What Is a Rosin Bag?

Rosin Micron Bags are typically a sown bag composed of NYLON mesh that filters out the plant material from the rosin/oil coming out when pressed with a Rosin Heat Press. Similar to how a coffee filter works, Rosin bags use the same concept. These bags come in various micron screen sizes depending on if you are pressing flowers or dry sift, bubble etc. They come in various sizes as well, that will depend on the rosin press you are using and the plate sizes it has equipt.

What Size Rosin Bags Should I Use?

For dry sift or bubble: Use 36 micron or 72 micron bags.

72 micron rosin bags will offer higher yields compared to 36 micron rosin bags, but the 36 micron bags will provide the highest quality product.

• 36 micron - Most filtration available, highest quality output rosin for use with dry sift or bubble.
• 72 micron - High level of filtration, increased yields over 36 micron when dry sift or bubble.

For trim, flower or shake: Use 115 micron or 90 micron bags.

You will get the highest yield from a 115 micron rosin bag over a 90 micron rosin bag, but a 90 micron bag will give you more filtration and slightly higher quality product.

• 90 micron - Higher level of filtration for use with flower, trim, and shake rosin pressing
• 115 micron - Ideal level of filtration and high yielding for use with flower, trim, and shake rosin pressing
