For example, if I use a sharp packaging bag for children, it may be too sharp to wrap toys for ten years. So why don't the bags have rounded corners? Isn't that safer? In fact, there are the following reasons:

1、 Due to the limitation of technology, the folding of straight line is much faster than the processing of fillet in general process manufacturing. In addition, the packaging of right angle is easy to form a closed space, but the production of radian is more difficult. In addition, packaging equipment and so on will limit its packaging molding, for example, we often say aluminum foil bag packaging, the bag itself can only be designed into a large roll, and then the machine can only be closed by scissors clip for hot air, so the fastest way is to cut with a straight knife. If the arc mouth is used, accidents such as hook and hook will occur during transportation and transmission.

2、 Due to the characteristics of materials, the general process of paper packaging is folding and printing, so it is not as good as plastic or metal packaging materials. Therefore, this determines that the molding of paper packaging can only choose a simple structure. Once a more complex structure is involved, the paper can only be realized through higher folding and precise positioning, which is time-consuming It's a matter of strength.
3、 The limitation of design thinking. In the packaging design, the paper lamination and folding are all based on a relatively simple thinking mode, such as straight-line folding, etc. once other or irregular objects are involved, the difficulty of folding and pasting, as well as the understanding of knowledge structure and accuracy requirements are extremely high, which can not be mastered by ordinary designers. Therefore, this also determines the basic knot of paper packaging Structure.
4、 Rectangular and regular straight-line objects are relatively high and stable in storage. You can stack two boxes together, but it is difficult for you to stack two balls together. This stability and storage quantity also require the characteristics of product packaging, regardless of the milk bottles or egg shaped packaging on the market, but it is necessary in the serious transportation We need straight packing for transportation.
As for other plastic bags, this is simply limited by the convenience of processing, but it is also common in China. In fact, many design countries in the world have done good treatment, such as Japan, and so on. Many packages are rounded, and the process is relatively mature. In addition, there will be one more working procedure to increase the cost.
