Which magnets are used in the packaging industry?

In the packaging industry, we can often find the application of NdFeB powerful magnets. Magnets play an important role in packaging systems. Packaging manufacturers and designers, as well as marketing agencies, are unanimous in their preference for magnets when packaging their products.

The main function of the magnet in the packaging gift box is to seal the package.

What type of magnets are used in the package?

Common magnets in the packaging industry include single-sided magnets, disc magnets, square magnets, and bar magnets.

Among them, round magnets are the most common, and most of the exterior coatings are galvanized. The main reason is that the cost of galvanizing is low and the requirements for the working environment of magnets are not strict.

The magnetization direction of this NdFeB magnet is conventional magnetization through the thickness.

How to choose packing magnets?

About size: The size of packaging magnets is mostly thin. Common thickness sizes include 1mm, 1.2mm, 1.5mm, 2mm and other specifications. The specific size needs to be determined according to the type of each packaging product.

About performance: The performance requirements of packaging magnets are not high. Generally, low-performance grades of NdFeB are mainly strong magnets, and N35 grades can achieve strong suction.

Regarding the plating: what is the difference between a galvanized magnet or a nickel-plated magnet? Simply put, nickel plating is better than galvanized, but galvanized magnets are cheaper. Therefore, choose according to your own product needs. Nickel has a brighter appearance because it outperforms zinc in polishability. The treatment of the nickel surface also increases temperature resistance, coupled with the conductive properties of nickel itself.

About the price: Most customers pursue cost performance, as long as the suction meets the requirements, they usually choose cheap supply channels.

Regarding supplier capacity: the demand for packaging magnets is large, and the unit price is low, which requires suppliers to have sufficient production capacity to meet the supply.

What products are packaging magnets mostly used for?

Wine boxes, gift boxes, tea boxes, leather goods, clothing, whiteboard buttons, mobile phone boxes, bags, moon cake boxes and other products.

To sum up, the surface coating of packaging magnets should be galvanized. Under the premise of satisfying the suction force, the thinner the thickness, the better. Minimize cost
