Curing for more than 4 hours, in order to make the food packaging bag not easy to delaminate. The sixth step: bag making At this time, the production of food packaging bags has come to an end. The bag making technicians need to have certain skills. They must ensure that the edges of the color […]

Food packaging bag material composition and performance profile Due to the limitations of a single material, so far, most food packaging bags using two or more layers of composite materials. The scientific and reasonable use of multi-layer materials composite or with, can produce different comprehensive performance, can meet the packaging requirements of almost all kinds of food. Here, the professional production of […]

Printing suitability of common food packaging bag materialsPEThe film ink adhesion is poor and needs to be treated with electricity to improve. The index of wetting tension is often used to identify the quality of corona treatment. threeLDPE,LLDPEfilm in38~420mN/m,HDPEfilm in40~44mN/mPreferably, polyamide inks are commonly used for printing.LDPEThe expansion strength of the film is low, the […]
