Snack Food Packaging Barrier Test - ASTM F392 Flex Tester

Snack food packaging must protect products from oxygen, moisture, and physical damage throughout storage and transportation. Performing a snack food packaging barrier test is essential to ensure barrier integrity, especially for flexible packaging materials.

Why the Snack Food Packaging Barrier Test Matters

Barrier testing is critical in the snack food industry. Snacks like chips, nuts, and crackers are highly sensitive to oxygen and moisture. Without a proper barrier, oxidation and moisture absorption can lead to off-flavors, staleness, or microbial spoilage.

De snack food packaging barrier test helps manufacturers evaluate:

Seal integrity and material resistance to mechanical stress.
Barrier performance after flexing and transportation simulation.
Shelf life impact due to real-world handling conditions.

These tests not only help meet quality standards but also prevent product recalls and brand damage.

Flex Durability Testing with Gelbo Flex Tester and ASTM F392

The Role of the Gelbo Flex Tester

De gelbo flex testare simulates the twisting and compressive forces packaging materials endure during handling and shipping. It introduces controlled mechanical stress to packaging films and laminates to identify weak points and failure modes.

Cell Instruments’ Gelbo Flex Tester is specifically designed for precision and repeatability, offering advanced features for customized testing, ideal for R&D and QC departments in food packaging.

Understanding ASTM F392

De ASTM F392 standard outlines the test method for flex durability of flexible barrier materials using a gelbo flex tester. It ensures consistency in testing across laboratories and industries.

Key aspects include:

Defined flexing cycles and twist angles.
Post-flex inspection for barrier performance through leak detection or gas permeability tests.
Application across multilayer films, metallized films, and high-barrier packaging.

The goal is to simulate actual distribution environments, identifying whether the packaging maintains its barrier properties after flexing.

Flex Tester Use Cases in Snack Food Packaging

A flex tester is vital for:

Testing high-barrier pouches and wraps.
Evaluating foil-based or metallized packaging.
Simulating transportation wear for quality verification.

Combining the flex test with oxygen transmission rate (OTR) or water vapor transmission rate (WVTR) measurements gives a complete picture of packaging integrity.

How to Perform a Snack Food Packaging Barrier Test

To carry out an effective snack food packaging barrier test, follow these steps:

Provberedning: Cut representative samples of the packaging film or bag.
Flex Testing: Use the gelbo flex testare to apply mechanical stress based on ASTM F392 parameters.
Barrier Evaluation: After flexing, test for leaks using a vacuum decay test, bubble leak test, or measure OTR/WVTR.
Data Analysis: Compare results to acceptable barrier thresholds.
Report Generation: Document the test method, parameters, and findings to support compliance and decision-making.

For best results, ensure environmental conditions such as temperature and humidity are controlled during testing.
