Description

Technical Field

[0001] The utility model relates to the technical field of PC boards, in particular to a PC composite luggage board. Background Art

[0002] Usually, in order to enhance the strength of luggage, a PC sheet is installed on the back of the luggage (i.e. the side where the pull rod assembly is installed) and the bottom of the luggage (i.e. the side where the roller assembly is installed) to improve the load-bearing capacity of the luggage. However, conventional PC sheets have low chemical corrosion resistance. As various items are placed in luggage according to their own needs, if acidic or alkaline liquids leak in the luggage, such as cosmetics, it will cause corrosion damage to the PC sheet, thereby reducing the strength of the PC sheet; in addition, conventional PC sheets are prone to accumulate static electricity. After being installed in luggage, it will make the surface of the luggage more easily absorb dust and dirt. Utility Model Content
