Packaging Material Testing

Packaging material testing is a crucial aspect of the packaging industry to ensure the safety, quality, and effectiveness of packaging materials used for various products. The primary purpose of packaging is to protect the contents, maintain product integrity, and meet regulatory requirements. Testing helps identify potential issues and ensures that packaging materials meet specified standards.

Primary Packaging Materials:

  • Paper
  • Paperboard
  • Corrugated Fiber Board
  • Plastics – Rigid
  • Plastics – Fabric
  • Woven Fabric

Ancillary Packaging Materials:

  • Tapes
  • Labels
  • Adhesives
  • Inks
  • Straps
  • Closures

Here are some key aspects of packaging material testing:

Physical Properties Testing

    • Tensile Strength: Measures the maximum load a material can withstand before breaking.

    • Elongation: Determines the ability of a material to stretch before breaking.

    • Burst Strength: Measures the pressure a material can withstand before bursting.

    • Abrasion Resistance: Evaluates a material’s resistance to wear and tear.

Barrier Properties Testing

    • Moisture Vapor Transmission Rate (MVTR): Measures the permeability of a material to water vapor.

    • Oxygen Transmission Rate (OTR): Determines the amount of oxygen that can pass through the material.

    • Gas Permeability: Measures the permeability of gases through the material.

Chemical Resistance Testing

    • Resistance to Solvents: Evaluates how well the material withstands exposure to various chemicals.

    • Acid and Alkali Resistance: Assesses the material’s resistance to acidic or alkaline substances.

Printability and Ink Adhesion Testing

    • Print Quality: Ensures that the printing on packaging is legible and meets visual requirements.

    • Ink Adhesion: Measures how well ink adheres to the surface of the packaging material.

Seal Strength Testing

    • Peel Strength: Measures the force required to peel apart the layers of a sealed package.

    • Tack and Seal Initiation: Assesses the initial sealing characteristics of packaging materials.

Impact Resistance Testing

    • Drop Test: Simulates the impact of a package being dropped during handling or transportation.

    • Transportation scenarios.

Environmental Testing

    • Temperature and Humidity Testing: Evaluates how packaging materials perform under different environmental conditions.

    • UV Resistance: Measures the material’s ability to withstand exposure to ultraviolet light.

Transportation Testing
  • Vibration and Shock Testing: Simulates the conditions during transportation to assess the durability of the packaging.
  • Box compression testing
  • Bursting strength
  • drop test
  • Incline impact test
  • Low Pressure testing
