Wrapping & Contamination Problems with Bottle Overwrapper

Common electrostatic pain points on web-based overwrapper machines—and how to neutralize them.

Problem

There are three areas of concern with this type of packaging machine:

  • Dust attraction during unwinding of the web.
  • Electrostatic attraction of the web to the cutting knife and vacuum transfer belt.
  • Electrostatic attraction of the sheet to itself during overwrapping.

Solution

  • Use a Meech 935 ionising blower to control charges on both unwinding rolls.
  • Install a Meech 915 bar to neutralize charges on the web before entry to the sheeting knife area.
  • Add a Meech 971 bar to prevent electrostatic charges from pulling sheets out from under the containers being wrapped.
