The following are the tips for packing cartons from the inside, outside and bottom:
The sealing machine seals the bottom of the carton.
Prepare a special packaging carton, put the bottom of the carton firmly and fold it neatly, seal the carton into a "Tian" shape along the middle and four sides of the bottom, and finally reinforce it again along the sides, and affix a tear-proof label.
Start internal packaging
Open the upper part of the carton and put in the dust bag. Remember to seal the articles after they are put into the dust-proof bag, so as to play the role of dust-proof and waterproof.
The sealing machine seals the upper part of the carton.
After the internal packaging is completed, start sealing the upper part of the carton and repeat the bottom sealing operation.
