How To Select the Best Rosin Filter Bags?

Selecting the right rosin filter bag is crucial for achieving high-quality rosin. Here are some key factors to consider:

1. Material: Nylon is the most recommended material for rosin filter bags due to its heat resistance, durability, and ability to stretch under pressure.  It can stretch up to 40% under pressure, making it ideal for high-pressure extractions. Avoid materials like polyester and silk, which are prone to blowouts.

Other Materials: While nylon is preferred, other materials like polyester and silk are available but are less durable and more prone to blowouts

2. Mesh Size: The mesh size, measured in microns, determines  the size of the holes in the mesh, which affects the purity and yield of the rosin. Here are some general guidelines:

Flower/Trim: Use 90 to 160 microns for a balance of yield and quality.

Kief/Bubble Hash: Use 25 to 90 microns for the best quality.

3. Bag Size: Ensure the bag size matches your press plates. The filled bags should be completely covered by the plates during extraction, with a small gap between the bag and the plate edges.

Fit to Press Plates: Ensure the bag size matches your press plates. For example, a 2x4 inch bag is suitable for 3x5 inch plates, while a 3x6 inch bag fits 4x7 inch plates.

4. Filling and Usage: Turn the bags inside out so the seam is inside, fill them evenly without overstuffing, and fold the edge to prevent material from falling out. Pre-pressing your material into an even puck can also help.

5. Preparation and Packing

Turn Inside Out: Flip the bags inside out so the seams are on the inside, which helps prevent rosin from getting trapped in the seams.

Even Packing: Break down the plant material into small, even pieces and pack the bag evenly to avoid air pockets and ensure consistent pressure during extraction.

6. Quality and Durability

Double Stitching: Look for bags with double stitching for added strength and durability under high pressure.

Food Grade: Ensure the bags are made from food-grade materials to avoid contamination

By considering these factors, you can select the best rosin filter bags for your needs and achieve optimal results in your rosin extraction process.
