This impact strength test can only prove this foil laminate is of enough property to be processed into pouches, however, to finalize standing pouch with good strength, the bag-making operations like heat sealing temperature, balanced pressure, heat period are quite critical, so usually we will have to perform further test on final package, to decide if 3.3 kilograms tomato sauce screw cap pouch is strong enough.
Pressure test or anti-pressure test on this plastic spout pouch is going to apply a certain weight/pressure on the package which is usually filled with water, and the pressure condition will last for a certain period like 30 seconds or 1 minute to check if this 3000 grams tomato sauce plastic closure package is strong enough.
