Application of Rosin Press Filter Bags :

The smaller 25 and 45 nylon micron Rosin Press Filter Bags are the most suited for squishing dry sift, bubble, dry ice, or other very fine material.
The 73 micron, 90 and 120 micron Rosin Press Filter Bags also have a specially designed seam used to keep fine particles out of your oil and prevent blowouts; they can be used for flower and lower grade types of hash. These are also the best choices for your flower and leftover trim.
The 160 and 190 micron Rosin Press Filter Bags can be used to squish out the absolute most from your flower or trim.
The 190, 220 and 240 micron Rosin Press Filter Bags are perfect for squishing out oils to be used for edibles, full spectrum oils for topicals and medicinal purposes.

Q1.Which micron size of the rosin bags should I use?
A: The below are our nylon Filter Bag recommendations for Flower, Hash.
1.Flower: 90u, 120u, 160u, 190u, 220u
2.Dry Sift: 25u, 45u, 73u, 90u
3.Bubble Hash: 25u, 45u
36-72 micron rosin press bags are best for dry sift, hash.
36 micron offers the highest level of filtration which results in the highest quality output.
72 micron offers a high level of filtration and better yields.
90-115 micron rosin press bags are best for flower.
90 micron offers the highest level of filtration which results in the highest quality output. 115 micron offers a high level of filtration and better yields.
Our suggestions:
1. If you are looking to maximize your yields and are not as concerned with allowing small amounts of plant material in your rosin, go with a higher micron size. 
2. If you are looking for the purest form of extract and value quality over quantity, go with a lower micron size. 
3. If you're looking for a balance of both, choose a micron screen that falls somewhere in the middle.

Q2. Can you reuse your rosin press bags?
Some persons may clean their rosin bags and give them another go, but remember that they've been stressed under 20,000 pounds of pressure. The pores of the bag have stretched and widened, particularly along the edges where the screen size most counts, and they'll be partly plugged with plant residue-even if you clean them well.
Can you reuse them? Yes, but they'll be a little less accurate and a little more prone to blowouts.

Q3.How many seam types for Rosin press filter bags? What is the difference each type?
A: Stitchless-Ultrasonic seaming:
This method employs frictional heat caused by high-frequency mechanical oscillations. This method employs frictional heat caused by high-frequency mechanical oscillations. This creates the heat required for welding and the material is plasticized. This type of seam should eliminate gaps for material to escape through and could be applied to any micron fabric.
Weakness: This seam was by far the weakest of all the seams. It did not hold up even under light pressure. Material easily escaped through the seams.
B: Stitchless-Thermal Bonding:
A process by which materials to be joined is heated causing the thermoplastic materials to melt. They are then compressed by applying pressure, which causes an intermingling of polymers. A seam is formed as the material cools and solidifies. This seam should create an impermeable seam. Disadvantages are seam stiffness and fiber degradation caused by excessive heat.
Weakness: This seam was stronger than ultrasonic seaming. But not as strong as sewing. We saw some promise in this method for hash processing, but due to the high heat used to make the seam, it can't be used on smaller micron fabrics.
C:Sewing:
The advantage of traditional sewing is a strength. The disadvantage is the stitch leaves gaps in the seam that can allow material to pass through the seam.
Conclusion: 

This seam was by far the strongest. The mesh fabric will tear before the seam blows out.

Q6. What are your terms of delivery?
A: EXW, FOB, CFR, CIF, DDU.

Q7. Can you produce according to the samples?
A: Yes, we can produce by your samples or technical drawings. We can build the molds and fixtures.

Q8. Do you test all your goods before delivery?
A: Yes, we have a 100% test before delivery
