Understanding Burst Value

Burst value is a critical quality metric for paper and packaging materials. It measures the relationship between a material's burst strength and its weight, providing insight into material efficiency and quality.

Formula

[\text{Burst Value} = \frac{\text{Burst Strength (kPa)}}{\text{Grammage (gf/m²)}}]

The burst value is expressed in kPa/(gf/m²), representing kilopascals per gram-force per square meter.

Example Calculation

For a packaging material with:

  • Burst Strength: 65.0 kPa
  • Grammage: 30.0 gf/m²

Calculation:

[\text{Burst Value} = \frac{65.0}{30.0} = 2.17 \text{ kPa/(gf/m²)}]

This burst value of 2.17 kPa/(gf/m²) indicates good quality packaging material with efficient strength-to-weight ratio.

Interpreting Results

High Burst Value (> 2.5): Indicates excellent material quality with high strength relative to weight. Ideal for premium packaging applications.

Medium Burst Value (1.8-2.5): Represents standard quality material suitable for most general packaging needs.

Low Burst Value (< 1.8): Suggests lower quality material or heavy weight relative to strength. May require thicker material or reinforcement for demanding applications.

Applications

Burst value testing is commonly used in:

  • Corrugated board manufacturing
  • Paper mill quality control
  • Packaging material selection
  • Material specification compliance
  • Cost-performance optimization

Frequently Asked Questions

Burst value is a measure of paper or packaging material quality that indicates how much burst strength is provided per unit of material weight. It is calculated by dividing burst strength by grammage.

Burst value is expressed in kPa/(gf/m²), which represents kilopascals per gram-force per square meter. This shows the strength-to-weight ratio of the material.

Burst value helps assess packaging material efficiency by showing how much strength is obtained per unit weight. Higher burst values indicate better quality material that provides more strength without adding excessive weight.

Typical burst values range from 1.5 to 3.0 kPa/(gf/m²) depending on the material type and application. Higher values generally indicate better quality packaging material.
