Why use a rosin bag for pressing rosin?

Using rosin press bags for rosin pressing helps create a much cleaner end product compared to using no extraction filters. Gutenberg’s rosin bag filters keep the unwanted plant material inside the bag while all your clean, precious rosin flows through outside of the bag. This helps keep your clean rosin separate from any plant material that could lower the quality of your rosin.  They offer many different micron sizes for the exact type of material you are pressing whether it is a high-quality flower or finer material like bubble hash.

It is important to keep in mind how to choose your correct micron size. The higher the micron size, the bigger the micron holes are around the rosin bag. This will produce a higher yield, but more plant material can flow through the rosin filter bag and into your end product. On the other hand, the smaller the micron size, the smaller the micron holes are around the rosin bag. This will produce a smaller yield, however, less plant material will flow through the bag making your end product much cleaner.  A good rule of thumb is for flower material, choose between 90u-220u. While for finer material like hash, choose a micron size between 15u-90u.  The most popular micron sizes for pressing flower are 90u, 120u, and 160u. The most popular micron sizes for pressing finer material are 25u and 37u.

How to Use a Rosin Bag

Using Gutenberg’s Dank Pressing Co.’s rosin press bags are pretty simple to use and very effective.

Here is how to use rosin bags step-by-step:

1. Pack your rosin bag tightly with the material you plan to press. If you are pressing flower, DO NOT grind up your flower. Just pack the buds in and gently remove any stems if there are any. You want your rosin bag to be packed like a tight brick of flower with no air gaps or holes.  Air gaps or pockets could reduce your yield and get rosin stuck inside the bag. At the same time, do not overpack the rosin bag because that can cause a blowout.  Start off by packing the bottom seam of the rosin bags are then slowly pack more from there. A good technique is to press down with your hand on the packed rosin bag so you can make sure it is packed tightly with no air gaps.

2. Leave about a half-inch of rosin bag at the top to fold over and close the rosin bag. If you have more than a half-inch of rosin bag left after packing, it is recommended to just cut it off so just a half-inch is left at the top.

3. Get a square sheet of parchment paper and fold it in half.  You can place your packed rosin bag right in the middle of the folded crease in the parchment paper and fold it over.

4. Gently place the folded parchment paper with the packed rosin bag inside in between your rosin press plates. Keep it right in the middle of the rosin press and then slowly apply more pressure to the rosin press so it is firmly holding your parchment paper and packed rosin bag in the correct position.

5. Then you can apply more pressure as you plan to do with the rosin press plated heated up to the temperature you want. Press for about 45 seconds to 3 minutes and watch all your rosin flow out of the bag!
