Key Point of Breathable Membrane Car Perfume Production

Key Factors in Producing Membrane Air Freshener Car Perfume

The production of a Membrane Air Freshener (car perfume) relies on precise control of fragrance release, stability, and safety, while also considering user experience and environmental requirements. Below are the core production considerations:

1. Selection and Optimization of Membrane Material

• Semi-permeable Membrane Properties:

• Must have controlled breathability to ensure even fragrance release (typically lasting 30–60 days).

• Must withstand high temperatures (up to 60°C+ inside cars) and low temperatures (-20°C) without deformation or cracking.

• Common materials: Microporous PE/PP film, TPU (thermoplastic polyurethane), silicone membrane, etc.

• Pore Size Control: Adjust the porosity (nanoscale micropores) to regulate fragrance diffusion speed.

2. Fragrance Formulation Design

• High-Concentration, Slow-Release Fragrance:

• Requires low-volatility (low VOC) fragrances to prevent rapid evaporation or overpowering scents.

• Must resist oxidation to avoid degradation under high heat (e.g., citrus notes oxidize faster, while woody notes are more stable).

• Solvent Compatibility:

• If using liquid perfume, solvents (e.g., DPG, TEC) must be compatible with the membrane to prevent corrosion or swelling.

3. Structural Design and Encapsulation

• Liquid Reservoir and Membrane Sealing:

• Liquid perfumes require airtight sealing to prevent leakage (heat sealing).

• Gel-based versions must ensure strong adhesion between the membrane and base material .

• Anti-Leakage Design: Prevents spillage during bumps (e.g., using a one-way permeable membrane).

• The combination of packaging materials and sealing temperature is the key.
  

4. Release Rate Control

• Temperature Compensation Technology:

• High temperatures expand membrane pores, but material modifications (e.g., adding temperature-sensitive polymers) can balance evaporation speed.

• Multi-Layer Membrane Structure:

• Outer controlled-release layer + inner buffer layer for stable diffusion (e.g., 3M patented technology).

5. Safety and Environmental Considerations

• Non-Toxic Certification: Complies with IFRA, REACH, RoHS standards, avoiding harmful substances like phthalates.

• Flame Resistance: Membrane materials must pass FMVSS 302 automotive interior flammability tests.

• Biodegradable Materials: Such as PLA (polylactic acid) membranes to reduce environmental impact.

6. User Experience Optimization

• Adjustable Fragrance Intensity:

• Some designs feature adjustable membrane flaps or multi-level vent settings for scent control.

• Compact and Discreet Design:

• Fits car air vents, cup holders, etc. (e.g., magnetic or clip-on mounting).

• Residue-Free Installation: Avoids adhesive marks (uses silicone suction cups or 3M removable tape).

7. Packaging equipment

Influence of Different Packaging Equipment on Sales Volume

Horizontal filling and vertical filling, these two different filling and packaging processes also affect the market acceptance of automobile perfume to a certain extent.Usually, vertical filling machines are more popular with consumers because of their larger filling capacity.However, horizontal filling is favored by small factories because of the lower price of equipment.

Secondly, different vertical filling machines are very different in the aesthetic degree of packaging, so we must pay attention to it when purchasing.
