Heat Gun Safe Lip Balm Trays

Question:

I noticed that a heat gun was used in your video to smooth the lip balm tube tops. When I’ve used a heat gun on my small filling trays, it’s noticeably warped the plastic. Will a heat gun eventually warp your trays too, or is the plastic durable enough to withstand the heat?

Answer:

The HDPE Plastic that we use is very durable. Lip Balm Trays as well as most of our Soap Molds are made from this material. It withstands the repeated heat up and cool down of the soap making process as well as repeated use of a heat gun without warping, unlike injection molded trays.
