FiltEdge's Plastic Bag Filter Housings Are Characterized By Three Key Features
- No more metal ions such as Fe, Ni, Cr, etc. to be precipitated, eliminating secondary contamination for you and guarding your process cleanliness.
- Plastic material is 1/3 lighter than stainless steel, you can spend 2 minutes to change the filter bag by yourself, especially light maintenance.
- Patented sealing design ensures 0 bypass and 0 leakage, providing you with a safe production line.
What Is FiltEdge's Plastic Bag Filter Housing?
FiltEdge’s plastic bag filter housings are mainly made of PP/PVDF, PP can cope with most of the low-pressure liquid filtration processes, which is a cost-effective filtration solution, while PVDF is mainly used in chip/semiconductor/pure water and other processes with particularly high requirements, which can ensure the purity of your process.
These 2 types of plastic filter housings are made of one-piece molding technology with no welding seams to reduce the risk of leakage, and the sturdy housing can better withstand the pressure, providing you with a stable filtration system. Our plastic bag filter housings use top-feed design, which can both provide you with even distribution of liquid and reduce pressure shock, as well as less liquid residue, allowing you to maintain the filter with cleaner operation.
Provide us with your working conditions, and we, as a plastic filter housing supplier, will customize the most suitable filter for you.
Types And Options of Plastic Bag Filter Housings
FiltEdge routinely offers three types of plastic bag filter housings that combine cost-effectiveness and high performance to provide you with the right plastic filter housing for your slurry chemistry.
PP Filter HousingsOne-piece molded PPH material, acid and alkali resistant, but suitable for low pressure and temperatures below 90°C.
PVDF Filter HousingsHas good acid resistance, will not precipitate metal ions, especially suitable for front-end coarse filtration in the chip and semiconductor industries.
PTFE Filter HousingThe main body is stainless steel lined with 2mm PTFE, which can provide you with a solid container that is not ruptured by the pressure impact, and can also be used to the excellent characteristics of PTFE material.

Application of Plastic Bag Filter Housings
Our plastic bag filter housings are widely used. We can provide you a cost-effective filtration solution.
In the semiconductor/microelectronics industry, e.g. the production of ultrapure water, acidic cleaning solutions, grinding slurries. Because of the chemical inertness of our PVDF plastic bag filter housings, there is no metal ion precipitation, which stabilizes your wafer productivity.
Our PPH plastic bag filter housings are resistant to strong acids and alkalis, and will not be corroded and perforated in applications such as galvanizing baths, pickling solutions, phosphating solutions, etc. This ensures your production safety and prolongs the life of your equipment.
In seawater, concentrated salt water, reverse osmosis front-end treatment, the biggest advantage of our plastic bag filter housing is that the natural characteristics of the material will not make it corroded by chlorine ions contained in the water like metal filters, which is the most cost-effective solution when you deal with seawater desalination.
FiltEdge’s plastic bag filter housings are fully sealed, providing absolute life safety protection in the production of nitric acid, chromic acid, organic solvents and other processes.
In the electrolyte and positive and negative slurry filtration, the most afraid of encountering copper and zinc ions, but our plastic bag filter housing can 100% guarantee that no metal ions will be precipitated, to avoid impurities from entering the inside of your battery, to improve the quality and safety of your battery.
FiltEdge’s PVDF plastic bag filter housings are wear-resistant, and PPH plastic filter housings have excellent corrosion resistance, which can both be used in leaching solutions, precious metal extraction solutions, in slurries rich in mineral particles and strong acids, and jointly used to improve the life of your equipment.

FiltEdge’s PP plastic bag filter housings are typically used at temperatures up to 70°C and PVDF plastic filter housings are used at temperatures up to 90°C. The temperature of the plastic filter housings increases as the structure of the plastic increases. As the temperature increases, the structure of the plastic will become unstable, resulting in a decrease in pressure capacity. Our engineers will provide you with the “pressure-temperature derating curve” according to the actual use temperature of your working conditions to ensure stable operation within a safe temperature.
Our PVDF plastic bag filter housings are not only made of pure PVDF, but also of PVDF, including the internal support blues. It does not contain fillers and colors. It can guarantee that it will not precipitate metal ions when filtering your liquids, as well as maintain extremely low TOC levels.
We don’t recommend you to do welding operation, because our plastic filter housing is molded in one piece, which will be more resistant to pressure. You can’t ensure the stability of the structure by welding by yourself and can’t guarantee the production safety. In case of shell damage, we suggest you directly replace the shell will be better.
There is no absolute “should” choose what material of plastic bag filter housing. It is mainly according to the chemical properties of the liquid, pressure, temperature and other conditions of your working conditions, to choose comprehensively. Comparison of the two materials, in the case of higher pressure and temperature, PVDF is the king of plastics, with high abrasion resistance, acid resistance, as well as the advantages of metal ions will not be precipitated, the most suitable for chips, optical coarse filtration, PP material is in the lower temperature, lower pressure conditions, to cope with a variety of acid and alkaline liquids. In most industrial scenarios, PP plastic filter housings can meet your use. If you can’t grasp what material of plastic filter housings you should use for your working conditions, you can contact us and we will help you analyze it.
We can provide you with EPDM (universal acid and alkali), Viton/FKM (strong acid, high temperature), and PTFE-coated O-rings (universal corrosion resistance). In order to ensure that your line does not leak, you will need to provide the chemical properties and temperature of your fluid to determine exactly which material to use.
