Rosin Filter Bags FAQ
A rosin filter bag prevents trim and shake from getting mixed in with the rosin, making it easier to collect. The bags come in a 2×3 inch size, perfectly sized for the MyPress rosin press machine.
Our rosin bags are made of 100 percent nylon mesh. They’re high-quality, dye-free, and food-grade. Rosin filter bags are washable and highly durable. They’re also heat resistant up to 430 degrees Fahrenheit (220 degrees Celsius).
The technical answer to this question is yes, although we tend to frown on the practice. Once bags are used, the material has been stressed under six tons of pressure. Not only is it stretched, particularly around the edges, but the pores of the bag have widened. We know that some people clean their bags with ethanol before reusing them, but even this practice gives us pause. That’s because a used bag is likely to be partly plugged with plant residue, no matter how well it has been cleaned. We’re very proud of our rosin bags, particularly how strong they are. Still, it would be less than truthful to say that our bags retain their original strength after multiple uses. We recommend using new bags often to avoid blowouts.
You should use a rosin press bag when you’re pressing fine materials like sift, shake, or kief. Because these materials are so fine, pressing them in the rosin bag decreases the risk of them running with the oil during extraction. After all, the final product should be fresh rosin without any plant matter mixed in.
When it comes time to press using a rosin bag, we recommend pressing one to four grams at a time. You may need to adjust your plates to raise the top plate if you previously pressed flower, and you can do this by giving it a 1/4 to 1/2 turn in a counterclockwise direction. Set the temperature gauge to 190 degrees Fahrenheit for 120 seconds in order to increase your achievable yield.
