by Terp Proof
These PTFE squares are handy for packaging small amounts of extract for individual consumption. The material is highly chemical resistant, and non-permeable. This means that extracts stored in this material are less likely to bleed through than they would be if they were stored in parchment paper. The non-stick nature of PTFE also ensures that it's always easy to separate the extract from the material without it ripping or tearing.
