New mailbox rules
It is understood that we have improved the way of packing belts. In production and use, the tape volume can be reduced by 30%. Our new standard box transforms a five-layer double-layer corrugated box into a three-layer single-layer corrugated box. Compared with the original standard box of the same size, the weight is reduced by about 20%. As of late September 2018, all major postal stores have been sold one by one. Later, the packaging tape was "tapered" and "tapered" from the original 48 mm tape to 45 mm. Later it was thought to use 40 mm wide tape at the same time. Various packaging is carried out according to the size and weight of the box. Use single characters, crosses, I characters, tic-tac-toe and other packaging methods.
