Explore our flagship collection of high-precision glass bottles and jars designed for cosmetics, personal care, and specialized oil formulations.
A macroeconomic and structural breakdown of raw materials, market demands, and technical advancements.
The global glass packaging industry is witnessing a structural transition. Brands are rapidly abandoning plastics in favor of inert glass alternatives to address environmental regulations and consumers' demands. A 1 Ounce (30ml) glass vial serves as the gold-standard volume for highly concentrated cosmetic active ingredients, premium serums, essential oils, and dermatological formulations.
This volumetric size minimizes product oxidation and limits preservative requirements. As a result, B2B procurement managers globally search for reliable partners in China who can deliver consistent structural integrity, zero-chemical-leaching guarantees, and custom post-processing designs that represent their brand identity.
Sourcing managers target China-based manufacturers to leverage advanced automated production, highly skilled engineering, and cost-effective raw materials. The criteria for picking a vendor have shifted from price-only variables to long-term reliability and documentation compatibility.
Modern suppliers must maintain compliance certificates, strict chemical-resistance standards (such as USP Type I, II, or III glass composition), and offer versatile custom molds. This balance minimizes total cost of ownership (TCO) while guaranteeing high filling line efficiency and zero breakage rates during transit.

We pride ourselves on being good at offering bespoke glass solutions tailored to our clients' precise branding needs.
We manage a comprehensive portfolio of glass packaging and accessories. Although we feature hundreds of distinct molds, our collections focus highly on key cosmetic formats:
Lecospack provides professional glass cosmetic packaging solutions to worldwide customers. Armed with years of experience, we deliver innovative, stable quality, and cost-effective packaging aligned with each client's unique brand DNA.
Our rigorous quality-control processes have earned the trust of domestic and international brands. We work with leading names in beauty and personal care both directly and indirectly. In addition, we offer deep custom decoration services for glass bottles:
Our business foundation is built on three core pillars designed to drive global brand success.
Uncompromising manufacturing tolerances, thick bases, and strict chemical resistance metrics across every production run.
Strategic supply chain positioning in China allows us to pass raw material savings and efficiency directly to clients.
End-to-end B2B support, from custom conceptual design and rapid prototyping to international delivery logistics.
Our company is built on a solid foundation of deeply held values that set us apart, steer our actions, and infuse every aspect of our corporate culture. These values are not just words; they are the principles that guide how we operate daily. Central to our business practices are our unwavering commitment to social responsibility, adherence to ethical standards, and steadfast support for universal human rights.

A detailed engineering overview mapping glass compositions against B2B packaging performance criteria.
| Performance Indicator | USP Type I Borosilicate Glass | USP Type III Soda-Lime Glass | PCR (Post-Consumer Recycled) Glass |
|---|---|---|---|
| Hydrolytic Resistance | Extremely High (Acid/Neutral/Alkaline resistance) | Moderate (Ideal for neutral liquids/oils) | Variable (Dependent on post-purification sorting) |
| Thermal Shock Threshold | Up to Δ 150°C | Up to Δ 60°C | Up to Δ 75°C |
| Brimful Volumetric Tolerance | ± 0.25 ml | ± 0.50 ml | ± 0.60 ml |
| Light Transmission Barrier | High (When tinted Amber or Cobalt) | High (With external UV shielding) | Excellent (Natural green/amber coloration) |
| Carbon Footprint Index | High (Requires higher melting point) | Moderate | Extremely Low (Up to 35% reduction in CO2) |
As a pioneering force in the Chinese glass manufacturing ecosystem, we are continuously pushing the envelope of ecological design. Over the next five years, we are scaling our electric-hybrid furnaces to reduce dependence on fossil fuels, cutting carbon dioxide output by an estimated 20%.
Simultaneously, we are refining lightweight glass technology. By altering wall thickness distribution while strengthening structural hotspots, we are engineering 1 Ounce glass vials that weigh 15% less but retain the exact vertical load strength. This reduces shipping emissions and overall logistic costs for our international customers.

Ensuring risk-free international procurement for brands in Europe, North America, and globally.
We supply critical regulatory documentation to guarantee a smooth import process. Every batch is supported by comprehensive documentation, including:
Long-distance sea and air shipping requires robust packaging strategies. At Lecos Glass, we employ specialized, thick-walled corrugated outer cartons coupled with precision-molded heat-shrinkable plastic trays.
To prevent friction and glass-on-glass scratching during transport, we separate fragile custom-decorated vials with individual dividers. For hazardous or highly pressurized materials, we provide UN-rated outer crates that ensure secure transit and delivery.

Our pricing structures are determined by a combination of key factors: total volume, the raw glass material specification (Type I vs Type III), and the complexity of customized post-processing (e.g., custom frosting, metallic electroplating, and multicolor silk-screen printing). Please get in touch with our sales team to request our latest, volume-tiered B2B pricing catalogs.
Yes, we require all international orders to have an ongoing minimum order quantity. This MOQ helps balance automated setup costs with low unit prices. Typical MOQs range from 5,000 to 20,000 units depending on the custom mold required. For smaller trial orders, please reach out to check our current off-the-shelf inventory availability.
Absolutely. We support international customs clearance and cosmetic safety reviews by providing Certificates of Analysis (CoA), Certificates of Conformance (CoC), raw material safety datasheets (MSDS), and origin certificates.
For standard prototyping and mock samples, the average turnaround is 7 days. For mass production runs, lead times typically fall between 20 to 30 days after receiving deposit confirmation and final artwork approval. We always strive to optimize our production queues to meet your launch deadlines.
We accept standard corporate bank telegraphic transfers (T/T), Western Union, and PayPal. Our typical payment structure is a 30% deposit in advance, with the remaining 70% balance paid against copies of the Bill of Lading (B/L).
We stand behind our materials and craftsmanship. Our QA program tests for wall thickness uniformity, internal stress, and cap torque compliance. If any batch fails to meet established tolerances, our dedicated customer support team will work quickly to resolve the issue to your satisfaction.
We package all products in heavy-duty, multi-layered export cartons. Pallets are systematically wrapped and strapped to guarantee structural integrity during ocean voyages and customs handling.
Shipping costs depend on the transport mode you select (express air freight, LCL ocean freight, or full container load). Ocean freight remains the most cost-effective solution for large volumes, whereas air shipping offers rapid delivery times. Our logistics team provides precise freight quotes based on total dimensions, gross weight, and destination port.
