Inspection Method When Selecting Plastic Packaging Bags

Jan. 28, 2019 Share

Custom Printed Plastic Packaging Bags are one of the ways we use plastic bags. In order to ensure the quality of our products, we need to inspect them. Now let's take a closer look at this knowledge.

A good quality plastic bag will make a crisp sound when it shakes, while a poor quality plastic bag will have a small sound and be dull and low. When testing its quality, there is another way to put it in the water, it will be non-toxic, and the bottom is the toxic plastic bag. You can also put the flat mouth on the fire and burn it soon. The flame is yellow, and it flows down like a candle like a paraffin. If it is a poisonous bag, it is hard to burn. The flames that are emitted are green and give off a horrible taste.

Qualified Plastic Stand Up Pouch Bags are strong and strong, and are not easily torn off. Unqualified bags are not strong enough to be broken due to the addition of harmful substances.
