For Packaging Testing

Definition: A property of paper referring to the degree to which a paper can maintain its surface and structural integrity under prolonged rubbing, scratching, and scuffing The term abrasion resistance also refers to a printing ink's ability to resist scuffing and scratching with increased handling, an important consideration in the printing of packaging and other materials destined to be subjected to abrasive forces.

Device description : The abrasion tester is a robust instrument suitable for table top use . the accurate control and driving elements are contained in study aluminum housing with durable baked wrinkle enamel finish . The operating data , such as number of test cycles and vacuum rate , are entered by way of control panel with keyboard . A digital display shows reading of the either current abrasion cycles rate (wear index) or the remaining number of abrasion cycles. By using the abrasion tester , two abrasion sets with different specified parameters can be conducted simultaneously , yet remaining independent of each other . the instrument enables abrasion testing on paint and other coatings , such as paper , leather , ceramics , textile surface structures and metals . the equipment is suitable for use in research and development for in-process and quality assurance controls

Test Description: Abrasion resistance is measured in a laboratory by rotating a paper sample under abrasive wheels for a set length of time, and then measuring the sample's change in weight. Wet or dry abrasion resistance tests can be performed. The wearing action is caused by two abrasive wheels , which are applied at a defined pressure to material sample , which has been mounted on a rotating specimen holder . abrasion resistance can be established by various testing methods (weight loss method , visual end point method , depth of wear method etc.)

Device Description : The metering bar coater is a table top instrument with a quick clamping unit for the sample . the coating materials (like a piece of paper and board) lies on a rubber – melinex surface . A metering bar is clamped into a clamp system and the coating colour is put on front of the bar . the motor moves the bar with a predefined speed over the coating material and stops when the end is reached . the bar is lifted off the coated samples and motor moves the system back to start position.

Test Description : The sample us clampled on the coater . A metering bar is slected and put into the bar holder . the bar is at starting position. The coating colour is poured onto the coated materials in front of the bar . the motor starts and the coated colour is evenly distributed on the sample . the coating thickness can be between 4um and 120um and is reached by selecting the special metering bar.

Definition : The water absorbency of paper (the cobb value) is defined as the quantity of water absorbed in a given time by one side of a unit area of paper or board placed horizontally under a head of one centimeter of water.

Standardization : ISO 535 , TAPPI T441 , SCAN P12, EN 20535, DIN 53132

Device Description : for the determination of the water absorption of sized paper and board , including fiberboard under standard conditions . A test piece is weighed immediately before and immediately after exposure one of the surface of the water for specified time , followed by blotting.

Definition : Rigidity of the fluted structure is one of the essential characteristics of corrugated board and flat crush resistance is necessary to prevent crushing of the flute structure on the corrugator and other converting equipment. The corrugating medium test (CMT) permits the evaluation of corrugating medium before it is fabricated into combined board, and may also be used as a basis for judgement of fabrication efficiency.

The sample is glued on a tape with the help of a “Third Hand” and is then ready for testing in a crush tester.

Test Description : the sample is put into the opening on the top of the instrument . by pressing the start button , the stripe with 6”x ½” (152.4 x 12.7 mm) dimesion is inserted into the machine and falls out ready formed on the lower part . the sample is then laid onto the opened “Third Hand” the holder is closed and the tape is glued onto the sample . this sample is now ready for testing.

Device Description : the Burst Tester is built on a sturdy aluminum frame and the results are displayed on a digital load indicator . the Burst tester works according to Mullen principle . A piston pumps glycerin under the circular elastic diaphragm. The diaphragm bulges and distorts the sample, which is clamped around the periphery around the clamping bell. Pressure is increased until the sample is burst.

Test Description : It is measured by giving a hydraulic pressure through a rubber diaphragm on a circular area of the specimen of CBF under test conditions. Force requires to burst or complete rupture of the Paper/ board is measured visually. The bursting strength value is expressed in terms of kgs/cm2. The bursting strength defines the materials quality compare to the others. The value of the bursting strength will give the indication that how much weight may be carried in the Paper/box.
