The Torque Value Testing for Bottle Cap/Closure- Lock Force & Open Force

The Torque Value Testing for Bottle Cap/Closure- Lock Force & Open Force

Bottle cap torque force (bottle cap open and lock force) is one of the main factors affecting the sealing performance. Over torque force would bring great difficulties for open and winding up of bottle cup, and thus, reduce the convenience. Insufficient torque force would affect the seal performance of the container, and may further result in the leakage during transportation. Now, package design is designated to bring more convenience for fast consumption, and easy openness of bottle cap is one of the aims. When dealing such testing, ASTM D2063,ASTM D3198, ASTM D3474 are the standard, and craft-proof ring should be cut before testing.

The sealing performance of plastic bottle is the most important factor affecting package leakage and product deterioration. Excellent open easiness and sealing performance can be guaranteed through reasonable control of sealing performance and torque value. The barrier property of plastic bottles, including gas transmission quantity and water vapor transmission quantity, should also be controlled so as to guarantee the product quality during shelf-life period.

Development of Integral Package Barrier Property Testing

Development of Integral Package Barrier Property Testing

Abstract: The varied shapes of packages are one of the obstacles for their integral barrier property testing. With the development of barrier property testing technology, the technique for integral package barrier property testing has also made great progress with various kinds of testable packages. This article makes a detailed introduction of the development of integral package barrier property testing and relevant testing cases.
Key Words: package, transmission rate, pouches, blister, differential pressure method

 

In the past, barrier property testing was only for films, which has brought great inconvenience to end package manufacturers and users. Most raw materials they bought could make barrier property testing, but the finished packages, owing to the lack of testing techniques, would bring hidden dangers to end-product quality. The difficulty for testing lies in the varied shapes of packages. However, owing to the promotion of barrier property testing, integral package barrier property testing has made great progress with more kinds of testable packages. This article makes a detailed introduction on the development of integral package barrier property testing and relevant testing cases.

1. Introduction to Integral Package Barrier Property Testing Techniques

Keeping certain shapes is the most basic characteristic for packages. Therefore, keeping the package intact is the first thing when testing. Secondly, the seal performance of testing instruments and sampling accessories should be guaranteed. Those two points are difficult to achieve for package testing, compared with film and sheet testing.

1.1 Equal Pressure Method Package Oxygen Transmission Rate Testing Techniques

The testing principles of equal pressure method oxygen transmission rate for both films and packages are similar. First, the preconditioned specimen separates the transmission chamber into two separate gas flow systems. Testing gas flows in one side of the package, such as pure oxygen or mixed gas with oxygen; high pure carrier gas flows in the other side. Though the gas pressure of two sides are the same, oxygen sub-pressures are different. Therefore, under the gradient of oxygen concentration, oxygen transmits through package and is carried to the sensor by the carrier gas. The sensor will measure the oxygen quantity in the carrier gas flow precisely, so as to work out the oxygen transmission rate of the tested package. If only specimen preparation issue can be effectively resolved, various packages are testable by this method. Testing subjects can be the integral package or a part of it, including various bottles, the connecting part of bottle cup and bottle body, bottle cup, capsule, blister, tube, injection, IV bags, flexible pipe and various ball-shape packages. Besides, the contents of tested packages can be in or not, so as to provide most reliable data for package evaluation in actual application and quality change of contents.

At present, ASTM F 1307 is the only testing standard for equal pressure method, and is applicable for all packages that can produce dry spaces inside. Moreover, equal pressure method oxygen transmission rate testing techniques can also be used under humid circumstances, and can further provide an environment with certain humidity in or out side the package.

1.2 Differential Pressure Method Package Gas Transmission Rate Testing Technique

Keeping the package shape intact is the main difficulty for differential pressure method package gas transmission rate testing. Owing to the pressure difference between the inner and outside of the package, the tested specimen might be destroyed by pressure difference without appropriate means to keep its shape, and result in meaningless testing results, or even no testing data. At present, in the field of differential pressure method gas transmission rate testing research, Labthink has made breakthrough. At the same time, Labthink has successfully extended integral package gas transmission rate testing from oxygen alone to many common inorganic gases. However, there are not many kinds of subjects can be tested with this method.

1.3 Weighing Method Package Water Vapor Transmission Rate Testing Technique

Weighing method water vapor transmission rate testing is the traditional method for package water vapor transmission rate testing; the relevant testing methods are: GB/T 6981-1986, GB/T 6982-1986 and ASTM D 3079-94. The testing process is as follows: first, put the desiccant (container is permitted) into the specimen, and seal the open place on the package wall. After preheating, put the specimen into the testing chamber with constant humidity and constant temperature for humidity and temperature test. Then, weigh the weight of the specimen at proper intervals according to the water vapor transmission performance of the package. When the transmission reaches stability, calculate the integral package water vapor transmission rate on the added weight of the specimen. However, open a mouth on the package wall is not practical, and it would always lead to operational failure and corresponding failure. Therefore, in the standards for pharmaceutical packaging materials, the desiccant is changed into distilled water or other testing solvents when using this method. Thus, there is no need to open and close the package mouth repeatedly; and the only thing needs to do is to weigh the package at certain intervals. However, the long testing periods and precision limit are the inherent shortcomings of this method.

1.4 Sensor Method Package Water Vapor Transmission Rate Testing Technique

Sensor method and different pressure method package water vapor transmission rate testing techniques are similar in the testing principle: separate the transmission cell into two isolated gas flow system by the package, one side of the package flows the carrier gas (dry); and another side is in a relative humidity. Thus, a stable water vapor concentration difference exists between the two sides of the specimen (relative humidity). Under the influence of water vapor concentration difference, water vapor transmits through the package wall and is carried to the sensor. The sensor measures the water vapor content in the carrier gas accurately so as to further calculate water vapor transmission rate of the specimen. This method is applicable for bottles, pouches, capsules, blisters, IV packages, flexible pipes and other forms of packages. Now, the testing accuracy of this method is up to 0.001g/pkg·d; the testing period is only 3 to 4 days; and the testing process is completely automatic.

2. Typical Application Examples

Usually, package barrier property testing is for bottles or certain parts of the bottle. However, package is not limited to bottle, pouches, flexible pipe and PVC trays also have broad applications, among which, the testing for pouches and small-sized package (e.g., blister) are more emphasized.

2.1 Pouches

The space maintenance of the pouches should be taken care of when using equal pressure method or sensor method. As to pouches, if the pressures inside and outside can not be well controlled, it would result in less gas transmission area and lead to data error. Therefore, the pouches should be bulged during precondition period, and it can be achieved by putting certain quantities of gas or other accessories into the pouches. At the same time, the space inside pouches should also be kept during testing process so as to avoid shriveling, especially for thin food pouches. As to IV bags, jelly pouches, stand up pouches and other thick pouches, their shriveling probability is less.

When using weighing method, how to keep the space inside the pouches is also a problem. Meanwhile, how to seal pouches after filling distilled water inside should also be considered, which increase the difficulty in actual operation.

2.2 Blisters

Blisters are usually of small volume. Therefore, they can only be tested by equal pressure method or sensor method. Furthermore, the specimen preparation can only be accomplished with customized accessories. Meanwhile, the adjustment of flowing speed during testing process should also be cautious so as to avoid sudden pressure increase and decrease caused by violent change of gas quantity, and thus, avoid influences to the specimen status.

Usually, the testing accessories for blisters are also applicable for small-sized package testing, such as capsule; and can expand to more kinds of small-sized packages conveniently.

3. Conclusions

The development of integral package barrier property testing techniques has greatly expanded the scope of barrier property testing. Now, the testing subjects have expanded to nearly all the packages, which have brought fundamental testing reform for package manufacturers and users. Meanwhile, with the leak and seal testing as well as headspace gas analysis, a more integral, effective and accurate package result can be guaranteed.

Introduction to Plastic Bottle (Beverage Bottle and Beer Bottle) Sealing Performance Testing

Introduction to Plastic Bottle (Beverage Bottle and Beer Bottle) Sealing Performance Testing

Plastic bottles have found wide application in food, beverage and beer industries nowadays. Plastic cola bottle, plastic juice bottle and beer bottle can be found everywhere in our daily life. With its wider applications, there have been more standard requirements for its quality control. Since winding up force and sealing performance have direct relationship to storage quality and periods of the contents inside the packages, sealing performances and torque force of bottle closure have become common focus of plastic bottle manufacturers among various quality control indexes. Labthink Instruments (www.labthink.cn ) briefs on the test of plastic bottle seal performance, bottle closure winding up force and open force with Labthink PARAM LSSD-01 Leak and Seal Strength Detector and PARAM NJY-20 Digital Torque Tester.

1. Plastic Bottle Sealing Performances and Bottle Closure Trip/Lock Testing

The barrier property of plastic bottle material would directly influence the quality guarantee period. The better barrier performance, the longer quality guarantee period.  However, no matter the individual barrier properties of bottle body and bottle closure are good; the conjunction place is the only place where leakage would occur. Therefore, the sealing performance of bottle closure is the most basic indicator for container sealing performance.

GB/T 17876-1999 has stated specified requirements for bottle closure sealing performance testing. According to their different applications, bottle closures for still beverage and carbonated beverage are of different methods. Closure for still beverage should cut its theft-proof ring (bar), and pressurize to 200kPa in PARAM LSSD-01 Leak and Seal Detector for 1 minute (underwater). Observe the leakage; if not, increase the pressure to 1207kPa for 1 minute and observe whether the bottle closure trips.

Labthink PARAM LSSD-01 Leak and Seal Detector is for quantitative testing for sealing performances; Labthink PARAM MFY-01 Leak Tester is for rapid qualitative testing.

2. The Torque Value Testing for Bottle Cap/Closure- Lock Force & Open Force

In the above mentioned sealing performance testing, a certain bottle cap torque force is required. Actually, bottle cap torque force (bottle cap open and lock force) is one of the main factors affecting the sealing performance. Over torque force would bring great difficulties for open and winding up of bottle cup, and thus, reduce the convenience. Insufficient torque force would affect the seal performance of the container, and may further result in the leakage during transportation. Now, package design is designated to bring more convenience for fast consumption, and easy openness of bottle cap is one of the aims. When dealing such testing, GB/T17876-1999 is the standard, and craft-proof ring should be cut before testing.

The sealing performance of plastic bottle is the most important factor affecting package leakage and product deterioration. Excellent open easiness and sealing performance can be guaranteed through reasonable control of sealing performance and torque value. The barrier property of plastic bottles, including gas transmission quantity and water vapor transmission quantity, should also be controlled so as to guarantee the product quality during shelf-life period.
