North Mountain Supply wax melt single cube clamshell molds provide a simple, professional way to pour, package and present individual wax melts and other small creations. This pack includes 120 clamshells, giving you plenty of molds for production runs, sampler sets, seasonal offerings or craft fairs.
Each clamshell is made from PET plastic, which is:
-
BPA free
-
More environmentally friendly than PVC in many applications
-
The same type of plastic commonly used for soda bottles
PET offers good clarity so your colors and textures show through, and it is lightweight and easy to handle.
These molds are primarily designed for candle wax melts, but they can also be used for:
-
Chocolates and candies, when used with food safe processes and kept dedicated to food use
-
Small soaps or sample bars
-
Other DIY projects that benefit from a single cavity mold and integrated package
Each clamshell features:
-
Single cavity design that holds approximately 1 oz of product
-
Closed size of about 5.3 x 2.27 x 1 inches
-
A hinged lid that snaps closed, turning the mold into a ready to display retail style package
For best performance with wax, it is important to follow the recommended temperature guidelines:
-
Recommended pour temperature: 140 F to 150 F
-
Maximum pour temperature: 160 F
-
If you need to pour above 150 F for a specific formula, test with a single clamshell first to ensure the plastic does not deform
Staying within this range helps maintain the shape and clarity of the PET plastic and reduces the risk of warping or cracking.
The clamshells can be cleaned and reused in many cases, especially if you handle them carefully and respect the temperature limits. Be aware that repeated exposure to high temperatures may gradually lower the temperature threshold and increase the chance of cracking over time.
