Directional Flow is a process that involves folding and shaping parchment paper into a form that siphons concentrate resin into a single area. This resin is typically then pressed with either heat or pressure to create rosin. Directional flow is sometimes also referred to as directional fold. Using parchment paper for directional flow is a simple process that might be more convenient than some of the other methods out there. You will need around an 8×12 sheet of parchment paper and then you fold it in half lengthwise, ensuring it is fairly even on all sides.
Once you make your folds while keeping all of the edges straight, you will get your bag and put it about an eighth of an inch up from the bottom. Then you fold the parchment paper over once again, making sure that all of the edges stay straight. Cutting off the top sheet is the next step about 4 inches up from the bottom. The bottom will typically be longer than the top. After that, you can do another cut at a 45-degree angle, taking the end off. Do this to both sides which will leave each edge looking the same. At this point, it should start to resemble what it’s supposed to look like.
When doing flower presses, it’s not advised to use a directional flow fold. This is because there isn’t enough rosin that comes out to make it even worth the effort. Rosin needs to be able to move around the plates to be able to come out of the front. Bubble hash can be used in directional folds very well. Directional flow systems can get pretty advanced which includes innovative technology to even create a quadruple directional flow system.
