Explore our top-tier manufacturing lines and high-performance equipment optimized for heavy industrial and field operations.
Deep dive into standard compliance, raw material metrics, and why glass remains the gold standard for global food supply chains.
In the modern consumer packaging ecosystem, food-grade glass bottles serve as the premier choice for preserving product purity, extension of shelf-life, and safeguarding taste profiles. Unlike plastic or metallic alternatives, glass is chemically inert, preventing any risk of phthalate leaching, Bisphenol-A (BPA) transfer, or flavor-compromising oxidation.
Our state-of-the-art production leverages advanced raw materials—including silica sand, soda ash, limestone, and high-percentage clean cullet (recycled glass)—melted at temperatures exceeding 1500°C. This meticulous process ensures a container that provides complete resistance to acids, carbonation pressure, and extreme sterilization protocols.
| Parameters | Industry Standard | Our OEM Target Spec |
|---|---|---|
| Lead & Heavy Metals | < 100 ppm | Strictly 0 ppm (Lead-Free) |
| Thermal Shock Resistance | Δ 40°C max | Δ 60°C to 120°C (Sterilizable) |
| Hydrolytic Resistance | Class III / Class II | Class HGB1 (High Acid Resistance) |
| Internal Pressure Rating | Up to 3.0 Bar | Custom engineered up to 10.0 Bar |
| Annealing Quality | Real stress grade < 4 | Grade 1 to 2 (Optimal temper) |
From digital concept modeling to high-throughput IS machine operations, discover how we build market-differentiated glass packaging solutions.
We convert ideas into reality. Using industrial-grade 3D CAD modeling, structural finite element analysis (FEA), and fast 3D polymer printing, we test volumetric capacity and sealing compatibility prior to hard-tooling investment.
Our lines support the Narrow Neck Press and Blow (NNPB) technology. This advanced forming technique allows for optimization of glass weight distribution, reducing total container mass by up to 20% while reinforcing wall strength.
Enhance on-shelf visual identity. We offer extensive custom finishing options: high-fire silk screen printing, multi-color organic screen printing, frosting, hot stamping, UV metallic lacquer coating, and intricate custom embossing.
Different food products demand specialized material configurations and structural properties. Our engineered glass catalog addresses distinct applications:
Operating from the coastal industrial hubs of China, we capitalize on integrated supply networks. This permits competitive tooling development, fast mold changes, and lower overall production costs.
Our strategic position near container ports (such as Xiamen and Ningbo) translates to seamless ocean transport and lower transit times. With access to rich raw material inputs, state-supported power grids, and advanced mechanical technicians, our factory delivers high-speed output and strict batch consistency.
Combining heavy industrial supply chains with agile, high-performance consumer manufacturing structures.
Xiamen Yuelei Sports Co., Ltd. operates a state-of-the-art manufacturing facility in Xiamen, China, covering 1,600 square meters and staffed by approximately 30 skilled professionals. We specialize in OEM and ODM for outdoor apparel, utilizing advanced production equipment and rigorous quality control processes to ensure every product meets the highest standards. Our factory is equipped to provide comprehensive customization services, allowing us to tailor our offerings to the specific needs of our clients.
Xiamen Yuelei Outdoor Sports Co., Ltd., where LKVER is based, began selling ski jackets and wetsuits on AliExpress in 2021. Due to a surge in orders and our suppliers' inability to produce on time, the company decided to establish its own production workshop under the LKVER brand. As the workshop was built, Yuelei Outdoor Sports Co., Ltd. expanded its wholesale trade model and now operates two Alibaba International platforms and one AliExpress store. Every year, we handle production and customization for a large number of new and returning customers.
Get professional guidance on minimum order quantities, compliance certifications, tooling investments, and customization protocols.
For standard glass formulations (High Flint, Flint, Amber), our minimum order quantity typically ranges between 30,000 to 50,000 units per batch. This is dictated by the massive material throughput required to maintain temperature stabilization in the glass furnace during automated IS machine runs.
Our glass compositions undergo regular batch testing conducted by third-party laboratories (SGS / TUV). We comply with US FDA Title 21 CFR 175.300 and EU Regulation (EC) No 1935/2004, confirming that heavy metal content (Lead, Cadmium, Mercury, Hexavalent Chromium) is below critical limits.
Once design drawings are finalized, fabricating trial molds takes approximately 15 to 20 days. Physical sample runs follow within 7 to 10 days. Upon sample approval, final production molds are manufactured within 20 days, allowing for total pilot production in under 50 days.
Yes. Our high thermal endurance glass jars are designed to handle hot filling, pasteurization, and retort autoclave sterilization up to 121°C (250°F), provided that cooling rate controls are maintained to prevent thermal shock stress.
Premium outdoor weather gear, survival suits, and specialized hulls manufactured under strict ISO guidelines.
