This standard is consistent with German Standard DIN55522--1987 "Packaging materials--Folding cartons with inserted bottoms and lids--Dimensions of paper cones (German version)" and is adopted with modification. Compared with DIN55522-1987, the main technical differences of this standard are as follows: - The applicable weight range of cardboard from 220g/m2 to 500g/m2 is changed to 200g/m2 to 500g/m2, the definitions of "insertion type", "bottom feed type" and "white lock bottom type" are added, and two side cover sizes are added, with the sizes of 2.5mm and 4mt~6mm respectively; - When the sealing edge size B≤12mm of the bottom surface of the paper box, the calculation relationship between the depth f of the tongue plate, the radius of the arc of the tongue and the width c of the pasting edge is added (see Table 2);
\ - The value range of the pasting edge width c is modified, and the pasting edge width \c≥10 mm\ is changed to \10 mm≤c≤16 when the sealing edge size of the bottom area of ​​the paper box is "B≥12mm" in Table 2. mm\;--The contents of the packaging storage and transportation part have been deleted;--Taking the reverse plug-in folding paper box structure plan with a embracing basin cover and a box bottom structure (see Figure 2) as an example, the straight plug-in folding paper basin structure plan in the original standard is replaced, and the plan of other structural forms is omitted. The examples and dimensional relationships of the plan of the lock bottom box bottom and the self-locking bottom box bottom structure are added (see 4.3 and 4.4). This standard was proposed and managed by the National Packaging Standardization Technical Committee (SAC/TC49). The drafting units of this standard are: Beijing Institute of Graphic Communication, Heshan Yatu Ren Printing Co., Ltd. The main drafters of this standard are: Xu Wencai, Guo Xinying, Jiang Dongsheng, Luo Xinglong. 1 Scope

3 Terms and definitions
The following terms and definitions apply to this standard. 3.1
Plug-in folding cartonsA box cover or bottom structure that is sealed by the friction between the cardboards after the tongue is inserted into the box body. 3.2
Bottom lock folding cartonsA box bottom structure formed by the intersection and interlocking of several faces at the bottom of the box. When the bottom plate is pressed against the side with hooks, the lock tongue is removed from the lock bottom plate to lock the box bottom structure. 3.3
Auto bottom lock foiding cartons
A box bottom structure formed by the intersection and interlocking of several faces at the bottom of the box. When the carton is formed, the bottom can be automatically locked.
