In recent years, global attention to plastic pollution has continued to rise, and governments and consumers worldwide are increasingly demanding environmentally friendly packaging. The food packaging industry, as a major consumer of plastics, is facing unprecedented pressure for transformation. Traditional PE coated paper, due to its excellent oil and water resistance, has dominated the food packaging field, but its non-degradable nature makes it urgently necessary to find sustainable alternatives in the context of increasingly strict environmental regulations.
Against this backdrop,PLA coated paper, as an innovative environmentally friendly material, is rapidly becoming an industry focus. Leading enterprises in the industry, such as Zhejiang Yizhouyuan New Material Technology Co., Ltd., have successfully developed and mass-produced high-performance PLA coated paper with their profound technical accumulation.
• Excellent Oil and Water Resistance: Inherits the advantages of PE coated paper, effectively blocking oil and water, ensuring the freshness and hygiene of food, and is suitable for various hot and cold drinks, fast food boxes, etc.
• Biodegradability: As a bio-based biodegradable material, PLA degrade under specific conditions (such as industrial composting environments), significantly reducing the burden on the environment and conforming to the concept of a circular economy.
• Food Contact Safety: Adopts food-grade raw materials and production processes to ensure that products comply with international food contact material standards, are non-toxic and harmless, and protect consumer health.
• Wide Applicability: Can customize coated paper with different grammage, thickness, and peel strength according to customer needs, suitable for high-speed automated production lines, meeting diverse packaging needs.
Yizhouyuan and other enterprises not only provide high-quality PE/PLA coated paper products but also help downstream food packaging enterprises achieve green transformation by providing full-process customization services. From raw material selection, product design, manufacturing to quality control, professional teams participate throughout the process to ensure that customers get the most suitable environmentally friendly packaging solutions for their products and market needs. This one-stop service model greatly reduces the threshold and risk for enterprises to transform and upgrade.
With the continuous improvement of global environmental regulations and the continuous enhancement of consumer environmental awareness, the market demand for environmentally friendly materials such as PE/PLA coated paper will continue to grow. In the future, sustainable development will no longer be a "bonus item" but a "must-have option" for the food packaging industry. Zhejiang Yizhouyuan New Material Technology Co., Ltd. will continue to cultivate in the field of environmentally friendly materials, and through technological innovation and high-quality services, work with global partners to promote the food packaging industry towards a greener and more sustainable future.
Although PLA (polylactic acid) coated paper offers significant environmental advantages, its adoption was once constrained by technical bottlenecks. Early PLA coated paper suffered from insufficient heat resistance, poor compatibility with high-speed cup forming machines, and relatively high costs, leading some companies to revert to traditional PE coating solutions. However, with continuous advancements in materials science and processing technologies, these barriers are being systematically overcome.
Through years of R&D investment, Zhejiang Yizhouyuan New Material Technology Co., Ltd. has successfully resolved critical challenges such as adhesion control between the PLA coating and the paper substrate, coating uniformity, and heat-sealing performance optimization. The company’s PLA coated paper maintains stable physical properties within a temperature range of -10°C to 90°C, making it suitable for both cold beverage packaging and short-term hot beverage applications such as coffee and tea. Furthermore, by adjusting the coating formulation and thickness, the product achieves good compatibility with mainstream high-speed paper cup forming machines, with production speed and quality stability approaching those of traditional PE coated paper.
Cost has historically been the biggest obstacle to the widespread adoption of PLA coated paper. As PLA resin production capacity expands, manufacturing processes mature, and economies of scale take effect, the price gap between PLA coated paper and PE coated paper is gradually narrowing. Industry data shows that the comprehensive cost of PLA coated paper has decreased by approximately 30% over the past five years. Leveraging its annual production capacity of over 50,000 tons, Yizhouyuan further reduces unit product costs through centralized procurement and process optimization, enabling more small and medium-sized food packaging companies to adopt environmentally friendly materials.
In addition, the company has introduced PLA/PBAT blend coating solutions. While maintaining biodegradability, these blends improve the flexibility and impact resistance of the coating layer, expanding the application of PLA coated paper into areas such as frozen food packaging and oily food packaging.
It should be noted that the environmental value of PLA coated paper is highly dependent on post-consumer collection and treatment systems. PLA degrades slowly in natural environments and requires industrial composting conditions (approximately 60°C, high humidity, and sufficient oxygen) over several weeks to months to fully break down into carbon dioxide and water. Globally, the coverage of industrial composting facilities remains uneven, with some regions lacking the necessary infrastructure.
In response, Yizhouyuan clearly labels the proper disposal methods for PLA coated paper on its product packaging and actively collaborates with downstream customers and municipal waste treatment organizations to promote the development of separate collection and targeted composting channels. At the same time, the company is monitoring the development of next-generation biodegradable materials such as PHA and cellulose-based coatings, preparing for future technological transitions.
Plastic restriction and ban policies worldwide are the core drivers of growth in the PLA coated paper market. The EU’s Single-Use Plastics Directive, China’s plastic ban, and plastic restriction regulations in several U.S. states all explicitly require reductions in single-use plastic products and encourage the adoption of bio-based, degradable alternative materials. Driven by these policies, major fast-food and beverage chains such as Starbucks, McDonald’s, and Heytea have begun procuring PLA coated paper cups in bulk, catalyzing green transformation across the entire supply chain.
As an upstream material supplier, Yizhouyuan has obtained multiple international certifications, including FSC, WCA, and BRC, and exports its products to markets across Europe, North America, Southeast Asia, and beyond. The company closely tracks policy developments and continuously develops product versions that comply with regional regulatory requirements, offering customers an integrated solution combining compliance, environmental protection, and performance.
The food packaging industry is at a critical juncture, transitioning from traditional plastics to environmentally friendly materials. PLA coated paper, with its excellent biodegradability and good performance characteristics, has emerged as one of the most competitive alternative solutions available today. Zhejiang Yizhouyuan will continue to increase R&D investment, optimize production processes, reduce the cost of eco-friendly materials, and actively promote the development of post-consumer collection and treatment infrastructure. Only when material innovation and downstream processing capabilities advance in tandem can the food packaging industry truly achieve its sustainable development goals.
