Static Problems with Thermal Plastic Overwrap

Prevent cling on frames/rollers and help film form properly around the product

Problem:

A high static charge is built up as the film unwinds and passes over various machine parts, rollers, and web guides. This can cause the film to stick to the machine frame, rollers, or itself instead of forming around the product.

Solution:

Install a 915 Ionizing Bar at point “A” (see diagram) to prevent the film from wrapping around rollers.

If the film is not forming around the product properly and is sticking to itself or the machine frame, install a second 915 Ionizing Bar at point “B”.
