When labeling, you first need to prepare labels suitable for carton packaging, and make sure that the size and adhesive of the label are suitable for carton packaging. Then follow the steps below to label:

1. Gently tear off the label, making sure that the back of the label does not touch, so as not to affect the stickiness of the glue.

2. Align the label with the position of the carton packaging, and gently press the center of the label with your fingers to ensure that the label is evenly attached to the surface of the carton packaging.

3. Use your fingers to push outward from the center of the label so that the glue of the label is completely in contact with the carton packaging.

4. Then use your fingers to carefully check all around the label to ensure that every corner of the label is firmly attached to the carton packaging.

5. Finally, gently wipe the surface of the label to ensure that the appearance of the label is clean and tidy.

Be careful when labeling, ensure that the label is attached to the correct position, avoid wrinkles or gaps, and ensure the neatness and integrity of the product packaging.
