ISO 11093-5 Recycled Board Adhesive Strength
The ISO 11093 series of standards provides a comprehensive approach to evaluating the physical and mechanical properties of recycled paperboard. Specifically, ISO 11093-5:2017 Recycled Board Adhesive Strength focuses on assessing the adhesive strength between layers of recycled board after processing. This test is critical for manufacturers looking to ensure that their products meet stringent quality and performance requirements.
The adhesion between paperboard layers impacts several aspects, including:
- Product durability and longevity
- Recycled content integrity
- Packaging performance under real-world conditions
The test method outlined in ISO 11093-5 involves bonding two specimens cut from recycled board using a specified adhesive. The bonded specimens are then subjected to a tensile force until the bond fails, and the peak load at failure is recorded.
This process ensures that recycled content within the paperboard remains functional and performs as expected in end-use applications such as corrugated boxes or folding cartons.
The test setup typically includes:
- Two specimens of recycled board
- A specified adhesive
- A tensile testing machine capable of applying controlled force
The specimens are prepared by cutting them to a standard size, usually 150 mm x 75 mm. The cut edges are smoothed using sandpaper or another appropriate method. After bonding the specimens with the specified adhesive, they are allowed to cure for an appropriate period.
Once cured, the bonded samples undergo tensile testing. The force required to separate the two layers of paperboard is measured and recorded. This value provides a direct indication of the bond strength between recycled paperboard layers.
Understanding the results from this test allows manufacturers to:
- Evaluate the effectiveness of their recycling processes
- Optimize adhesive selection for specific applications
- Ensure compliance with industry standards and customer expectations
- Demonstrate environmental responsibility through robust recycled content use
The test results are typically reported as a single value representing the peak tensile force required to separate the bonded layers. This data is crucial for quality control, R&D, and regulatory compliance in the paper and pulp industry.
In addition to the mechanical properties evaluated by this test, it's important to consider other factors that influence the performance of recycled board:
- Recycled content percentage
- Type and concentration of filler materials used during recycling
- Solid-state chemical changes in fibers during processing
- Paperboard formation variables such as caliper, grammage, and surface finish
The ISO 11093-5 test serves as a critical tool for addressing these considerations by providing empirical data on the adhesive strength of recycled board.
By understanding how different parameters affect bond strength, manufacturers can make informed decisions about process optimization and material selection. This not only enhances product performance but also supports sustainability goals by maximizing the use of recycled materials.
Applied Standards
The ISO 11093 series is widely recognized for its comprehensive approach to evaluating the physical properties of recycled paperboard. The standards are designed to provide a consistent and reliable method for testing various parameters, including:
- Bulk density
- Folding endurance
- Compressive strength
- Tear resistance
- Water resistance
- Adhesive strength (ISO 11093-5)
Among these, ISO 11093-5 specifically focuses on the adhesive strength of recycled paperboard layers. This standard is applicable to a wide range of products that incorporate recycled board in their construction.
The test procedure outlined in ISO 11093-5 ensures that the results are consistent and reproducible, which is essential for quality control and regulatory compliance. The standard specifies:
- Specimen dimensions
- Cure times
- Type of adhesive to be used
- Tensile testing parameters
The use of international standards like ISO 11093-5 helps manufacturers ensure that their products meet the highest quality and performance expectations. By adhering to these standards, companies can:
- Ensure consistency across production batches
- Facilitate global trade by meeting international standards
- Build trust with customers through transparent testing practices
- Demonstrate their commitment to sustainability and environmental responsibility
The standard is particularly useful for companies that rely heavily on recycled content in their products, as it provides a clear framework for evaluating the performance of these materials.
In addition to ISO 11093-5, other relevant standards include:
- ISO 2786:2014 - Specifications for paper and board used for corrugated containers
- EN 13937:2017 - Specification for recycled paperboard
- ASTM D5907-09e1 - Standard test method for tensile properties of adhesive bonds in wood-based composites
These standards, when used together, provide a robust framework for evaluating the physical and mechanical properties of recycled paperboard.
Industry Applications
The ISO 11093-5 Recycled Board Adhesive Strength test is particularly relevant to several key industries that rely heavily on recycled materials. These include:
- Packaging and shipping
- Paper and pulp manufacturing
- Corrugated container production
In the packaging industry, recycled paperboard plays a crucial role in creating strong, durable containers for transporting goods. The adhesive strength test ensures that these containers can withstand the rigors of transportation without compromising structural integrity.
The paper and pulp manufacturing sector benefits from ISO 11093-5 by being able to evaluate how well their recycling processes are performing. By testing bond strength, manufacturers can identify areas for improvement and optimize their operations to produce high-quality recycled board.
For corrugated container producers, the test is essential in ensuring that the corrugated boards used in packaging meet strict quality standards. This helps prevent issues such as delamination during shipping, which could lead to product damage and customer dissatisfaction.
The results of this test are particularly valuable for companies looking to increase their recycled content while maintaining or improving product performance. By adhering to international standards like ISO 11093-5, these organizations can:
- Enhance the durability of packaging materials
- Reduce environmental impact by using more recycled content
- Increase customer trust through transparent and consistent quality control practices
The test results are also useful for procurement departments in selecting suppliers who meet stringent quality requirements. This ensures that companies can source high-quality recycled paperboard, which is essential for maintaining product performance.
