The type of rosin press paper you use really comes down to preference. Some people prefer using PTFE sheets because it's stronger and tears less easily under pressure. While others find the value of parchment paper unbeatable when it comes to price and performance. Our preferred rosin press paper is parchment, hands down. It's more affordable and way easier to find locally. We've heard some people say the cost of PTFE is not so bad because it can be reused, unlike parchment. In our experience using PTFE, we found the rosin being harder to collect in some areas. Maybe it was just the brand we tried but we went back to pressing our rosin with parchment paper. We do find PTFE great for displaying rosin since it can be more transparent than parchment. There are some concerns that the terpenes in rosin may act as a solvent to the silicone coating on parchment paper. For this reason, we don't store our oils in parchment paper. PTFE sheets are more resistant to solvents so we preferer it for long-term storage if glass jars are not an option.
PTFE rosin press sheets are a waterproof alternative to parchment paper. Sometimes when using parchment paper the oil can/will bleed through and end up on our rosin press plates. This rarely happens with PTFE sheets due to the strength of the PTFE material. In areas where we'd normally see parchment paper tear or get micro tears, PTFE tends to just stretch and become deformed. Even though the sheets are non-stick, PTFE seems to attract lint, dust, and hair like a magnet, no matter how clean the area is. We've also found PTFE to be harder to work with than parchment paper when it comes to collecting the oil. Some oils are stickier than others and can be a nightmare to remove from PTFE sheets.
Parchment paper is perfect for pressing rosin for personal use. It's very affordable and easily accessible. It seems to be the go-to rosin press paper for Extraction companies all over the United States at this time. Which is understandable because the cost of PTFE is four times that of parchment. This helps confirms our beliefs, that you just can't beat the value and performance in parchment paper. Parchment is not great under extreme pressure though. Anytime too much pressure is applied we run the risk of
getting micro tears in the parchment. Micro tears will only add to the problem of bleeding some people experience when using parchment paper. We know when we're using too much pressure because the material will start leaving a depressed (debossed) imprint on the parchment.
