Lecos
Engineered to comply with ISO 9001 and USA FDA pharmaceutical packaging standards. Features robust thermal stability, superior chemical inertness, and light-filtering capabilities.
Lecos Glass (Lecospack) has been dedicated to the luxury and clinical-grade glass packaging industry for over 10 years. We specialize in producing innovative wholesale glass bottles and jars for cosmetics, premium perfume formulations, specialized personal care products, essential oils, and sophisticated candle installations. We pride ourselves on being true engineering partners, offering bespoke design services to our global clients.
Essentially, we offer an extensive portfolio of glass bottles, jars, custom closures, and precision spray accessories. Our major core collections include:
Lecospack provides complete, high-quality, and cost-effective glass cosmetic packaging solutions optimized for international brand DNAs. Every batch of glass undergoes strict quality inspections (stress tests, internal pressure tests, lead and cadmium extraction tests) to ensure chemical compatibility with complex cosmetic active ingredients. We offer complete custom decoration processes, including:
For a premium matte tactile experience and diffused light transmission.
Applying reflective metallic layers for luxurious modern branding.
Providing custom color gradients that block harmful UV spectrums.
Ensuring sharp text display and strong adhesion under wet conditions.
An industry whitepaper evaluating photochemical protection, supply chain optimization, and automated Chinese manufacturing capabilities for global cosmetic and botanical brands.
Cobalt blue glass is not merely an aesthetic choice; it serves a critical packaging function. Cobalt glass is produced by adding cobalt oxide during the silica melting process. This creates a dense deep-blue matrix that absorbs light wavelengths in the most damaging UV spectrums (UV-A and UV-B: 290nm to 400nm).
By filtering this light, blue glass prevents the photodegradation of sensitive ingredients such as organic essential oils, ascorbic acid, retinol, and plant-derived extracts, extending product shelf life and efficacy.
While amber glass offers slightly better protection at the lower end of the visible light spectrum, cobalt blue glass strikes a balance between UV protection and premium brand appeal.
Brands looking for clinical positioning choose blue glass to signal scientific efficacy and purity. Crucially, cobalt blue allows visual checks of fill levels and formulation stability while blocking harmful UV radiation.
A high-quality spray bottle relies on the performance of its closure mechanism. Lecospack collaborates with top-tier pump manufacturers to pair our custom bottles with fine-mist sprayers, atomizers, and lotion pumps.
We verify thread engagement (GPI standards such as 18/410, 18/415, and 20/400) and pump discharge volumes (typically 0.1ml to 0.22ml per stroke) to ensure a smooth, fine mist delivery for face sprays, hair oils, or disinfectants.
Our glass packaging complies with the United States Pharmacopeia (USP) Class III and European Pharmacopoeia (EP) specifications for chemical durability and thermal resistance.

Operating out of China's advanced industrial packaging hubs, Lecos Glass offers a reliable balance of cost efficiency, integrated supply chains, and high customization capabilities.
Our production facilities utilize automated bottle-blowing machines (I.S. machines) to maintain uniform glass distribution. This reduces bottom-heavy glass anomalies and thin sidewalls that lead to transit breakage.
Addressing the procurement needs of global logistics networks, including compliance, packaging security, and supply chain continuity.
Lecospack offers DDP (Delivered Duty Paid), CIF, and FOB shipping options. We manage all export documentation, custom clearance clearances, and phytosanitary certificates, ensuring a smooth transition through European, North American, and Asian custom ports.
We enforce a strict AQL (Acceptable Quality Limit) 1.5/2.5 system. Our quality control engineers monitor production from hot-end forming to cold-end inspection, utilizing optical cameras to detect cracks, bubbles, and particulate inclusions.
We work directly with major cosmetic brands and packaging design houses. Our team manages the complete process, including structural glass design, FEA (Finite Element Analysis) stress testing, accessory color matching, and protective outer carton design.
At Lecos Glass, we believe our consistency sets us apart. We focus on maintaining high standards, competitive pricing, and excellent service across our entire operations.
