Friends who often visit the supermarket will find holes in the
Plastic Packaging Bags. These holes are very neat. Why should we punch holes in these intact plastic packaging bags? Punching plastic bags has the following functions:
First, the size of plastic packaging bags for toys to a certain range, you must punch. Prevent children from suffocating by putting air tight in their heads while playing.
2. General packaging plastic bags do not need to be perforated, but in order to release the air in the bag after sealing and avoid air occupying the space, the holes are punched and deflated. The air holes are generally punched in the bag body.
Third, the round hole or butterfly-shaped hole hit on the top of the bag is used for hanging, called the hanging hole.
In fact, perforating plastic packaging bags has many functions, one is for safety, and the other is to make it more convenient to use plastic packaging bags.
