Why photoprotection is critical for preserving bio-active chemical compounds and food products.
Standard glass lets harmful UV radiation (290nm–400nm) pass through easily, initiating photochemical degradation. Our specialized UV-blocking glass absorbs up to 99% of wavelengths in this region by incorporating trace metal oxides, including iron oxide, manganese oxide, and selenium during batch melting.
Light exposure triggers decomposition of sensitive compounds such as vitamins, essential oils, cannabinoids, and delicate flavor profiles. Our containers maintain molecular integrity, helping prevent color changes, loss of fragrance, and degradation of key active ingredients over time.
By using physical barrier properties instead of chemical additives, our photoprotective glass bottles reduce the need for synthetic chemical stabilizers or preservatives within your formulation, keeping your labels clean, green, and consumer-approved.

A closer look at our high-volume production facilities, ensuring precision and structural consistency.
We deploy high-speed I.S. (Individual Section) forming machines capable of handling complex geometries for both narrow neck press-and-blow (NNPB) and blow-and-blow forming processes. This technology allows us to maintain consistent wall thickness, optimizing the light transmission barrier across the entire glass body.
Fully automated bottling production line controlled by microcomputer, multiple quality inspections, strict control of product quality.
Implemented alongside manual multiple quality inspections to ensure we satisfy the highest standards and deliver top-grade packaging.
How Shandong Hengsheng Crafts Co., Ltd. satisfies complex global procurement requirements.
We work as a direct manufacturer featuring independent research, design, and production capabilities. We have over 40 years of production experience, tailoring glass shapes, volumes, and barrier specs to customer specifications.
Located in Shandong, the glass manufacturing center of China, we benefit from immediate proximity to key raw materials (silica sand, soda ash) and major deep-water ports (Qingdao Port). This enables competitive pricing and reliable transit schedules.
Global regulatory developments are moving away from single-use plastics. UV-blocking glass bottles provide a fully recyclable, chemically inert solution that satisfies global sustainability standards.
Our factory employs more than 300 experienced craftsmen operating automated production lines. We conduct thorough quality checks at every phase, from raw material inspection to final packaging, helping ensure consistent output.
Our R&D team consists of more than 10 senior designers releasing over 20 new designs annually. Our export sales staff are experienced in handling foreign trade regulations and processes, managing project requirements from initial design to logistics.
Through coordinated production and sales processes, our glassware is exported to over 30 countries and regions. We support global businesses with fast shipping, reliable lead times, and comprehensive customer service.
Providing specialized glassware processes that match your product requirements.
Equipped with computer-controlled automatic forming, annealing, and processing machinery to handle high-volume B2B packaging runs.
We offer a wide range of standard inventory options along with bespoke mold capabilities, providing shapes tailored to your product portfolio.
Collaborate directly with our design department. We turn your product concepts and 3D renderings into high-performance glass packaging.
We supply clients in North America, Europe, Asia, and other regions, adapting our packaging and delivery to match local commercial practices.
Meeting international quality benchmarks to support seamless importing and distribution.
We perform rigorous physical and chemical testing to ensure our glassware complies with global standards. We use spectrophotometer analyses to verify light transmission profiles, ensuring each batch meets the required protective standards.
We offer flexible container consolidation options to minimize shipping costs for global businesses. We provide comprehensive import documentation, including custom clearance documents, Certificates of Analysis (COA), and third-party lab certifications.
Technical and commercial answers to common inquiries from procurement managers and brand developers.
Our UV-blocking glass packaging is engineered to block up to 99% of electromagnetic radiation across ultraviolet ranges (UV-C, UV-B, and UV-A, ranging from 100nm to 400nm). It also filters out high-energy visible light (HEV) up to 450nm, while allowing selective transmission of non-degrading infrared and visible light depending on your requirements.
For standard stocked shapes, the MOQ is 20,000 units with a lead time of 15 to 20 days. Custom OEM/ODM designs requiring custom molds typically have a tooling phase of 20 to 30 days, followed by production lead times of 30 to 45 days depending on run size.
Yes, our raw materials are tested for food safety and environmental compliance. We provide complete documentation for FDA (US Food and Drug Administration) and REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) regulations, ensuring seamless importing into North America and European territories.
We offer extensive surface treatments, including chemical frosting, electrostatic spray coating, high-temperature silk-screen printing, metallic hot stamping, and custom labeling. These treatments are applied without compromising the UV-blocking capabilities of the base glass.
