Lecos Glass has been dedicated to the glass packaging industry for over 10 years with our innovative wholesale glass bottles and jars for cosmetics, perfume, personal care, essential oils, and candle jar glass packaging. We pride ourselves on offering bespoke glass bottles tailored to our clients' precise branding DNA.
Lecospack provides professional glass cosmetic packaging solutions to worldwide customers. With years of experience in the field, we are capable of providing innovative, stable quality, and cost-effective packaging. The quality of our glass products is strictly controlled, winning the favor of both domestic and foreign customers, working with many global brands directly and indirectly. We also offer all kinds of customized deep processing for glass bottles, such as frosting, electroplating, spraying, decal, and silkscreen printing.
Utilizing high-grade soda-lime silica and borosilicate glass raw materials, processed under ISO 9001 and ISO 15378 standard guidelines to ensure flawless clarity, density, and chemical stability.
Direct from-factory pricing structures optimized through automated IS machine manufacturing lines, lowering material waste and energy usage to pass on cost benefits to global sourcing managers.
Dedicated 24/7 account management from conceptual design CAD drafting, rapid 3D prototyping, customized mould processing, to strict compliance with international customs shipping.
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.

In the high-performance skincare and cosmetic industry, selecting the appropriate glass chemistry is vital for product stability, shelf life, and brand equity. Not all glass is fabricated equal. At Lecos Glass, we specialize in high-end Type III soda-lime glass optimized for cosmetic formulations, alongside Type I borosilicate formulations for highly volatile or acidic active ingredients.
Type III glass offers exceptional hydrolytic resistance, meaning it will not leach alkaline compounds into your luxury cosmetic oils, creams, or serums. It exhibits high density, giving the 100ml glass bottle that coveted heavy weight and optical brilliance similar to crystal. For brands formulating clean beauty lines without heavy artificial preservatives, the chemical inertness of Type III glass ensures the formula does not interact with the packaging over a standard 2-year storage lifecycle.
China remains the powerhouse of global glass container production, driven by massive regional raw material clusters in Xuzhou, Shandong, and Guangdong provinces. This localization allows Lecos Glass to source primary materials—such as high-purity silica sand, soda ash, and limestone—locally, shielding international buyers from geopolitical supply chain shocks.
Furthermore, Chinese factories have systematically transitioned from legacy manual blowing processes to automated Individual Section (IS) machine configurations. By employing double-gob and triple-gob processes, Lecos Glass produces up to 300,000 flawless units daily. These automated systems are paired with optoelectronic camera testing lines that scan every single 100ml bottle for microscopic bubbles, cracks, wall thickness variations, and neck thread deviations before they reach the packing bay. This level of scaling ensures competitive costs per unit while matching European aesthetic tolerances.
| Specification Parameter | Tolerance / Standard Range | Testing Protocol |
|---|---|---|
| Vertical Load Resistance | > 1200 N (Newton force) | Hydraulic Crush Tester |
| Thermal Shock Resistance | ΔT ≥ 42°C (No fractures) | Rapid Temperature Dip Water Bath |
| Neck Finish Tolerance (GPI/GCMI) | ± 0.25 mm (24/410, 18/415 standard) | Go/No-Go Gauge Inspection |
| Hydrolytic Stability | Compliant with ISO 4802-1 | Acid-base titration on inner glass surface |
| Lead (Pb) & Cadmium (Cd) Leaching | < 0.1 mg/L (FDA compliant) | Atomic Absorption Spectrophotometry (AAS) |
For international buyers in North America, Western Europe, and Japan, regulatory compliance is a major operational risk. Sourcing from uncertified companies can lead to port-of-entry impoundments or customer product recalls. Lecos Glass solves this problem by strictly adhering to FDA CFR Title 21 requirements for food and cosmetic contact materials, alongside EU Directive 94/62/EC limiting heavy metals to under 100ppm.
Our quality assurance department operates under the Acceptable Quality Limit (AQL) framework, specifically using AQL 1.0 for major defects (such as thin glass spots or structural cracks) and AQL 2.5 for minor defects (such as minor surface bubbles or light scuffs). We conduct rigorous torque tests, drop tests, and chemical compatibility assessments. Sourcing managers are provided with full Certificates of Analysis (COA) and material traceability certificates for every single shipment, ensuring seamless custom clearance and brand safety.
Standard glass bottles can feel generic; custom decoration transforms a simple glass vessel into a luxury brand tactile experience. Lecos Glass offers state-of-the-art decoration processes in-house. These include acid-etch frosting for a smooth matte feel, vacuum electroplating for metallic gold/silver/bronze finishes, and precision multi-color silk screen printing using lead-free organic or ceramic inks. Our ceramic ink technology bonds physically with the glass at temperatures over 600°C, rendering the print scratch-resistant and highly resilient against chemical degradation from essential oils.
The 100ml capacity (approx. 3.4 fluid ounces) serves as the "golden threshold" across personal care, cosmetics, and OTC pharmaceuticals. The primary driver is compliance with international aviation safety regulations: 100ml is the maximum limit for liquids, gels, and aerosols in passenger carry-on luggage. Sourcing 100ml containers allows your consumers to travel with premium serums, toners, and oils without repackaging.
Furthermore, from an active-ingredient perspective, 100ml offers the ideal volume for typical daily application over 30 to 60 days. This duration aligns perfectly with the efficacy lifecycle of most skincare formulations, ensuring the product is consumed before atmospheric exposure leads to oxidation or loss of activity.
Global brands are prioritizing environmental sustainability in response to consumer demand and legislative actions, such as the EU Packaging and Packaging Waste Regulation. Two key manufacturing trends are shaping the future of 100ml glass packaging:
1. PCR (Post-Consumer Recycled) Integration: Sourcing bottles with 10% to 50% PCR glass reduces carbon footprints. However, PCR glass introduces slight color shifts (often yellow/green hues). Sourcing managers must work with factories like Lecos Glass to adjust clarification agents and maintain visual consistency.
2. Lightweighting (NNPB Process): Using Narrow Neck Press and Blow (NNPB) technology, we reduce bottle weight by up to 20% while maintaining thermal and pressure resistance. This translates to lower shipping emissions and reduced carbon taxes for importers.
