Description
また、本発明は、一対のヒートシールロールによって長尺の筒状のラミネートフィルムを挟み込み、該筒状ラミネートフィルム内に充填された液状物を、該一対のヒートシールロールによって絞り出しながら、その絞り出し位置の対面するラミネートフィルムどうしを融着接合する液中シール方法において、前記ラミネートフィルムとして、少なくともベースフィルム層とシーラント層とからなり、該シーラント層が、最外層となる高流動性熱可塑性樹脂フィルム層と、該高流動性熱可塑性樹脂フィルム層の前記ベースフィルム層側に位置する内側に積層された低流動性熱可塑性樹脂フィルム層とからなるものを用いて、前記一対のヒートシールロールによって、前記高流動性熱可塑性樹脂フィルム層の軟化・溶融温度以上、前記低流動性熱可塑性樹脂フィルム層の軟化・溶融温度未満の温度に加熱・加圧することにより、該高流動性熱可塑性樹脂フィルム層のみを軟化させると同時に、その軟化部分およびその近傍に付着介在している前記液状物を、該ヒートシールロールによる加圧によって押し退け、該押し退け位置に、該液状物の存在しない前記低流動性熱可塑性樹脂フィルム層の面を露出させると同時に、その露出によって対面する該低流動性熱可塑性樹脂フィルム層どうしを融着接合させてヒートシールすることを特徴とする。 Further, the present invention sandwiches a long tubular laminate film with a pair of heat seal rolls, while squeezing out the liquid material filled in the tubular laminate film with the pair of heat seal rolls, the squeezing position In the submerged sealing method of fusion-bonding facing laminate films to each other, the laminate film is composed of at least a base film layer and a sealant layer, and the sealant layer is a highly fluid thermoplastic resin film layer serving as an outermost layer. And a low-fluidity thermoplastic resin film layer laminated on the inner side of the high-fluidity thermoplastic resin film layer located on the base film layer side, using the pair of heat-sealing rolls, By heating and pressurizing the softening/melting temperature of the high-fluidity thermoplastic resin film layer to a temperature lower than the softening/melting temperature of the low-fluidity thermoplastic resin film layer, only the high-flowability thermoplastic resin film layer is obtained. At the same time as softening the, the liquid material adhered to the softened portion and its vicinity is pushed away by the pressure applied by the heat-sealing roll , and the low-flowing thermoplasticity in which the liquid material does not exist at the pushed-out position. The surface of the resin film layer is exposed, and at the same time, the low fluidity thermoplastic resin film layers facing each other by the exposure are fusion-bonded and heat-sealed.
上述したように、本発明に特有の前記液中シール方法では、シールバー７による加熱、加圧によってシーラント層１１のうち、高流動性熱可塑性樹脂フィルム層４のみを押し退けると同時に、該押し退け位置に露出した、内側に位置する低流動性熱可塑性樹脂フィルム層３どうしを融着接合させてヒートシール部８が形成される。このため、ラミネートフィルム１のフィルム構成（積層構造）等に応じて、ヒートシールロール５ａ、５ｂの温度や圧力等のシール条件や、低流動性熱可塑性樹脂フィルム層３および高流動性熱可塑性樹脂フィルム層４の種類や厚み等の各種の条件を適宜選定する必要がある。 As described above, in the liquid sealing method peculiar to the present invention, only the high-fluidity thermoplastic resin film layer 4 of the sealant layer 11 is pushed away by heating and pressurization by the seal bar 7 and, at the same time, the push-back position. The heat-sealing portion 8 is formed by fusion bonding the low-fluidity thermoplastic resin film layers 3 located inside and exposed to each other. Therefore, depending on the film configuration (laminated structure) of the laminate film 1 and the like, the sealing conditions such as the temperature and pressure of the heat seal rolls 5a and 5b , the low fluidity thermoplastic resin film layer 3 and the high fluidity thermoplastic resin are used. It is necessary to appropriately select various conditions such as the type and thickness of the film layer 4.
一方、低流動性熱可塑性樹脂フィルム層３は、一対のヒートシールロール５ａ、５ｂによって、高流動性熱可塑性樹脂フィルム層４よりも高温で加熱される（ヒートシールロール５ａ、５ｂによってベースフィルム層２側から加熱されるため、ベースフィルム層２に近い低流動性熱可塑性樹脂フィルム層３は、高流動性熱可塑性樹脂フィルム層４に比べて高温で加熱される）ため、低流動性熱可塑性樹脂フィルム層３の厚みは、高流動性熱可塑性樹脂フィルム層４よりも厚くしておき、ヒートシールによって低流動性熱可塑性樹脂フィルム層３が薄くなりすぎないようにすることが好ましい。
On the other hand, low flow thermoplastic resin film layer 3, the base film a pair of heat sealing rolls 5a, by 5b, than 4 high flow thermoplastic resin film layer is heated at a high temperature (heat sealing roll 5a, the 5b Since it is heated from the layer 2 side, the low-fluidity thermoplastic resin film layer 3 close to the base film layer 2 is heated at a higher temperature than the high-fluidity thermoplastic resin film layer 4). The thickness of the thermoplastic resin film layer 3 is preferably made thicker than that of the high-fluidity thermoplastic resin film layer 4 so that the low-fluidity thermoplastic resin film layer 3 does not become too thin due to heat sealing.
