1. Bag material:
The bags need to be odorless. The bag with peculiar smell generally makes people feel that it does not meet the hygienic standard, and may affect the normal use of the bag. If there is no odor, it is necessary to check the transparency of the bag, whether the clarity is uniform, whether there is impurity feeling, etc.
2. Printing quality:
See if there is an obvious third color at the joint of the two colors. The higher the fidelity level of the physical image, the better. See if there are wire drawing, fogging, blocking and missing printing.
3. Appearance uniformity:
Watch the stiffness of the bag first. Generally, the higher the flatness, the better, except for the different needs of materials. For example, nylon and high-pressure film composite bag, the heat seal of the bag will be wavy; also need to observe whether the cut edge of the bag is neat, the more neat the better.
4. The firmness of the bag. The firmness of the bag can be divided into two types: fit firmness and hot air firmness. Because of different materials, the bags have different firmness. The first distinguishing method is to aim at the edge of the bag and tear it by hand. If it is difficult to tear, the heat seal is strong. Otherwise, it is not good.
