For container lids with holes the gas will pass through SST-Porous®Aluminum Foil Venting Seal Liners and cover it through the container holes to escape while preventing liquids and particles from entering the packaging. SST-Porous® Aluminum Foil Venting Seal Liners prevents pressure build-up by continuously balancing the pressure difference between the interior of the container and the external environment.
For container lids without holes the gas will pass throughSST-Porous® Aluminum Foil Venting Seal Liners, reaches the area above the breathable film, and is then guided to the threaded position of the container cover to escape, while preventing liquids and particles from entering inside the package. SST-Porous® Aluminum Foil Venting Seal Liners prevents pressure build-up by continuously balancing the pressure difference between the interior of the container and the external environment.
Balance the pressure difference between the inside and outside of the liquid reservoir to prevent it from denting or swelling.
It can effectively prevent external dust and pollutants from entering the container and protect the stored liquid from contamination.
Can effectively prevent greasy liquids from passing through the breathable gasket, thereby reducing the risk of leakage
Technical Q&A
1) What are the main applications of Venting Seal Liners?
Venting Seal Liners are mainly used in chemical, agricultural, food and other packaging fields.
2) How to choose the correct Venting Seal Liners?
The selection of Venting Seal Liners is related to the type of packaging liquid, sealing form, installation size, breathability requirements and other items. For details, please consult: SST sales engineer.
3) What are the characteristics of Venting Seal Liners?
The main features are: dust-proof, leak-proof and breathable.
4) Using a Venting Seal Liners, will the barrel/bottle leak?
Generally, there will be no leakage after using Venting Seal Liners. The main reasons for leakage are:
1. The liquid in the bottle is left upside down or turned sideways for a long time, causing it to become airtight and leak.
2. There are no holes in the outer cover, and the gas will leak after breaking through the breathable membrane.
3. The surface tension of the liquid is too low, causing leakage.
5) What is the acid and alkali resistance of the Venting Seal Liners?
The recommended pH value for conventional Venting Seal Liners is between 5 and 9.

The application of Venting Seal Linerss in barreled hydrogen peroxide also has some advantages, here are a few examples:
In general, the application of Venting Seal Linerss in barreled hydrogen peroxide can balance gas pressure, prevent moisture and freshness, prevent pollutants from entering, and reduce the accumulation of harmful gases. These advantages can help maintain the purity and stability of hydrogen peroxide, extend the shelf life of the product, and ensure that the quality of hydrogen peroxide is not affected during storage and transportation.
