[ 40 Pack ] 2x4.5 Inch 90 Micron Pressing Filter Bags - Nylon Mesh Screen Made

About 90 Micron Bags: The 90-micron bags are made of premium nylon mesh screens. Each package contains 40 pieces of stitched nylon extraction bags. The PETP sheets are included for loading the compressed flower easily. The 90-micron filter bags are suitable for a heat press machine with a larger-than 3x3" heated platen. 2x4.5" sized filter bags are recommended to pair it with a 2x4 inches rectangular pre press mold or a cylinder/round pre-press mold (30mm in diameter). 2x4.5" sized bags allow cutting into the half after pairing it with a 30mm cylinder/round prepress mold for pressing twice. Precaution for Use: It is not recommended to pair it with a small leverage heat press machine or less than 2 tons pressure of force. A pre press mold is suggested in order to fill the entire bag as much as possible and load more materials for reducing blowout and increase the yield. While extracting the fine materials with 90 micron bags, 30mm stainless steel cylinder prepress or 2x4 pre press is the best choice, but both of them need a vise clamp to be assisted. Remove excess stems from flowers, use less material in the bag, apply the pressure slowly, pre-heat the material first to get it melty before you start to apply pressure for reducing blowouts.
