Packaging bag quality assurance method

The first is the size of the measurement. The length and width of the packaging bag are very important, and some factories will increase the width of the bag to ensure that the bag can be used. The bag of this factory will be cheaper than other factories. Strictly, you must clarify in advance to avoid unnecessary loss of plastic bags.

In addition, the length of the plastic packaging bag is very important, and the gram weight is more important. The measure of its gram weight has a lot to do with the quality of the selected material. It is normal for the gram weight of each woven bag to be two grams up and down, so if you have a high demand for gram weight, please clarify to ensure that the lower limit of the gram weight can still be used. The above two are general methods to ensure quality.
