For coordination with the relevant person in charge of the national standard committee recently said the notice requirements of the state council, the standards committee at the end of last year has launched the standards set by the research work related plastic shopping bags, at present the standard work plan has been fully launched. The standards are expected to be published by the end of this month.

It is understood that there is no specific standard for plastic shopping bags, and there is no product standard that is less than 0.025mm plastic shopping bag.

In appearance, the plastic bag is required to be uniform and smooth, no wrinkles, no scum, no stains, no bubbles, no color holes.
Consumers can often see poor plastic bags with blurred text patterns on them. The new standard will require that the printing quality of plastic bags must be even with ink, the pattern should be clear and complete, the printing accuracy shall not be greater than 1mm.
