Is there BPA in mason jar lids?
For several years, home canners were concerned, rightly or wrongly, about the presence of the compound in the lining on the underside of their canning lids. In response to consumer demands, major mason jar lid manufacturers in North America removed BPA from their lids.
Despite its seemingly limitless abilities, however, the Mason jar does have some downsides, as pointed out by Life Without Plastic in a recent newsletter. First, you know that white undercoating on the lids? It contains a chemical called bisphenol A (BPA), or, where advertised as BPA-free, a substitute called BPS.
The bottom of the lid has an enamel coating and a channel filled with a sealing compound. During the canning process, the sealing compound softens allowing air to escape while covering the jar-sealing surface. Upon cooling, the compound hardens forming an airtight seal.
But did you know that many Mason jars come with lids that rust and that have a plastic lining on the interior that often contains bisphenol A...
Mason jar lids are made of tinplate, which is not easy to rust, and is resistant to high and low temperatures, and can be used many times, the lid has a silicone ring, good sealing performance.
A little rust on the outside of your rings isn't a bad thing. However, you do want to stay away from the rings that become distorted or have rust on the inside or any part that will be in contact with your lid or the jar.
Ball jars have long been approved for pressure canning.
The metal 2 piece lids that accompany these jars are also approved for pressure canning for home canners by the National Center for Home Food Preservation.
You can reuse glass canning jars, but don't be tempted to reuse canning lids, she advises. The gasket compound in used lids may fail to seal on jars, resulting in unsafe food. When jars are processed, the gasket on new lids softens and flows slightly to cover the jar-sealing surface.
If you have canning lids that you've already used, is it safe to reuse them again? The simple answer is no: Canning lids are designed for one-time use. Using them more than once may result in your jars not sealing properly. These lids have a special sealing compound around the rim that is only good for one use.
Cleaning the lids
Before using them, wash the lids by hand without dish soap in hot water. The lids are not dishwasher safe and must not be boiled before first use. It is important to know that the glass jars can be reused, while the lids must be changed for each new use in order to guarantee their hermetic seal.
What type of plastic is jar lids made of?
The plastic caps are usually made of Polyethylene Terephthalate, Polypropylene, Low-Density Polyethylene, High-Density Polyethylene, Polyvinyl Chloride, Polystyrene and Polycarbonate. Polyethylene Terephthalate (PET) is non-toxic, light in weight, strong and durable, environmentally friendly and recyclable.
Our jars are Made in America and are annealed glass which is lead-free and food safe. They are made from lime, soda, cullet and silica. Our lids are BPA free and made of tin plated steel with a red ring plastisol sealant.
COLORED JARS
Blue, green and purple jars have been made for home food preservation. However, there are other colored jars, such as yellow, available for craft projects, but are not recommended for food preservation.
Between 1860 and 1900, many other patents were issued for Mason jar improvements and closures. In 1903 Alexander Kerr introduced lids with a permanent rubber seal. His improved design in 1915 used the modern design. Jars are closed with two-piece metal lids that seal on the rim.
What jars/lids do you recommend? We can only recommend the jars that have the 2 piece lids, like Ball, Kerr, or Leifheit to name the major brands. They are the only type of jars recommended by the USDA. No other jars or lids (including the Tattler lids) are approved by the USDA for canning in the US.
Gaskets in unused lids work well for at least 5 years from date of manufacture. The gasket compound in older unused lids may fail to seal on jars. Buy only the quantity of lids you will use in a year. To ensure a good seal, carefully follow the manufacturer's directions in preparing lids for use.
Boiling newer lids may destroy the sealing compound and lead to seal failure. Warming the sealing compound before you apply the lids will not harm the lids and may help jars to seal.
Tap the lid with the bottom of a teaspoon. If it makes a dull sound, the lid is not sealed. If food is in contact with the underside of the lid, it will also cause a dull sound. If the jar is sealed correctly, it will make a ringing, high-pitched sound.
Can I pour boiling water into a Mason jar? Yes, you can pour boiling water into your Mason jars, and you can also insert them into a pan full of boiling water for sterilization. However, make sure your Mason jars are at least room temperature before placing them into the water.
Storing fresh fruit and vegetables in mason jars is a great way to extend their shelf-life. With the proper preparation, some produce can last up to twice as long as fruit kept in plastic containers.
Why do Mason jar lids come in two pieces?
In home-canning a two-piece lid is needed to let the air escape during the boiling water or pressure canning process. A one-piece lid doesn't allow the air to escape resulting in blowing out the bottom of the jar or the lid to buckle. Driessen, Suzanne. Food Preservation FAQs.
Before beginning any canning recipe, prepare jars and lids as directed by the manufacturer. Ball recommends the following: “it is no longer necessary to pre-warm lids before use. If you desire, it is still safe to simmer your lids before use, however, you should never boil them.
They are intended for one use only. There will be greater seal failures and jar breakage because the glass is not well-tempered.
Article content. Answer: If you're planning on canning, you can reuse your purpose-made glass jars and screw bands, as long as they're in good condition.
Ball extends shelf-life recommendation from 12 to 18 months
When using the new SureTight lids & following a tested/approved recipe for safe home food preservation, the new shelf life will be up to 18 months.”
One-piece, reusable, and previous used lids are not approved for home canning by the USDA as they may allow air to be trapped within the sealed jar permitting bacteria to thrive and spoilage to occur which can lead to illness and even death.
Place new lids (you must use new lids each time you do canning; bands can be reused if in good condition) in a small saucepan, cover with water and bring to a simmer (180°F). Lids must be simmered for 10 minutes to "activate" the sealing compound that helps achieve a vacuum seal.
A dishwasher is a good way to sterilize mason jars, as the rubber ring seals aren't suitable for many other methods. Don't put anything else in the dishwasher, aside from your jars, lids and rubber rings you want to sterilize.
When cooking or oven-canning with Mason jars, especially with the lid on, the heat and steam can put explosive pressure on the glass, leading to, at best, an impossibly messy kitchen, and at worst, serious burns, cuts, and shards in your food and skin.
It's important to avoid plastic coffee lids as well as plastic soda and fruit juice bottles. The heat and acidity of the liquid cause high levels of BPA to leach into your drink.
Are polypropylene lids safe?
Plastics #5 Polypropylene (PP) is considered to be the safest of all plastics, this is a robust plastic that is heat resistant. Because of its high heat tolerance, Polypropylene is unlikely to leach even when exposed to warm or hot water. This plastic is approved for use with food and beverage storage.
The plastic caps, as convenient as they may seem, aren't safe for use when canning your own food at home. These lids are meant to be used for storage only and can have downsides, such as leaking or producing mold, since they are less air-tight, as noted in Healthy Canning.
Glass storage is not only a more sustainable option but is also a much safer alternative for all the family. Glass does not contain BPA so will keep your food free from unwanted chemicals.
Ball, Bernardin and Kerr are all owned by Jarden Home Brands and are all manufactured in the USA.
Nothing is cooler than a blue Ball® glass jar, right? Those blue mason jars were mass produced until 1937 using sand from around Lake Michigan. It was that sand that gave the glass its blue hue.
Blue glass Ball jars were produced in the late 1890s and early 1900s, but the company stopped producing these in 1937. There were also some brown amber jars produced in the 1950s, but most of the jars produced after the 1940s were made of clear glass.
Even when you purchase new jars in a box covered in plastic wrap, those jars are still not in a sterile environment. In addition to contamination by microorganisms that cannot be seen, packaged jars may accumulate dust, small bits of debris and even chips of glass in the case of breakage.
Do I need to pre-sterilize my jars for canning? New canning jars out of the box are not sterile. Being in a box or covered in plastic wrap is not the same as a sterile environment.
Before we dig into the jars, you should know that all standard canning jars sold in the U.S. are made by a company called Jarden Home Brands. They own Ball, Kerr and Bernardin (that's their Canadian brand). So though it appears that there are multiple brands of jars out there, they're all made by the same manufacturer.
Vintage Glass Color
Like other types of antique and vintage glass, color can indicate the year of production. Most vintage Mason Jar glass was made in deeper aqua blue or “Ball Blue”. The sand used to make the “Ball Blue” color was from the Hoosier Slide sand dune on Lake Michigan.
Do Ball mason jars have BPA?
In response to consumer demands, major mason jar lid manufacturers in North America removed BPA from their lids. To be clear, all Ball and Bernardin branded lids being made as of 2015 and onwards will be BPA free. 2 How do you tell if your Jarden lids are BPA free?
- Asparagus, Spear or Pieces.
- Beans or Peas – Shelled, Dried, All Varieties.
- Beans, Baked.
- Beans, Dry, With Tomato or Molasses.
- Beans, Fresh Lima--Shelled.
- Beans, Snap and Italian – Pieces, Green and Wax.
- Beets – Whole, Cubed, or Sliced.
Failure of lids to seal may be caused by one or more of the following: A chip on the rim of the jar. Failure to follow manufacturer's directions for preparing flats. Presence of food particles on jar rim. Always wipe rim clean before putting on lids.
Bernardin has confirmed that it is discontinuing GEM lids. In a statement from Friday, a spokesperson for the company said it has decided to prioritize increasing production of regular and wide mouth lids to address product shortages driven by the COVID-19 pandemic.
Stuck at home, people picked up gardening, then canning their harvest. "That led to a supply shortage of canning lids," said Suzanne Driessen, University of Minnesota Extension food safety educator. That supply and demand problem, specifically for the two-piece metal lid, simply hasn't gone away.
There are three safe ways of canning, depending on the type of food being canned. These are the boiling water bath method, the atmospheric steam canner method, and the pressure canner method.
Our jars are Made in America and are annealed glass which is lead-free and food safe. They are made from lime, soda, cullet and silica. Our lids are BPA free and made of tin plated steel with a red ring plastisol sealant.

Tap the lid with the bottom of a teaspoon. If it makes a dull sound, the lid is not sealed. If food is in contact with the underside of the lid, it will also cause a dull sound. If the jar is sealed correctly, it will make a ringing, high-pitched sound.
Canning jars have a life expectancy of 10–13 years. After that, you will experience more breakage because of the wear and tear of normal use. Because of this, it is not recommended to use vintage or antique canning jars for food preservation.
Why are mason jar lids like that?
Mason jars are glass jars that have an airtight screw-on lid specifically made for home canning and preserving. These lids have a unique design which includes two parts that help seal the jars shut when subjected to heat through a water bath canner or a pressure canner.
Yes, always wash your canning or candle jars before using them – whether they are bulk canning jars or ones in retail packaging.
It is important NOT to boil the metal canning lids or their rings. The extreme heat of boiling water can harm the rubber sealing rings on the lids, which can result in a broken seal and contamination of the jar's contents.
Sterilizing is a crucial part of preserving to remove any bacteria, yeasts or fungi thus protecting the food you put into the jar. Dirty or jars not correctly cleaned will infect the food inside, and it will spoil very quickly. Sterilizing is a quick and easy process so therefore should never be omitted.
If you have canning lids that you've already used, is it safe to reuse them again? The simple answer is no: Canning lids are designed for one-time use. Using them more than once may result in your jars not sealing properly. These lids have a special sealing compound around the rim that is only good for one use.
Mayonnaise-type jars are not recommended for use with foods to be processed in a pressure canner because of excessive jar breakage. Other commercial jars with mouths that cannot be sealed with two-piece canning lids are not recommended for use in canning any food at home.
Grocery store jars that once held spaghetti sauce, pickles and other foods should not be reused for home canning. The glass is usually not as thick and this makes them more likely to shatter or explode when heated.
