Qingdao Wang Paper has officially become the world's first enterprise to mass-produce water-based barrier MONO material packaging products. This milestone arrival marks the official entry of the sustainable packaging industry into the "MONO material era". The technical team of the world-renowned pulp and paper giant APP came to our company's production site for office guidance and witnessed the arrival of this historic moment.
The main breakthroughs include: stable large-scale production: After thousands of machine tests and high-precision equipment optimizations, the consistency of quality monitoring for millions of orders has been guaranteed. Cost optimization: By adopting the in-machine one-piece molding technology, the traditional lamination process is eliminated, significantly reducing production costs.
Certification Breakthrough: Aqueous lined paper cup have also been certified by the FDA as food contact materials and have established market access globally. Data shows that the main indicators of the MONO water-based barrier paper products produced on a large scale this time, such as the forming speed and the qualified rate of finished products, have all significantly improved. The data prove the technical value of the "first batch of aqueous lined paper cup produced".
Barrier performance: Ensure that the penetrant remains in a hot drink state at 95℃ for 20 minutes to 2 hours, preventing leakage.
Stiffness test: Compared with traditional methods, both empty paper cups and those filled with liquid have higher stiffness.
Recyclability: The paper cups made of aqueous lined MONO material comply with international recycling standards. The recovery rate was as high as 98.8% as tested by the Paper Technology Foundation (PTS) of the United States. Aqueous lined paper cup can be recycled and reused during the papermaking process, which strongly supports global sustainable development and resource recycling.
Biodegradability and compostability: Aqueous lined paper cup have obtained DIN & ABA industrial degradability certification and household compostability certification, ensuring their degradability in the natural environment and effectively reducing the environmental burden.
Heat resistance and microwave safety: The aqueous lined paper cup has successfully passed the microwave heat resistance test (EN15284 standard), confirming that it does not release harmful substances during microwave heating and always maintains good packaging performance. Its excellent high-temperature resistance ensures the safety of the product during actual use.
At present, the first batch of aqueous lined paper cup has been pre-ordered by many well-known brands at home and abroad. We are looking forward to receiving a warm response in the market and opening up a new direction for mass production in the industry.
These are three different types of paper cups, made of PE, PLA and aqueous lined paper.
Tests for natural decomposition buried in the natural environment.
Experimental process: Put PE, PLA and aqueous lined paper cup together, dig a pit in front of the research building, and let them degrade naturally. Each time it is unearthed, it should be put back in its original place to observe its condition.
After 245 days,the aqueous lined paper cup had completelydegraded,the fibers of PLA had been degraded,the film of PLA hadruptured,and the film of PE was basically intact.
Experimental conclusion:The degradation degree from high to low was aqueous lined paper cup >PLA>PE.
