Information

Printing food bags can be said to be popular in the current market, mainly because they play an important role in the food industry, and can even be said to be irreplaceable products in a short time and become an indispensable necessity in the food industry. The quality of printing food bag directly affects the product, it is accompanied by the entire process of food production and circulation. So how to judge whether the printing food bag is qualified? The editor of the packaging factory will analyze it with you for your judgment.

Printing food bags

1. The appearance of qualified printing food bag has no defects such as bubbles and perforations. And the deviation of width and length is within a certain range. Exceeding or defective packaging bags are considered unqualified.

2. The physical and mechanical properties of printing food bag production process include tensile strength and elongation at break, which reflect the ability of the product to withstand tensile stress during use. If this item is unqualified, the food packaging bag (film) is easy to crack and damage during use.

3. Unqualified printing food bags can detect substances harmful to human health, such as heavy metals, residues, etc. At the same time, the residues will also affect the quality of food, such as color, aroma, taste, etc. Such food packaging bags are often harmful to the human body. Qualified food packaging bags often need to have a certain degree of hygiene in order to ensure the quality of food. Therefore, manufacturers of customized food packaging bags must conduct on-site inspections of the packaging plants before placing orders to ensure their safety and hygiene.

4. Biodegradable packaging can be divided into photodegradable type, biodegradable type and environmentally degradable type according to the different types of product degradation. The degradation performance reflects the ability of printing food bag products to be accepted by the environment after use and disposal. If the degradation performance is good, the bag will be broken, differentiated and degraded by itself under the combined action of light and microorganisms, and finally turned into debris, which will be accepted by the natural environment. If the degradability is not good, it will not be accepted by the environment and cause environmental pollution.
