Lecos
Explore our state-of-the-art custom glass solutions optimized for high hermetic sealing parameters, barrier protection, and aesthetics.
Lecos Glass has been dedicated to the glass packaging industry for over 10 years, delivering innovative wholesale glass bottles and jars specifically designed for cosmetics, perfume, personal care, essential oils, and candle jar glass packaging. We pride ourselves on offering bespoke glass bottles tailored to the precise DNA of our global clients.
We boast a wide catalog of glass bottles, jars, and tailored accessories. Our extensive, high-end collections include:
An analysis of moisture vapor transmission rates (MVTR), polymer liners, and glass neck thread geometry.
Unlike plastic containers (PET, PP, Acrylic) which are prone to microscopic organic migration and high oxygen transmission rates over time, glass stands as an inert, impermeable barrier. At Lecos Glass, we prioritize Type III and Type I Borosilicate glass formulations. These materials undergo precision annealing in computer-controlled lehrs to eliminate internal thermal stresses. The resulting physical structures yield a chemical resistance level (Class HGB1 under ISO 719) that prevents alkaline ion elution, preserving active skincare and pharmaceutical compounds indefinitely.
An airtight lid is not defined solely by how tight the cap is spun. The critical element is the liner composition and the torque retention of the container finish. We use premium food-grade and medical-grade gaskets, including:
Proper sealing depends on precise mechanical interactions. We manufacture neck finishes in strict accordance with the Glass Packaging Institute (GPI) and European Glass Container Manufacturers Association (FEVE) standards. By maintaining tight tolerance controls on dimensions like the outer thread diameter (T), bead diameter (E), and neck interior (I), we ensure even compression across the entire sealing gasket.
| Standard Designation | Tolerance Limit (mm) | Recommended Application | Hermetic Performance |
|---|---|---|---|
| GPI 400 (Shallow Continuous Thread) | ±0.25 | Standard cosmetic jars, dry powder storage | High (with EPE liners) |
| GPI 410 (Medium Continuous Thread) | ±0.20 | Viscous serums, lotion dispensers | Excellent (with liquid pump integration) |
| GPI 415 (Deep Continuous Thread) | ±0.18 | Low-viscosity volatile solvents, droppers | Ultra-High Hermetic Seal |
How Lecos pack delivers reliability across all international manufacturing metrics.
Lecospack provides professional glass cosmetic packaging solutions to worldwide customers. We design stable, high-performance packaging customized to each brand's unique DNA. Beyond raw glass blowing, we offer advanced, in-house deep-processing decorative options:
Addressing distinct chemical compatibility, UV protection, and storage lifetime requirements across global markets.
Active ingredients like Retinol, Vitamin C, and Peptides are highly sensitive to oxygen degradation and light exposure. Our thick-walled glass jars combined with airtight inner lids provide complete barrier protection. Specialized dark amber or frosted UV-shield coatings block high-energy visible (HEV) and ultraviolet light, preserving formula stability.
Terpenes and essential plant extracts can dissolve standard plastic materials and escape through inferior cap linings. Lecos Glass manufactures high-precision 5ml to 150ml dropper bottles with chemically inert glass dropper pipettes and PTFE-lined caps. This ensures zero leakage during air cargo transit and long shelf lives for volatile formulations.
Compliance is paramount in healthcare packaging. Our production lines manufacture Type I glass containers that conform to USP <660> and EP 3.2.1 guidelines. Equipped with pharmaceutical-grade airtight lids and tamper-evident designs, they prevent contamination and ensure sterile environments for clinical preparations.
Our manufacturing center blends traditional craftsmanship with Industry 4.0 automation. Our facilities feature advanced Individual Section (IS) forming machines operating alongside automated raw material dosing systems, ensuring consistent container weight and wall thickness across production runs.
We use automated inline inspection technologies (optical cameras and laser scanners) to check every jar and bottle. This system detects micro-cracks, air bubbles, and cosmetic defects at production speeds, allowing us to maintain a low defect rate before packaging.
This automated production model enables us to offer competitive pricing and reliable supply lines, helping brands navigate volatile demand and shipping schedules.
Developing next-generation sustainable materials while meeting international regulatory standards.
Lecos Glass is committed to advancing eco-friendly glass packaging. Our R&D efforts focus on two key initiatives:
We ensure our products comply with local and regional standards across all destination markets. This includes:
