5 Uline Glass Jars With Lids: Sizes, Styles & Bulk Picks
Glass jars are the backbone of every hand-poured candle we make at Small Flame Candle Company. We've tested dozens of containers over the years, and a reliable jar can make or break your final product, whether you're pouring soy wax, storing dry goods, or packaging homemade jams. That's exactly why Uline glass jars with lids keep showing up in our supply orders and in conversations across the candle-making and small business community.
Uline carries a wide catalog of glass containers, which is great, but it also means you can spend a long time clicking through pages before you find what actually fits your project. Different mouth widths, closure types, and case quantities all factor into the decision, and not every jar works for every purpose. We wanted to save you that legwork by pulling together five solid picks worth your attention.
Below, we break down five Uline glass jars with lids by size, style, and bulk pricing. Each one is a container we've either used ourselves or evaluated closely for our production line. If you're shopping for jars that look good, seal well, and ship in bulk, this list will get you moving in the right direction.
1. Uline clear straight-sided glass jars with lids
Clear straight-sided jars are the most versatile option in Uline's glass catalog. The vertical walls make labeling straightforward, and the transparent body lets buyers see exactly what's inside, which matters for retail-ready products like candles, spice blends, or body scrubs.
What you get and why this jar style works
The straight-sided profile gives you a consistent diameter from rim to base, so your label lays flat and looks clean across every unit. This style also stacks reliably during shipping and warehouse storage. For candle makers specifically, the straight walls help wax cool more evenly, which reduces sink holes that curved containers tend to cause.
Lid options and what each one seals well
Uline typically pairs these jars with metal continuous thread (CT) lids or plastic lined caps. Metal lids deliver a tighter seal for products that need to stay airtight, like food items or dried botanicals. Plastic caps work well for candles or cosmetics where you want easy re-entry after the first opening.
If you're selling through retail channels, a metal lid with a printed top tends to look more finished and premium than a bare plastic cap.
Common sizes, case quantities, and best bulk picks
Straight-sided jars at Uline commonly run from 2 oz up to 16 oz, with case quantities ranging from 12 to 144 units depending on size. The 8 oz option tends to offer the best cost-per-unit balance for small-batch producers who want to order enough without overcommitting on storage space.
| Size | Typical Case Qty | Best Use |
|---|---|---|
| 2 oz | 144 | Samples, salves |
| 8 oz | 24-48 | Candles, spices |
| 16 oz | 12 | Bulk goods |
What to verify before ordering
Always confirm the lid diameter listed on the product page before placing a case order. Uline updates their catalog periodically, and a small spec change between restocks can leave you with jars that don't fit your existing closures.
2. Uline clear wide-mouth glass jars with lids
Wide-mouth jars open the entire top of the container, giving you full access to the interior without navigating a narrow neck. That single design difference changes what you can fill, pack, and pour into these containers compared to straight-sided options.
When wide-mouth beats straight-sided
The wide opening makes filling thick products much easier. Solid wax, chunky preserves, or textured body butters go in without fighting the jar. Your spatula or ladle fits cleanly, which speeds up production and reduces mess on the rim.
Wide-mouth jars also make it easier for end customers to scoop out the last bit of product, which matters for repeat purchase satisfaction.
Lid options and what to use them for
Uline pairs these jars with continuous thread metal lids or plastic dome caps. Metal lids work well for food products requiring a proper seal, while dome caps suit cosmetics and candles where appearance and reuse matter more than hermetic closure.
Common sizes, case quantities, and best bulk picks
Wide-mouth jars at Uline typically run from 4 oz to 32 oz, with case counts between 12 and 48 units. The 16 oz size hits the best balance of volume and shelf presence for retail candle products.
What to verify before ordering
Confirm the thread count and lid diameter match your existing closures before placing a bulk order through any uline glass jars with lids listing, since wide-mouth specs vary by manufacturer batch.
3. Uline standard glass canning jars with lids
Standard canning jars are a time-tested format designed to handle heat and pressure without cracking. If you need food-safe containers for preserves, pickles, or pantry staples, this style is worth a close look in the Uline catalog.
What makes a jar "canning" grade for home use
Canning jars are made from thicker, tempered glass that can withstand the thermal shock of hot-water bath processing. The standardized mouth diameter ensures a consistent, reliable seal every time you process a batch.
Lid and band setup, sealing basics, and limitations
These jars use a two-part closure system: a flat lid with a sealing compound and a separate metal band that holds it in place during processing. The flat lid is single-use only for safe food preservation, though the bands are fully reusable.
Never reuse flat canning lids for heat-processed food products, since the sealing compound compresses on first use and will not form a reliable seal again.
Common sizes, case quantities, and best bulk picks
| Size | Typical Case Qty | Best Use |
|---|---|---|
| 8 oz | 12-24 | Jams, jellies |
| 16 oz | 12 | Pickles, sauces |
| 32 oz | 12 | Large batches |
What to verify before ordering
When browsing uline glass jars with lids in the canning category, confirm the jar is rated for your processing method, whether hot-water bath or pressure canning, since not all glass tolerates the same heat levels.
4. Uline French square glass jars with lids
French square jars have a distinctive boxy silhouette that sets them apart from round containers on any retail shelf. If you sell a product where presentation drives purchase decisions, this profile gives you a real visual edge over standard cylindrical options.
Why brands pick the square profile
The four flat sides create more usable label space than a curved jar of equivalent volume, which means your branding reads clearly from a wider viewing angle. Square jars also pack more efficiently in shipping boxes, reducing wasted space and cutting your per-unit freight cost.
Lid options and product types that fit best
French square jars pair well with continuous thread metal caps, which deliver a clean, finished look for retail products like serums, tinctures, or specialty salts. Plastic caps also work for any non-food product where re-sealability matters more than an airtight closure.
The flat-sided profile makes French square jars a strong pick for any product line where shelf differentiation drives repeat purchases.
Common sizes, case quantities, and best bulk picks
These jars typically run from 2 oz to 8 oz through Uline's catalog, with case quantities between 24 and 72 units depending on the size you select.
What to verify before ordering
When browsing uline glass jars with lids in the French square category, confirm the thread diameter matches your cap supplier before committing to a full case order.
5. Uline amber straight-sided glass jars with lids
Amber glass does one thing clear glass cannot: it blocks UV light that degrades sensitive products over time. If you work with fragrance oils, essential oils, or botanical extracts, the amber straight-sided option from Uline is worth a close look before you default to clear containers.
When amber glass matters
UV exposure breaks down volatile compounds in fragrance blends and plant-based formulations faster than most producers expect. Amber glass filters the specific wavelengths responsible for that degradation, so your product reaches the customer in better condition than it would inside clear packaging.
This is a functional choice, not just an aesthetic one, and it can meaningfully extend shelf life for light-sensitive products.
Lid options and compatibility notes
Amber straight-sided jars typically accept continuous thread metal caps or plastic lined closures, the same lid families that fit Uline's clear straight-sided line. Confirm your lid diameter matches the jar thread before placing a full case order.
Common sizes, case quantities, and best bulk picks
These jars commonly run from 2 oz to 16 oz through Uline, with case quantities varying by size as shown below.
| Size | Typical Case Qty | Best Use |
|---|---|---|
| 2 oz | 48 | Samples, serums |
| 8 oz | 24-48 | Candles, blends |
| 16 oz | 12-24 | Bulk formulations |
What to verify before ordering
When comparing uline glass jars with lids in amber, check the UV protection specification in the product listing, since protection levels vary by manufacturer batch.
Next steps
Every jar style covered here solves a specific problem. Straight-sided and wide-mouth clear jars work best when visibility and easy filling drive your decision. French square jars give you a better shelf profile and more label space. Amber glass protects your formulation. Canning jars handle food-safe heat processing. Before you place a case order for any uline glass jars with lids, confirm the lid diameter, thread spec, and case quantity against your production volume so you do not end up with mismatched closures or excess inventory.
Choosing the right container is only half the equation. What goes inside the jar matters just as much.
