As a leading listed domestic enterprise specializing in pet hygiene products, Tianjin Yiyi Hygiene Products Co., Ltd. has years of deep cultivation in the disposable care industry and owns over 80 independent patents. Its representative patented products include the bamboo pulp pet pad under Patent No. 201921173512.2, the PCR material pad under Patent No. 202420333800.4, and the pH color-changing health monitoring pad under Patent No. 201520950728.0. Centered on three core strengths-natural low-carbon production, plastic circular utilization and pet health monitoring-these technologies redefine industry standards for pet care pads, demonstrating Tianjin Yiyi's innovation capacity and commitment to sustainable development.
Patent No. 201921173512.2: Eco-Friendly Bamboo Pulp Pet Pad
The core innovation of this patent lies in the adoption of natural unbleached virgin bamboo pulp as raw material, breaking the industry's long-standing reliance on wood pulp and realizing green upgrading at the raw material stage. Most manufacturers in the sector use bleached wood pulp for pet pads, a process that generates massive volumes of chemical wastewater and causes ecological damage through deforestation. This patented design innovatively uses natural bamboo pulp: bamboo features a short growth cycle and rapid regeneration, drastically cutting consumption of forest resources. Naturally containing bamboo chitin antibacterial substances, bamboo pulp effectively inhibits bacterial growth from urine and reduces indoor odors. The pad also delivers outstanding absorption performance. Constructed with six layers of premium raw materials, it absorbs liquid rapidly with extremely low backflow rate, keeping dog's paws dry and comfortable.
Patent No. 202420333800.4: PCR Material Pet Pad
The standout innovation of this pet pad is its waterproof backing film made from post-consumer recycled (PCR) PE plastic. Waste plastic is recycled and reprocessed into the waterproof bottom layer of the pad, forming a closed-loop system for plastic waste recycling and meeting global demands for low-carbon development and circular economy. PCR refers to post-consumer recycled plastic. Waste PE plastic undergoes sorting, cleaning, melting and granulation to partially replace virgin petroleum-based PE for waterproof backing film production. This patent optimizes the modification formula of recycled PE and adjusts the mixing ratio of recycled pellets and virgin resin, enabling the PCR backing film to retain equivalent waterproof, anti-leakage and tensile resistance properties, and guaranteeing the leak-proof and stretch-resistant performance of the pet pad.
Patent No. 201520950728.0: pH Color-Changing Health Monitoring Pet Pad
This patent's highlight is the paw-print acid-base color-changing design on the pad surface, which visually reflects urine pH values to help pet owners quickly screen urinary health issues at home. Acid-base indicators are embedded within the paw-print patterns on the pad. When pets urinate and the liquid soaks the printed area, distinct colors appear according to different urine pH levels: green for healthy pH ranges, orange for acidic urine, and blue for alkaline urine, allowing instant judgment of urinary acid-base balance. It offers pet owners a convenient, efficient method for long-term at-home pet health monitoring.
Conclusion
The three patents embody Tianjin Yiyi's R&D orientation of "ecological sustainability + pet health". Moving forward, Tianjin Yiyi will further invest in intellectual property research and development, iterate hygiene care products with original patented technologies, and balance environmental protection, resource recycling and pet wellness to deliver safer, low-carbon hygiene care solutions for pets worldwide.
