The circular design takes into account the fact that human fingers exhibit a semi elliptical shape with a curved curve in terms of human mechanics. If the portable part of the paper bag made by the delivery bag manufacturer is square, it will continuously squeeze the smooth curved side of the fingers, which will greatly reduce the user experience. Or it may cause customers to no longer use this delivery paper bag, reducing the exposure of customized delivery paper bags by merchants, which may at worst affect reputation and reputation due to customer loss.

其他原材料的物理结构形式限制了其他发展的可能性。

The physical structural forms of other raw materials limit the possibility of other developments.

除了上述第一种那样直接开一个扣手在纸袋表面外，其实很多外卖纸袋是有提手的，一般这种提手的结构要么就是开一个圆洞穿绳，要么就是直接把手提绳粘在外卖纸袋的表面。

In addition to the first method of directly opening a buckle on the surface of the paper bag mentioned above, many delivery paper bags actually have handles. Generally, the structure of these handles is either to open a circular hole and thread the rope, or to directly attach the handle rope to the surface of the delivery paper bag.

开圆洞是因为它要配合之后要穿过并且承重的手提绳材料，如果是方形的洞他的承重面就会比圆形的少，压力就会比圆形的更大，那么断裂的可能性就会大大提升。

The reason for opening a circular hole is because it needs to be matched with the portable rope material that needs to be passed through and bear weight. If it is a square hole, its load-bearing surface will be less than that of a circular one, and the pressure will be greater than that of a circular one, thus greatly increasing the possibility of fracture.

从外观上的美学来说，四四方方更加适合于科技感以及硬度很高的设计包装，外卖纸袋厂家做出来的产品一般都没有那么高强的硬度，因为它里面装的东西有可能会略大，把纸袋撑开一点点也很正常，而且这种柔软型的制品并不像纸盒那样是死板固定好的，所以在开孔上也尽量使用圆润的圆口开洞设计。

From the aesthetic perspective of appearance, the square design is more suitable for packaging with a sense of technology and high hardness. Products made by takeout paper bag manufacturers generally do not have such high hardness because the contents inside may be slightly larger. It is normal to stretch the paper bag a little bit, and this soft product is not rigidly fixed like paper boxes, So try to use a round opening design on the opening as much as possible.
