China Neodymium And Ferrite Magnets Manufacturer & Supplier 
Have you already found that now many packaging products have been used in magnetic switches, such as high-end gift boxes, flip-top boxes, wine boxes, mooncake boxes, cosmetic boxes and display packaging, today we will introduce the magnets applied in it.
First of all, let me introduce you to why we use magnets? What are the advantages?
The magnet can be automatically closed and adsorbed to enhance the texture of the package. It can also be installed in a hidden way for a better appearance. Then, the structure design is flexible. Reusability is also strong.
The picture shows magnets for packaging - single sided neodymium pot magnets.
As for the magnets used, mainly rare earth neodymium and ceramic ferrite, rubber soft magnets, neodymium magnets are the more adopted solutions.
Below are some common magnet materials and sizes used in packaging systems, for reference only.
For gift box flap attachment, N35 thin round neodymium magnets, typical size 10mm x 1.5mm.
Used for gift box magnetic clasp, used with iron sheet, typical size is 15x5x2mm, block shape.
Some low-end gift boxes use ceramic ferrite, round typical size 12x2mm，12x3mm.
Mini carton adsorption structure will use thin flat rare earth neodymium magnets, typical size such as 5x1mm, 6x1mm.
Some packages that need to be combined with plastic parts will use ferrite or neodymium ring magnets with a center hole, typical size is 15x5x3mm. the hole is 5mm.
Some paper display packages will use flexible rubber magnets, strip or round.
As the packaging industry is more sensitive to price, the surface treatment is mainly galvanized, the choice of the size and thickness of the magnet needs to be considered to avoid excessive suction or suction, the final suction needs to be matched with the packaging material and thickness of the actual measurement, to ensure that the feel and durability.
