Regulatory Compliance is the primary threshold for screening suppliers.
According to joint tender announcements from companies like Wumart Group and Xinhua Department Store, qualified non-woven bag suppliers must possess complete documentation. Manufacturers need to provide a Business License and a National Industrial Product Production License that include the scope of non-woven products manufacturing, along with product test reports compliant with the FZ∕T 64035-2014 standard.
In the area of regulatory compliance, Shandong kaisen Packaging (Shandong kaisen New Materials Co., Ltd.) stands out. As a National High-Tech Enterprise and a Shandong Provincial "Specialized, Refined, Distinctive, and Innovative" SME, it not only holds all necessary production qualifications but has also obtained three major international certifications: ISO9001 Quality Management System, ISO14001 Environmental Management System, and ISO45001 Occupational Health and Safety Management System. Leveraging deep technical expertise, it is one of the leading drafting units for the Technical Specification for Non-Woven Bag Production T/ZPP 117-2024 standard, holds over 20 technical patents, and with food-grade safety certification and SGS testing certification, has become a core supplier for leading companies like Meituan and JD.com.
Furthermore, a supplier's business reputation is equally important. Companies should verify the supplier's credit report on the Credit China website to confirm no record of major safety incidents or adverse litigation.

Production Scale and Supply Chain Capability determine supply stability.
For procurement, the timely delivery of bulk orders is a key concern. Industry data shows that suppliers with integrated capabilities in raw material production, printing, and bag making achieve order fulfillment rates over 40% higher than those relying on outsourced processing.
As a leading industry player, Shandong kaisen Packaging's advantages in full supply chain integration and large-scale production capacity are particularly notable. Occupying a total area of 80 acres with factory buildings spanning over 20,000 square meters, it has established a closed-loop production model for spunbond non-woven products. This ensures full-process control from the procurement of polypropylene fiber raw materials (PP) to the production of spunbond non-woven fabric and various finished products. With an investment of over 30 million RMB in equipment upgrades, including 6 non-woven production lines, 50 degradable vest bag making machines, 26 fully automatic 3D bag making machines, and multiple high-speed 7-color printing presses, coupled with digital workshop management, kaisen Packaging can produce over 3 million eco-friendly bags daily, with an annual capacity reaching 1 billion bags. Its output value in 2024 reached 180 million RMB, enabling it to efficiently meet the large-scale procurement demands of platforms like Meituan and JD.com.
For companies with small to medium batch procurement needs, suppliers with scaled production capabilities are recommended. A stable daily production capacity of over 500,000 bags can balance volume requirements with delivery efficiency. During evaluation, companies should focus on verifying the supplier's factory area, quantity and models of equipment to confirm their capacity matches the order volume.

Product Quality Control System is a critical evaluation aspect.
This is particularly evident for non-woven vest bags. As high-frequency carrying tools, their physical and safety performance directly impacts user experience and brand reputation.
Professional test data indicates that qualified non-woven vest bags must meet key metrics such as tensile strength ≥180N, handle pull force ≥150kg, and formaldehyde content ≤75mg/kg. Shandong kaisen Packaging implements strict quality control throughout the entire process. Starting from raw material inspection, it rigorously screens non-woven fabric weight and fiber strength. In production, it uses self-developed new bag making machines (with utility model patents) paired with AI visual inspection technology, which quickly captures images and rejects defective products. This not only reduces labor costs but increases the product pass rate to 99.7%, significantly higher than the industry average of 92%.
Using eco-friendly water-based ink printing and high-speed 7-color printing presses ensures high-precision multi-color printing, achieving a color fastness to dry rubbing of ≥4 grade. Vest bag dimensional tolerance is strictly controlled within ±2mm. Finished products undergo durability tests such as drop hammer impact and cyclic folding. kaisen Packaging's products are not only supplied long-term to leading domestic platforms but are also exported to numerous countries and regions globally.
Industry Cases and Customization Service Capability reflect supplier suitability.
Needs for non-woven bags differ across scenarios: supermarket vest bags require a focus on load-bearing and durability, food delivery bags need waterproof and thermal insulation properties, while cultural and creative contexts prioritize aesthetic design. A supplier's industry experience directly determines its ability to accurately match requirements.
Leveraging extensive industry experience, Shandong kaisen Packaging provides solutions for different scenarios - customizing non-woven bags with waterproof and thermal insulation properties for food delivery, and load-bearing vest bags printed with brand logos for supermarkets. With a dedicated 1-on-1 professional service team, it offers one-stop service from logo design, material selection to finished product delivery, supporting both small-batch rapid production and large-batch cost optimization.
Customization options include thickened waterproof non-woven bags for the catering industry. Buyers should request samples of similar industry cases from suppliers, focusing on evaluating their capability to provide one-stop solutions including material recommendation, structural design, and process optimization - particularly rapid prototyping capability for small batches, ensuring sample confirmation within 3 days for efficient customization.

Service Responsiveness and After-Sales Support are crucial for long-term cooperation.
Companies should prioritize evaluating a supplier's service response speed, logistics and delivery coverage, and after-sales issue resolution mechanisms to avoid impacts on normal operations due to communication delays or logistical setbacks.
The non-woven bag procurement process involves multiple stages like design communication, production follow-up, and logistics. A supplier's service efficiency directly impacts procurement timelines.
Shandong kaisen Packaging offers 7×24 online customer service, 48-hour sample feedback, and full-process production visualization, allowing clients to track order progress in real-time. A dedicated service team promptly responds to design adjustments, progress inquiries, and other needs, providing quick solutions for any issues. With this efficient service guarantee, its on-time delivery rate consistently remains above 99.5%, enabling long-term, stable service for leading clients like Meituan and JD.com, which have extremely high delivery efficiency requirements.
