Packaging Internal Pressure Resistance | Campden BRI

Summary

This video explains the process of internal pressure resistance testing for containers used in packing carbonated drinks, such as plastic and glass bottles. The test is performed by filling the container with water and applying hydraulic pressure, which is then measured. The pressure at which the container deforms or ruptures is recorded. Plastic containers typically rupture at 12 Bar, while glass containers, especially for sparkling wines and champagnes, exceed 16 Bar. This test helps detect weak points, defects, and troubleshoot issues in the supply chain, ensuring packaging integrity and safety.

Takeaways

• 😀 Internal pressure resistance testing is used to evaluate the ability of containers (glass or plastic) to withstand internal pressure, especially for carbonated drinks.
• 😀 The test is crucial for clients packing soft drinks, sparkling wines, and other carbonated beverages.
• 😀 The test method involves filling the container with water and hydraulically increasing pressure while monitoring the pressure gauge.
• 😀 For plastic containers, rupture typically occurs around 12 bar, with some distortion visible before the rupture point.
• 😀 Glass containers, especially for sparkling wines and champagnes, can withstand pressures exceeding 16 bar.
• 😀 Specifications for wine bottles typically require them to endure up to 16 bar of pressure or more.
• 😀 Glass containers may fracture in various ways, with some breaking down completely, highlighting the need to identify weak points or defects.
• 😀 Internal pressure resistance testing helps detect defects and weaknesses in containers, ensuring they meet necessary standards.
• 😀 The test also helps troubleshoot supply chain issues by pinpointing where problems or defects in containers may arise.
• 😀 Retailers use the test to verify packaging specifications from manufacturers and ensure the containers are safe and durable for carbonated drinks.

Q & A

What is internal pressure resistance testing used for?

Internal pressure resistance testing is used for containers, particularly glass and plastic ones, which are designed to pack carbonated drinks like soft drinks or sparkling wines. The test measures the pressure the container can withstand inside during use.

Who would typically use internal pressure resistance testing?

Clients that pack soft drinks or sparkling wines, as well as retailers who need to verify packaging specifications from manufacturers, would typically use this test.

How is the internal pressure resistance test conducted?

The test is performed by filling the container with water, which is then hydraulically pumped throughout the system. The pressure is recorded on a pressure gauge.

What happens to a plastic container during the internal pressure resistance test?

In the case of plastic containers, some distortion of the container is expected as the pressure increases. The rupture pressure for plastic containers is typically around 12 Bar.

What is the expected rupture pressure for glass containers during the test?

For glass containers, particularly those used for sparkling wines and champagnes, the rupture pressure usually exceeds 16 Bar. Most specifications for wine bottles are set to 16 Bar.

Why is it important to understand the rupture pressure of containers?

Understanding the rupture pressure is crucial as it ensures the container can withstand the internal pressures it will encounter during the packing and transportation of carbonated drinks. It also verifies that the container meets the required specifications.

How do glass containers behave under pressure during testing?

Glass containers can fracture in various ways when the pressure exceeds their tolerance. Some fractures may be dramatic, causing the entire bottle to break down. This can reveal weak points or defects in the glass.

Why is it important to identify weak points or defects in glass containers?

Identifying weak points or defects in glass containers is important because it can prevent failures during use. These defects can be detected during the internal pressure resistance test, which can help in troubleshooting and improving container quality.

How can internal pressure resistance testing help in the supply chain?

The test can help detect issues that may arise in the supply chain, such as defects or weakening in containers. This allows manufacturers or retailers to address these problems before they lead to product failures.

What role does internal pressure resistance testing play in ensuring packaging safety?

Internal pressure resistance testing ensures that containers can handle the internal pressure exerted by carbonated drinks without failing. It confirms that the packaging meets safety standards and performs as expected during storage and transportation.
