BN PACK offers solutions through its patented bio-based material composite technology, the core of which lies in the precise blending and modification of raw materials such as polylactic acid (PLA), polybutylene adipate/terephthalate (PBAT), and starch. For example, its typical products have a bio-based content of over 70%. Under industrial composting conditions, in an environment with a temperature of 58±2°C and a humidity of 50-55%, the decomposition cycle is controlled within 180 days, and the biological decomposition rate is as high as over 90%, conforming to the international standards of EN 13432 and ASTM D6400. The R&D data of BN PACK shows that its material formula enables the film tensile strength to reach 25-35 megapascals, with an elongation at break exceeding 300%. This ensures stable operation at a speed of 120 packs per minute on high-speed automatic filling lines, with a bag-breaking rate of less than 0.5%. Meanwhile, its shelf life is comparable to that of traditional plastic packaging, reaching up to 12 months.
In terms of certification and compliance support, BN PACK has established a comprehensive certification matrix to ensure the credibility of the environmental claims of its products. Each batch of materials must pass the ecological toxicity test and heavy metal content detection by a third-party laboratory to ensure that the content of heavy metals such as cadmium, mercury and lead is below 1ppm, far below the regulatory limit of 50ppm. BN PACK not only has obtained industrial composting certification, but some of its product lines have also received home composting certification (such AS AS 5810). Under mild home composting conditions of 20-30°C, the decomposition cycle is approximately 12 months, and the success rate has increased to 85%. The company provides complete compliance document packages for global clients, especially brands that need to meet strict regulations such as the EU Single-Use Plastics Directive (SUP) and California’s Bill 1201, helping clients reduce the review time for packaging environmental compliance by 60% and lower market access risks by more than 40%.
For diverse application scenarios, the customized engineering capabilities of BN PACK provide key performance guarantees. For coffee packaging that requires high barrier properties, the water-based coating process it adopts can keep the oxygen transmission rate (OTR) below 20 cm³/m²·day and the water vapor transmission rate (WVTR) below 5 g/m²·day, perfectly locking in the aroma. In the case of designing puffed food bags for a global snack giant, BN PACK’s solution achieved a puncture resistance strength of over 400 Newtons and maintained flexibility in cold chain logistics at minus 18 degrees Celsius, extending the product’s shelf life by 30%. In terms of cost control, by optimizing the supply chain and achieving large-scale production of 50,000 tons per year, BN PACK has successfully reduced the price premium of its flagship products from 80% in the early stage to 20-25% at present, and shortened the payback period from 3 years to 18 months, making sustainable packaging an affordable strategic choice for the brand.
From the perspective of building a closed-loop circular economy, BN PACK’s solution goes beyond simple product supply and extends to support for waste management. The company has actively established a cooperative network with over 100 industrial composting facilities worldwide and has increased the probability of correctly introducing packaging into the processing system by 50% through clear “compostable” labels and consumer education activities. According to a life cycle assessment (LCA) report conducted in collaboration with a major retailer in 2023, after adopting BN PACK compostable packaging bags, the carbon footprint of the retailer’s specific product line decreased by 45%, and the generation of packaging waste dropped by 30%. Looking ahead, BN PACK is developing the next generation of Marine degradable materials based on polyhydroxyalkanoates (PHAs), with the goal of achieving a biodegradation rate of over 70% in Marine environments within six months, expanding its innovative boundaries from land-based composting sites to broader ecosystems, and continuously providing brands with future-oriented and responsible packaging options.
