Rosin Press Bags are used in the production of rosin products. The process of adding both heat and pressure to extract a concentrated version of your starting material is called "rosin". There are no dangerous and harmful solventless (like butane and propane) necessary in the production of rosin. Just heat and pressure. This makes rosin the cream of the crop when it comes to concentrates.

Gutenberg's Dank Pressing Co. crafts the best rosin press bags made of signature high quality Gutenberg nylon micron mesh. To begin, fill your rosin bag with starting material. Then place the filled rosin bag onto a rosin press. The press applies heat and pressure to the rosin bag to "squeeze" or "squish" the extract out while holding unwanted material in. Gutenberg's Dank Pressing Co.'s best rosin press bags are double-stitched to ensure a high durability so you can avoid blowouts. A "blowout" is when the bag ruptures during a press. They are extremely rare with Gutenberg's Dank Pressing Co. rosin press bags.

The space between the fine nylon mesh that makes a rosin press bag is measured in microns. A micron is one-millionth of a meter. For scale, a piece of your hair is just about 20 Micron. Gutenberg's Dank Pressing Co. offers the following micron size rosin press bags for sale: 15 Micron, 25 Micron, 37 Micron, 50 Micron, 75 Micron, 90 Micron, 120 Micron, 160 Micron, 190 Micron, and 220 Micron. The larger the micron size, the more material will pass through the fine nylon mesh. This means higher yields, but may also mean lower quality as some unwanted material may pass through. Smaller micron sizes (15 Micron - 75 Micron) are generally used for finer starting material such as hash. The higher micron sizes (37 Micron - 220 Micron) are best used for larger starting material such as flower.

How to Use

For hash, some users prefer to use 2-3 rosin press bags per press. The "Double Bag Tech" adds stability and durability to the rosin bag so the user can apply a high pressure without worry of a blowout. High pressure can mean high yields. Popular combinations include: 25 Micron inside a 25 Micron, 37 Micron inside a 90 Micron, 25 Micron inside a 160 Micron, and 25 Micron inside a 37 Micron. Which bag combination you use is entirely up to what works best for your process. We suggest using the smaller of the two micron sizes as the inside bag. Be sure to line the seams up as well!

For flower, users may choose to use Bottle Tech Style (BTS) Rosin Bags. These bags are stitched on opposing sides rather than the traditional side/bottom stitching. When pressing BTS, the rosin bag is packed and placed on the rosin press so it squishes vertically rather than the traditional horizontal squish. The end result is a circular rosin puck. Some users feel that pressing BTS allows for better pressure control, higher yields, and reproducible results.

And remember, pressed rosin press bags (called rosin chips or pucks) can be saved up and used to make fun edibles or tinctures. Even after being pressed, these rosin pucks may still contain small amounts of cannabinoids. With a large amount of pucks, you can make edibles just as strong as if you used regular flower.
