All food companies should strengthen the composite fastness testing of cover film materials.
. By testing the bursting pressure of packaging bags, the weak parts of the packaging and the overall stress level can be verified, providing reference for companies to control the quality of packaging materials, improve heat sealing processes, and adjust packaging processes.
The water vapor barrier performance of aluminized BOPP tape is one of the properties that relevant companies should focus on monitoring. This article analyzes the water vapor barrier performance by testing the water vapor transmittance of aluminized BOPP tape.
Why does the packaging of finished food products that are convenient for brewing leak ? What properties should be paid attention to when the packaging materials used in boxes (barrels) of instant noodles enter the factory?
testing the burst pressure of packaging bags, the weak parts of the packaging and the overall stress level can be verified, providing reference for enterprises to control the quality of packaging materials, improve heat-sealing processes, and adjust packaging processes.
At present, the test methods for film shrinkage are mainly oil bath method, drying oven method and air heating method.
This article provides a simplified testing procedure for air permeability test of the inner tubes for automotive tires for your reference.
While protecting the food, it will have a greater impact on the packaging bag when it is squeezed or impacted by an external force. The packaging bag is required to have a higher strength.
The former uses the weight of the falling dart breaking through the film to represent the impact resistance of the material, while the latter uses the energy lost to break through the film to represent the impact resistance of the material.
Therefore, all enterprises should strengthen the monitoring of the toughness related indicators of POF shrink film to ensure its excellent toughness.
the packaging materials used for table salt should have high puncture resistance.
Why do milk powder packaging appear deflated? What should we do if the liquid milk packaging leaks or breaks?
