
- the thickness of the reinforcing layer is usually 5 to 50 ⁇ m, preferably 10 to 30 ⁇ m.
- the gas barrier layer has a function of imparting gas barrier properties to block gas such as oxygen and water vapor from passing through the laminated film.
- gas barrier layer examples include metal foil, a vapor deposition layer of aluminum or an inorganic oxide, a gas barrier resin layer such as ethylene-vinyl alcohol copolymer (EVOH), vinylidene chloride.
- EVOH ethylene-vinyl alcohol copolymer
- These gas barrier layers can be provided on one side of the film constituting the base material or the reinforcing layer, and are generally provided as an intermediate layer between the base material and the sealant layer.
- an inorganic oxide vapor deposition layer it can also be used as the outermost layer outside the substrate (the outermost layer on the opposite side of the sealant layer in the laminated film).

- the packaging bag of the present embodiment is formed by heat-sealing the above-mentioned laminated film with the sealant layer, and is excellent in non-adsorption and barrier properties of low molecular weight components. It can be suitably used as a packaging bag.
- the form of the packaging bag can be three-sided bags, four-sided bags, joint-attached bags, gusset bags, self-standing bags, etc. It is applicable without particular limitation.
- the spout When the spout is provided in the packaging bag of the present invention, the spout can be suitably used as long as it can ensure sealing performance by joining with the sealant layer of the laminated film constituting the packaging bag, more preferably, It is desirable to join the spout and the laminated film by heat sealing using a spout formed of a sealant layer of the laminated film and a heat-sealable resin.
- the spout may be inserted and heat-sealed while the laminated film is overlapped with the sealant layer inside, and a flange or boat-shaped melt may be formed at one end of the spout.
- An attachment base may be provided, and the flange or fusion base may be heat-sealed with the periphery of the hole provided in the laminated film or the inner surface of the opening of the packaging bag.
- Sealant materials were produced with the compositions shown in Table 1.
- the sealant material was manufactured by a method in which each material was melt-kneaded and then formed into a film having a predetermined thickness by extrusion.
- the COP, COC, and PE used in this example are as follows.
- Heat seal strength According to JIS Z 1526, the seal strength (N / 15 mm) of the heat seal part of the pouch was measured at a tensile speed of 300 mm / min and a width of 15 mm.
- the heat sealing condition is to heat and pressurize at a pressure of 0.2 MPa for 1 second at any temperature among 140 ° C., 160 ° C., 180 ° C., 200 ° C., and 220 ° C.
- Stable region of heat seal strength A temperature range including the maximum value of the heat seal strength measured in (1) and within which the difference from the maximum value is within 1 N / 15 mm is defined as the stable region.
- Examples 1 to 6 were excellent in heat seal strength and non-adsorption, and the tensile elongation was significantly improved compared to COP alone (Comparative Example 2) or COC alone (Comparative Example 7). .
- Comparative Example 1 in which 20% PE was blended with COP and COC, the improvement in heat seal strength was low, and the non-adsorbability at 40 ° C. for 3 months was lower than that of COC alone (Comparative Example 7).
- Comparative Example 2 using COP alone the temperature at which a sufficient heat seal temperature was obtained was as high as 200 ° C. or higher, and a stable region of seal strength was not observed. Moreover, the tensile elongation was low.
- the present invention can be suitably used particularly for packaging of contents containing fragrances and active ingredients such as foods and drinks, cosmetics, and drugs.
