Magnetic Package Closures
Innovative and Cost-Effective Magnetic Packaging Closures
Overview
Magnetic closure packaging from Adams Magnetic Products offers a unique blend of creative design, ease of use, and robust performance.
These packaging magnets are ideal for various applications, providing easy-to-open devices and strong repeat closure technologies.
Adams ensures top quality and value, assisting customers at every stage of the design process.
Popular solutions include flexible magnets for versatile designs, neodymium magnets with steel strike plates for hidden closures, and powerful magnet-to-magnet closures for the strongest “snap” effect.
Design Considerations
In addition to your physical and design aesthetic requirements, we’ll want to know the magnetic closure retention force in order to determine whether two magnets or one magnet with a steel disc or strike plate should be used.
The air gap (the space between the magnets or steel receptive piece) caused by the material in which you encase the magnet will affect pull force and performance. We recommend testing several samples before settling on the best magnet closure for your design.
Strong
Flexible magnet material can be bent and flexed without affecting its performance.
Adams can cut, score, or die-cut to match any shape requirements.
This product is not recommended for hidden magnetic closure applications, as its strength does not reach through barriers well, and it needs to be applied directly to a matching flexible magnet or to steel.
Stronger
Neodymium magnets matched with steel strike plates offer a stronger packaging magnet alternative to flexible magnets and can be used for many hidden closure applications.
Ask us about balancing the size of the magnet to the strike plate.
Often, it’s best to have a larger diameter strike plate than a magnet. Both our magnets and our strike plates can be supplied with adhesive on one side, saving you time and effort.
Strongest
Looking for a real “snap!” closure? Magnet-to-magnet closures marrying neodymium magnets will give you the strongest closure solution, whether the magnets are hidden or exposed.
For the most strength in a small package, try our TabMAG® magnets. These compact magnetic discs with adhesive backing and a new, easy pull tab are the strongest magnetic package closure products on the market.
More About Packaging Enclosures
Whether clearly visible or completely hidden from view, these attractive magnets offer near limitless potential for creating convenient, durable, and reusable high-end packaging that carries a company’s brand far beyond the initial product purchase.To learn more about magnetic closures, please read our blog post Magnets for Packaging Closures, or contact us to discuss your project today.
Magnet Applications
Let Adams help choose the magnet to best suit your specific application requirements.
We have experience designing magnetic closures around the effect of environmental conditions, temperature, shock, vibration, corrosion resistance, magnetic stability, manufacturability, form factor (and more!) related to the use of magnets, and can help optimize the performance of your application.
Hall Effect Sensors
Magnetic Hall Effect Sensors are popular for their versatility in sensing position, velocity, and/or direction. Offering non-contact and wear-free operation, they are low maintenance, essentially a “set it and forget it” operation.
Motors
Magnets and assemblies from Adams Magnetic Products can be found in many types of motors, generators, and actuators.
Guitar Pickups
Adams Magnetic Products supports the music industry every day by supplying high-quality alnico and ceramic magnets for every style of pickup made. Select from our stock sizes, or we can produce to your exact specifications.
