LSSD-01 Leak and Seal Strength Tester is suitable for the quantitative measurement of sealing strength, heat sealing quality, bursting pressure of the whole bag and sealing leakage performance of soft package.

Product Introduction

How It Works?

View this video to learn how this tester works.

LSSD-01 Leak and Seal Strength Tester is suitable for the quantitative measurement of sealing strength, heat sealing strength, binding strength, overall sealing performance, pressure resistance strength, cap body connection strength, bursting pressure and shedding strength. It is widely used in the soft package, plastic pilfer-proof caps, flexible pipes, etc.

Product Features

  • 7-inch color touchscreen with graphical user interface (GUI)
  • Meets ASTM and ISO standards
  • Positive pressure principle, simple operation, stable and reliable performance.
  • Wide test range for different applications.
  • Dual test methods of restraint distension and unrestraint distension for customer’s choice
  • Different test modes of Seal Strength, Burst, Creep and Creep to Failure to meet different test requirements.
  • The "one key" operation in the test process is intelligent and efficient.
  • Test results automatic statistics and printing.
  • Test accessories support, flexible test mode, compatibility and diversification.
  • Standard USB interface,software supports test results of multiple units display.
  • The test data can be shared between LAN and Internet.

Test Principle

LSSD-01 adopts positive pressure method: after the gas with certain pressure fills into the sample with setting parameters, the pressure sensor detects the change of air pressure inside the sample to judge the overall sealing performance of the sample, and tests the pressure resistance and bursting performance of the sample with the specified air pressure.

Test Standards

This test instrument conforms to many national and international standards:

ASTM F1140: Burst & creep test for packages (without restraining plates)
ASTM F2054: Burst test (with restraining plates)
ASTM F2096: Bubble leak test (with water tank) (optional)
ISO 11607: Packaging for terminally sterilized medical devices


Basic Applications

Plastic Composite Bags
Test the pressure rupture of various packaging bags, such as plastic film, aluminum film, paper-plastic composite, aluminum-plastic composite, etc.

Flexible Tubes
Including various flexible tubes used in daily chemical products and other industries, e.g. flexible tubes of toothpaste, face cream, cosmetics, pharmaceutics and food

Creep Test
Including various packaging bags and boxes

Creep to Failure Test
Including various packaging bags and boxes

Extended Applications

Burst Test of Blister Packs
Including various blister packs

Aerosol Valves
Test seal performance of various aerosol valves, e.g. valves of pesticide, hair spray, auto spray paint and medical spray packages

Three-sided Sealing Materials
Test withstand pressurization stress of packaging bags with three-sided seal and one-sided open

High Pressure Test
The maximum test pressure could reach 1.6 MPa

Pilfer-proof Closures
Test seal performance of various pilfer-proof closures, e.g. closures used in packages for Coke, mineral water, beverage, edible oil, sauce (soy, vinegar and cooking wine), three-piece cans (beer and beverage) and paper cans (cylinder shape for potato chips )
