What problems should be paid attention to in powdered food packaging?
In the powder food packaging, the most important thing to pay attention to is that the electrostatic adsorption during the bagging process is that the powder adheres to the sealing part, so that it cannot be heat sealed well, causing the problem of poor heat sealing.
For example, coffee and soybean powder should be packaged with PET film with antistatic PET film. Moreover, when emphasizing the use of barrier, one side should be PVDC coated, and the other side should use antistatic PET film.
In addition, in order to improve the antistatic property, the Heat sealing layer material must also use antistatic film. This is because the static electricity cannot be completely discharged by the surface substrate alone.
