Lecos
Highly durable glass containers engineered for maximum stability, minimal leachables, and aesthetic packaging design.
Decade-long experience in supplying professional-grade cosmetic and personal care glass packaging solutions globally.
Lecos Glass has been dedicated to the glass packaging industry for over 10 years. We specialize in producing innovative wholesale glass bottles and jars customized for cosmetics, perfume, personal care, essential oils, and candle glass packaging. We pride ourselves on offering bespoke glass bottles that align directly with our clients' brand DNA and operational scale requirements.
Whether you require fancy dropper bottles, Boston Round profiles, specialized glass skincare containers, premium closures, cosmetic jars, or custom-molded fragrance bottles, Lecospack ensures consistency, premium material grade selection, and flawless surface treatable qualities.
We provide advanced customization techniques to translate visual design into tactile consumer luxury. Glass container modification is performed in controlled post-processing facilities ensuring maximum adhesion and wear-resistance. Our capabilities include:
Our performance is verified by key manufacturing indicators and quantitative laboratory standards.
Clear glass droppers manufactured by Lecos Glass utilize Type III soda-lime-silica glass (or Type I high-borosilicate glass upon request). This ensures chemical inertness, preventing formula degradation, gas permeability, and product-packaging reactions. The glass structure retains structural integrity against acidic skincare ingredients (such as high-concentration Vitamin C or Salicylic Acid) and organic solvents common in high-performance cosmetic oils.
Operational pillars supporting reliable high-volume cosmetic and clinical supplies.
We source ultra-pure sand and silica, maintaining a controlled melt atmosphere. The result is crystal-clear glass that shows the true color of your cosmetic serum without green tint deviation or inclusions, meeting strict cosmetic industry specifications.
Our advanced furnace management and fully automated forming machinery minimize fuel waste and improve yield. These internal savings are passed directly to our commercial partners to maintain target production costs.
Lecos Glass acts as an extension of your technical team. From customized CAD drafting, sample preparation, and physical performance testing to final transport documentation, we ensure your launch deadlines are met safely.
Analysis of changing consumer habits, formulation trends, and supply chains in global premium packaging.
Modern skincare formulations have evolved past simple oil-in-water emulsions. Contemporary products rely on highly active organic molecules—such as L-ascorbic acid, niacinamide, peptides, retinol, and botanical complexes. These compounds are sensitive to UV exposure and chemical interactions with packaging materials.
Clear glass dropper bottles provide transparency, allowing customers to check product levels and purity, but they require glass with high hydrolytic resistance to prevent alkaline ions from leaching into water-based serums and changing their pH stability.
The global glass packaging market is navigating rising energy costs, carbon emissions requirements, and raw material volatility. Standard glass manufacturing is energy-intensive, requiring high temperatures to melt silica.
To mitigate supply chain risks, Lecos Glass operates optimized heat-recovery furnace setups and localized logistics centers. This helps control shipping lead times and price fluctuations, providing global brands with a reliable source for custom clear dropper bottles.
Ensuring cross-border compliance with FDA, EU, and regional chemical safety standards.
Cosmetic and clinical preparations must comply with strict safety rules regarding heavy metal migration. Our glass containers pass USP <660> (Physicochemical Tests for Glass Containers) and European Pharmacopoeia (EP 3.2.1) tests. Additionally, we provide documentation verifying compliance with heavy metal limits (lead, mercury, cadmium, hexavalent chromium) under CONEG/TPCH regulations.
A dropper bottle is only as reliable as its dispensing assembly. Lecos Glass manufactures customized rubber bulbs using NBR (nitrile butadiene rubber), silicone, and bromobutyl elastomers. These materials are tested to ensure they do not swell, degrade, or release compounds when exposed to essential oils and volatile cosmetic solvents.
For applications such as concentrated essential oils, liquid supplements, and pharmaceutical preparations, packaging safety is paramount. We supply ISO 8317 and 16 CFR Part 1700.20 certified Child Resistant Packaging (CRP) dropper caps, ensuring compliance with global consumer protection regulations.
Social responsibility, ethical standards, and supporting universal human rights are the foundations of our culture.
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.
We are also dedicated to protecting the environment and making a positive impact in the communities where we live and work. We believe in fostering creativity and innovation, celebrating and embracing the richness of diversity, and treating our employees with the utmost respect and care, as if they were members of our own family. By upholding these values, we ensure that our company remains a responsible, ethical, and inspiring place to work.
Our structured development plan to reduce environmental impact and improve product performance over the next decade.
We are increasing the proportion of Post-Consumer Recycled (PCR) glass in our green and amber dropper bottles, targetting a minimum of 30% recycled content without compromising hydrolytic resistance or material stability.
We are preparing to convert our main furnaces to hybrid oxy-fuel combustion systems. This process uses oxygen instead of ambient air to burn fuel, reducing nitrogen oxide (NOx) emissions and overall fuel consumption during melting.
Our long-term goal is to build closed-loop systems with key brand partners, collecting glass waste directly from regional distribution channels to reprocess it into new packaging.
Technical and logistics details for international buyers and supply chain managers.
Our prices are subject to change depending on supply, raw material rates (soda ash, sand, energy index), and other market factors. We will send you an updated price list after your company contacts us for further information.
Yes, we require all international orders to have an ongoing minimum order quantity. For standard bottles, this typically starts at 10,000 to 20,000 units. If you are looking to resell in smaller quantities, please contact us through our website to check available stock options.
Yes, we can provide most documentation including Certificates of Analysis / Conformance, heavy metal compliance sheets, raw material declarations, Insurance documentation, Certificates of Origin, and standard export documents.
For custom samples, the lead time is about 7 to 14 days. For mass production, the typical lead time is 20-30 days after receiving the deposit payment and final approval of the structural specs. We work with clients to accommodate tight launch schedules where possible.
You can make payments to our verified corporate bank account, Western Union, or PayPal. Our standard terms are a 30% deposit in advance, with the 70% balance paid against the copy of the Bill of Lading (B/L).
We warranty our materials and workmanship against functional defects. Our commitment is to address and resolve any issues, such as breakage or leakage, to our customer's satisfaction. If defects occur, we investigate to identify the root cause and provide replacements or credits.
Yes, we use durable export packaging, including custom pallets and reinforced partition boxes. We also use specialized packaging for sensitive shipments. Non-standard packaging requirements may incur an additional charge.
Shipping costs depend on the delivery method. Express delivery is fastest but most expensive. Sea freight is usually the most cost-effective solution for larger shipments. Exact freight rates depend on cargo volume, weight, and the final destination port.
