Description
The Wet-Pressed Molded Fiber Cup & Lid Set is a fully compostable, plastic-free beverage packaging solution designed to replace conventional paper cups with plastic lids. Made entirely from natural plant fibers — sugarcane bagasse , bamboo pulp and wood pulp — both the cup body and the lid are manufactured through the wet-press hot-forming process, delivering a seamless eco-friendly experience from first sip to final disposal.
While many so-called "eco-friendly" paper cups on the market still use plastic lids (PP or PE), our set solves the problem completely: the lid is also made of molded fiber, ensuring 100% biodegradability. This means the entire cup — body and lid together — can be disposed of in a compost stream, returning to nature in 90 days without leaving any microplastics behind.
The lid is precision-molded using wet-press technology with anti-permeation surface treatment, achieving a fit tolerance of 0.1mm with the cup rim. Tested through 500 open-close cycles without leakage, it performs reliably with hot coffee (up to 100°C), iced beverages, and soups. For coffee chains, tea shops, food service operators, and brands committed to true sustainability, this is the complete package.

Product Details
1 Full Compostability: The Lid Finally Matches the Cup
The dirty secret of the "eco cup" industry:
• Most paper cups branded as "eco-friendly" use PLA-lined paper for the cup body(
• But the lid is almost always made of PP (polypropylene) plastic
• Result: the cup degrades, but the lid persists in landfills for centuries
Our solution is radical in its simplicity: make the lid out of the same plant fiber as the cup. Both the cup body and the lid are crafted from sugarcane bagasse and bamboo pulp through the wet-press process. After use, the entire set can be disposed of together in a composting facility, where it fully biodegrades in 90 days. No separation needed. No plastic residue. No greenwashing.
2 Leak-Proof Lid Technology
The single biggest question customers ask about fiber lids is: "Will it leak?" Here is our answer:
• Wet-press precision molding achieves 0.1mm fit tolerance between lid inner rim and cup rim
• Anti-permeation surface treatment prevents liquid from soaking through the lid material
• Reinforced rim design maintains structural integrity during handling and transport
• Tested through 500 open-close cycles without any leakage
• Compatible with standard cup rim diameters (custom sizes available for OEM orders)
Whether it is 85°C hot latte, iced lemon tea, or hearty soup, the lid stays secure and leak-free throughout the customer journey from counter to table to takeaway.
3 Unified Brand Canvas
A plastic lid is a missed branding opportunity. Our molded fiber lid provides a premium surface for brand expression:
• Lid top can be embossed with brand logo during the molding process — no secondary printing needed
• Cup body accepts full-wrap printing or embossing for 360° brand visibility
• The visual consistency of fiber cup + fiber lid creates a cohesive, premium brand impression
• Natural off-white color communicates "natural" and "eco-friendly" without a single word
