Why is there a missing triangle on the other side of the biscuit package so that you can tear it easily?

This is definitely not an individual, but everyone. It is reasonable that manufacturers should save costs and save it!

there will be a fast triangle gap on the side of many food packaging bags. This gap is really to facilitate consumers to open food packaging without the help of special tools, such as scissors, teeth and so on. It can be easily torn without being affected by any factors. However, the product packaging with convenient tear mouth is often difficult to open without borrowing tools

The packaging bag of

biscuits is folded and heated on both sides of the packaging machine (the extra part on the back of the package, commonly known as the “middle seam”) and the temperature rise suture of the port (the two ends are similar to the sawtooth incision, commonly known as the “end seam”), as shown in the following figure

“middle seam” is not the appropriate part to open the package. Consumers are more used to opening the package from one side of the product. The zigzag “end seam” has the effect of convenient opening. You can choose to open it from any notch on the left and right sides, which means you can choose the size of the opening. The following figure

there will be more triangles because of the cutting step
because each separated package only needs to cut one knife
if you want to cut one more knife, you need one more machine and one more cost
it is precisely because you want to save cost

— it’s more convenient to make
