What is Bubble Hash Bag?

Bubble hash bags is mainly used to separate plants and resins, and filter out different grades of hash according to the needs.

Bubble hash bag is available for create full-melt or full-spectrum hash.
Bubble hash bag kit extracted and retained cannabinoids, flavonoids, terpenes and other substances without pollution.
The bubble bag filtration system can be equipped with multi-layer filtration to help you collect resin with a fineness of up to 25 microns.
All filters are made of edible-grade, high-toughness nylon mesh with double stitching technology to ensure adequate tension at the bottom of the bubble hash bag.
The bag is made of 600D polyester Oxford fabric. 
The surface of the fabric is environmentally friendly pressure coating, impervious to water, anti-delamination, longer service life.
The mouth of the bag is provided with an elastic band, which can easily adjust the size of the mouth of the bag to prevent water splashing when fully stirring.
At the same time, we have a rope hole nailed to the 32-50 gallon filter bag, which can be easily suspended for hash operation.

What is the main material of Bubble Hash bag?

The main materials of bubble hash bag are 600D PVC coated Oxford fabric and custom micron nylon mesh.

What is 600D Oxford fabric?

fabric of bubble hash bag

600D polyester fabric is the most widely used fabric in manufacturing bubble hash bags.

It is very cost-effective, stable performance, and can be quickly customized a variety of colors. 

Therefore, 600D Oxford fabric is more widely used than nylon.
So what are the characteristics of 600D Oxford fabric?
It has excellent wear resistance:
600D Oxford cloth is a durable, heavy-duty fabric with suitable thickness.
It has excellent tensile properties and wear resistance, and it can maintain stable performance even after 1000 high-strength cycles. 
Therefore, if used properly and kept properly, bubble hash bag can be reused for a long time.
Waterproof property of 600D Oxford fabric:
The water impermeability is mainly achieved by high pressure spraying PVC or PU coating.
In this way, we can ensure that Bubble hash bag can perfectly realize the extraction of hash and the separation of materials.
Anti-fading ability:
600D Oxford fabric is not easy to fade even if it is exposed to the sun. Bubble hash bag is still as good as new after many times of use, which is completely different from nylon, which is very easy to fade under the action of ultraviolet light.
In addition, the load-bearing capacity of the material is very important because Bubble bag will be filled with a mixture of ice and water during use. 
600D Oxford fabric itself is a heavy fabric, even if it is a strong external force, it is very difficult to tear it, which is one of the important reasons why we choose it.
In short, 600D Oxford fabric is the most ideal material for making Bubble hash bag.

What is Nylon mesh fabric?

mesh fabric for bubble hash bag

Monofilament nylon filament braided to form a custom aperture, high strength braided mesh, which is the nylon mesh used by bubble hash bag.
Nylon filter fabric has excellent chemical resistance and wear resistance, so it can be used for a variety of uses of bubble hash bag, whether it is chemical extraction or ice-water mixed extraction.
Compared with other filter materials, micron nylon filter mesh has the following advantages:
1. Anti-corrosion, anti-chemical reagent characteristics:
it can be very stable in a variety of chemical reagent environment to ensure the safety of the extracted material.
2. Temperature resistance:
It can be used stably in the temperature range of-40 ~ 130 °C, and the pore diameter is not deformed.
3. Toughness and wear resistance:
The dense fabric structure determines that it has a very strong tensile resistance, while the wear resistance of nylon wire itself ensures the friction resistance of nylon mesh fabric.
4. Nylon mesh material is stable and difficult to corrode, so after filtration, you only need to rinse clean.
5. Nylon mesh cloth is a cost-effective material choice because of its low price and outstanding performance.

What’s the Process of Hash with bubble hash bag?

process of bubble hash bag

First, stack the bubble hash bags sets in turn and put marijuana and ice in the bag.

Herb becomes brittle under the action of low temperature because it is soaked in ice, and the hair will fall off from the stems and leaves of the plant at this time.

Stir the ice-water mixture fully because the density of the trichomes is higher than that of water and will precipitate to the bottom of the bubble hash bag.

On the other hand, the leaves and the stems of plants will rise to the surface of the ice-water mixture under the buoyancy of water, thus achieving the effect of separation.

There are many materials essential to this process: ice, water, mixing sticks and, of course, various micron bubble hash bag.

The advantage of ice-water extraction is that it can harden the resin of herb and easily fall off from the plant body. At the same time, the whole process does not add any chemical solvent, so that herb can be extracted in a pure environment, thus achieving higher purity and perfect taste.


What the Function of different Micron grade Bubble Hash Bags?

function of bubble hash bag

Different micron grade of bubbls hash bag system make it possible to separate different quality resins, you can understand the level from different angles.
From the point of view of impurities:
Because of the large pore size, the main functions of the 220um and 190um bags are to filter impurities and extract resins.
The resins extracted by 160um bag generally contains impurities with relatively small particle size, so the quality is low.
The purity of resins extracted from other bags is better.
From the point of view of the quality of resins:
The quality of resins extracted from 120um, 90 μ m and 73 μ m was very good, and the performance of 90 μ m bag was the best.
The resins from the 45 micron bag can reach medium quality.
Resins filtered in 25 micron bags is usually immature and contains other impurities.

NOTE: The best extraction state is that 8 filter bags are complete.

If the bag is not complete, at least make sure there is at least one bag for each filter level.

You can refer to it as follows:

First filter level: 220 micron bag.

Second filter level: 160 micron bag.

Third filter level: 70 micron bag.

Fourth filter level: 45 micron bag
