A useful type of food storage container, mason jars are versatile, practical, and incredibly efficient. You can store just about anything in a mason jar, making them some of the most multipurpose storage options on the market. However, a mason jar is only as reliable as its lid.
With such a wide range of lids on the market these days, it can be a bit tricky to know which lids are worth purchasing. But don’t worry! We put this comprehensive guide together to help you navigate the world of mason jar lids. Let’s explore the factors we think you should consider before buying a new mason jar lid.
Material
Mason jar lids are most commonly made of metal or plastic. Metal lids are usually made out of tin, stainless steel, or aluminum. Not only are they highly durable but they are also perfect for canning purposes. They’re often coated with the goal of resisting rust, and they are also dishwasher-safe.
On the other hand, plastic mason jar lids are more suitable for storing dry goods or craft-related tools. They’re typically BPA-free, and they tend to be less prone to denting or rusting than other options. When choosing which mason jar lids you should buy, pick the lid type that is more ideal for your intended purposes.
Size
When it comes to purchasing mason jar lids, size matters. The most common sizes are regular-mouth lids with diameters of 2.75 inches and wide-mouth lids with diameters of 3.38 inches. Regular-mouth lids are suitable for small jars, and that's why they are most commonly used for canning smaller fruits or vegetables.
Alternatively, wide-mouth lids are specifically made for large jars, making them ideal when you're pickling foods or storing larger items. Always ensure that you measure the opening of your jar before buying a lid.
Type
Mason jar lids are available in two main types, including two-piece lids and single-piece lids. Two-piece lids are perfect for canning purposes because they create a vacuum seal, which is necessary for the preservation of food. However, single-piece lids are more convenient for storing everyday items or serving foods shortly after preparing them. Just make sure you opt for the type of lid that caters to your intended uses.
Design
Design is a vital factor to consider when shopping for mason jar lids because the design of the lids will affect both functionality and aesthetics. This ensures that the lid fits securely while simultaneously enhancing the overall look of the jar. Mason jar lids are available in various styles and designs, including classic metal screw-on lids and reusable flip cap lids as well as customized options for specific functions, like pouring, storing, or crafting.
Seal Quality
Seal quality is crucial when purchasing mason jar lids. This is what determines how well the mason jar lids preserve the freshness and flavor of the jar’s content. If canning is your intended use, look for lids with a sealing compound around the inner edges to ensure a reliable vacuum-sealed effect. Now, for storage or decorative purposes, simple lids that don't have a sealing compound are suitable. Plus, they are more cost-effective!
Durability
Durability is another factor to consider when purchasing mason jar lids specifically for safe and secure storage. Metal lids with a rust-resistant coating are durable. They can also withstand high temperatures during the canning process. Now, although plastic lids are not suitable for canning, they are perfect for keeping goods dry or storing arts and crafts supplies because they are dent- and rust-resistant.
Price
Last but not least, consider the price of mason jar lids before you purchase any. While mason jar lids are generally affordable, the costs can add up if you’re buying them in bulk. Keep in mind that metal lids are usually more expensive than plastic ones due to their durability and canning suitability. Always consider your budget and the number of lids you’ll need before submitting an order.
