Reasons for the poor appearance of food bags and solutions!

The method of manufacturing high-grade flexible packaging composite packaging material when the food bag is compounded is the most widely used, the largest output and the highest quality production method. Because it involves the substrate, but also involves ink, glue, equipment, climate and many other issues, there are often problems!

Causes: 1. The upper adhesive tape is uniform and there are gravure marks. 2. Excessive amount of glue 3. The surface of the substrate has poor lubricity. 4. Conveyor film guide roller has impurities 5. There are debris or damage on the scraper, resulting in scratch marks 6. Winding tension is large, film wrinkles 7. Environmental humidity is high or water is trapped during processing, and there is no drain between layers. CO2, which produces whitening.

Solution: 1. Adjust the viscosity, concentration and blade angle of the material and replace the gravure roll. 2. Reset the coating amount or replace the roller. 3. Increase the temperature of the composite roller. 4. Clean the guide roller. 5. Clean or grind the scraper. 6. Adjust the winding tension and speed. 7. Increase the drying temperature and reduce the ambient humidity.

ISO Standard Mass Flow Meter

Zhejiang Sealand Technology Co., Ltd. is a trustworthy manufacturer of Mass Flow Meter Coriolis, Flow Meter Coriolis, Mass Flowmeter Coriolis, Mass Meter Coriolis, Meter Coriolis, Flowmeter Coriolis, ISO/ IEC 17025 standard.

Sealand meter is certified by Zhejiang Institute of Metrology. To get such certificate, Sealand has to send all models to Zhejiang Institute of Metrology and all models are tested in their calibration lab. The lab is an ISO/IEC 17025:2005 standard lab approved by CNAS (China National Accreditation Service for Conformity Assessment). CNAS is a member of ILAC (International Laboratory Accreditation Cooperation).

Besides, Sealand has its own calibration lab, equipped with METTLER TOLEDO scales with accuracy 0.014% and the device extended uncertainty is 0.05%. The lab is also approved by Zhejiang Institute of Metrology. This certificate will stay valid only for one year, Zhejiang Institute of Metrology will send their professor to Sealand every year to check and make sure that the lab is qualified still and then issue new certificate. During the production, each meter will be calibrated in this lab for 3 times, each time at 5 different flow rate.
