Once your fully customized melt and pour soap has cooled, it’s time to package it up! It is important to package the melt and pour glycerin soaps appropriately to avoid contact with moisture.

While there is a classification of melt and pour soap base called “Low Sweat” specifically designed to counter this issue, all other soap bases should be considered “High Sweat”. The glycerin in melt and pour soaps attract humidity and as such have a propensity to “sweat”. This can alter the design of your bar and leave undesirable soap spots on surfaces in contact with unwrapped soap. For this reason, an airtight plastic packing is recommended.

Shrink Wrap Bags

Found in craft stores or in the gift aisle of big box stores, these are plastic bags with tiny holes. When heat is applied, these holes allow air to leave the bag and shrink it to the size of the object inside. This packaging option can create a professional look for your soap.

If you choose to use this method, be aware that the heat from shrink wrapping can alter the shape of the soap. To help prevent this, keep the heat source as far away from the soap and packaging as possible when heating. Move the heat source back quickly in order to avoid overheating any one area of the soap bar.

Cello Bags

Also called poly bags, these small plastic bags can be found in craft or catering stores as they are often used to package food or wedding favors. These have a neat look to them, especially when the appropriate label is applied. However, depending on the ambient temperature and size of the bag, the soap inside can smear the bag. It is, therefore, a good idea to choose a bag that just fits the size of the soap with little wiggle room.

Plastic Wrap

One common packaging option - which you may already have in your kitchen - is plastic or saran wrap. Place the soap bar face down on a sheet of plastic wrap and tightly pull the wrap around to the other side until the bottom of the soap is covered. Add a label where the plastic wrap meets to hide the folds.

Paper Packaging

Melt and pour soap made with a "low sweat" base can be wrapped decoratively in paper or cardboard found in craft stores. Alternatively, neatly cut up brown paper bags or old newspaper to use for packaging.

Once packaged in the appropriate material, soap should be stored in an airtight container such as tupperware for long-term storage. Also note, it is best to store scented soaps separate from one another as the fragrances can intermingle.
