Packaging test equipment: What needs to be done for base paper, cardboard, and carton

Dongguan Haida Instrument specializes in the production and sales of carton presses, bursting strength testers, vibration testers, drop test benches, and ring press testers. We welcome new and old customers to inquire 400-071-1808/0769-89280808 .

1. Moisture Test (Moisture Tester) This test is the most common one. Whether it is raw materials or ready-made finished products should be tested for moisture, because the raw materials are purchased according to the weight. Therefore, the content of water directly affects the cost of the company. For printing, it is necessary to test the moisture of the product after printing so that excessive moisture accumulation will cause mildew. If it is a cardboard box, excessive moisture will stress the carton's resistance to stress.

2. Bursting strength test (breaking strength tester) is mainly used to test the bursting resistance of white paper, gray paper, cardboard, etc. The purpose is to test the firmness of the product in the future use process. . A total of 12 samples were taken without print marks, creases, or significant damage. Sample clamp pressure: >690kpa (adjustable) equivalent to 7kg

3. Ring pressure tester (side ring compression strength tester) pressure test, in terms of corrugated board, is commonly used to pull, flat pressure, side pressure, glue, bending and other tests. The most used is the side pressure, and its principle is to take 3 pieces of the specification from the carton or cardboard to be 100mm*25mm, no printing, no mechanical indentation. A total of 9 pieces of damaged samples were divided into three groups for testing, and finally the average value was taken out.

The strength of the side pressure can be calculated according to the following formula

R=F×103÷L

Wherein: R-side pressure intensity unit N/m;

F-sample maximum force N;

L-sample long dimension mm.

In addition, for papers with a thickness of no more than 1.0mm, the pressure test is a ring pressure test. The test principle is to cut a 152mm*12.7mm strip of paper and then place the specimen in a ring pressure test fixture. In the stress test. As shown below:

The machine senses with a high-precision sensor and displays the strength digitally through software analysis. It is used for corrugated paper and kraft paper tapes with a thickness less than 1mm. The sample is placed in the container of the ring plate, and its erection is checked by the machine. The direction of the pressure strength, with a variety of accessories to use, and can test the vertical cardboard strength, bonding strength and flat compressive strength.

4. Bending machine: (flex-breaking tester) This machine is specially designed to test the folding strength of paper and paperboard. The test method is to fix the two ends of the test piece on the machine and the lower jig and apply a certain weight to the test piece. A certain tension. Under the vertical state of the test piece, the lower jig is reciprocally bent to the left and right sides until the test piece is broken and the value of the bending times is recorded.

5. Ink Abrasion Tester: (Ink Decoloration Tester) This machine is used to test the adhesion and firmness of the ink to determine the quality of the ink. This machine can do dry grinding test, wet grinding test, decoloring change test, paper fuzzy test and special grinding test. The Ink Abrasion Test is a specially designed test method for evaluating the abrasion or abrasion resistance of ink on paper or cardboard.

6. Constant temperature and humidity meter: (Constant temperature and humidity box) This machine uses high stability platinum PT-100 temperature resistance body, LCD Chinese and English touch / touch screen, with multiple PID control functions, equipped with RS- 232C/485C with computer interface control, comparable to high temperature and humidity / high temperature / low humidity / low temperature / high humidity / high temperature / low temperature and other different environmental conditions, but also with a high degree of ease of operation and learning programming control and fixed-point control system , provide the best test performance. Widely used in industries such as electronics, military, plastic, hardware, chemical, paper printing ink and other industries, such as: electronic components, automotive parts, notebooks and other products virtual climate environment testing.

For the printing and packaging industry, this test is mainly to observe the changes in the performance of the carton in various aspects of climate and temperature. Such as sealing adhesive tape is rolled up, printing color is faded and so on. This test is intended to test the heat and moisture resistance, sweat resistance, and low temperature resistance of materials and finished products.

7. Carton compression tester: (carton compression tester) is controlled by a calculator and has high precision. It is the most direct test instrument for checking the compressive strength of cartons or other packaging containers. It is used to determine the compression resistance of cartons, and Do test holding stacking code. The results of the test can be used as an important reference for the height of the finished product container stacking. The operation settings are all handled by the dialog box of Windows, the self-planning table mode, the test data can be directly called in the main screen, and the function with automatic magnification, to achieve the most appropriate size of the graphics, can be compared with multiple curves at the same time Can choose to translate, overlap, data, with a variety of unit functions metric system, English system can be set, with automatic back to back function, with automatic correction function, full Chinese culture and other barrier-free version of the program without language barriers ( There is also English). Design standard: TAPPI-T804 JIS-Z0212.

8. Resistance to yellow aging instrument: (yellowing resistance aging tester) Yellowing resistance and aging test, in the printing industry, it is generally to test the yellowing resistance of inks and papers and their aging degree, and the resistance to yellowness is within 70 degrees of the instrument. A test of 1 hour is equivalent to 6 months in nature.
