PE Ion Exchange Resin Square Bottom Valve Bag

Superior Material Performance
Polyethylene (PE) is a material with excellent chemical stability. It can resist various substances that ion exchange resins may come into contact with, such as acid-base solutions and organic solvents. This way, the packaging is not easily corroded or damaged, and it can protect the performance of the resin from being affected.

PE material itself has very low moisture permeability. When the packaging is well-sealed, it can effectively block moisture in the air. This prevents the resin from caking due to moisture, which is especially important when storing and transporting resin in humid environments.

PE Ion Exchange Resin Square Bottom Valve Bag is also quite strong, with a certain degree of flexibility and strength. During transportation, it is inevitable to encounter squeezing and collision, but it can withstand these, reducing the problem of resin leakage or contamination caused by packaging damage.

Adaptability of Packaging Design
In terms of sealing performance,PE Ion Exchange Resin Square Bottom Valve Bag is usually well-done. It generally adopts heat-sealing or zipper-type sealing designs, which can ensure that the packaging is tightly sealed. This prevents the resin from coming into contact with external air and impurities, helping to maintain the ion exchange capacity of the resin.

Some PE packaging will specifically add anti-static additives. This is to prevent static electricity generated when resin particles rub against each other, as static electricity tends to attract dust. At the same time, the dust-proof structure of the packaging can also block external impurities from entering.

If a block-bottom bag design is adopted, there are many advantages. The block-bottom structure makes the bottom flat and stable, which is convenient for stacking and storage, thus saving a lot of warehouse space. Moreover, when pouring the resin, it will be smoother, reducing the residue of resin in the bag.

Environmental Protection and Economy
PE material is a recyclable plastic, which meets current environmental protection requirements. Recycling is not only good for the environment but also can reduce the cost of handling packaging waste.

PE material itself is very light. Compared with metal or glass packaging, using it to package resin can reduce the weight during transportation, thereby reducing transportation costs. In addition, the production process of PE packaging is mature, so the cost of packaging is relatively low.

Divided by Capacity/Weight
Small packaging has common weight specifications of 5kg and 10kg. This kind of packaging is suitable for laboratory use, and it is also chosen when small equipment uses resin.

Standard packaging has common weight specifications of 25kg and 30kg, which is widely used in industrial production. Scenarios such as water treatment projects usually use this standard packaging.

Divided by Packaging Dimensions (taking 25kg block-bottom bag as an example)
The size of the bag body is approximately 50-60cm in length, 40-50cm in width, and 15-20cm in bottom width. It should be noted that the unfolded plane size should be calculated according to the structure of the block bottom, and the bottom is square or rectangular after forming.

The thickness of the PE film is usually between 15-50μm, and the specific thickness will be adjusted according to the weight that the packaging needs to bear. For heavy-duty packaging, the thickness can reach 50μm, which can enhance the tear resistance of the packaging.

Some packaging has special structural designs, such as adding linings. Aluminum foil layers are common linings, aiming to enhance moisture resistance. Others will add air holes to prevent the air pressure inside the packaging from rising, but at the same time, it must ensure that the sealing and dust-proof properties of the packaging are not affected.
