Selecting the right glass vials and caps ensures proper storage, presentation, and performance for every product type.
By Corey Knowles
When selecting the best glass vials with caps for your products, it’s essential to consider the material, finish, closure, and design features that will both protect product integrity and enhance shelf appeal. As a U.S. manufacturer with over 80 years of experience, we’ve helped numerous companies in the cannabis, essential oils, skincare, and cosmetics industries find the ideal vial and cap combination to ensure optimal product presentation, preservation, and user experience.
Common Vial Sizes and Finishes
Our tubular glass vials range from 7.75 mm to 29 mm in diameter and 19 mm to 203 mm in length. These dimensions enable us to produce small glass vials wholesale, suitable for a range of applications, from 1 ml essential oil samples to 15 ml and 30 ml cosmetic serums. Finishes include screw thread, crimp, patent lip, display, and fire-polished shell styles, each selected for the type of closure and dispensing control your product requires.
Comparing Glass Types: Borosilicate vs. Soda-Lime
Borosilicate glass (Type I) is preferred for products that demand superior chemical resistance and thermal stability, such as essential oils and serums. It resists pH changes and temperature shifts. Soda-lime (Type III) glass offers reliable strength and clarity for general-purpose packaging, including cannabis pre-roll and flower storage. Both options maintain clarity and integrity through repeated handling and shipping.
Cap and Closure Options
We offer a range of cap-and-closure styles to fit your application. Screw-thread finishes (8-425 through 24-400 GPI) provide a tight, reliable seal for oils, tinctures, and samples. Crimp and patent lip designs support droppers, atomizers, or decorative tops in skincare and perfume packaging. For cannabis use, child-resistant closures ensure safety compliance while remaining easy for adults to open.
Benefits of Tubular Glass Vials
Every vial we produce is formed through tubing conversion rather than molding. This process allows for exceptional consistency in wall thickness, weight, and optical clarity. The result is a lightweight yet durable vial ideal for precise filling and clean product presentation. Tubular vials are also well-suited for automated filling lines and labeling systems.
Custom Manufacturing and Screen Printing
Custom manufacturing is one of our core capabilities. We can produce vials to your exact specifications in small or large runs, with options for silk-screen printing, and branding. This enables your packaging to reflect your identity while maintaining precise fit and finish with the chosen closure.
Smell-Proof and Airtight Storage
For cannabis and aromatherapy applications, maintaining aroma integrity and preventing odor leakage ensures users enjoy effective, long-lasting product experiences. Our airtight seals and properly matched screw-thread caps keep odors contained and preserve freshness and potency. When paired with amber or cobalt glass, these closures also safeguard light-sensitive ingredients from degradation.
Matching Vial Dimensions to Product Viscosity
Thin essential oils flow easily, while thicker skincare serums require wider openings or droppers. Matching the vial neck size and finish to the viscosity of your product ensures smooth dispensing and minimizes waste. For example, 10 ml glass vials with screw caps are excellent for most medium-viscosity formulas.
Color Options and UV Protection
Clear glass showcases the product’s color and clarity, making it ideal for display purposes. Amber glass filters UV light, making it the preferred choice for photosensitive essential oils, botanical extracts, and some skincare formulations.
Factory-Direct Advantages
All our vials are manufactured in our Paso Robles, California, facility. By purchasing directly from the factory, customers receive consistent quality, fast lead times, and low minimum order quantities. We offer same-day shipping for stock items and worldwide service.
Quality Assurance and Inspection Standards
Each vial undergoes annealing and inspection stages to ensure its structural integrity and dimensional accuracy. We maintain a rigorous quality management system focused on meeting customer specifications and delivering dependable performance in every order.
