How to choose the right venting solution for your chemical packaging: A guide by PorVent?

Chemicals are essential for various industries and applications, but they also pose significant challenges for packaging. Chemicals can be aggressive, volatile, corrosive, or sensitive to environmental factors such as temperature, altitude, humidity, and pressure. These factors can affect the integrity and performance of the packaging, leading to leakage, deformation, contamination, or explosion. Therefore, it is crucial to choose the right venting solution for your chemical packaging to ensure safety and quality.

What is venting and why is it important for chemical packaging?

Venting is the process of allowing air to flow in and out of a container, while preventing leakage and ingress of contaminants such as water and dust. Venting is important for chemical packaging because it helps:

• Constantly equalize the pressure inside and outside the container, preventing the build-up of excessive pressure or vacuum that can cause the container to bulge or collapse.
• Prevent leakage of the chemical product due to packaging failure - avoiding wastage, environmental damage, and potential hazards.
• Prevent the deformation of the container due to pressure changes, maintaining the aesthetic and functional quality of the packaging.
• Make the container breathable, allowing the chemical product to release gases or vapors that can affect its stability or efficacy.
• Provide ingress protection, preventing the contamination of the chemical product by water and dust that can compromise its quality or safety.

What are the types of venting solutions available for chemical packaging?

There are various types of venting solutions available for chemical packaging, depending on the size, shape, material, and application of the container. They have a venting membrane that allows air to pass through, while blocking water and dust. They can be used for aggressive chemicals, nutrition products, and pharma and care products. Some of the common types are:

• Vented Inner Plugs: These are plugs that fit into the neck of the bottle or can, creating a seal between the cap and the container. They are suitable for containers ranging from 1 liter to 10 liters.

• Vented Induction Liners: These are liners that are induction sealed on the neck of the bottle, creating a tamper-evident seal that prevents leakage and contamination. They are suitable for containers ranging from 100 ml to 1 liter.

• Vented Push fit Plugs: These are plugs that fit into a groove in the cap of the jerrycan/drum/barrel, creating a seal between the cap and the container. They are suitable for containers ranging from 10 liters to 100 liters.

• Vented Caps: These are caps that have a venting membrane directly welded on them. They are suitable for various types and sizes of containers.

• Vented Bungs: These are bungs that fit into an opening on the drum, creating a seal between the drum and the bung. They are suitable for 210 liters drums.

How to choose the right venting solution for your chemical packaging?

Choosing the right venting solution for your chemical packaging depends on several factors, such as:

• The size and dimensions of the packaging: You need to select a venting solution that fits the packaging properly, ensuring a tight and secure seal. You also need to consider the available space and clearance for the venting solution, avoiding any interference with the cap of the packaging.
• The material that has been packaged to check product compatibility: You need to select a venting solution that is compatible with the product, ensuring that there is no adverse reaction or degradation of the venting membrane or the packaging material. You also need to consider the type and properties of the chemical product, such as whether it is water-based or oil-based to select the right membrane.
• The required airflow: You need to select a venting solution that provides adequate airflow for the chemical product, ensuring that the pressure is constantly equalized and the product is breathable. You also need to consider the environmental conditions, such as the temperature, humidity, and altitude, and how they affect the pressure and the gas generation of the chemical product.
• The ease of application: You need to select a venting solution that is easy to apply and integrate with the packaging, ensuring that there is no complexity involved. You also need to consider the availability and accessibility of the venting solution.
