Description
技术领域 technical field
本实用新型涉及用于物件或物料贮存的容器，具体地说，涉及一种带有窗口的包装袋。The utility model relates to a container for storing objects or materials, in particular to a packaging bag with a window.
背景技术 Background technique
传统的纸质包装袋由于其袋体不透明，因此消费者在选购时看不到包装袋内的物品。Because the traditional paper packaging bag is opaque, consumers cannot see the contents of the packaging bag when purchasing.
为了解决上述问题，有些生产厂家在纸质包装袋的袋体上设置一个或多个窗口，并用一片形状与窗口相匹配且面积略大于窗口的透明塑料薄膜或透明塑料片材将窗口封闭，从而在纸质包装袋上形成一个或多个透明窗口，使人们能够看到包装袋内的物品；但是这种纸质包装袋中，透明塑料薄膜或透明塑料片材的边缘通过粘合剂粘结于窗口的边缘上，粘合剂带有刺激性气味，并且会污染包装袋内的物品(尤其是食品)，另外，粘结处往往不够牢固，容易裂开，影响包装袋的密封性能。In order to solve the above problems, some manufacturers set one or more windows on the bag body of the paper packaging bag, and seal the window with a piece of transparent plastic film or transparent plastic sheet whose shape matches the window and has an area slightly larger than the window. One or more transparent windows are formed on the paper packaging bag so that people can see the contents of the packaging bag; but in this paper packaging bag, the edges of the transparent plastic film or transparent plastic sheet are bonded by adhesive On the edge of the window, the adhesive has a pungent smell and will contaminate the contents (especially food) in the packaging bag. In addition, the bonding is often not strong enough and easy to crack, which affects the sealing performance of the packaging bag.
发明内容 Contents of the invention
本实用新型所要解决的技术问题是提供一种带有透明窗口的包装袋，这种包装袋能够使袋内物品保持清洁，且结构牢固。采用的技术方案如下：The technical problem to be solved by the utility model is to provide a packaging bag with a transparent window, which can keep the items in the bag clean and has a firm structure. The technical scheme adopted is as follows:
一种包装袋，其特征在于其袋体由复合纸制成，复合纸由纸层、透明塑料薄膜内层和透明塑料薄膜外层构成，纸层上设有窗口，透明塑料薄膜内层复合在纸层的内侧面，透明塑料薄膜外层复合在纸层的外侧面；透明塑料薄膜内层和透明塑料薄膜外层将纸层上的窗口封闭，形成透明窗口。A packaging bag is characterized in that the bag body is made of composite paper, the composite paper is composed of a paper layer, an inner layer of a transparent plastic film and an outer layer of a transparent plastic film, the paper layer is provided with a window, and the inner layer of the transparent plastic film is compounded on the The inner side of the paper layer and the outer layer of the transparent plastic film are compounded on the outer side of the paper layer; the inner layer of the transparent plastic film and the outer layer of the transparent plastic film seal the window on the paper layer to form a transparent window.
通常，在窗口位置，透明塑料薄膜内层和透明塑料薄膜外层复合在一起；透明塑料薄膜内层和透明塑料薄膜外层也可以不相粘连。Usually, at the window position, the inner layer of the transparent plastic film and the outer layer of the transparent plastic film are composited together; the inner layer of the transparent plastic film and the outer layer of the transparent plastic film may not be adhered to each other.
上述纸层上可印刷上各种图文。Various pictures and texts can be printed on the above-mentioned paper layer.
上述透明塑料薄膜内层和透明塑料薄膜外层可采用双向拉伸聚丙烯薄膜(BOPP薄膜)或定向聚丙烯薄膜(OPP薄膜)。The inner layer of the transparent plastic film and the outer layer of the transparent plastic film can be biaxially oriented polypropylene film (BOPP film) or oriented polypropylene film (OPP film).
上述窗口的形状可以是矩形、圆形、椭圆形、扇形，或者是根据需要设计的其它任意形状。一个包装袋上可以设置一个或多个窗口。The shape of the above-mentioned window can be rectangle, circle, ellipse, sector, or other arbitrary shapes designed according to needs. One or more windows can be set on one packaging bag.
本实用新型由复合在纸层上的透明塑料薄膜内层和透明塑料薄膜外层将纸层上的窗口封闭，形成透明窗口，封闭窗口的透明塑料薄膜与袋体其它部分一体，无需经粘合剂粘结在窗口边缘，因此包装袋内无刺激性气味，并能使包装袋内的物品保持清洁，而且透明窗口结构牢固；由于复合纸的内层、外层均为塑料薄膜，因此在制袋过程中以及封口时可采用热封，减少粘合剂的使用，并使包装袋的结构更加牢固。The utility model seals the window on the paper layer by the inner layer of the transparent plastic film and the outer layer of the transparent plastic film compounded on the paper layer to form a transparent window, and the transparent plastic film for sealing the window is integrated with other parts of the bag body without bonding. The agent is bonded to the edge of the window, so there is no irritating smell in the packaging bag, and the items in the packaging bag can be kept clean, and the structure of the transparent window is firm; since the inner and outer layers of the composite paper are plastic films, it can be used in the production Heat sealing can be used during the bag process and when sealing, reducing the use of adhesives and making the structure of the packaging bag more firm.
