The Graveda Rosin Bags XL (70 mm × 160 mm) are heavy-duty nylon filter bags designed for professional rosin extraction. Their extra-large size allows for pressing higher volumes of cannabis flower, hash, or bubble hash without compromising filtration quality. Built from durable, heat-resistant food-grade nylon mesh, these bags ensure clean, solventless rosin production with exceptional strength and consistency.
Each bag is precisely stitched to prevent blowouts even under extreme pressure, making them ideal for both large-scale and home pressing setups. Graveda’s advanced mesh technology guarantees optimal oil flow, minimal contamination, and high terpene retention across every micron option.
Choosing the right micron size:
-
25–37 µm: For dry sift or bubble hash – finest filtration and cleanest rosin, less yield.
-
73–90 µm: For ice water hash or finer material – balanced yield and purity.
-
120–160 µm: For flower pressing – optimal flow with excellent purity.
-
190–220 µm: For large flowers or fresh-frozen material – maximum yield and minimal resistance.
Whether you’re pressing hash or flower, Graveda XL Rosin Bags provide professional-grade reliability and the durability needed for the highest-quality solventless extractions.
