Who This Is For
- You are shifting to vertical bottle tech pressing because your flat bags keep shifting and causing blowouts.
- You are choosing 120-micron mesh because tighter screens are reducing your yield when processing dried flower.
- You are moving to double-stitched bags because your current seams fail whenever you increase the pressure.
What We Found
- We noticed these bags keep their shape much better during the pre-press than the cheap bulk options we used to carry.
- This 120 micron mesh is the sweet spot for flower because it keeps flow high without letting through much debris.
- Filling these with exactly 7 grams provides the perfect diameter for most three by five inch rosin press plates.
What Users Say
- Operators who switched to these say they stopped losing entire batches to the messy blowouts common with flat bags.
- Users pressing at home report that the vertical style helps them get more consistent yields across every single bag.
- People who pack these by hand say the stitching makes it easier to tuck the corners for a clean bottle tech prep.

FAQs
Bottle tech style involves packing the rosin bag so it stands vertically on the press plates, resembling a bottle or cylinder. This technique creates focused pressure, which can lead to higher yields and more efficient extraction, especially for flower. These bags are stitched specifically to support this vertical orientation and prevent blowouts.
These 2" x 4" bottle tech bags are designed to comfortably hold up to 7 grams of flower material for optimal results.
The bags are rated for temperatures up to 375°F. For flower rosin, we recommend starting at a lower temperature, around 180-220°F, and adjusting based on your material and desired consistency.
A 120-micron screen is an excellent all-around choice for pressing flower. It provides great filtration to keep plant material out of your rosin while allowing for a high flow rate and yield. For finer materials like kief or hash, you may want to explore lower micron options, such as our 75 micron or 37 micron bags.
For the highest quality and purity, we recommend using a new bag for each press. Reusing bags can introduce contaminants from previous presses and may compromise the bag's integrity, increasing the risk of a blowout.
These bags are compatible with any standard rosin press that has plates large enough to accommodate a 2" x 4" bag. The bottle tech style works particularly well with presses that deliver even, consistent pressure.
