Why choose PS plastic sheet for perfume bottle packaging?

May 15, 2025

Core advantages of PS plastic sheet

Features	Adaptability to perfume packaging	Compared with other materials (such as PP/PET)
High transparency	Transmittance> 90%, perfectly displaying the exquisite design of perfume bottles and enhancing shelf appeal.	Better than PP (translucent), close to PET but lower cost.
Rigidity strength	High compressive strength (50-80MPa), protecting glass bottles from vibration and shattering during transportation.	Harder than PE/PP, avoiding deformation of the lining and displacement of the bottle.
Easy processing	Low heat deformation temperature (70-90℃), fast blister molding (3-5 seconds/mold), and good yield> 95%.	Easier to mold than PET, and energy consumption is reduced by 30%.
Cost-effectiveness	The price of raw materials is 20%-30% lower than that of PET, which is suitable for mass production (such as luxury groups need millions of liners per year).	The overall cost is only 60% of PVC, and it is more environmentally friendly.
Chemical inertness	Does not react with alcohol-based perfumes to avoid contamination of contents (FDA/EC food contact certification).	Better than PVC (may release plasticizers).

Deep adaptation of industry application scenarios

Protective design requirements

Buffer structure: Customize honeycomb or wavy linings through thermoforming process to disperse external impact forces (such as L’Oreal Group uses PS lining to reduce transportation damage rate to <0.5%).

Anti-scratch: PS surface hardness (Rockwell hardness M65-80) prevents scratches caused by friction between the bottle and the packaging box.

High-end brand presentation

Glossiness: PS reaches 85-90 GU (gloss unit) without treatment, and can be further improved to a mirror effect through coating (such as Dior J’adore perfume lining).

Customized modeling: supports complex geometric shapes (such as arc grooves to fix special-shaped bottles), and the design freedom is higher than pulp molding.

Environmental compliance trend

Recyclability: PS classification is marked as “6”, which is compatible with mainstream recycling channels and meets the “2025 Sustainable Packaging” goal of LVMH and other groups.

Lightweight: 1mm thick PS lining weighs only 15-20g, which is 50% lighter than traditional EVA foam and reduces logistics carbon emissions.

Key points for process realization

Sheet thickness selection

0.5-1.0mm: suitable for 30-100ml standard glass bottles (such as Chanel N°5).
1.2-2.0mm: for heavy bottles or multi-layer nesting designs (such as Baccarat crystal perfume sets).

Thermoforming technology optimization

Mold accuracy: ±0.1mm tolerance ensures accurate positioning of the bottle body (avoid shaking).
Demolding slope: Design a 1°-2° bevel to prevent thin-walled PS from sticking to the mold after cooling.

Surface treatment process

Antistatic coating: Reduce dust absorption (especially for matte bottle packaging).
Flocking attachment: Local flocking enhances the luxurious touch (such as Tom Ford’s private perfume series).

Limitations of alternative materials

Material	Problem	PS solution
PET	High cost, higher molding temperature (120-150℃)	PS has the same transparency, and energy consumption is reduced by 25%.
PP	Insufficient rigidity, easy deformation, resulting in tilting of the bottle	PS compressive strength is increased by 2 times.
EVA foam	Opaque, difficult to display products; difficult to recycle	PS is 100% recyclable and has better visual performance.
Pulp molding	Easy to soften when exposed to liquids, not suitable for perfumes with high alcohol content	PS is completely resistant to alcohol penetration.

PS plastic sheet has become the preferred material for perfume bottle lining with its comprehensive advantages of high transparency, strong protection, low cost and easy recycling. Future trends will focus on:

Development of bio-based PS: such as the renewable styrene monomer technology launched by TotalEnergies.
Thin-wall lightweighting: Reducing the thickness to 0.3mm without losing strength through nano-filling technology.
