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.

其他原材料的物理結構形式限制了其他發展的可能性。

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

除了上述第一種那樣直接開一個扣手在紙袋表面外，其實很多外賣紙袋是有提手的，一般這種提手的結構要么就是開一個圓洞穿繩，要么就是直接把手提繩粘在外賣紙袋的表面。

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.

開圓洞是因為它要配合之后要穿過并且承重的手提繩材料，如果是方形的洞他的承重面就會比圓形的少，壓力就會比圓形的更大，那么斷裂的可能性就會大大提升。

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.

從外觀上的美學來說，四四方方更加適合于科技感以及硬度很高的設計包裝，外賣紙袋廠家做出來的產品一般都沒有那么高強的硬度，因為它里面裝的東西有可能會略大，把紙袋撐開一點點也很正常，而且這種柔軟型的制品并不像紙盒那樣是死板固定好的，所以在開孔上也盡量使用圓潤的圓口開洞設計。

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.
