Rosin Filter Bags Instructions

1.What is rosin filter bags?

Let us introduce rosin filter bags from Material, Micron, Dimensions, Application.

Material

The rosin filter bags are made of 100% Food grade nylon material.

The best material should be food-grade and boil resistant, allows for a bit of flex under pressure, and is pliable enough to easily work with.

Although there are nylon, silk, and metal bags available, only nylon material makes the grade. Silk doesn’t flex and is therefore more prone to blowouts, and metal screens can damage your plates. Nylon is the best material for pressing rosin.

Micron

The micron you are looking for depends on the material you are pressing. Sizes range from 15 to 120 microns. For pressed rosin, 120 microns is the largest size you would normally consider since hemp hairs are 120 microns in diameter (if not a little smaller). However, 160 and 220 micron bags are ideal for double bagging.

The main micron size:25, 37, 45, 73, 90, 120, 160, 190, 220 um

So which micron size should we use?

Flower : 75-120 microns and higher

Dry sift or Kief: 25-75 microns

Bubble Hash: 5-37 microns

115-micron – Flower and trim rosin at excellent yield with good quality

90-micron – Flower and trim rosin at great yield with great quality

72-micron – Flower and trim rosin at good yield with excellent quality

72-micron – Kief and bubble hash at excellent yield with good quality

36 micron – Flower at decent yield with the best possible quality

36-micron – Kief and bubble hash at good yield with excellent quality

Dimension

The hot size: 1.25"x3.25", 1.75"x5", 1.75"x8", 2"x3.5", 2"x6",2"x4.5",3''*6''

How big is your plate? How much original material would you like to press at a time? A bag full of rosin should fit nicely into the parameters of your plate and include about an inch of extra material at the top of the bag, which should be folded over to prevent the material from squeezing out of the top.

The tips of using rosin filter bags

Whether you are new to the rosin press, or want to improve your current quality and yield levels, this short guide will help you understand the importance of using rosin filter bags when pressing rosin and how to determine the right bag for your setup.

Rosin filter bags are used to hold hemp flowers, kief or bubble hashes when pressed between heated plates. The rosin bag provides a barrier for the rosin to separate from the raw material so that the final product is free of impurities.

Rosin filter bags are also used to achieve a more consistent density in the packaging of flowers, kief, or hashes, where rosin can flow freely from your material to parchment paper. By playing around with the rosin bag and its contents between your fingers, you can resolve any inconsistencies or small gaps in the material by eliminating the pockets between the flower pieces. This consistent packaging material will optimize your rosin yield.

Also, marijuana can be pressed without a rosin bag, but you may have tiny particles of plant matter in the rosin. Since the heat and pressure between the plates causes the hemp hairs and terpenes to liquefy, the bag ensures that only the good stuff is squeezed out and your ingredients stay inside, separated from the rosin.

While rosin filter bags all serve the same purpose, they are not "one size fits all" products. The main issues to consider when choosing the right bag are material, micron, and size.

2. How to pack rosin filter bags?

Stage 1: Prepare the rosin bag

(Basic information： The lower the micron size (i.e., 25u), the smaller the holes in the bag, allowing less plant material to pass through. The higher the micron (220u), the larger the hole in the bag, allowing more plant material to pass through. Generally, larger size microns (90u-220u) are used for flowers and smaller size microns (25u-90u) are used for dry sieving /keif or bubble hashes.）

Make sure the seam of the bag is on the inside of the bag. If the thread and seam are facing the outside of the bag, the bag needs to be flipped inside out so that the seam is on the inside.

This tends to increase the overall strength of the bag under pressure and also reduces the amount of rosin that gets stuck in the seams as it flows out of the bag.

The Jingda filter bag has been pre-flipped to save you time, so if you are already using our filter bag, you can skip this step. If not, please pick them up here.

One option to prepare the bag is to use a method called Bottle Tech, which folds the bottom corner of the bag inside the bag so the corners are concave. This allows the bag to stand upright in the press, rather than flat.

Stage 2: Prepare the Cannabis Flower Material

When packing the flowers by rosin filter bag, place the whole buds into the opening of the bag firstly, then push them toward the ultrasonic seal edge of the bag. You can push the bud down with your fingers or a narrow tool. We recommend using the whole bud instead of grinding your material, as the grinding process can actually agitate the trichome, and some of them can get stuck in the teeth of the grinder, reducing your overall THC content.

Keep packing until you've filled your bag. The bag should feel full, but does not matter or over packed. If you have an excess filter bag, use scissors to cut off the excess material so that the rosin does not absorb into the bag.

Once your bag is filled, we recommend the use of pre-pressing molds, different sizes of molds are suitable for a variety of hot plate and filter bag sizes. View Rosin Technology pre-press molds. This flattening technique improves production and prevents blowouts.

Once you've pre-pressed your bag and placed it between the parchment paper, you're ready to go.

Stage 3. Dry Sift and Ice Water/Bubble Hash

The method is slightly different if you use a dry sieve or ice water/bubble hash to pack your filter bag. You will need to use a spoon or funnel to insert this finer material. Slowly pour the dry sieve/hash into the bag with a spoon or funnel, making sure the material reaches the bottom of the bag and is evenly distributed throughout the bag.

Be very careful when pressing dry to sieve/hash and not overpack your bag. The bag should not feel very thick or completely full. Bags should not be more than ¼ inch thick, even before preloading. Once the material is thin and evenly spread throughout the bag, be sure to leave the ¼-½ inch filter bag empty. Fold back the excess material and "seal" the bag. For mass production, a neat little trick is to use a small amount of rosin to keep the "seal" in place. tIf the unused portion of the filter bag exceeds this length, use scissors to cut off the excess material.

Stage 4: Filling the rosin bag

Once you have your rosin material and rosin bag ready, it's time to bag it.

This stage of properly packing a rosin bag involves several steps, including filling the bag with a rosin funnel, reducing air pockets in the material, and pre-pressing.

If there are flowers in the bag, use your fingers to break up the clumps further so the material can form a solid mass inside the rosin bag.

Once the bag is full, use your fingers or a jammer-like tool to gently press the material into the bottom corners of the bag and evenly around all edges of the bag. You want to eliminate any gaps in the spacing and make sure the packaging is as consistent as possible.

Stage 5: Pre-press

After the bag is full and the material is slightly compressed, it's time to pre-press the material. Use such a precompression to quickly and thoroughly compress the material in the bag to increase the amount of rosin you can expect. Press Club has pre-pressed dies that can accommodate any size rosin bag.

Stage 6: Closing the rosin filter bag

The final step is to seal the top of the bag with a simple fold. Fold in the excess fabric at the top of the bag, this should be enough to keep the bag folded when it is between the boards.

Now that the bag is ready, grab the parchment paper and don't forget to preheat with very light pressure between the rosin pans before starting to flatten.

Our conclusion

As you can see, the process of making rosin can be quite technical, but with just a few simple steps, you can ensure an efficient press with maximum output every time. It might seem difficult at first, but that's what we're here for.

3. Can you reuse rosin bags after pressing?

Rosin press bags are reusable. They can be cleaned with alcohol and water to remove debris from the rosin press bags.

Be aware, however, that the seams of rosin press bags stretch once after use, which can have a huge impact on the pressure level during each extraction. You may also find that the extraction is not as pure as it once was.

So, ideally, you'd use a new rosin press bag every time you press rosin. This avoids blowouts and improves yield and quality.

4. Should I turn rosin bags inside out?

It's always a good idea to turn the rosin press bag inside out to keep the seams in. This puts the stitches under pressure and forcibly extracts any remaining oil instead of wasting the oil in the stitches.

5. Can you press rosin without a micron rosin press bag?

It is possible to emboss rosin without a rosin press bag, but there are disadvantages. The lack of filtering is the most notable drawback. Filter bags prevent large amounts of lipids from escaping from the source material during extraction. Without a micron rosin bag, more unwanted vegetable lipids would pass through with the rosin, potentially negatively affecting flavor.

Another disadvantage of pressing without micron rosin press bags is less control over platen PSI. Platen PSI measures the amount of pressure applied directly to the source material, not just the output of the printing press. Platen PSI depends on the area the material occupies between the plates. With a rosin press bag, this area is much more fixed than the area of the material without the bag, and therefore predictable, because without the bag to confine the material, the material will spread significantly under pressure. When pressing without a rosin press bag, the pressure is harder to dial in.

6. What are the best micron rosin bags?

The best rosin micron rosin press bags depend on the type of cannabis material you are pressing. A 15-37 micron rosin press bag is best for bubble hash, a 25-50 micron rosin press bag is best for dry sieving, and a 75-220 micron rosin bag is best for flower. Within these ranges, lower microns provide more thorough filtration, while higher microns result in higher rosin yields.

What exactly is a micron for rosin press bags?

First of all, we need to understand what exactly is a micron? A micron is a unit of length equivalent to one-thousandth of a millimeter. The micron specification of the rosin bag refers to the mesh size of the rosin bag. Use a small mesh rosin bag for a finer material, and a larger mesh bag for a coarser material.

Rosin press bag is one of the indispensable consumables for rosin press

The most common microns for rosin bags are 15, 25, 37, 50, 75, 90, 120, 160, 220.

7. Do I Have to Use Rosin Press Filter Bags When Pressing Rosin?

Using or not using filter bags is a very personal matter, depending on your own preferences.

If you don't mind getting a final product mixed with essential oils and botanical particles, you don't have to use a rosin press filter bag.

The taste of rosin pressed without a filter bag is more like regular smoking.

However, if you want to experience a better quality dab, we recommend you to use a mesh bag.

Also, you should be aware that you may experience a slight yield loss when pressing with filter bags, which means that ultimately you have to decide for yourself what is most important to you, quality or quantity.

Our suggestion is Rosin is best pressed using a rosin press filter bag to keep contaminants from entering the rosin, and also to better control the stress on the source material during extraction.

8. What is the best material of rosin press filter bags for rosin?

Nylon, metal, polyester and silk filter bags can be found in the market.

The best material for filter bags is nylon. It is heat resistant, durable and can stretch up to 40% under pressure.

Stainless steel mesh can easily scratch the platen surface and eventually damage them.

Polyester thread bags tend to burst due to heat shrinkage, while silk tends to burst because it doesn't stretch like nylon.

Regardless of micron width, the ideal material for your bag is 100% food grade nylon. Very dry flowers act like sponges. They crave moisture and quickly lose the quality rosin you've worked so hard to extract.

9. How do you make the highest quality rosin?

By using high quality rosin press filter bags and then hot pressing.

Excellent terpene preservation at 220°F or below, often yielding higher yields than cold-pressed methods.

We have had the best results when pressing flower or plant material at 210° - 220° F, providing a good balance between quality and yield.

10. How to prevent the rosin press filter bag from blowing out?

Making solvent-free rosin can be a relatively simple process, but there is still a lot that can go wrong.

One of the most common problems encountered by rosin producers is "blowout".

Burst occurs when your rosin press filter bags burst during the pressing process, allowing unwanted plant material to mix with the rosin, which can ultimately ruin your end result.

There are many factors that can cause a blowout to occur, most of which are due to poor technique.

So, if you suffer from blowouts on a regular basis, here’s everything you need to know in order to fix the problem once and for all.

Use high quality rosin press filter bags.

Doule stitched rosin bags

Another easy way to avoid blowouts is to use doulbe stitched rosin filter bags at the same time, or "dual bags."

Extra bags give you extra security without worrying about bursting, because if one bag does fail, the other will save the world.

Many commercial presses use double bagging as a precaution because even with perfect technology and top-of-the-line equipment, the chances of a blowout are slim.

Also, if you do try double Rosin bagging, make sure the seams of each bag are on opposite sides of each other, this should guarantee maximum structural integrity.

Do not overfill the rosin press filter bag.

Bags that are overfilled can easily burst or slip.

Leave 1/2 inch space at the top to fold and close the rosin press bag.

Fill the rosin bag evenly.

A uniformly filled rosin press bag will apply consistent pressure to the entire surface area of the bag.

An uneven bag may experience more pressure in one area than another, causing it to burst.

Rosin bags replacement.

Fold a piece of parchment in half and secure it to the top and bottom panels with magnets.

Place the rosin filter bag in the center.

Remove the top magnet so the top of the dryer sheet folds down onto the ba

Which micron rosin press filter bags is best for rosin flower?

The recommended micron size for floral rosin is 115u to 120u. The ideal range is 90u to 120u.

The tricolor head is the most cannabinoid-rich part of the cannabis plant and is approximately 120 microns in diameter.

So it makes sense to filter them out using a micron-sized filter so their cannabinoids can be liquefied and extracted, leaving the plant material behind.

The 90 micron bags are also great for fresh flowers. You get better filtration and higher quality, but with that comes lower yield.

Most people find that 115u is the sweet spot for the best balance of yield and quality. We agree with that.

If you want the absolute highest quality and don't mind sacrificing yield, choose a 72 micron bag.

We've seen some sites recommend bags with a micron of 160, 200 or even higher.

They say you can then repress the extract through 25u or 36u rosin press filter bags to remove any impurities and get a super high quality rosin.

Which size rosin micron bags is best for rosin kief?

Because the bags material flows more easily, we recommend using the finer 36 micron nylon mesh for bubble hash/kief.

If you are looking for an extra quality product. The finer mesh also helps keep dust particles in the bag.

72 micron rosin press filter bags are also an acceptable choice for kief and bubble hash.

What is the optimal micron for Hash Rosin (Bubble Hash, Dry Ice Hash, Dry Sifted Hash)?

We suggest rosin filter bags micron size for floral rosin is 25u or 36u.

The ideal range is between 25u and 90u.

Because each type of hash has been slightly suppressed, you can use a thinner bag.

As with kief, we generally suggest starting with 36u and then increasing or decreasing the size depending on the results.

If you are not satisfied with the yield, please increase the size. If you find the quality is too low, please reduce the micron size.

Summary: Which micron size should I use ?

For flowers rosin: begin with 115u or 120u (ideal range: 90micron-120micron rosin press filter bags)

For kief rosin: begin with 36u or 72u (ideal range: 36micron-72micron rosin press filter bags)

For hash rosin: begin with 25u or 36u (ideal range: 25micron-36micron rosin press filter bags)
