Our wholesale glass bottle lids are sold separately so you can match the right closure to every bottle in your lineup. Choose from lightweight polypropylene (PP) caps in black or white, HDPE tamper-evident dropper caps for Euro-neck bottles, or aluminum caps in black or silver for a more premium shelf presence. All options are continuous-thread closures designed to fit standard neck finishes — available in sizes running from 10ml up to 500ml.
Prefer plastic? Our plastic bottle caps come in black and white PP with a clean, secure fit for everyday product lines. Want a more upscale look? The aluminum bottle caps in black or silver add a polished finish that works well for cosmetics, tinctures, and premium retail products. Both styles pair with the glass bottles in our catalog, and you can mix closures across your product line without committing to one style for everything.
Choosing the Right Glass Bottle Lid for Your Product
The lid is often the last thing brands think about — and the first thing customers touch. PP caps are the practical choice: lightweight, easy to apply, and cost-effective for high-volume runs. HDPE tamper-evident dropper caps are the right call for Euro-neck bottles — they include a built-in tamper band and work well for tinctures, pharmaceutical-style packaging, and any application where tamper evidence matters. Both work well for serums, carrier oils, cleaning products, and liquids that don't need a premium unboxing feel. Aluminum caps are a different story. They photograph better, feel heavier in hand, and immediately signal quality. If your product sells on aesthetics — skincare, artisan blends, boutique wellness — the aluminum finish earns its small premium.
All lids are sized by neck finish. Most of our glass bottles use standard continuous-thread finishes (18-400, 20-400, 24-400, 28-400, 38-400), so matching a cap to a bottle is straightforward. If you're not sure which finish your bottle takes, the product page for each bottle lists compatible closure sizes. When in doubt, order a sample first — our sample collection makes it easy to test fit and feel before committing to a bulk order.
Industries and Products That Use Our Bottle Caps
Glass bottle lids are a core purchase for a wide range of product categories. Cosmetic and skincare brands use them to seal serums, facial oils, and toners. Tincture and CBD brands rely on black aluminum caps for a clean, tamper-resistant look. Hot sauce and specialty food producers pair them with Boston round bottles for sauces, oils, and vinegars. Candle makers use them when they need to seal pre-scented oil blends before pouring. And supplement and wellness brands pair our caps with packer bottles to close out their capsule lines. Whatever you're making, if it goes in a glass bottle, it needs the right lid.
Why Buy Glass Bottle Caps from The Bottle Depot
Buying lids and bottles from the same supplier matters more than it sounds. Neck finish mismatches are one of the most common — and most frustrating — issues in small-batch production. When you source both from us, compatibility isn't a guessing game. Our caps are stocked to match the bottles we sell, not random third-party dimensions. Orders ship within 3–5 business days anywhere in the USA, and every order is covered by our satisfaction guarantee. We've served 5,000+ customers since 2018, and lids are one of our most reordered items — which tells you they fit the way they're supposed to.

Frequently Asked Questions
What types of glass bottle lids do you carry?
We carry two main closure types: polypropylene (PP) caps in black and white, and aluminum caps in black and silver. Both are continuous-thread screw caps designed to fit standard glass bottle neck finishes. PP caps are lightweight and cost-effective; aluminum caps offer a more premium look and feel for retail-facing products.
How do I know which lid fits my bottle?
Glass bottle caps are sized by neck finish — a two-part number like 24-400, where the first number is the diameter in millimeters and the second describes the thread count. Each product page on our site lists compatible closure sizes for that bottle. If you're ever unsure, order a sample first to test fit before placing a bulk order.
Are the lids sold with the bottles or separately?
Lids are sold separately on this collection page, which gives you full flexibility to choose the closure style that fits your product and brand. If you'd prefer bottles and caps bundled together, check out our capped bottles collection, which sells glass bottles with lids pre-matched.
Are these caps food-safe?
Our PP caps are made from food-grade polypropylene and are suitable for most food and beverage applications. As always, verify compatibility for your specific formulation and any regulatory requirements that apply to your product category — particularly for products subject to FDA labeling or child-resistant closure rules.
What size range do these lids cover?
Our glass bottle lids are available to fit bottles from 10ml up to 500ml. The size filter on this page lets you narrow by bottle size (oz or ml) so you can find compatible caps quickly. Black, white, and silver options aren't available at every size, so use the color filter to see what's in stock for your size range.
How fast do orders ship, and what's the minimum order?
Orders ship within 3–5 business days to anywhere in the USA. We don't require high minimum orders — our caps are available in case quantities suited to small-batch producers and high-volume brands alike. All orders are backed by our satisfaction guarantee.
