FLAME TREATMENT APPLICATION

Industrial process used to improve

wetting and adhesion properties

of polyolefin films :

BOPP Bioriented Polypropylene

OPP Oriented Polypropylene

PE

PET

PS

automotive 3D plastic components as :

bumpers

dashboards

 

and

other special application as:

flame treatment for assemby of headlight bodies

surface flame treatment on blow- molded plastic bottles

 

Main process, it consists, on flame running,

against the surface of the material, to be treated.

Such surface, could be modified in terms of energy and surface tension,

so improving wettability to prepare it

for next applications as printing, painting, coating, lacquering.

COSMETIC AND IGENIC CONTENITORS FLAME TREATMENT AREAS OF USE FLAME TREATMENT AREAS OF USE

Polyolefin materials, and in particular PP polypropylene have many properties / advantages as:

  • low cost

  • can be worked and shaped quite easily

  • can get good mechanical properties, if properly worked

  • are very good electric insulators

Anyway they are ‘ apolar ‘ on their surfaces, ( poor surface energy).

This is the reason why they need to be treated, in order to make possible their coating with inks, paints, adhesives, metal,

and other materials typically coupled with polyolefins, in industrial applications as flexible packaging or automotive production 3D parts.

FLAME TREATERS COMPONENT MACHINERY

A typical flame treatment plant installed in a BOPP line – basically – is composed of the following units:

1.  Burner (water cooled), that produces a suitable flame for web surface treating.

2. Treater roll (water cooled), that supports the web, by cooling it under the flame passage, and by allowing in this way , prevention on overheating dameges, on film surface.

3. Nip roll (suitably rubbered), having the duty to eliminate air layers/blisters between film surface and treater roll, that could compromise the right thermal exchange.

FLAME TREATMENT PROCESS VARIABLES

A) Mixture flow

B) Mixture composition – Air/Gas ratio

C) Air Gap

D) Treater roll temperature
