Q: The difference between a vacuum and a vacuum in a food package: So, the difference is very clear, is the vacuum packaging bag of the air as much as possible out, but the inflation is the air in the bag is replaced by nitrogen or carbon dioxide and other inert gases, the purpose is as far as possible to reduce food and air contact oxidation process, slow food, avoid food rapid deterioration.

Material or process technology?: On the basic price will be a little higher, the brittle is generally PP or PET is done, some relatively low grade. Soft is generally made of multi-layer coextrusion film, barrier, and feel good. This soft about 27000 yuan / ton, while the PP film generally as long as 17000 yuan / ton, ten thousand tons a difference.

Q: Why are some teas not vacuum packed?: Some tea leaves are not allowed to be packed in vacuum, such as crunchy and fragile tea leaves, easily caking tea leaves, easily deformed tea leaves, sharp edges and corners or higher hardness, and will puncture the tea bags and so on. For example, Yunnan tea, are generally made of tea or tea brick, covering the surface of a layer of paper for simple packaging.

Q: What does "13 silk" in vacuum packing bag mean?: The vacuum packing bag 13 silk refers to the vacuum packing bag's thickness is 0.13 millimeters.

Q: Printing solvent for food packing bag: Determine the amount of water in the solvent by means of the principle of a different dissolution effect. Take the most transparent glass cylinder tube with 100ml toluene solution, take a small amount of analyte ester solvent such as toluene, evenly pour. When you just pour in toluene, carefully observe whether there is turbidity (milk white) phenomenon. If there is this phenomenon, the water content of the solvent is seriously exceeded, and the experience shows that when the moisture content exceeds 0.5%, the phenomenon is obvious. The water content test of benzene solvent can be carried out by extracting solvent from the long glass tube to observe whether there is delamination.
