Determination of transparency of small food packaging materials[ 2018-07-20 ]
Test procedures: 1. According to the test sample requirements of the transmittance fog tester, cut the test sample 2. After the instrument is calibrated, install the sample, press the test button, and soon the transmittance and fog values will be displayed on the screen. 3. When the retest is needed, the sample cannot be taken off. Multiple tests can be obtained by pressing the test button again, and then the arithmetic average value of the test is taken as the test result to improve the accu

Such as: hanging card envelope bag, with the card head and the envelope mouth, the envelope mouth is the place of glue. The hanging card has a flat pocket with a card head and no envelope opening. The bottom is flat. Seal in the back middle bag/pillow bag Usage: it is used for shaver, all ki
The reasons and the solutions of poor transparency of composite packaging film[ 2018-07-02 ]
Reason: 1. The surface temperature of the cooling roller is too high 2. The surface is too rough 3. The pressure of compound roller is insufficient 4. The initial adhesive force of AC agent is poor. Solution: 1. Decreasing temperature properly. 2. Replace with a clean cooling roll 3. Increase compound pressure 4. Use a high viscosity AC agent 5. Adjust the extrusion process parameters
Three ways to determine a high quality aluminum foil bag[ 2018-06-25 ]
1. Appearance, the surface of aluminum plating shall be clean, bright and smooth, without lamination and crack indentation. 2. Degreasing. Aluminum foil bags for composite packaging shall have an oil pollution grade of AB. Test method is as follows: Put aluminum foil samples without stain and wreck at 45 degrees on the plate, drop test solution in the middle of the sample on both sides, who is not a bead and spread of namely the level standard. A: Test with distilled water B: Test with distil
