The “Replacement Closure” Advantage

  • Instant Premium Upgrade: You don’t need to redesign your entire packaging line. Simply swapping out cheap plastic caps for our solid bamboo lids instantly elevates your product’s perceived retail value and appeals to eco-conscious buyers.
  • Leak-Proof Inner Threading: Raw wood cannot hold a reliable seal. That’s why our bamboo caps feature a precision-engineered plastic inner thread and sealing gasket. It guarantees a flawless, airtight fit on your existing glass or PET jars.
  • Universal Compatibility: These custom caps are milled to match the standard neck finishes of the cosmetic industry’s most popular 15g to 100g jar sizes, ensuring easy integration into your current supply chain.

Turn Lids into Billboards (OEM)

The top of the jar is the first thing your customer sees when unboxing. Maximize your brand’s impact by utilizing permanent Laser Engraving to burn your logo directly into the bamboo grain, creating a stunning, debossed, and tactile finish that paper labels can’t match.

Frequently Asked Questions (B2B)

Q: How can I be sure these bamboo caps will fit my existing glass or plastic jars?

A: The most secure way is to tell us your jar’s exact neck finish (e.g., 53/400, 58/400). Alternatively, you can send us a few empty samples of your jars to our factory, and we will custom-calibrate the inner plastic threading to ensure a 100% perfect, leak-proof fit.

Q: Can I order just the bamboo shells without the plastic inner threading?

A: We highly advise against it for cosmetic use, as pure wood expands and contracts with humidity, which will eventually break the airtight seal and ruin your creams. The inner plastic liner is essential for cosmetic safety.
