Definitions
- the present invention relates to a packaging bag in which the sides of two films having different functions are bonded together by heat sealing.
- the packaging bag of the present invention is a non-adsorbing film having thermal adhesiveness comprising 82% by weight to 90% by weight of an ethylene-vinyl alcohol copolymer and 10% by weight to 18% by weight of a maleic anhydride-modified polyolefin polymer.
- a functional film including a thermal adhesive layer made of 80 wt% to 20 wt% polyolefin and 20 wt% to 80 wt% maleic anhydride-modified polyolefin polymer, a non-adsorbing film and a functional film The heat adhesive layer is heat sealed and formed into a bag shape.
- the non-adsorbing film has a structure in which a maleic anhydride-modified polyolefin polymer is dispersed in islands, and the aspect ratio of the acid-modified polyolefin polymer dispersed and distributed in islands is 2.0 to 9. A range of 5 is preferable.
- the non-adsorbing film is preferably formed from a mixed resin obtained by polymer-alloying an ethylene-vinyl alcohol copolymer and a maleic anhydride-modified polyolefin polymer.
- the thermal adhesive layer may be a film formed from a mixed resin including a polyolefin resin and a maleic anhydride-modified polyolefin resin.
- the maleic anhydride-modified polyolefin resin is preferably 80% by weight or less based on the polyolefin resin.
- the packaging bag of the present invention since the non-adsorptive film and the functional film are heat-sealed, it is difficult for the scent component and the medicinal component contained in the non-package to be adsorbed to the packaging bag, and the functional film is In the case of a film having a hygroscopic function or an oxygen adsorbing function, it is not necessary to enclose a hygroscopic agent or an oxygen adsorbent in the packaging bag, and the packaging bag can be configured simply.
- the specific energy refers to the energy given from the melt-kneading equipment to the resin per unit weight (1 kg) during melt-kneading, and is a value obtained by the following formula. The larger the value, the higher the kneading effect. It will be.
- the torque, the kneader rotation speed, and the resin extrusion amount mean the following.
- Torque Force required to rotate the kneader screw Kneader rotation speed: Kneader motor rotation speed required to rotate the kneader screw per unit time
- Resin extrusion rate Kneader per unit time Amount of resin extruded from
- the screw shape and the resin extrusion amount affect the specific energy.
- the screw shape is a combination of a kneading part, a reverse flight part and / or a mixing part in the flight part, compared to the one using a general purpose screw only for the flight part (hereinafter referred to as a full flight type). It is desirable to use a material (hereinafter referred to as a high shear type).
- the film 2 having thermal adhesiveness can be obtained.
- An aspect ratio outside this range is not preferable because the thermal adhesiveness of the film is lowered.
- the functional film 3 has a characteristic of adsorbing gas components and moisture.
- the film 32 of the functional film 3 is a hygroscopic film, for example, a mixed resin containing a mixture of a desiccant such as zeolite and polyolefin, a polyethylene resin, and a maleic anhydride-modified polyolefin polymer.
- the functional film 3 having hygroscopicity can be obtained by laminating layers by a multilayer film forming method.
- polyethylene is used suitably.
- the non-adsorbing film and the thermal adhesive layer of the functional film were faced to each other, and the four sides were heat sealed at 160 ° C., 180 ° C. and 200 ° C., and the thermal adhesiveness (seal strength) of the resulting packaging bag was measured. .
- the thermal adhesiveness was measured with a T-type peel tester (STROGRAPE VE10D manufactured by Toyo Seiki Co., Ltd.) based on JIS Z 0238 for the seal strength of 15 mm width of the seal part.
- the measurement conditions are as follows. Distance between chucks: 10 mm, tensile speed: 300 mm / min
- the results of heat seal strength are shown in Table 2.
- the evaluation is “ ⁇ ” for 5N / 15mm or more, “ ⁇ ” for 2N / 15mm to less than 5N / 15mm, “ ⁇ ” for 1N / 15mm to less than 2N / 15mm, “ ⁇ ” for less than 1N / 15mm. Is shown.
- Examples 9 to 17, Comparative Examples 10 to 12 The resin composition and blending ratio of the thermal adhesive layer of the functional film were changed to the ratios shown in Table 3, and the sealing strength and blocking of the packaging bag were evaluated. The results are shown in Table 3.
- Evolu SP2520 (manufactured by Prime Polymer) is LLDPE, and Mersen MX02 (manufactured by Tosoh) is an ethylene-vinyl acetate copolymer compound resin.
- Modic DL2400 Mitsubishi Chemical
- Modic DU6400 Mitsubishi Chemical
- PET thickness 12 ⁇ m
- AL vapor deposition film thickness 9 ⁇ m
- non-adsorbing film laminated on the thermal adhesive layer of the functional film are the same as in Examples 1-8.
