[0025] Specifically, four right-angled triangular notches are formed on two sides of the top plate 3, and the four notches are symmetrically distributed with the center axis of the top plate 3 as a center, and the bottom plate 11 is in a trapezoidal shape. The first dustproof wing 2, the second dustproof wing 4, the third dustproof wing 10 and the fourth dustproof wing 12 are all in a trapezoidal shape. The surfaces of the top plate 3 and the bottom plate 11 are provided with hot melt glue. The material of the tear tape 14 is BOPP or PET. The white cardboard of the paper box body is composed of a face paper 15, a core paper 16 and a bottom paper 17.

[0026] In use, during warehouse transportation, the front panel 5, the left side plate 6, the right side plate 8, the bottom plate 11, the top plate 3 and the rear panel 7 can be unfolded in sequence to form a flat shape, so that the space occupancy can be greatly reduced. When it is necessary to package the product, the front panel 5, the left side plate 6, the right side plate 8, the bottom plate 11, the top plate 3 and the rear panel 7 can be folded in sequence by using an automatic packaging machine, so that a complete product packaging box can be packaged. When it is necessary to take out the content of the paper box body, the paper box body can be easily torn from the position of the tear tape 14, so that the internal product can be taken out. The paper box body can be torn from both sides. The top plate 3 and the bottom plate 11 are glued on the packaging machine by using hot melt glue, and the consumer can tear the paper box body from the tear tape 14 in use. The tear tape 14 can be opened from both sides, so as to replace the traditional zipper knife. The effective design of the two-way tearing position can solve the problem that the opening position of the traditional paper box body is not convenient to open.

[0027] The paper box body of the utility model uses white cardboard as raw material, the basis weight of the face paper 15 and the bottom paper 17 accounts for 10-25% of the basis weight of the original paper, and the basis weight of the core paper 16 accounts for 40-65% of the basis weight of the original paper. The production process of the white cardboard is as follows: pulping, deslagging, grinding, purification, molding, pressing, drying (steam temperature 170-210 degrees Celsius), gluing, coating, and finally soft matt, drying to obtain the white cardboard. The face paper 15 of the white cardboard contains 65±5% of coniferous wood bleached kraft pulp (NBKP), 15±5% of bleached kraft pulp (LBKP) and 20% of broke paper; the core paper (16) contains 50-60% of chemi-mechanical pulp and 40-50% of system circulation recycled pulp; and the bottom paper 17 contains 45±5% of coniferous wood bleached kraft pulp (NBKP), 25±5% of bleached kraft pulp (LBKP) and 30% of broke paper. The large amount of application of NBKP in the face paper 15 can improve the strength. The large amount of application of system circulation recycled pulp in the core paper can not only reduce the cost, but also has good directionality, thereby improving the easy tearing property of the paper box body.

[0028] The opening mode of the carton body of the present application is in the form of pasting tear-off adhesive tape 14. Compared with the traditional "zipper" mode, the easy-to-tear effect is greatly improved when the carton body is opened, and the problem of difficult tearing or quality of the carton body produced by the traditional "zipper" opening mode is avoided. The opening mode of the carton body of the present application is to use pasting tear-off adhesive tape 14 at the opening position, and the pasting is on the inner surface of the carton body. The carton body is not subjected to die cutting, which will not cause damage to the carton body and will not affect the appearance experience of the carton body. The above features ensure that the consumer will not have the problem of not being able to tear open when tearing open; and avoid the phenomenon of damage to the carton body and contamination of the product during transportation. The opening position of the carton body of the present application has a transverse depth design size of 8-12mm, a longitudinal depth design size of 6-10mm, which is 2-4mm larger than the two sizes of the traditional carton body, and the width of the tear-off adhesive tape 14 is 4-10mm, which is more convenient for hand tearing open.

[0029] The transverse depth and longitudinal depth of the carton body are compared and tested:

[0030]

[0031] According to the above data, when the transverse depth reaches 14mm and the longitudinal depth reaches 12mm, the carton body is very easy to enter dust. Therefore, the transverse depth of the carton body of the present application is set to 8-12mm, and the longitudinal depth is set to 6-10mm.

[0032] Working principle: During warehouse transportation, the front panel 5, left side panel 6, right side panel 8, bottom panel 11, top panel 3 and rear panel 7 can be unfolded in turn to form a flat shape, thereby greatly reducing the space occupancy rate; when the product needs to be packaged, only the front panel 5, left side panel 6, right side panel 8, bottom panel 11, top panel 3 and rear panel 7 need to be folded in turn using an automatic packaging machine, and a complete product packaging box can be packaged. When the contents of the carton body need to be taken out, the carton body can be easily torn open from the position of the tear-off adhesive tape 14, so that the internal product can be taken out, and the carton body can be torn open in both directions. By using hot melt adhesive to seal the top panel 3 and the bottom panel 11 on the packaging machine, the consumer can tear open the tear-off adhesive tape 14 when using it.
