The Premium Nylon Filter Bags from Dulytek, available in various sizes, are high-quality pouches designed for rosin extraction and concentrate pressing. Crafted from durable, dye-free FDA-approved food-grade nylon, these 2" × 4" filter bags resist boiling and solvents while offering superior strength and flexibility. Precision-folded seam stitching dramatically reduces the risk of blowouts during pressing, giving you confidence and consistency with every press. Each pack comes with either 20 single-mesh bags in your choice of 25, 100, or 160 micron screens or a mixed trial pack with multiple sizes, plus a free flexible packing card for effortless loading and handling. Just like the Parchment Paper Pre-Cut Extra Durable and Unbleached Parchment Paper, the Premium Nylon Filter Bags from Dulytek are ideal for flower, sift, or hash. Dependable performance and thoughtful design make them a standout accessory for extract enthusiasts.
