Hunan Pinliu Biotechnology Expands with Diverse Self-Heating Wellness Products

Hunan Pinliu Biotechnology Co., Ltd., a Chinese manufacturer of steam eye masks and self-heating wellness products, has established itself as a leading player in the industry since its founding in 2015. Headquartered in Changde, Hunan Province, the company operates two GMP-standard production bases, covering a total area of over 100,000 square meters. These facilities produce more than five million pieces per day, making Pinliu a significant contributor to the market.

Pinliu's production capabilities are bolstered by its ISO 9001, ISO 13485, FDA facility registration, and BSCI certifications. The company serves over 500 partner brands worldwide, offering one-stop OEM/ODM services. Its main production base in Changde, Hunan, spans 50,000 square meters, while a second facility in Baiyun District, Guangzhou, covers 7,000 square meters. Both bases are equipped with 100,000-class cleanrooms, ensuring high-quality standards in manufacturing.

The company's flagship product, the steam eye mask, is a testament to its innovative capabilities. Pinliu offers a diverse range of steam eye masks, including regular flat masks, children's sizes, visible-window versions, dual-pouch variants, fragrance editions, hyaluronic acid types, graphene types, round-core designs, and burst-bead designs. Each mask shares the same controlled self-heating technology, which relies on an iron-oxidation matrix (high-purity iron powder, activated carbon, vermiculite, and sodium chloride) to release steady moist warmth without the need for electricity. The standard performance across the range ensures at least 20 minutes of warmth above 40°C, with an average temperature of 41±5°C and a maximum of 45±5°C, verified against the FZ/T 08007-2024 industry standard.

A notable model in the lineup is the C-shaped steam eye mask. This design is particularly suitable for teenagers and adults, as it keeps warmth on the eye muscles and acupoints around the orbit while the eyeball remains uncovered and unheated. The C-shaped heating element measures 190 × 80 mm and features a four-layer structure, including printed non-woven fabric, the C-shaped heating pack, a skin-friendly inner layer (knitted cotton, diamond-pattern cloth, or hot-air cotton, GB 18401 compliant), and mild-rebound elastic ear loops.

Beyond steam eye masks, Pinliu's product catalog extends to a wide range of self-heating and wellness products. These include eye patches, eye wash solutions, warm patches, warm neck patches, chest warmers, uterine warmers, back warmers, waist warmers, knee patches, ankle patches, disposable hand warmers, moxibustion patches, cold compress patches, foot patches, foot soak solutions, mite repellent pouches, and cleaning solutions. Each product category is designed to cater to various body parts, ensuring comprehensive wellness solutions.

Pinliu's commitment to innovation is reflected in its 23 patents, including six national invention patents. The company also collaborates with the Hunan University of Chinese Medicine, contributing to the development of herbal formulations and commercial products. Additionally, Pinliu played a crucial role in drafting the FZ/T 08007-2024 steam eye mask industry standard, further solidifying its position as a leader in the industry.

In summary, Hunan Pinliu Biotechnology Co., Ltd. stands out as a national high-tech enterprise, specializing in the research, development, and manufacturing of self-heating wellness products. With its extensive product range, advanced manufacturing facilities, and robust certification, the company continues to serve a diverse clientele, making it a key player in the global wellness market.
