A: Our company has been deeply engaged in the specialized R&D of all-PP eco-friendly tarpaulins for over a decade. We have established long-term, regular industry-academia-research collaboration mechanisms with domestic universities and specialized materials research institutes, focusing on continuous iteration and breakthroughs in three core technologies: optimization of PP modification formulations, integrated extrusion and thermal lamination processes, and long-lasting outdoor weather-resistant protection systems. The company is equipped with dedicated, specialized testing equipment and has long conducted small-scale sample production, formulation iteration and debugging, and outdoor natural aging tracking tests for over five years, accumulating a vast database of real-world operating conditions and mature technical parameters. Product development strictly adheres to a three-tier validation system comprising small-scale trials, pilot-scale trials, and large-scale mass production. The company’s complete set of production processes—including PP woven fabric manufacturing, PP extrusion thermal lamination, and modification—is highly mature and stable, effectively addressing common industry quality issues such as delamination, uneven fabric surface, and unstable weather resistance. Leveraging long-term technical expertise, the company has established a tiered, all-scenario product system capable of precisely meeting diverse application needs, including short-term temporary covering, medium- to long-term outdoor use, permanent membrane structure projects, and specialized anti-corrosion applications. In addition to standardized products, the company possesses the capability for targeted R&D of new materials and formulations, enabling it to provide customized R&D and production support services tailored to the specific project requirements of major clients.

A: Our company’s PP eco-friendly tarpaulin project has a cumulative total investment of approximately 60 million yuan, of which 50 million yuan was allocated to specialized, complete sets of production equipment. With the core strategic goal of building a smart, end-to-end production base, the company is gradually implementing intelligent operations across the entire process—including automated extrusion lamination, real-time in-line quality inspection, automated slitting and packaging, and smart warehousing and shipping—to minimize quality deviations caused by manual operations and comprehensively improve product batch consistency and order delivery efficiency. Currently, the first phase of standardized production lines has achieved stable mass production. The effective width of finished products ranges from 1 m to 3.2 m, with standard lengths including 50 m, 100 m, and 150 m. We also offer precise cut-to-length services and customized production solutions to meet specific project requirements.

A: The company’s brand-new standardized production facility will officially begin operations next year, with plans to add two specialized smart production lines equipped with 5-meter ultra-wide-width production machinery as their core components. Once the 5-meter ultra-wide production lines are operational, they will effectively meet the needs of large-scale projects such as membrane structure engineering, large-area landfill liner applications, and marine aquaculture net enclosures. This will significantly reduce product seams, lower on-site hot-air welding costs, shorten project construction cycles, and fully meet the high-standard supply requirements of large-scale engineering projects. With expanded production capacity and upgraded production lines, the company will establish a routine safety stock system to completely resolve the issue of delayed delivery during peak industry seasons, ensuring efficient and on-time delivery of orders for strategic partner distributors and long-term major clients.

A: Our company treats source control of raw materials as the first and most critical step in quality control. We have established a rigorous upstream supply chain admission and screening mechanism, sourcing all core raw materials from leading domestic petrochemical companies and internationally renowned brands such as ExxonMobil. All raw materials entering the factory undergo a sampling and quality inspection process, during which core indicators—such as melt flow index, antioxidant protection systems, and basic mechanical properties—are rigorously verified. We maintain traceability records for every batch of raw materials, ensuring they are verifiable, traceable, and controllable. The base fabric for our tarpaulins is woven exclusively from high-quality virgin PP yarn, and the large-scale mixing of recycled materials is strictly prohibited. Before each batch of PP yarn enters production, mandatory testing for tensile strength, elongation, and basic weather resistance is conducted; any non-compliant raw materials are strictly prohibited from being used in production. Most low-cost PP woven and laminated tarps on the market are produced using a mixture of recycled waste materials, resulting in significant performance variations between batches, brittleness and powdering during outdoor use, and rapid degradation of UV resistance. Our company ensures raw material purity and performance stability from the source, fundamentally eliminating post-sale risks such as product cracking, aging, and cargo contamination. At the same time, we can tailor modified raw material solutions of varying grades based on customer budgets and application scenarios to achieve the optimal balance between performance and cost.

A: Our company has established its own standardized, independent materials testing laboratory, equipped with a full suite of high-precision professional testing equipment, including a UV weathering tester, horizontal and vertical flame retardancy testers, a universal tensile testing machine, a tear strength tester, a peel strength tester, and a flex fatigue tester. We have assembled a dedicated quality control team composed of technical personnel with master’s degrees, who are fully responsible for specialized tasks such as formulation sample optimization, random sampling of mass-production batches, tracking of outdoor aging samples, and the preparation of test reports. Standard samples are retained for all mass-produced products, and comprehensive production batch records are maintained to ensure traceability throughout the product’s entire lifecycle. Products are routinely submitted for testing to authoritative domestic testing institutions and EU-standard certification bodies. We hold a full suite of domestic and international compliance certificates, including ISO Quality Management System certification, SGS test reports, RoHS, and REACH, which fully meet the qualification review requirements for domestic municipal engineering and state-owned enterprise bidding projects, while also complying with market access reviews and customs inspection standards in overseas markets such as Europe, the United States, Southeast Asia, and the Middle East. The company can support on-site random sampling and testing for customers, as well as coordinate with authoritative third-party institutions to conduct independent testing. We can customize testing plans based on national standards, EU standards, or technical specifications designated by the customer.

A: Our products are all-PP homogeneous, one-piece tarps, with both the base fabric yarn and the surface coating made of pure PP, ensuring that the base material and the coating share the same composition and origin. In contrast, the mainstream PVC and TPU tarps on the market all use a composite structure consisting of a “polyester base fabric + heterogeneous functional coating,” where the material properties of the base fabric and the coating are completely different. This structural difference serves as the underlying technological foundation for the various core advantages of our products.

A: The product is environmentally friendly and non-toxic; it contains no harmful substances such as plasticizers or heavy metals and can be directly recycled, pelletized, and reused. Since the base fabric and the coating are made of the same homogeneous PP material, there is no need to peel off layers or separate materials after shredding for recycling. The recycling process is simple, and the recycling rate is extremely high. In contrast, PVC and TPU tarps consist of a polyester base fabric combined with dissimilar coating materials, making them difficult to separate during recycling and resulting in high processing costs; the vast majority can only be disposed of as solid waste. With global environmental policies continuing to tighten, many countries in Europe and the United States have gradually restricted the import and engineering applications of PVC-based products. Major domestic infrastructure projects, foreign-invested enterprises, and foreign trade orders all prioritize the use of recyclable, eco-friendly materials. Our all-PP eco-friendly tarpaulins fully comply with various high-end environmental access standards.

A: PP has a specific gravity of 0.9, which is significantly lower than PVC’s 1.35. For the same grammage per square meter, our PP tarps feature a thicker film layer and offer superior surface flatness, stiffness, and elasticity.

When customers order based on thickness, products of the same thickness weigh less, which can effectively reduce logistics and transportation costs. During on-site installation, the product is easier to handle, lay out, and dismantle, significantly reducing labor requirements for large-scale projects and effectively improving the project’s overall economic efficiency.

A: Our PP tarpaulins possess natural self-cleaning properties based on the physical characteristics of the base material itself, eliminating the need for additional functional coatings. The self-cleaning effect of traditional PVC tarpaulins relies on post-production surface coating treatments; however, after prolonged exposure to outdoor elements such as wind, sun, and friction from sand and gravel, the coating is highly susceptible to wear and peeling, causing the self-cleaning performance to deteriorate rapidly. Since our products have no external functional coatings, there is no risk of coating failure. Provided the base material is not severely damaged, rainwater can naturally wash away surface stains, keeping the fabric clean over the long term and significantly reducing long-term maintenance and cleaning costs.
