How To Wrap & Press Hash Without Rosin Bags
Rosin pressing traditionally relies on pre-made bags with stitched seams to contain hash during extraction. While convenient, these seams create problems that compromise both yield and purity. Stitching creates larger holes at attachment points, often exceeding 25 microns even when the mesh itself is finer. Resin gets trapped in seam crevices or leaks through stitch holes, and the structural integrity around stitched areas remains inconsistent.
