Rosin Bag - 2.25" x 4.25"


A 2" x 4" rosin bag on The Rosin Machine are great for sampling material before committing to a full press. Press up-to 8 Samples of 7 grams of flower at one time, monitoring the stability, speed, and color the oil comes off at a specific temperature. 


Bag to Puck

Access Rosin designs their bags to fit an exact square inch. All current bags +Flap are measured .25" larger ID dimensions to fit the height of the puck. 

For example, the 2.25" x 4.25" Fits a 2" x 4" (8"sq.) puck. 

Pressure to bag 

Adequate rosin presses provide pressure being to the bag area. Don't get this confused between the rosin press pressure to surface area. The pressure is what separates the oil from the plant material. The less pressure the slower the oil moves. 

Puck to Plate

The closer to the edge the puck is to the heat plate edge upon squish, then the faster the oil releases from the bag and off the heating plate. 



Nylon Silk Screen Rosin Bag with additional Flap. Access Rosin reinvented the rosin bag by add a flap to maximize bag capacity and not use the bag itself to close the opening. Instead the flapped bag allows the consumer to maximize every press by filling the bag 100% while filtering all 4 sides of the puck. 

The difference + flap design makes against traditional rectangle bags is zero of the bag is used as a fold to close the opening, which in fact maximizes full capacity.

Let the bag be the bag, and the flap secure the filter.
