2. Testing and Analysis of the Heat Seal Strength of Dairy Flexible Packages

Heat seal is an important index for packaging materials. Every kind of packaging material needs to be manufactured into bags to pack kinds of products, of which, heat seal is a necessary procedure to accomplish packaging process. The seal of dairy products needs to achieve certain strength to burden certain gravity of the content and to avoid breakage during circulation process. Labthink XLW (PC) Auto Tensile Tester can accomplish this task professionally. This instrument can automatically read the data and automatically judge the strength value as well as carry out data superposition of the same specimen group. Besides, labs need to carry out seal strength/heat seal strength testing with the additional help of heat seal tester to prepare the specimen.

3. The Testing and Analysis of the Coefficient of Friction of Dairy Flexible Packaging Materials

The coefficient of friction tests are for the control and adjustment of open easiness of flexible packages as well as packing speed of packing machines, and other production quality and processing indexes. Nowadays, Chinese instruments have caught up with the international technology with unique coefficient of oscillation setting for films, paper of different qualities. The intellectual data processing can effectively shows credibility of the results. Large LCD displays the real time curve and, thus, shows the evenness of the coefficient of friction directly. For packaging material manufacturers, they can decide the type and quantity of the smoothness agent and open easiness agent to control coefficient of friction through testing so as to help them with a better quality control of raw materials. At present, there are not many existing standards for coefficient of friction of dairy products. The existing ones are GB10006, ASTM D 1894 and ISO 8295, etc. But, these standards are of different testing requirements which bring the manufacturers into great trouble. Labthink MXD-02 Coefficient of Friction Tester is multi-method applicable so as to resolve the problem of method confusion for the manufacturer.

4. Leakage Testing and Analysis of Dairy Packages

Leakage is also an important index of flexible packages, especially for dairy products, and has great influence on product quality. Inferior sealing performance is the main cause of the following leakage and deterioration. There are several methods to test leakage, and the most common method is by leak tester. Utilize vacuum method, and keep the specimen under pressures of -30kPa, -50kPa, -70kPa and -90kPa for 0.5 minute respectively. Pay attention to the leakage during vacuumizing and vacuumed periods if successive bubbles appear. Isolated bubble will not be regarded as leakage. Through the testing of leakage, we can evaluate the quality of the packages and judge the corresponding sealing processing.

The above-mentioned method is visual and quality testing method. If quantitative seal and leak performance needs to be tested, positive pressure method testers can be adopted. For example, Labthink LSSD-01 Leak and Seal Strength Detector.

5. The Testing and Analysis of the Composite/Bond Strength of Dairy Packaging Materials

The flexible packages of dairy products, like aseptic pack, are mainly made of composite plastics or composite paper, of which, the stronger combined/bond strength is preferred as well as favorable corresponding tear resistance and destructive resistance. After the composite materials have been processed into bags, they are easy to be influenced by the wet or chemical ingredients in the fierce environment and the combined layers are easy to be injured. Using high viscosity tackiness agent will surely achieve high quality composition, but with more production costs.

The qualified and cost-saving composite material needs to undergo quality-testing analysis for the layers so as to find proper composition indexes. Nowadays, both the domestic and abroad tensile testers can execute peeling tests, but they are of the universal type with simple calculation. The Auto Tensile Tester Manufactured by Labthink Instruments Co. Ltd. is specializing in the test of flexible package line and in complete compliance with GB 8808-88 for the peeling tests of flexible materials. This tensile tester has the following merits: unique both ends breaking-off function, the strength values are obtained with integration method of the middle part; accurate testing results with real time strength value and curve display for binder/tackiness agent evaluation; to know the evenness of the material with the fluctuation of the curves; to know the stability of the group samples through data curve superposition so as to adjust processing and composite indexes.

6. Other Quality and Analysis of Dairy Packages

The ultimate aim of dairy packages is for promotion. The well printed dairy packages will definitely attract the sight of more customers and expand market share. The density & density difference, color & color difference, superposition-rate and printing contrast can be measured by X-rite Densieye; but for the testing of ink layer bond strength or the abrasion resistance of dairy packages, Labthink YGJ-02 Adhesive Tensile & Shear Tester and BLJ-02 Disk Stripping Tester can be adopted so as to achieve quality control purpose in printing and color.

The above dairy flexible package testing indexes are critical for processing development and quality improvement.

A. Moisture Barrier Property Testing of BOPP Cigarette Film

High moisture barrier property performance is a must for cigarette package so as to avoid deterioration caused by moisture. At present, this factor is not fully noticed by the cigarette manufacturers. Labthink PARAM TSY-T1H is developed according to ASTM E96, ISO 2528 and other standards to test moisture transmission rate for materials. The lower WVTR the better. But, higher barrier property means more costs. Therefore, the common data is less than 10g/m2.day or 5g/m2.day.

B. Thickness of BOPP

Thickness of BOPP cigarette film is the basic film performance index. Uneven thickness would influence the tensile strength and permeability as well as the following procedures. Thicker cigarette film would have better stiffness with better visual performance. But, the cost would also be great. In order to find the balanced solution, high precision thickness tester is needed. Labthink PARAM CHY-C2 is the lab thickness tester with the precision up to 0.1um. When testing thickness in different directions, deviation must be controlled within 3% usually. Meanwhile, the edge thickness of BOPP film has to be measured.

C. BOPP Cigarette Film Tensile Strength, Elongation and Elastic Modulus

Cigarette package requires high tensile strength of BOPP films, which can greatly reduce the breakage during packaging process. Generally, 140N/mm2 vertically and 200N/mm2 crosswise are required. Elongation rate is for analysis of incision easiness of films. Cigarette packaging industry is different from other industries. Higher elongation rate is not better. Max. limitations of 200% vertically and 80% crosswise can guarantee easy incision and assembling smoothness. Other industries require those two indexes. But cigarette package requires more detailed requirements on incision easiness during high speed production. Therefore, Elastic Modulus testing is also put forward. Labthink PARAM XLW(PC) Auto Tensile Tester is the professional tester for film and its tensile strength with Elastic Modulus testing. Low Elastic Modulus would lead to worse stiffness, unsuccessful production procedure and inferior incision easiness as well as package breakage and film obstruction.

Commonly, Elastic Modulus is required to be above 2000N/mm2 for cigarette film. However, when testing Elastic Modulus, testing conditions and temperature must be emphasized. Otherwise, the results will fluctuate greatly. Therefore, testing condition must be stated.

D. The Heat Seal Strength of BOPP Cigarette Film

BOPP is required to have high heat seal strength and wider heat seal scope by the cigarette industry, so as to improve packing speed and proper operation. If the heat seal temperature is higher, it would lead to wrinkle because of increased BOPP film shrinkage. Therefore, proper heat seal temperature should be chosen so as to avoid unstable heat seal, wrinkle and other phenomena. The heat seal style of BOPP cigarette film is heat-pressure seal, that is, to heat seal at certain heat seal temperature, pressure and period. The heat seal testing is to test the minimum heat seal separating force after heat sealing. It is widely applied in the cigarette industry that Labthink PARAM HST-H3 Heat Seal Tester and PARAM XLW (PC) Auto Tensile Tester are used together. The heat seal strength of cigarette is normally required to be above 2.0N/15mm. Now, with the development of cigarette packing machine, low temperature heat seal film becomes more popular, which requires the heat seal strength above 1.5N/15mm.

E. BOPP Cigarette Film Coefficient of Friction Testing

The smoothness of BOPP cigarette film is one important index for BOPP films with is the testing requirements coming along with the high speed packing.

There are four kinds of situations that need coefficient of friction testing, namely, the coefficient of friction of the film and the metal side of the machine or the transfer belt; the inside side between films; the film inner side and the cigarette outer package; and the outer film side and the outer package. Of these four coefficients of friction, the first should be low so as to better transfer the cigarette package and improve packing speed.

The inside coefficient of friction should be a bit higher than that of the outer film and the machine metal side for precise location of film and cigarette package so as to improve heat seal quality and packing effects. The coefficient of film and outer paper box should be low for smooth insertion of cigarette packages. The testing speed is 100mm/min, or 150mm/min in US Standard. Labthink PARAM MXD-02 Coefficient of Friction Tester complies with many standards including US standards and international standards, and gets wide applications. Since the reference for cigarette film coefficient of friction varies, e.g., metal panel, cigarette box, inner and outer sides of films, etc., the coefficient of friction is normally between 0.2-0.6.

F. The Heat Shrinkage Testing for BOPP Cigarette Film

BOPP film heat shrinkage is mainly used for the evaluation of heat stability under different conditions or different factors. For rigid cigarette package, such rigid package has good support effect, around which high shrinkage film can be applied so as to achieve even and beautiful visual effects. Therefore, rigid package requires the heat shrinkage of BOPP cigarette film to be up to 8% to 12%.

But, deformation cause by high shrinkage rate is a problem for ordinary flexible cigarette package. Generally, the shrinkage rate is controlled within 3%-7%. For heat shrinkage testing of BOPP cigarette film, ASTM D 2732, or GB/T 13519 is applied. Take Labthink PARAM RSY-R2 Film Free Shrink Tester as an example; mark the vertical and crosswise lines on the specimen with clear indication of direction. Put the specimen in between the frame, and immediately emerge into 120±2C constant temperature medium for 20 seconds. Then, emerge the specimen into the prepared normal temperature bath for 5 seconds, and take it out. Lay horizontally and measure the vertical and crosswise size within 30 minutes. The measurement should be with accuracy up to 1 mm. At present, some companies heats 1 minute, 5 minutes or other conditions under 120C with different testing results.

G. BOPP Cigarette Film Abrasion Resistance Testing

With stricter requirements for abrasion resistance, inferior abrasion resistance performance would greatly influence the beauty of the cigarette package. The testing of abrasion resistance is to avoid scratch on the surface of the product caused by the contact of film surface and the machine; and to avoid wounds caused by film and outer package. Labthink PARAM MCJ-01A Rub Tester can be applied for the test. Take a piece of clean offset paper of 50mm width and 80g/m2 onto the rub tester. Cut a piece of BOPP cigarette of certain size and put on the rub platform. Set the rub times and start to see the abrasion.

Above all, there are many BOPP cigarette film testing items. When testing, relevant standards must be applied; or unified testing conditions for data comparison. Labthink, is willing to have further dialogues on BOPP film and its quality with professionals of the industry.

The principle of volatile corrosion inhibition is by using VCI, volatile corrosion inhibitor which can be evaporated under normal temperature so as to achieve saturation in the closed environment; VCI molecules are absorbed onto the metal surface to form a transparent protection film of several molecules thick after complicated physical and chemical reactions. This transparent protection layer is water proof, difficult to be dissolved and thus, can stop further corrosion. Evaporated VCI molecules can reach anywhere in the package with best anti-rust performance. VCI plastic material is manufactured by polyolefin resin with VCI under processes.

Barrier property is defined as the barrier performance of packaging material against liquid or gas permeable substances. The entry of oxygen would greatly increase the possibility of oxidization of metal contents, and the water vapor barrier property is of even more importance.

For gas barrier property, Labthink introduces PERME VAC series Gas Permeability Testers and Labthink PERME OX2/230 Oxygen Transmission Rate Test System that comply with relevant ASTM, ISO or GB standards (such as GB 1038 and GB 1037). For water vapor barrier property testing, Labthink PERME TSY-T series Water Vapor Permeability Testers and Labthink PERME W3/330 Water Vapor Transmission Rate Test System are applicable.

Labthink, the excellent provider of testing instruments and testing services, is devoted to provide most excellent and complete quality control solutions for pharmaceutical, foodstuff, cosmetics, packaging, printing, adhesive, automotive, petrochemistry, environment, biology, new energy, construction, aviation and electronic industries worldwide.
