Do Waterproof Plastic Cases Have A Magnetic Closure?

Do waterproof plastic cases have a magnetic closure? That's a question I get asked a lot as a supplier of waterproof plastic cases. In this blog, I'm gonna break down everything you need to know about magnetic closures in waterproof plastic cases.

First off, let's talk about what magnetic closures are. A magnetic closure is a type of fastening system that uses magnets to hold the case shut. It's a popular choice for a lot of products because it's easy to use and provides a good seal. You just snap the case shut, and the magnets do the rest.

Now, when it comes to waterproof plastic cases, magnetic closures can be a great option, but they also come with some pros and cons.

The Pros of Magnetic Closures in Waterproof Plastic Cases

One of the biggest advantages of magnetic closures is the convenience. They're super easy to open and close, which is great if you're in a hurry. For example, if you're out on a boat and need to quickly access your phone or other small items, a magnetic closure makes it a breeze. You don't have to fumble around with zippers or latches.

Another pro is the seal. When properly designed, a magnetic closure can create a tight seal that helps keep water out. This is crucial for a waterproof case, as even a small amount of water can damage the contents. Our Protective Waterproof Micro Case is a great example. It uses a high - quality magnetic closure that provides a reliable seal, protecting your small electronics from water damage.

Magnetic closures also tend to be more durable than some other types of closures. They don't have moving parts like zippers that can break or get stuck. As long as the magnets are strong enough, the closure will last for a long time.

The Cons of Magnetic Closures in Waterproof Plastic Cases

However, there are also some drawbacks to using magnetic closures in waterproof plastic cases. One of the main concerns is the strength of the magnetic field. If the magnetic field is too strong, it can interfere with electronic devices inside the case. For instance, if you're carrying a credit card or a magnetic stripe card in the case, the strong magnetic field could potentially demagnetize the card.

Another issue is the potential for the magnets to lose their strength over time. Exposure to heat, moisture, and other environmental factors can weaken the magnets, which may lead to a less secure closure. This could be a problem in a waterproof case, as a loose closure could allow water to seep in.

Making the Right Choice

When choosing a waterproof plastic case, you need to consider your specific needs. If you're carrying a lot of electronic devices or magnetic cards, you might want to opt for a case with a different type of closure. However, if convenience and a good seal are your top priorities, a magnetic closure could be the way to go.

It's also important to look at the quality of the case and the magnetic closure. Make sure the case is made from high - quality waterproof plastic and that the magnets are strong enough to hold the case shut.
