Better materials, better closures. We form cellulose‑rich bamboo pulp via wet‑press molding to achieve crisp geometry, smooth surfaces, and consistent tolerances—the foundation for a cap that feels premium in hand and fits reliably on the line. The dense fiber structure provides durable strength while keeping weight low, and the single‑material build simplifies end‑of‑life guidance for your customers.

Your application drives the design. Share neck‑finish specs (e.g., diameter/height/threads) or cup rim dimensions and we’ll engineer a precise rotary or press‑fit profile. Add grip ribs for easy twisting, knurling for torque, or a shallow domed top for a sleeker silhouette. For presentation sets or gift packs, we can create decorative over‑caps that slide over your primary closure. Branding stays elevated and eco‑authentic with embossed/debossed logos and custom color matching—no inks or laminates required.

Because real‑world conditions vary, we offer options. Request a moisture‑resistant finish for humid or chilled routes, or keep the cap uncoated for the simplest recycling/compostability. If you need liquid‑tight performance, plan for an inner seal, liner, or compatible primary closure; molded pulp caps are ideal as outer/secondary covers or dust caps. Operationally, caps ship nested to lower pallet heights and storage footprint, and their repeatable fits help maintain line speed. With OEM/ODM support and an MOQ of 5,000 pieces, you can prototype quickly, validate on your filling/packing line, and scale a biodegradable bottle cap that protects, presents, and aligns with your sustainability goals.

FAQs :
Q1: Are these caps leak‑proof?
A: Molded pulp caps are best as outer/secondary closures or dust caps. For liquid‑tight sealing, pair with an inner liner or primary closure.

Q2: Can you match my neck finish or cup size?
A: Yes. Provide dimensions or CAD (neck diameter, thread profile, or cup rim) and we’ll engineer a precise rotary or press‑fit design.

Q3: What branding options do you offer?
A: Embossed/debossed logos and custom color matching are available for a premium, ink‑free look.

Q4: Are they food‑safe and biodegradable?
A: They’re fiber‑based and designed to be biodegradable. For direct food‑contact compliance and documentation, please share your market requirements.

Q5: What is the MOQ and can I order samples?
A: MOQ is 5,000 pcs. Samples can be arranged; typical lead time depends on tooling and order size. Request a fast quote for timelines and pricing.
