Rosin Industries 2.5" x 3.25" Nylon Screen Rosin Press Bags - 25u, 45u, 90u, 160u Questions & Answers

Which Material Should I Use?

Yields range significantly and depend largely on the quality of the materials used.

  • Trim: 3% - 8%
  • Shake: 8% - 15%
  • Flower: 15% - 30%
  • Dry Sift: 30% - 60%+
  • Ice Water Extractions: 30% - 70%+

Note: Adequate application of pressure is important to achieve optimal yields and these figures are based on averages tests. Results may vary and depend heavily on your material as well as the operator.

Which Micron Bag To Use?

Depending on your material, the proper micron bags are suggested but results will always vary.

For dry sift and ice water extractions use a 36 micron or 72-micron bag. 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.

For flower, trim, and shake, use a 115 micron or 90-micron bag. You will get the highest yield from a 115-micron rosin bag compared with a 90-micron rosin bag, but the 90-micron bags will give you more filtration and slightly higher quality product.

  • 36 micron - Most filtration available, highest quality output rosin for use with small and finer material.
  • 72 micron - High level of filtration, increased yields over 36 micron when pressing smaller and finer material.
  • 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.

What Temperature Is Ideal?

  • Lower temperatures (200°F- 300°F) = more flavor/terpenes, less yield, end material is more stable (shatter-like consistency).
  • Higher temperatures (300°F- 350°F) = less flavor/terpenes, more yield, end material is less stable (sap-like consistency).

How Much Pressure Should I Use?

There is no magic number for how much you need to press but most people use the formula of press pounds/plate surface area.

For example: A 10-ton press = 20,000 lbs. If you have a 3"x5" plate = 15 square inch. Hence, 20,000/15 = 1,333 PSI

Note: These numbers serve as a guide only. Results will always vary depending on temperature and material as well the press you choose. Refer to manufacturers recommendations for best results.

Not impressed
I have a 12 ton press with 4x7 plates that blows out the bags every time no matter what I do I'm not impressed with the quality of these bags at all as far as I'm concerned I wasted my money and materials
