The micron size tells us about the fineness of the bag. Lower the micron size of the bag, finer will be the holes and for higher micron number the holes diameter will be larger.

Micron bag is directly related to the quality of rosin extracted from the flowers or herbs. The flowers or the cannabis are inserted inside the micron to extract the rosin.

Low micron bags deliver high quality and lower yield while the higher micron size bad will provide more yield and low quality.

If you are looking for the highest quality of the rosin, you must go for the lowest micron bag. The most commonly used micron sizes are 15, 25, 37, 50, 75, 90, 120, 160, and 220.

The selection of the micron size depends on the source material being squished and the rosin quality required.

The rosin extracted from the flowers needs lower micron for high quality while if you are crushing the cannabis high micron bags provide better quality and yield.

Micron bags are generally made of nylon material and are available in a variety of sizes. In the post below we will discuss in detail which micron bag is best suited for different types of source material to get high quality rosin.

The Buying Guide

A wide range of micron bags are available in the market. These bags differ in size and quality of material. The following factor will make it easy for you to choose the right micron bag for your rosin press machines.

Micron Unit

The rosin press bags generally come in a range of 25-220 micron units. The lower micron bags are used for squishing the finer material while the coarse material is pressed with the higher micron size bags.

The quality and yield also with the micron number. The low micron bags deliver high quality and lower yield. The high micron bags deliver relatively low quality and higher yields.

The right quality and yield balance is achieved by selecting the right sized micron bags for extracting the rosin from the flowers. The micron unit of the filter bags therefore selected rightly to produce high quality rosin of reasonable yield.

Size Suitability

The rosin bags are produced in different sizes. These sizes are designed to suit the filter bags with the plate dimensions of the rosin press machines.

If a filter bag has dimensions of 2×5 inch then it will not be compatible with the plate size of 3 inch width. The size of the filter bag also guides us regarding the load capacity of the bag.

The bag should be filled as per permissible limit to avoid the rupturing of the bag. It must be noted while purchasing micron filter bags for the rosin press that it should be compatible with the press machine.

Material

The material of construction of the rosin press is of high importance. Generally the rosin filter bags are manufactured from the high quality nylon material.

The rosin bags made of silk or metal are also available in the market. The silk bags have lower durability while the metal ones don’t offer a good filter of the rosin.

The filter bags made of 100 % provide highest quality while the bags made from the nylon mixed material deliver relatively lower quality.

Another factor should be noted that the rosin filter bags should have food grade material. The food grade material maintains the taste and characteristics of the extracted rosin concentrate.

Solvent Resistance

The solvent resistance of the filter bags is very handy. The bags which show resistance to the solvent allow the filter bags to be cleaned with the alcohol or similar solvent.

The bags don’t rupture or damage during the solvent cleaning process. This cleaning process makes the bags available for reuse. If you are not interested in using the bag again then this factor is not important for you.

Temperature endurance

The rosin is extracted from the flowers by heating the flowers loaded in the micron filter bags. The temperature tolerance of each filter bag is usually mentioned on the packing of the bag.

Some high strength nylon filter bags are designed to withstand temperatures as high as 475 oF. Low temperature bearing filter bags are also manufactured.

The fine is squished under relatively low temperatures while the coarser material is squeezed under high temperature. A care must be taken that the filter bag should not be heated above the prescribed temperature limit of the bag.

Pressure Tolerance

Pressure is the key force that is applied on the flowers to extract rosin. Fine material requires low pressure for pressing while the coarser material will need heavier pressure for the extraction process.

A filter bag should be selected according to the pressure requirement. The filter bags are tested for pressure using them on a commercial scale.

The pressure tolerance of the micron filter should be read. A filter bag will blow out if more pressure is applied on it than the pressure which it can handle.

Dyes Free

Some of the filter bags are manufactured from the composite nylon material. This type of material has a mixture of chemical dyes. The dyes can leach into the rosin concentrate during the pressing process.

The dyes chemicals are harmful for the human, these chemicals also alter the taste of the rosin extracted with the dyes made from filter bags.

The material of construction of the filter bags is clearly mentioned on the specification sheet of the bag. The chosen nylon bag should be free of any type of dyes.

Low Blowouts

Blowout is another factor that is directly related to the strength of the material of the bag. A low strength filter bag will tear apart under pressure and rosin will stick to the plates of the press machine.

High quality nylon filter bags reduce the blowout and offer high durability. Some manufacturers of the micron filter bags even claim zero blowouts.

The blowout of the filter bags can be ascertained either by the practical or reading the customer’s reviews about the filter bag.

The Final Word

The rosin extracted from the flowers and herbs is very useful for a number of reasons. It is used in soaps, wax, soldering flux and varnishes. The rosin is an expensive item. The flowers are filled in the micron bags to extract rosin. The filter bags are made of high strength nylon material and can withstand high temperature and pressure during the pressing process.

We have reviewed and analyzed 10 top rated micron rosin bags. The discussed rosin bags are of different micron numbers. These bags are useful to get high quality and yield. This wide scope review is also useful for multiple users.

A comprehensive buying guide is also added at the end of the article. This guide will help you to eliminate the incompatible filter bags for your pressing process.

We are really hopeful that our article will be beneficial for you to understand the functions and features of the filter bags. We are also sure that you will buy a suitable rosin press bag after reading our review.

Frequently Asked Questions (FAQs)

The following frequently asked questions will also make it easier for you to understand the functionality of the rosin papers and their selection thereof.

What micron bag is best for rosin extraction?

The best micron bags for the extraction of rosin from the flowers are between the range of 37-220 microns. The smaller filter size removes more containment and produces high quality rosin. The larger micron filter bags deliver more than yield. Micron bags selected should provide a balance between quality and yield.

What are 160 micron bags used for?

160 micron filter bag is preferred for fresh flowers having humidity well over 65%. As the flowers dry and humidity reduces a smaller micron number filter bag is used. 120 micron bags are good for medium range humidity flowers. A 37 micron filter bag is good for squishing finer material.

Can a rosin bag be reused?

Yes, The solvent resistant filter bags can be cleaned to use again. The old filter bags are cleaned with the alcohol and then reused. But for subsequent use, the hole opening will be larger. The durability of older bags will also reduce and the chances of blowouts will increase.

How do you avoid blowouts and breaking of filter papers?

Most of the blowouts of the filter bags occur due to over filling. Care must be taken while loading the flowers into the filter bags. The extra stem should be removed from the flowers and it should be preheated a bit for smoothing extracting. The bags should not be filled to full capacity. As the filter bags are delicate, pressure should be applied gradually to avoid blowouts and breaking of the filter bags.
