Testing Standard:
TAPPI T837 Measuring the Bond Strength of a Glued Manufacturer’s Joint
Standard Number
TAPPI T837
Standard Title
Measuring the Bond Strength of a Glued Manufacturer’s Joint
Overview:
TAPPI T837 Test Method is used to verify sufficient glue type, application, and bond were established during manufacturing. Purple Diamond Testing offers TAPPI T837 Measuring the Bond Strength of a Glued Manufacturer’s Joint as part of our packaging compliance and validation services.
Rationale:
TAPPI T837 – Measuring the Bond Strength of a Glued Manufacturer’s Joint. Data collected from utilizing this test method is critical when evaluating the shipper’s ability to contain the intended contents. The strength of the manufacturer’s joint is determined through a shear test with the max force required to separate the glue bond recorded. Insufficient glue application or inadequate glue bond are common manufacturing issues that cause the glue joint to fail. Testing to TAPPI T837 can help identify the defects mentioned above.
Key Points:
- Establishes adhesive comparison used in failure analysis
- Evaluates adhesive and linerboard compatibility
- Use to identify potential issues and any design flaws
- Utilize this test method to ensure quality control
