Rosineer 3" X 7" Premium Nylon Rosin Bags

Tired of frustrating blowouts and inconsistent yields? Achieve the purest solventless extracts possible with these premium rosin press bags from Rosineer. Engineered for reliability and purity, each bag is crafted from 100% food-grade, dye-free nylon, ensuring that nothing comes between you and your final product.

The standout feature is the robust double-stitching, which provides exceptional strength to withstand high pressure and heat, virtually eliminating the risk of blowouts. The bags are cleverly designed to be turned inside out, making them incredibly easy to fill without folded corners trapping precious material. For best results, pair them with a compatible Rosineer 3" X 5" Pre-Press Mold to create a uniform puck before pressing.

FAQs

What are these bags best used for?+

These bags are designed for the solventless extraction of rosin from herbal flowers, dry sift, and pollen. Their durable, food-grade construction makes them ideal for pressing high-quality, pure concentrates.

How do I choose the right micron size?+

The ideal micron size depends on your starting material. As a general rule: use lower microns (36µ, 72µ) for finer materials like dry sift or bubble hash, and higher microns (90µ, 120µ) for flower. This helps maximize yield while ensuring optimal filtration. For a deep dive, check out our guide on everything you need to know about micron bags.

Are these bags reusable?+

For the absolute best quality and purity, we recommend using a new bag for each press. While they are durable enough to be cleaned and reused, you may notice a decrease in yield and quality on subsequent presses.

Will these bags fit my rosin press?+

These 3" x 7" bags are suitable for any rosin press with plates that are at least 3 inches wide and 7 inches long. They are an excellent choice for many of the presses in the Rosineer lineup.

Should I use a pre-press mold with these bags?+

Absolutely. Using a pre-press mold helps compact your material into a dense, evenly-shaped puck. This improves efficiency and helps prevent blowouts by ensuring even pressure distribution during extraction. We recommend the Rosineer 3" x 5" mold for a perfect fit with these bags.
