Why aren't mask packaging bags made with rounded corners?

In life, we see masks packaging bags mostly are made with right angles, almost never rounded corners. Actually, there's no absolute rule, it's just a common characteristic in paper packaging bags and is also subject to process limitations. Besides the above reasons, other factors also influence this. Below, Shunxingyuan Packaging, a professional flexible packaging manufacturer, will analyze this.

Firstly, there are process limitations. General manufacturing processes are much faster at folding straight lines than handling rounded corners. Additionally, right-angled packaging is easier to form a closed space, but curved structures are more difficult to produce. Furthermore, packaging machinery will also restrict the shaping of the packaging. For example, with aluminum foil bag sealing, the bag itself can only be designed as a large roll, and the machine, for hot air etc., can only be sealed using a scissor clamp. The fastest method is straight-knife cutting. Curved edges would cause snagging during transportation and handling.

Secondly, material characteristics. The general process for paper packaging is folding and printing, unlike plastic or metal packaging materials which have better formability. This determines that the shaping of paper packaging can only choose simple structures. Once more complex structures are involved, the paper can only be achieved through higher folding and precise positioning, which is time-consuming and laborious.

Thirdly, limitations in design thinking. In packaging design, the bonding and folding of paper are based on a relatively simple way of thinking, such as straight-line folding. Once other or irregular objects are involved, the difficulty of folding and pasting, as well as the level of understanding of the knowledge structure, and the precision requirements are extremely high, which most designers cannot handle. This determines the basic structure of paper packaging.

Fourthly, storage. Rectangular and certain regular straight-line objects are more stable and efficient to store. Two boxes can be stacked together, but it is difficult to stack two spheres. This stability and storage capacity also determine the characteristics of product packaging. Although there are milk bottles or egg-shaped packaging on the market, regular linear packaging is necessary for formal transportation.

As for other plastic bags, this is purely due to the limitations of convenient processing technology, but this is mainly common in China. In fact, many design powerhouses internationally have done a good job, such as Japan, where many packaging bags have rounded corners, and the technology is quite mature.
