There are a lot of different types of magnets available in our industry. Flexible fridge magnets can range in thickness and holding power, there are various options for the finish and the option of being waterproof. All play a factor in the cost of the magnets.
The thicker the magnet, the stronger the holding power. The most common fridge magnet materials are 11 mil, 15 mil and 20 mil thick. The 11 mil magnets (business card weight approx.) won’t always stay put and can slide down the fridge, they do not have enough holding power to hold up a piece of paper and have a tendency to curl up on the edges. 15 mil and 20 mil magnets cost a bit more but will hold up paper on the fridge, lay flat and the magnet will stay in place.
Now for the finish options and what makes magnets waterproof. The printable surface is gloss paper or matte vinyl. A varnish or UV coating can be applied after printing as well as a laminate or in some cases, nothing is done after printing. The extra coating and laminate can provide protection from scuffs, marks, fingerprints and enhance the colours of your artwork. The paper option is not waterproof as vinyl is. Vinyl is normally not laminated or need an extra coating as the surface is much more durable.
It is a good idea to see samples of previous work to check out the print quality, thickness and finish before you order. Not all suppliers will make all the different types of magnets either. Your budget, the application and reason for the magnet purchase will help choose which type of magnet will work for you and which will represent your brand or event the best.
What do we produce… Our standard fridge magnets are 28 mil thick (20 mil magnet material with a paper print and gloss laminate). We do offer the 15 mil version for our larger size fridge magnets. A large magnet covers more surface which makes for a stronger hold. The waterproof, outdoor and vehicle magnets we produce are 34 mil thick (30 mil magnet material with a vinyl print).
