Testing the Barrier Properties of Mixed Nut Packaging

Product catalog summary
Introduction
Mixed nuts are a nutritious snack prone to spoilage due to their high fat content, which can oxidize and become rancid. Effective packaging is essential to maintain quality and extend shelf life.

Packaging Materials
Mixed nuts are typically packaged in flexible pouches or flow-wraps made from multi-layer films. These films often include a barrier layer of metallized films, aluminum foil, or EVOH to minimize oxygen and moisture transmission.

Testing Procedures
To ensure packaging effectiveness, several tests are conducted:
  • Flex Testing: ASTM F392 is used to simulate real-world conditions by flexing or creasing the packaging material.
  • Flex Durability Testing: Labthink C681M Flex Durability Tester assesses the flex durability of films by simulating kneading and creasing behaviors.
  • Oxygen Transmission Rate (OTR) Testing: Measures the rate of oxygen permeation using the differential pressure method (ISO 2556).
  • Water Vapor Transmission Rate (WVTR) Testing: Measures the rate of water vapor permeation to ensure moisture protection.


Testing Equipment
Labthink C406H Oxygen/Water Vapor Transmission Rate Test System uses Coulometric oxygen sensors and infrared water vapor sensors, adhering to standards like ASTM D3985 and ISO 15106-2, to provide precise testing for high and medium gas barrier materials.

Conclusion
Testing the durability and barrier properties of mixed nut packaging is crucial for product quality and shelf life. By employing comprehensive testing methods, manufacturers can select materials that protect against oxygen, moisture, and physical damage, ensuring a fresh product for consumers. Labthink promotes collaboration for quality control and offers advanced testing solutions.

Testing the Barrier Properties of Mixed Nut Packaging-1

Labthink Instruments Co., Ltd. [email protected] +86-531-85068566 Testing the Barrier Properties of Mixed Nut Packaging Mixed nuts are a popular and nutritious snack. However, their high fat content makes them susceptible to spoilage. Oxidation of these fats leads to rancidity, affecting taste, aroma, and nutritional value. Proper packaging is crucial for maintaining the quality and extending the shelf life of mixed nuts. Mixed nuts are commonly packaged in flexible pouches or flow-wraps made from multilayer films. The barrier layer within these packages commonly consisting of metallized films, aluminum foil, or EVOH. These materials minimize oxygen and moisture transmission. To ensure packaging effectiveness, several tests are conducted. Flexible packaging undergoes stress during production, transportation, and handling. Tests like ASTM F392 (Flex Testing of Flexible Barrier Materials) are crucial. This involves repeatedly flexing or creasing the packaging material to simulate real-world conditions.

Testing the Barrier Properties of Mixed Nut Packaging-2

Labthink Instruments Co., Ltd. [email protected] +86-531-85068566 Labthink C681M Flex Durability Tester is professionally applicable to the determination of flex durability of flexible films, composite films and coating films. The instrument can simulate the kneading and creasing behaviors of films happened during production, processing and transportation. The flex durability can be obtained by measuring the changes in number of pinholes or barrier properties after test, which can provide quantitative basis for package design and practical usage. After flexing, the OTR and WVTR are re-tested...
