Disposable Double Wall Paper Cups with Custom Printing and Eco-Friendly PHA

Product Specification

Addressing the global challenge of plastic pollution, Nanwang introduces the groundbreaking PHA-coated paper cup. PHA (Polyhydroxyalkanoates) is a natural polyester produced by microorganisms, hailed as the "next-generation biomaterial." Unlike traditional PE plastic or PLA coatings, PHA-coated paper cups can biodegrade not only in industrial composting facilities but also completely in natural environments like oceans and soil, breaking down into water and CO₂ by microorganisms. This offers a fundamental solution to "white pollution" at its source, making it the ideal choice for brands pursuing ultimate sustainability.

• True Marine & Soil Biodegradability: PHA fully biodegrades in various natural environments without creating microplastics, providing a fundamental solution to plastic leakage.

• Excellent Food Safety: PHA itself offers superb biocompatibility; the coating is safe and non-toxic, perfectly suitable for both hot and cold beverages.

• Strong Heat Seal & Leak Resistance: The coating provides excellent sealing, ensuring a sturdy, leak-proof cup for a worry-free user experience.

• Broad End-of-Life Compatibility: Suitable for industrial composting and biodegradable in home composting conditions (depending on specific PHA type/thickness), adapting to future waste management trends.

• Carbon-Negative Environmental Contribution: PHA production often uses renewable resources, helping reduce carbon emissions and supporting brands' carbon neutrality goals.

• Enhanced Brand Value: Using PHA-coated cups is a powerful statement of your brand's commitment to environmental protection, significantly boosting brand image.

• Technological Foresight & R&D Strength: As a drafting unit for the National Standard GB/T 27590-2022 "Paper Cups", Nanwang Tech stays at the forefront of packaging technology. We invest heavily in R&D for novel materials like PHA, ensuring future-proof solutions for our clients.
• Robust Quality & Food Safety System: Our BRC (Grade A+) certification and in-house laboratory ensure strict testing of every batch of PHA material and finished products, guaranteeing product performance and absolute food safety.
• End-to-End Solution from Lab to Market: We provide not just products, but also technical knowledge support and marketing guidance on PHA technology, helping you effectively communicate this eco-choice to your consumers.

Q1: What's the difference between PHA coating and PLA coating?

A: The key difference is the degradation environment. PLA typically requires specific industrial composting conditions (around 58°C). PHA, however, biodegrades in ambient conditions—soil, seawater, even home compost bins—offering a broader, more environmentally friendly solution.

Q2: How does the PHA coating perform regarding water resistance and heat tolerance?

A: Performance is excellent. The PHA coating provides water and grease resistance comparable to traditional PE coatings, safely holding hot beverages above 90°C without leakage or softening during use.

Q3: Are PHA-coated paper cups more expensive?

A: Currently, due to the early stage of PHA raw material production and processes, costs are higher than traditional PE and PLA. However, costs are decreasing with scaling technology and demand. For brands prioritizing premium image and genuine environmental impact, the value PHA adds often outweighs the cost difference.
