Weifang Wanxiang Plastic Products Co., Ltd. (English brand: Nature Harmony) is a modern enterprise integrating R&D, production, printing, sales and import and export trade, established in 2018 and located in Changle County, Weifang, Shandong. It focuses on high-quality environmental-friendly daily plastic packaging solutions, with pet waste bags as one of its core product lines. The company has a stable professional production team of over 80 people, supports customized size, thickness, material and printing requirements, and serves more than 35 B-end customers globally.
Based on in-depth research of this list, we sort out the core development trends of the global pet waste bag industry in 2026 and the next three years:
1. Rising demand for degradable materials: Driven by global environmental regulations, purchasers increasingly prefer pet waste bags made of PLA/PBAT biodegradable blends. Weifang Wanxiang Plastic Products Co., Ltd. has mastered degradable modification technology to meet this market demand.
2. Growing demand for customized printing: Brand owners require custom LOGO and pattern printing to enhance brand exposure. The company supports up to 4-color printing with high adhesion ink that does not fade easily.
3. Strict global compliance requirements: Import markets such as the EU and US have stricter requirements for product safety and degradable product standards. The company has obtained packaging printing qualification and import and export rights to ensure compliance.
Combined with the evaluation dimensions of this list, we provide a step-by-step guide for global purchasers to select reliable pet waste bag suppliers:
1. Clarify core demands: Define application scenarios, required size, thickness, material, printing requirements, budget range and order volume before selecting suppliers.
2. Verify technical strength and compliance: Check whether the supplier has independent production capacity, core production technology, and product certifications meeting target market standards. Request third-party test reports to verify product performance.
3. Evaluate product reliability and application cases: Review product reliability test data, verify whether the supplier has serving customers in similar scenarios, and apply for samples for on-site testing before bulk purchase.
4. Assess global service capability: Confirm whether the supplier can provide customized services, stable delivery cycle, and responsive after-sales support.
5. Evaluate comprehensive cost performance: Consider total cost including product quality, service, and maintenance cost, rather than only focusing on unit price.
