01 / Coil Consolidation
Temporary pressure around wound constructions
The heat-shrink film or tape surrounds the construction and applies temporary inward pressure during the confirmed cure cycle.
Polyester Process Film / ATR-PET-HS
Polyester Heat-Shrinkable Film
An oriented PET process film used to provide controlled temporary consolidation pressure during the confirmed curing process.
How It Works
A temporary process film shaped by the cure cycle.
The film is selected as part of the customer's complete winding, curing and removal process. Final shrink behavior and suitability must be confirmed under actual conditions.
- 01
Wrap
The film or slit tape is applied around the construction in the confirmed winding format.
- 02
Heat
During the confirmed curing cycle, the oriented PET film shrinks in the machine direction.
- 03
Consolidate
Shrink tension provides temporary compaction around the wrapped construction during cure.
- 04
Release
Where a release-coated format is selected, the process wrap can be removed after cooling and cure.
Typical Process Uses

Each illustration explains a different process role. It does not represent a universal construction or publish unconfirmed technical values.
02 / Composite Processing
Uniform compaction around a mandrel
A slit heat-shrink tape can follow a continuous helical path around a laminate to support consolidation during cure.
03 / Controlled Venting
Compaction with an optional venting route
Standard or perforated formats are selected according to the required process route and must be validated with the complete resin system.
04 / Post-Cure Removal
Release-coated process wrap
A confirmed release-coated construction supports removal after heat cure and cooling; it is a temporary process wrap rather than permanent electrical insulation.
Available Forms
Roll geometry prepared around the process.
Master rolls, pad rolls and multi-roll formats are supplied according to the confirmed width, core I.D., roll O.D. and roll length requirements.
