SST-Porous® PE foam waterproof breathable vent seal liner（Typical application: packing for Inorganic fertilizer、 pesticides、organic fertilizer、hydrogen peroxide etc）
SST-Porous® PE foam vent seal liner, made by modified oleophobic ePTFE membrane and HPTE parts, welded together by ultrasonic or thermal melt. The completed component vent could equalize pressure imbalance to prevent container/bottle from deformation causing dangerous spills or costly returns.
For perforated container covers, gas will pass through the SST-Porous® PE foam breathable liners and escape through the hole in the container cover, while preventing liquids and particles from entering the package. Aluminum foil breathable liner prevent pressure buildup by continuously equalizing the differential pressure between the container’s internal and external.
For containers without holes, gas will pass through the SST-Porous® PE foam breathable liners and reach the area above the permeable membrane, and then be directed to the thread position of the container cover to escape, while preventing liquids and particles from entering the package. Aluminum foil breathable liner prevent pressure buildup by continuously equalizing the differential pressure between the container’s internal and external.
Technical FAQs:
1. Q: What are the main applications of breathable liner?
A: Mainly used in chemical, agricultural, food and other packaging fields.
2. Q: How to choose the breathable liner?
A: The selection of breathable plug depends on the type of packaging liquid, sealing form, installation size, breathable requirement and other items. Please consult the sales enginner details.
3. Q: What’s the characteristic of breathable liner?
A: Dustproof, Air permeable, leakproof.
4. Q: Will the container/bottle leak when using breather liner?
A: Generally no leaks after using breather plug. the main cause of leakage:
a. Bottle/container/Buket be inverted or turned over for a long time, resulting in leakage after airtight.
b. There is no hole on the outer cover, and the gas breaks through the breather membrane causing leakage
c. The liquid’s surface tension is too low, causing leakage.
5. Q: How about the acid and alkali resistance of the breather liner??
A: The recommended PH is 5 to 9 for conventional liner.
