Who This Is For
- You are refining your small batch extraction because using the wrong micron size leads to impurities in your oil.
- You are moving to Bottle-Tech packing because flat pressing leaves too much yield trapped in the corners of the bag.
What We Found
- This variety pack is the smartest way to learn how different micron sizes handle your specific plant material.
- We noticed these bags hold their shape better than cheap alternatives when using the Bottle-Tech packing method.
- The 160 micron bag is our go-to for fresh harvest, while the 90 micron keeps older, drier material much cleaner.
What Users Say
- Users say switching to these dedicated 3.5g bags finally stopped the messy blowouts they had with larger ones.
- Buyers who moved to Bottle-Tech packing report their yields are more consistent across every single press.
- People who press small batches tell us this kit solved their impurity issues by providing the right micron variety.

Micron Sizing Guide

As the micron number decreases, the mesh gets finer. This affects the diameter and surface area of the pressed puck. We recommend starting with 160 microns for fresh flower and moving to a smaller micron size, like 90, as the flower becomes drier. For material weighing 1 gram or less, a bag may not be necessary.

FAQs
The micron number refers to the size of the holes in the mesh. A lower number means smaller holes. 160µ is great for fresh, sticky flower to allow maximum flow, while 90µ or 37µ is better for drier material or kief to prevent contaminants from passing through, resulting in a purer final product.
A good rule of thumb is to start with a larger micron size (120µ-160µ) for fresher, more moist material and a smaller size (37µ-90µ) for older, drier material. Experimenting is key to finding what works best for your specific flower. For a complete overview, check out our NugSmasher Rosin Press Guide.
These bags are perfect for any press with plates around 2.5" x 2.5" or larger. They are the standard size for the NugSmasher Mini and also work well with the NugSmasher XP and Touch models for smaller, personal-sized presses.
While not required, using a pre-press mold like the NugSmasher 3.5g Pre-Press Mold can improve your yields. It helps compact your material into a dense puck, which prevents blowouts and ensures even pressure distribution during extraction.
NugSmasher rosin bags are designed for single use to guarantee the highest quality and purity in your final product. Reusing bags can introduce contaminants from previous presses and may lead to blowouts due to weakened seams.
