Description

Technical Field

[0001] The utility model relates to the technical field of packaging cartons, in particular to a moisture-proof and pressure-resistant environmentally friendly packaging carton. Background Art

[0002] The packaging box is mainly for the convenience of transportation, loading and unloading and warehousing. Generally, wooden boxes and corrugated solid wood pallets are used. Tin barrels or tin barrels are also used. Honeycomb paper boxes are made by punching, cutting and pasting honeycomb paperboard. Paper corner guards are pasted at the interface of paperboard for reinforcement. According to actual needs, it can be designed into different configurations such as integral type, combined type (detachable), integrated bottom bracket type, etc., which is more convenient for handling and loading and unloading.

[0003] However, most of the existing packaging cartons are used to package various items and are widely used in people's daily lives. However, during the storage of packaging cartons, due to differences in regional climate, such as high humidity in the south, the packaging cartons are prone to moisture and rot due to humidity. At the same time, the pressure resistance is poor, which leads to bending and damage when under pressure during use, causing trouble to the staff. For this reason, we propose a moisture-proof and pressure-resistant environmentally friendly packaging carton to solve the above problems. Utility Model Content
