The matte white bag is our largest stock single use bag at 4" x 5" and offers optimal protection and functionality for packaging cannabis flowers, edibles or concentrates, larger pharmaceuticals and herbal supplements. An opaque finish alongside no tear notches and 5 mm seams deters small children from investigating the contents of your package. A high metallized barrier keeps odors airtight and free from smell, air and moisture. This functional, tamper-resistant bag is heat sealable using a standard hand sealer. Food safe.
