Description

Technical Field

[0001] The utility model mainly relates to the technical field of carton making, and in particular to a folding carton. Background Art

[0002] Cartons are the most widely used packaging products. They have various specifications and models according to different materials. They are usually used as packaging for goods or as outer protective layers for items. The volume of cartons varies with the size of the goods. Existing cartons usually have two bottom pieces that are fixed by tape. The overall force is not strong. When the tape is damp, it is very easy to lose its stickiness and it is difficult to fix. At the same time, tearing the tape will damage the carton, resulting in extremely limited reuse of the carton. Utility Model Content
