With the development of society, packaging bags and articles are no longer rare, and can be seen almost everywhere in life. Especially in recent years, the rise and prosperity of the food industry, to a certain extent, has also led to the food packaging bag processing and manufacturing industry. With the continuous growth and reform of the market, there are now thousands of packaging manufacturers in the manufacturing and marketing of it.

1. In order to ensure correct scanning and reading, the barcodes printed in plastic packaging bags should be neat and clear, and the barcodes should not be obviously incomplete, and there should be no redundant black spots in the blanks. Usually, the large diameter of the defects and stains should be no more than 0.4 times of the nominal narrow barcodes.

2. Controlling the size error of barcode is the guarantee to improve the reading rate of reading device and reduce the decoding error rate. This requires not only improving the quality requirements of plate making, printing or printing, but also improving the tolerance requirements of reading device.

3. In order to read reliably, bars and spaces in printed barcodes should have obvious contrast signals. The bigger the contrast signals of barcodes, the better their reading performance.

4. Printing tolerance must be strictly controlled, otherwise the effect of reading will be affected.

5. There are certain requirements for the edge roughness of the barcode of plastic packaging bags. When the roughness is too large, it can not be read.

Our manufacturer has rich experience in manufacturing this kind of packaging bags. All the selected materials are approved by the state, which can ensure that they will not pose a threat to human health. They can also degrade in a certain period of time and protect the environment as much as possible. These are in line with our country's call for energy conservation and emission reduction.

Not only that, our packaging manufacturers have a certain time base in the sale of food packaging bags, with a stable source of customers. Nevertheless, we will not reduce the quality requirements of packaging bags. On the contrary, it will supervise the work of factories more strictly and accomplish the production tasks with high quality and quantity.
