A layer in the duct wall
Metallized PET is used in multilayer flexible-duct constructions, where the film may be combined with other laminates, wire support, insulation, or an outer jacket.
APPLICATION FIELD · Application
Flexible Duct
Metallized PET film for flexible HVAC duct laminates, discussed as one layer in a duct construction with its own reinforcement, jacket, joining, and compliance requirements.

PROJECT NOTES
Application information supplied by the buyer or converter.
Aluminized laminates for air-duct insulation — radiant reflectivity with tear resistance.
Tell us your converting line and we will match a metallized film grade to it.
WHAT MATTERS IN THE MATERIAL BRIEF
Turn end-use requirements into a clearer film discussion.
Forming and lamination fit
Film selection should consider the duct maker’s adhesive, reinforcement, forming sequence, slit width, and handling conditions.
Duct-level evaluation
Air leakage, temperature range, flame or smoke requirements, mechanical durability, and pressure performance belong to the finished duct specification and test plan.
TYPICAL APPLICATION CONTEXTS
Where this type of metallized film is commonly considered.
These examples describe common finished-product contexts. The appropriate film construction still depends on the complete layer stack, conversion route, and required evaluation.
Flexible HVAC air ducts
Multilayer duct cores and covers used in air-conditioning and ventilation systems.
Insulated flexible duct products
Duct constructions that combine a flexible inner core with insulation and an outer jacket.
Ventilation connectors and duct components
Flexible air-handling constructions where the converter defines the reinforcement, laminate build, and finished dimensions.
FILM ROLE IN THE FINISHED STRUCTURE
Specify the film for the duct build, not in isolation.
Metallized PET is commonly used within flexible duct laminates because it can contribute a metallized surface while the completed duct obtains its form and final properties from the full multilayer construction. The film is not a substitute for the wire helix, reinforcing layers, jacket, or joining design.
The most useful request identifies the finished duct type, layer stack, processing route, width, and the markets where the duct will be installed. That allows the material conversation to stay aligned with the converter’s actual build and test procedure.
