AromaFlow™ – Breathable Laminate for Fragrance and Aroma Sachets

Kae Hwa’s AromaFlow™, part of the FunPack series, is a highly engineered breathable film laminate designed specifically for premium fragrance pouches, scented beads, and essential oil sachets. By providing a precise Moisture Vapor Transmission Rate (MVTR), AromaFlow™ ensures a steady, long-lasting release of aromas while completely blocking liquid oils and preventing chemical seepage, making it the perfect packaging solution for the home and car fragrance industry.

AromaFlow™

Breathable Material for Controlled Fragrance Release

AromaFlow breathable material for controlled fragrance release

AromaFlow™ is a breathable functional packaging material developed for fragrance sachets, aroma bags, deodorizing packs, and scented lifestyle products requiring controlled fragrance diffusion.

Its engineered breathable structure allows fragrance vapor to move gradually through the packaging material instead of being released all at once, helping create a more controlled and consistent aroma experience.

Combined with a printable nonwoven surface and stable sealing performance, AromaFlow™ gives fragrance brands and packaging manufacturers a flexible platform for combining scent release, protection, appearance, and converting efficiency.

Controlled Aroma Release Printable Surface Seal-Friendly

Engineered for Gradual and Consistent Fragrance Diffusion

Fragrance packaging must allow aromatic molecules to reach the surrounding environment without exposing the contents too rapidly. If permeability is too high, fragrance can dissipate quickly. If the structure is too restrictive, the scent may remain trapped inside the package. AromaFlow™ is engineered to provide a controlled interface between the fragrance formulation and the surrounding air.

Controlled Fragrance Diffusion

Breathable pathways allow fragrance vapor to gradually move through the material for a more balanced release profile.

Content Containment

The laminated structure helps keep fragrance beads, powders, activated carbon, and other internal materials securely contained.

Brand-Friendly Surface

Printable nonwoven surfaces support decorative patterns, logos, fragrance identities, instructions, and customized graphics.

Reliable Sealing

Designed to support clean package edges and compatibility with thermal or ultrasonic sealing processes.

Core Advantages

Controlled Aroma Release Engineered permeability helps regulate the rate at which fragrance vapor reaches the surrounding environment.
Breathable Microporous Structure Microscale pathways create a controlled route for fragrance vapor while maintaining an enclosed packaging structure.
Soft & Flexible Surface The nonwoven laminate provides a soft, fabric-like feel suitable for wardrobe, drawer, gift, and lifestyle fragrance products.
Decorative Printability Surface printing allows fragrance packaging to become part of the product's visual identity instead of functioning only as a technical barrier.

How AromaFlow™ Works

AromaFlow™ creates a controlled diffusion pathway between the fragrance material inside the sachet and the surrounding environment.

1

Fragrance Vapor Develops Inside

Aromatic compounds released from fragrance beads, powders, scented carriers, or other formulations accumulate inside the package.

2

Vapor Diffuses Through the Material

Engineered breathable pathways allow fragrance molecules to move gradually through the laminate instead of escaping through an open package.

3

Aroma Is Released to the Environment

The fragrance disperses into wardrobes, drawers, vehicle interiors, footwear storage, or other enclosed spaces while the solid contents remain inside the sachet.

AromaFlow™ Functional Principle

“Allow fragrance to diffuse gradually while helping keep the fragrance carrier securely contained.”

Application Fit

Fragrance Sachets Breathable packaging for scented beads, powders, mineral carriers, dried botanicals, and similar aroma products.

Redefining the Boundaries of Breathable Technology

Understanding Aroma Diffusion — The Benchmark for Premium Fragrance Packaging

For a fragrance sachet to be successful, it must deliver a consistent olfactory experience from day one to day thirty. Materials like standard paper or basic nonwovens allow scent to escape too quickly and offer no liquid barrier. AromaFlow™ uses engineered micropores that act as a strict gateway. They are large enough to let volatile fragrance molecules diffuse into the room, but completely impermeable to the liquid essential oils inside, setting the benchmark for both performance and consumer safety.

FAQ

Our laminate features a highly engineered microporous film. While the microscopic pores allow volatile scent molecules to evaporate into the air, the film's structural surface tension completely blocks liquid essential oils and gels from passing through, ensuring zero leakage and zero stains.

Not at all. We utilize a highly advanced solvent-free lamination process. Unlike older methods that use chemical adhesives which can release foul odors (VOCs) and ruin your perfume's profile, our material is completely odorless and neutral, preserving the exact scent you designed.

Yes. By fine-tuning our Casting Film Technology, we can customize the Moisture Vapor Transmission Rate (MVTR) and pore size. This allows us to create a material that releases the aroma slowly over several months, or more rapidly for an intense, short-term fragrance experience, depending on your product's requirements.
