1. Are Jars Sealing?

People seem to be complaining to Google that Jars are not Sealing. Don't put yourself in a situation like that.
If you're one of these people, and you're experiencing that your jars aren't sealing right, then it might be time for you to evaluate your packaging. Knowing that your product will have a good seal will be a comforting relief; especially if you've been through the process before and never really found a solution. Let us help.

So, how are jars Sealed?

There are many ways to seal jars, from vacuum sealing mason jars, to heat induction sealing and pressure sensitive sealing plastic jars. To heat induction seal a jar you will need Heat Seal Liners and a heat induction machine. The heat seal liners can be purchased and delivered to you in 2 different ways: either lined in your caps or by themselves in bulk without caps. You can seal your jars with Parkway's Foam liners, Pressure Sensitive Liners or Heat Induction Liners. Learn more about Parkway's liners here: Liners 101.

What do I do if my Jars are not Sealing?

So your jars aren't sealing? That's a bummer. It's very important that your jars seal; it's essential for your product's survival. A good seal will help prevent your product to leak from production to store aisle, and throughout your customers use. We understand it's frustrating. No-one wants to find out that their Jars are leaking; It's never fun, regardless of where you are in the process of finding out. If your products' packaging isn't compatible, there's only one thing to do: Evaluate the Problem - Sample New Packaging including all Liners - Correct the incompatibility.

Depending on what you aim to do with your sealing and your jars, there are different methods to seal jars. One common sealing method used all over the world among ordinary people is Vacuum Sealing Jars through Canning.

Canning - How Jars are Vacuum Sealed:

If you're canning veggies or food then you canning jars seal in two parts. If Mason Jars, we're referring to the Lid itself, and the ring around it. Yes, you know what I mean. The ring that holds the lid in place during canning and seals the jar in the heating (boiling) process. It seals by the heat. However, If you are canning jars you might have noticed that sometimes there's air left in the jar. One purpose of the boiling process is to drive the air out from the jar, and it usually works. The next step of the sealing process in canning is the vacuum seal that happens when the jar cools and the air is removed. That's how we get the Pop & we all like to pop open jars, don't we?

Speaking of Jars that pop, did you know that you can get your Jars to POP with Parkway's Custom Colors?

2. Are Jars Oven Safe?

Not all Jars are Oven-Safe. Oven Safe Jars would refer to Jars that won't be affected by the high temperatures in the oven. Jars would maybe be considered oven-safe if the material of the jar can't be affected or compromised by the heat of the oven. We always recommend looking over spec sheets if you are wondering what temperatures your particular jar can stand up against. Regardless of the jar: Plastic Jars or Glass jars (such as Mason Jars), always do your own research before testing anything in the oven. Some websites says Mason Jars are completely fine to Bake in, others say Do Not put Mason Jars in the Oven. Unfortunately, I can not tell you what's safe and what's not safe when it comes to Mason Jars. But what would you bake in a Jar?

Chocolate Cake in a jar:

1 stick plus 3 Tbsp. Butter or Margarine
3 cups White Sugar
4 Eggs
1 Tbsp. Vanilla
2 cups Applesauce, unsweetened
3 cups White Flour
3/4 cup unsweetened Cocoa powder
1 tsp. Baking Soda
1/2 tsp. Baking Powder
1/8 tsp. Salt

3. Are Jars Smell Proof?

Some jars are smell-proof and other jars are not smell proof. What makes a jar Smell Proof and Odor Proof are a few different components such as the Jar itself, the cap, closure, liner and seal of the jar. You need to sample jars, caps and liners to ensure product compatibility. Think of airtight containers such as vitamins bottles or jars. That's the kind of seal you probably want if you are looking for a smell-proof jar. A child resistant closure might help you along the way towards good smell proof packaging, especially if you're trying keep the jar out of reach from children. Parkway's plastic Jars, Containers and Packaging may be Smell Proof when matched with the right liner and accessories. However, it is always recommended that you test Smell Proof Jars with your product to make sure that the Jars are Smell Proof and airtight with your product. Smell Proof Containers is a very common request across various industries today, especially in the growing market for Medical Marijuana. The need for Smell Proof Containers and Smell Proof Jars have increased with a growing market.

4. Are Jars of Baby Food OK?

So you're a Parent and you purchased food for your baby in a Jar. You come home and you start questioning yourself: Are Jars of baby food really healthy? "Maybe it's just better I make my own solid foods for my baby..."

We understand your concern. There are a few things you should know when it comes to jars and baby food:

If the baby food is in a plastic jar, make sure the plastic jar is FDA approved. You can also check if the plastic jar is BPA Free. Those are two good things to research. A quick thing that you can check is the number of the plastic in the bottom on the jar. The number indicates the plastic material used for production and manufacturing of the jar. If the bottom of the jar either say Polypropylene PP (5), LDPE (4), HDPE (2) or PETE (1), it's usually Food Safe (if FDA approved). If the food is in a Glass jar, it's also most likely safe. If you are still wondering if the jar of your baby food is safe, contact the brand of the baby food.

Once you've checked that your plastic jar is good to go, Why not put some healthy snacks like Banana, Avocado, Yogurt or Dry Fruits in the plastic jars. Perfect on-the-go for baby and you! Jar packaging isn't all that bad after all!

5. Are Jars Microwavable Safe?

Can I microwave a mason jar? Are Jars Microwavable? - Common Questions asked by people.

One important aspect of whether it would be OK or NOT OK to microwave jars depends on the material of the jar. Is it a glass jar? is it a plastic jar? If so, is the jar BPA free? BPA: Bisphenol - A, is an endocrine disrupter, a substance that mimic hormones of humans. Needless to say, It is not good, which is why we at Parkway Plastics only manufacture BPA- FREE Plastic Jars. Another substance that you should stay away from as well when it comes to Plastics, (and especially if you intend to microwave) is the substance called Phthalates. This substance is many times added to the plastic to make it soft and flexible. It is however not good for you. Which again, is why Parkway Plastics only manufactures Phthalates- free plastic jars.

Some would say that Polypropylene PP material (recycle code 5) is OK to microwave due to the higher temperatures the material can withstand. However, always do your own testing as check spec sheets.

7. Are Jars for Labels?

Records labels? No. Labels for Jars, Yes! Parkway Plastics manufactures plastic jars like seen on the picture below, in many different styles and versions. Parkway offers decorating & labeling services that can be part of your packaging process with Parkway.

Parkway Plastics offers Decorating and Labeling:

Labels

Labels: "The labels that our jars accept are called "Smilex" labels because they are shaped like an upside down smile. Our jars require the use of this particular wrap label because our jars have a slight taper to them that make labeling them a little bit more tricky. Labeling is a great decorating method though because it is reasonably inexpensive and can be as detail oriented and have as many colors as you like." Learn more here: Labels
