り返し蓋片を有する袋体の提供にある。[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a bag body having a foldable lid piece, and its purpose is to enable the foldable lid piece to be opened and closed frequently and to prevent the bag body from being opened accidentally. It has a foldable lid piece that prevents both bags from sticking to each other and damaging the bag when the bags are stacked in multiple layers with the opening open or when they come into contact with other bags. It is provided by the bag body.
（従来の技術）
従来、開閉自在の袋体としては以下のような袋体が挙げ
られる。(Prior Art) Conventionally, the following bags can be cited as openable/closeable bags.
■ 袋体の一部にホックを設け、このホックを掛合して
開口部の封緘を行なう袋体。■ A bag with a hook attached to a part of the bag to seal the opening.
■ 袋体の開口部に弱粘着剤層を設けて、この粘着剤を
介して袋体の開口部の封緘を行なう袋体。■ A bag in which a weak adhesive layer is provided at the opening of the bag and the opening of the bag is sealed via this adhesive.
■ 袋体の開口部の一部から折り返し蓋片が延出し、封
緘時に於いてこの折り返し蓋片と前記袋体とが当接する
両面に弱粘着剤層を設けて、両粘着剤層を介して袋体の
開口部の封緘を行なう袋体。■ A folded lid piece extends from a part of the opening of the bag body, and a weak adhesive layer is provided on both sides where the folded lid piece and the bag body come into contact during sealing. A bag that seals the opening of the bag.
（考案が解決しようとする課題）
しかしながら、■の袋体に於いては、ホックの結合強度

破損する恐れがあった。(Problem to be solved by the invention) However, in the case of the bag (■), the connection strength of the hook is too strong, so there is a problem that the joint between the hook and the bag is easily damaged when used repeatedly. Yes, ■ and ■
Because the bag uses a weak adhesive layer, there is a risk that the opening may open accidentally, and if the adhesive is too strong, it will be difficult to open the bag when necessary. There was a risk that the bag would be damaged.
更に、開口部が開いた状態で袋体を幾重にも積み重ねた

の創出が望まれていた。In view of the above-mentioned circumstances, in the industry, it is possible to make the foldable lid piece open and close frequently and prevent the bags from opening accidentally. It has been desired to create a bag having a folded lid piece that does not cause damage to the bag due to adhesion of the two bags to each other when the bag comes into contact with the bag.

ト重合体と等量以下が適当であり、架橋剤の配合量はア
クリル系ポリマー１００重量部当り約１０重量部以下が
適当である。The total amount of the tackifier and softener is preferably equal to or less than the amount of the graft polymer, and the amount of the crosslinking agent is approximately 10 parts by weight or less per 100 parts by weight of the acrylic polymer.
また、粘着特性を微調整する目的でアクリル系ポリマー
等の種々のポリマーを配合してもよい。Furthermore, various polymers such as acrylic polymers may be blended for the purpose of finely adjusting the adhesive properties.
その他の任意配合成分としては、例えば酸化防止剤、紫
外線吸収剤、充填剤、顔料、増量剤等の感圧性粘着剤に
通常配合される添加物を挙げることができる。Examples of other optional ingredients include additives that are usually added to pressure-sensitive adhesives, such as antioxidants, ultraviolet absorbers, fillers, pigments, and extenders.
尚、その配合量は通常量であれば良い。Incidentally, the compounding amount may be a normal amount.
アクリル系粘着剤層（５）の厚みは特に限定されないが
、通常５〜１００μとするのが適当である。The thickness of the acrylic pressure-sensitive adhesive layer (5) is not particularly limited, but it is usually appropriate to have a thickness of 5 to 100 microns.
この考案に於いて前記アクリル系粘着剤層（５）と前記
被粘着層（６）との相対粘着力を１５０ｇ／２０ｍｍ以
上とする理由は、１５０ｇ／２０ｍｍ未満であると粘着
力が弱く、不慮に袋体（２）が開口する恐れがある為で
ある。In this invention, the reason why the relative adhesive force between the acrylic adhesive layer (5) and the adhered layer (6) is set to 150 g/20 mm or more is that if it is less than 150 g/20 mm, the adhesive force is weak and undesirable This is because there is a risk that the bag body (2) may open.

着剤層（５）との粘着性が良好な素材が望ましい。In this invention, the material of the adhesive layer (6) is not particularly limited as long as the relative adhesive strength with the acrylic adhesive layer (5) satisfies the above conditions, but generally an acrylic adhesive layer is used. (5) A material with good adhesion to the material is desirable.
特に例示すればポリ塩化ビニリデンフィルム、ポリ塩化
ビニルフィルム、金属蒸着フィルム、ポリエステルフィ
ルム、各種粘着処理フィルム等が挙げられる。Particular examples include polyvinylidene chloride film, polyvinyl chloride film, metallized film, polyester film, and various adhesive-treated films.

被粘着層（６）を除く前記袋体（２）との相対粘着力が
１００ｇ／２０ｍｍ以下、好ましくは５０ ｇ／２０＋
ｎｏ＋以下となることが望ましい。In this invention, the relative adhesive strength between the acrylic adhesive layer (5) and the bag body (2) excluding the adhered layer (6) is 100 g/20 mm or less, preferably 50 g/20+
It is desirable that it be no+ or less.
その理由は、相対粘着力が１００ｇ／２０＋ａｍを越え
ると開口部が開いた状態で袋体を幾重にも積み重ねたり
、他の袋体と接触した場合、両袋体が互いに付着し、無
理に引き離そうとすると両袋体が損傷する恐れがあるか
らである。The reason for this is that if the relative adhesive force exceeds 100g/20+am, if the bags are stacked in multiple layers with the openings open or come into contact with other bags, both bags will stick to each other and will not be forcibly separated. This is because if you try to do so, both bags may be damaged.
