Memahami Pentingnya Pengujian Kebocoran Kemasan Makanan

Food packaging leak testing ensures that products are safe, fresh, and uncontaminated by preventing air, moisture, or bacteria from entering packages. Testing also helps maintain the shelf life of the product and avoids recalls due to compromised packaging.

Pressure Decay Tests: A Reliable Approach for Package Integrity

Pressure decay tests measure the rate of pressure loss inside a sealed food package to detect potential leaks. The slower the pressure loss, the better the package integrity. Commonly used for flexible pouches, rigid containers, and bottles, the test provides insights into packaging material degradation. Example equipment: Cell Instruments LSST-01 Penguji Kekuatan Kebocoran dan Segel.

Vacuum Decay Tests: Ensuring Leak-Free Packaging

In vacuum decay tests, a vacuum is applied around a sealed package, and any vacuum loss indicates the presence of leaks. This method is effective for food packages like pouches and containers and ensures that external contaminants do not enter. Example equipment: Cell Instruments Penguji Kebocoran Mikro MLT-01.

Bubble Emission Tests: Visualizing Gas Leaks in Packaging

Bubble emission tests reveal leaks by submerging the package in water and applying pressure. If bubbles form, a leak is present. The test can be used across a variety of food packaging types, including bottles, cartons, and flexible packages. Example equipment: Cell Instruments LT-01, LT-02, and LT-03 Leak Testers.

Dye Penetration Tests: Detecting Liquid Leaks in Food Packaging

Dye penetration tests involve introducing a colored liquid to the packaging surface to visually identify any leaks. This test is particularly useful for flexible packaging and helps ensure the integrity of liquid or semi-liquid products. Example equipment: Cell Instruments LT series.

Dry Chamber Tests: For Liquid-Filled Products with Minimal Headspace

Dry chamber tests, also known as the ’empty chamber method,’ focus on packages containing liquid products with little to no air. This method is especially critical for products like juice boxes and milk cartons to ensure they are sealed tightly against leaks. Applicable equipment: Cell Instruments LT-01, LT-02, LT-03.

Helium Mass Spectrometry: Precision Testing for Ultra-Small Leaks

Helium mass spectrometry is one of the most sensitive leak detection methods. It is employed for high-precision applications where extremely small leaks need to be identified. It works well with various food packages and ensures no contaminants can enter or escape.
