It may be the ozone generated by the ultraviolet curing lamp. Generally, self-adhesive printing factories do not cause much pollution. Except for gravure printing factories that print plastics, most printing factories do not pollute very much:

Air pollutants:

Traditional lithographic offset printing: odor of dry ink volatiles, cleaning fluid (gasoline smell) odor, material odor

UV lithographic offset printing: ozone odor, cleaning Liquid smell, ink smell, material

Toppan printing: ozone smell, cleaning liquid smell, ink smell, material

Screen printing: ink drying volatile smell, cleaning liquid (banana water) ) smell, material smell

UV screen printing: ozone smell, cleaning liquid smell, ink smell, material

Flexographic ink printing: material smell, other smells are very clear

Flexographic UV printing: ozone odor, materials

General self-adhesive printing uses a variety of printing technologies, but gravure printing technology is rarely used

Pungent smell There are 2 possibilities:

1. The fishy smell of ozone produced by the ultraviolet curing lamp: the smell is the largest in the same printing format>uv screen printing>uv embossed printing>uv offset printing

2. Ink And the smell of cleaning agent: the same printing format has the biggest smell>Screen printing needs to be dried>Natural drying screen printing>Offset printing

It is found in traditional offset printing and natural drying screen printing and does not require a special exhaust duct system. The home that is most likely to produce odors has such equipment;

1. Full-rotation or semi-rotation UV letterpress label printing machine

2. Rotary UV or hot air drying silk Screen printing machine (the most flavorful)

3. Small offset printing machine

If there is such equipment, generally such a factory needs to work 24 hours and 3 shifts to make money, you can Join forces and call the police when they start work at night, sue them for noise nuisance and prevent them from working at night. If they often miss work deadlines, they will naturally move out. If they never work at night, let me tell you, they are just little daddies. Factory, pollution may not be as big as the snack bar downstairs in your home! In addition, it is very likely that they are engaged in other processing, such as plastics or chemical products. It is best to find an insider to find out!
