How to test? Open and close with one hand (tactile test), shake whilst upside down (lid-drop test); pay close attention to magnetic strength deterioration (caused by repeated opening and closing over time). For small-batch testing of magnets, produce a sample box first before placing an order.
How should they be positioned? Magnet placement (lid, sides): ensure alignment at the lid opening (engagement point); use dual magnets or corner magnets (for balance); ensure symmetrical positioning (misalignment will cause the lid to sit crookedly).
Magnets in packaging boxes are all about ‘getting the balance just right’: standardised by weight, symmetrical positioning, and one-handed opening — choose the right magnets, and opening the box is a bonus.
What structures do they pair with? Magnetic closure + flip-top lid, magnetic closure + six-sided lid (magnetic closure at the base of the lid): the polarity alignment of the magnets must be consistent during assembly.
How should the magnetic force be adjusted? Magnetic force (magnet specifications, quantity): the force should be moderate (allowing one-handed opening and closing); the thickness of the magnets (thin magnets) and their concealment (not exposed) are key details.
The ‘click’ of a magnetic box is a small moment of delight in the unboxing experience — but if the magnets are too small, they won’t hold; if they’re too large, the box is difficult to open; and if positioned incorrectly, the lid will sit crooked. This article clearly explains the key points of selecting magnets.
How to choose magnets? Magnets (neodymium, ferrite): neodymium offers strong magnetic force (for premium boxes), whilst ferrite is cheaper (for standard boxes); the dimensions of the magnets (diameter, thickness) should be matched to the weight of the box and the lid.
