Plastic Bottle Caps

The bottles in plastic found the wide application in the food, the industries of drink and beer these days. The bottle in plastic of cola, the bottle of juice in plastic and the bottle of beer everywhere can be found in our daily life. With its wider applications, there were conditions more of the standard one for his quality check. Since to wind the force and seal the execution has direct relation to the quality and the periods of storage of the contents in the packets, sealing force of executions and moment of torsion of closing of bottle became the common home of manufacturers of bottle in plastic among the various indices of check of quality. Labthink Instruments (www. labthink. cn ) The reports on the test of execution of seal of bottle in plastic, the bottle closing winds the force and opens the force with Labthink PARAM LSSD-01 Escapes and the Seal Forces Detector and PARAM NJY-20 Testers of Moment of Numerical torsion.

1. The Bottle in plastic Sealing Executions and the Trip/Lock of Closing of Bottle Trying

The property of barrier of equipment of bottle in plastic would influence directly the period of guarantee of quality. The better execution of barrier, the period of guarantee of longer quality. Nevertheless, does not import the individual property of barrier of body of bottle and of closing of bottle are good; the conjunction place is the only place where the escape would arrive. Therefore, the execution sealing closing of bottle is the informer more basic for the receptacle seals the execution.

GB/T 17876-1999 declared that the specified conditions for the bottle closing sealing the execution essay. According to their different applications, the bottle closings for always the drink and the carbonated drink are different methods. The closing for always the drink should cut his ring of flight proof (the bar), and pressurize to 200KPA in PARAM LSSD-01 Detectors of Escape and Seal for 1 minute (submarine). Observe the escape; if no, increase the pressure to 1207KPA for 1 minute and observes if the bottle closing stumbles.

Labthink PARAM LSSD-01 Detectors of Escape and Seal is for the quantitative essay to seal executions; Labthink PARAM MFY-01 Testers of Escape is for the quick quality essay.

2. The Value of Moment of torsion Trying for Cork/Closing of Bottle- the Force of Lock &the amplifier; Open the Force

In the au-dessus of mention sealing the execution essay, a certain force of moment of torsion of cork of bottle is demanded. Indeed, to clog the force of moment of torsion of cork (the bottle cork opens and locks the force) is one of the principal factors affecting the execution sealing. On the force of moment of torsion would bring big difficulties for open and winds cup of bottle, and thus, reduce convenience. The insufficient force of moment of torsion would affect the execution of seal of the receptacle, and more can have for result the escape during the transportation. Now, the conception of packet is designated to bring more convenience for quickly the consumption, and the easy frankness of cork of bottle is one of the objectives. While treating such essay, GB/T17876-1999 is the norm, and the ring of trade proof should be cut before to try.

The execution sealing bottle in plastic is the factor more important affecting the escape of packet and the product deterioration. Simplicity and seal the excellent open executions can be guaranteed by the reasonable check to seal the execution and the torsion moment estimates. The property of barrier of bottles in plastic, including the quantity of transmission of gas and the quantity of transmission of vapor of water, should be checked also if as to guarantee the product quality during the period of shelf life.
