Key Points for Selecting Magnet Packaging

When selecting magnets for packaging applications, comprehensive consideration should be given to the characteristics of packaged products and actual requirements, focusing on four core dimensions: size, performance, price and supplier production capacity.

In terms of size, thin-type magnets are predominantly used for packaging, with common thickness specifications including 1 mm, 1.2 mm, 1.5 mm and 2 mm. Exact dimensions shall be determined flexibly according to the type of packaged goods.

In terms of performance, packaging scenarios do not impose stringent requirements on magnet performance. Low-grade sintered NdFeB magnets (such as N28 and N35) are sufficient to meet basic demands like sealing.

In terms of price, cost performance is the primary concern. As long as the pull force meets the standard, most customers prioritize suppliers offering better cost efficiency.

In terms of production capacity, magnets for packaging feature large demand yet low unit price. Suppliers must possess sufficient manufacturing capacity to ensure consistent and stable supply.

Main Application Scenarios of Magnets for Packaging

Magnets for packaging have an extensive scope of applications covering various high-end packaging and related products, with their core functions focusing on sealing and fixing.

Specifically, for gift boxes such as wine boxes, tea tins, mooncake boxes and general gift boxes, magnets are mainly used for closing, improving the tightness and premium texture of packaging.

They also serve for positioning and closure on leather goods, garments, luggage and mobile phone boxes to enhance user convenience.

In addition, packaging magnets are adopted for accessories such as whiteboard fasteners, further broadening their applicable scenarios.

Core Summary on the Application of Packaging Magnets

Overall, the core principle for applying packaging magnets is to minimize costs while meeting practical requirements.

Zinc plating is the preferred surface coating. It suits the operating environment of packaging applications and effectively cuts costs.

In terms of thickness, thin specifications should be prioritized on the premise of satisfactory pull force. This reduces raw material expenditure and better fits the design requirements of various slim packaging structures, striking a balance between practicality and cost efficiency.
