The selection of packaging materials for skincare products directly affects product stability, user experience, and brand positioning, and needs to be comprehensively considered based on ingredient characteristics, texture, usage scenarios, and environmental protection requirements. The following is a guide for selecting packaging materials for different categories of skincare products, with a comparison of key parameters:
1.Core principles for packaging material selection
- Component compatibility: Avoid chemical reactions between packaging materials and active ingredients (such as acid corrosion of metals).
- Sealing and protection: Block oxygen, ultraviolet rays, and microorganisms, extending shelf life.
- Convenience of use: Consistent with the product’s usage logic (such as using a dropper to extract essence or a pump head to extract lotion).
- Environmental Protection and Cost: Recyclable materials (such as glass, PCR plastics) balance cost and sustainability
2.Packaging material solutions for different skincare product categories
- Makeup toner/toner
A preferred packaging material:
Plastic bottle+inner stopper: Made of PETG material (high transparency, alcohol resistance), paired with a quantitative inner stopper to prevent spillage (such as Dr. Chengye’s water control).
Spray bottle: aluminum cans (ampoules) or glass bottles+metal nozzles (such as Evian spray), and the atomization effect depends on the nozzle aperture (0.3-0.5mm is the best).
B Avoid Pit Tip: Avoid using ordinary PP plastic, as alcohol or acid components may cause contamination from dissolved substances.
- essence liquid
Highly active ingredients (vitamin C, retinol):
Brown/black glass bottle+dropper: anti ultraviolet oxidation (such as Suolico CE essence), and the dropper needs butyl rubber plug to prevent leakage.
Vacuum compression bottle: completely isolated from air (such as The Ordinary essence), suitable for oil-free formulas.
Oil essence (squalane, rose hip oil):
Glass bottle+rubber dropper: Avoid light and corrosion (such as HABA squalane oil) to prevent plastic swelling.
- Lotion/Cream
Wide mouth bottle: made of glass or ceramic (lady face cream such as La Mer), with scoop to avoid hand pollution.
Pressing pump bottle: vacuum/airbag pump design (such as Sisley universal emulsion), one-way discharge to prevent backflow pollution.
Environmental protection plan: Replacement design (core+shell separation, reducing packaging waste, such as Shiseido Yuewei series).
- Sunscreen/Isolation Cream
Flexible hose: Aluminum plastic composite pipe (UV resistant+high sealing), with a small pipe opening (such as Lifuquan Mobile).
Vacuum bottle: prevents sunscreen from becoming ineffective due to oxidation (such as AnaSun Gold bottle).
- facial mask/paste products
Aluminum tube: it can isolate light and air (such as Fulaishi Black Tea facial mask), suitable for containing highly active plant extracts.
PET tank+sealing film: paste cleaning facial mask (such as Keyan white mud), which needs to be attached with a scraper for use.
