Not sure which plastic to choose for your lotion bottles1? Picking the wrong one can affect product safety, appearance, and your brand’s eco reputation2.
The main difference lies in clarity3, chemical resistance4, recyclability5, and feel: PET6 is clear and premium, HDPE7 is sturdy and chemical-resistant, and PP8 is heat-resistant and versatile.
At ECO-BAMBOO, I see the plastic choice impact everything from shelf appeal9 to real sustainability10. Many beauty brands use PET6 for its crystal clear look, HDPE7 for tough lotions, and PP8 for specialty creams. The blend you choose can help match your product’s needs while keeping your green goals in reach.
What is the main difference between PP8, PET6, and HDPE7 plastic cosmetic packaging?
PET6 stands out for its clarity3 and gloss. HDPE7 is opaque, durable, and chemical-resistant. PP8 is best for parts exposed to heat or high-pH but is less recyclable than PET6 or HDPE7.
Beauty brands want packaging that protects product quality11 and supports their sustainability10 claims. At ECO-BAMBOO, I recommend PET6 for clean, premium products, HDPE7 when strength is the main concern, and PP8 for pump parts or high-alkaline creams.
Cosmetic Packaging Plastics Table
| Property | PET6 | HDPE7 | PP8 |
|---|---|---|---|
| Look & Feel | Clear, glossy | Opaque, matte | Translucent, variable |
| Chemical Resistance | Moderate | High | High |
| Heat Resistance | Moderate | Good | Excellent |
| Common Use | Bottles, jars | Bottles, tubes | Caps, pumps, creams |
| Recyclability | High | High | Medium |
What is HDPE7 and why is it used for cosmetic bottles?
HDPE7 stands for High-Density Polyethylene. It’s used for cosmetic bottles because it’s tough, highly chemical-resistant, leak-proof, and widely accepted in recycling streams.
With clients concerned about leaks or aggressive formulas, I recommend HDPE7 every time. It’s strong enough for daily use and protects products from air and light. HDPE7’s resilience ensures your lotion arrives intact, while its recycling readiness fits most eco strategies.
Which plastic is best for lotion?
PET6 is best for premium, clear packaging and good recyclability5. HDPE7 is ideal for opaque, sturdy bottles and tough formulas. PP8 is useful for closures or products that get hot or have high pH.

Matching plastic type to lotion properties is key. For luxury serums, I use PET6 to highlight colors and purity. For hand creams or sunblock, HDPE7 gives strength and chemical protection. PP8 wins for pumps and lids, and for those heat-sensitive applications.
Best-Use Matrix
| Product Type | Best Plastic | Reason |
|---|---|---|
| Clear/luxury lotion | PET6 | Clarity, shelf appeal9 |
| Heavy-duty/active lotion | HDPE7 | Strength, leak resistance |
| Pump or closure component | PP8 | Heat/alkaline resistance |
PET6 vs HDPE7 vs PP8 Bottles: Which Material Is Best for Your Product Line?
The best material for your product line depends on shelf presence, formula, recyclability5, and user experience. Combine PET6 or HDPE7 bodies with bamboo collars for eco-appeal and function.
I help global beauty brands balance consumer demands for sustainability10 with regulatory standards. PET6 shines for transparency and mainstream recycling. HDPE7 delivers durability and peace of mind for all-day use. Pairing these with bamboo upgrades the look and story. PP8 adds versatility, especially for components that need extra toughness or flexibility.
Decision Chart
| Factor | PET6 | HDPE7 | PP8 |
|---|---|---|---|
| Look | High-end | Sturdy | Functional |
| Eco Image | Strong | Strong | Fair |
| Best For | Serums | Lotions | Pumps/Caps |
| Bamboo Combo | Excellent | Excellent | Good |
Conclusion
Choosing between PET6, HDPE7, and PP8 shapes your product’s look, protection, and sustainability10. PET6 shines for clarity3, HDPE7 wins for strength, and PP8 supports specialty parts—blending purpose and planet-first thinking.
