If you're new to plastics or are contemplating making your first order of customized plastic jars, here are a five things to consider first:
1. THE LOOK
Aesthetically speaking, what type of jar are you looking for?
Are you searching for the clear, sleek appearance of a styrene jar? Or the smokey, opaque look of a clarified polypropylene? Does the non-transparent, classic white jar suit your needs? Or would you prefer to customize the color? Parkway Plastics allow customers to choose from a palette of nearly 200 colors.
More specialized options, like Frostique Jars, offer a textured, eye-catching alternative if you're looking for a truly customized plastic order.
2. THE WIDTH
ROUND BOTTOM (LEFT); TAPERED THICK WALL (RIGHT)
What diameter suits your needs? Jars range from the narrow, 33mm, to wide-mouth size, as large as 120mm.
For a more distinct or sharp looking plastic container, styles like the Round Bottom or Tapered Thick Walls are options worth considering.
3. THE VOLUME
VOLUME
Essentially, how tall a container are you looking for? Container volumes range from 1/8 oz to 40 oz. The tiny containers are popular in the makeup, cosmetic and skincare industry and are used for products such as lip balms and eye serums. Larger containers work well for shipping small parts, storing foods like peanut butter, nuts and seeds; and are also used in the garden with soil and planting seedlings.
PLASTIC AND YOUR
GARDEN: SIZING
For most gardening needs, whether you're planning to use a plastic jar as a planter or are hoping to store soil or plant trimmings, Parkway Plastic's larger containers elevate your gardening game. These containers have diameters ranging anywhere from 89mm to 122mm; in volume, that translates to containers capable of holding between 16oz to 40oz.
For a fresh and aesthetic DIY look, plastic jars make a durable alternative to glassware. Styrene jars are perfect for making a non-glass terrarium with your kids or creating sleek-looking planters that showcase more than just what's growing above the soil.
If you're looking for a better way to store unused seeds, Parkway carries a selection of smaller containers (recommended diameter, 33mm, and a volume somewhere between 1/4 oz and 1 oz). Also available in a clear styrene, these smaller jars offer a storage option that allows you or the gardener in your life to easily keep track of their seed supply, season after season.
TIP: It's not uncommon for people who order Parkway's smaller plastic jars to find additional applications for them around the house, be it revamping a spice rack, customizing the pantry or decluttering a desk or home office.
4. THE LID TYPE
Do you need Child Resistant Caps? Or would you prefer caps that are more stylized? Options like ribbed, smooth or domed are available at Parkway and offer additional customization.
Other customers, most concerned with finding a tight seal, may opt for a Snap Lock Lid.
5. CAP LINERS
Do your jars need a liner? Or maybe you're wondering 'what, exactly, is a cap liner anyway?'
The functions and types of cap liners vary, ranging from heat sealed liners that prevent leakage to pressure sensitive liners that offer tamper prevention and monitoring.
Foam liners, although not leak-proof, provide a multi-purpose sealing option that enhances shelf life and allows subsequent sealing after the container is opened. Popular with personal care are cosmetic disc liners, which are mostly aesthetic but do provide a barrier of sorts between the product stored and foreign bodies with which it could come into contact.
Now that you know the five basic steps to deciding which type of liner your product needs, click here to GET STARTED! If you're still hesitant or unsure, we're here to help! Feel free to CONTACT US!

A product's packaging is just as important as the product itself. You want to ensure that whatever you are packaging has the right container and lid. Determining the ideal packaging method requires many considerations, including the container size and dimensions.
In this guide, we'll be exploring the type of container with a larger opening, commonly identified as a jar or canister. We'll walk you through what a jar and canister thread size and dimensions mean. This should help to understand packaging options and select the best wide-mouth packaging for your product needs.
A thread size is another term for a neck finish, or the protrusion of the container that a lid or closure is fastened to. Typically, for wider-mouthed containers, the term 'thread size' is used instead of 'neck', which is often used for bottles and containers that feature a narrower opening at the top.
Each thread has a two-number identification system to differentiate the size of the thread. The first two-digit number refers to the neck width or the width of the opening of the container. The second three-digit number refers to the finish of the thread, which is the seal of the container.
The dimension of a jar and canister refers to the size of the container itself. It measures the width, length, and area of the container so that you can determine how much product will fit in the jar. For example, when looking at mason jar sizes, what you are really measuring is mason jar dimensions, so you know how many ounces can fit into the container.
The thread size and dimension you choose has a major impact on the success of your product packaging. You can mix and match threads to dimensions, but they are often related.
Selecting the appropriate thread size is an essential aspect of your packaging selection, as it aligns with the product's purpose and helps provide a smooth packaging experience for the customer. By carefully considering the product's purpose and opting for the most suitable packaging to fulfill that purpose, you can offer your customers an optimal product experience from the start.
Here are a few of the most common canister and jar thread sizes and finishes that you will encounter when looking at different packaging options. Each variety has a different purpose and is used for various industries and types of products.
A thread finish found on small plastic jars ranging from ¼ oz to 1 oz sizes. These small jars are mainly used for creams and balms. Continuous thread 33-400 plastic caps are most commonly used with this thread finish.
Another common thread finish found on small plastic jars but accommodating slightly larger jar sizes ranging from ½ oz to 2 oz. Continuous thread 48-400 plastic caps are most commonly available for this thread finish.
A thread finish found on plastic and glass jars. Straight-sided jars are the most common style available in 1 oz or 2 oz sizes. Continuous thread 53-400 plastic or metal caps work best with this thread finish.
A thread finish found on plastic and glass jars. 4 oz straight-sided jars are the most common style with this thread finish, but a 58-400 thread finish can also be found on 8oz paragon jars. 4 oz is a common size jar for creams, lotions, and powder products. Continuous thread 58-400 plastic or metal caps work best with this thread finish.
A thread finish found on glass jars such as mayo economy and hex jars. It can also be identified as 58 lug finish. The lug finish allows an air-tight seal which creates a popping noise when the seal is broken. A 58-lug metal cap works best with this thread finish and is commonly used to store food products such as salsa, preserved foods, jams, honey, and more.
A thread finish found on glass jars such as paragon, sauce, universal, and hex jars. It can also be identified as 63 lug finish. The lug finish also allows an air-tight seal which creates a popping noise when the seal is broken. A 63-lug metal cap works best with this thread finish and is commonly used to store food products.
The largest common lug size found on glass jars such as mayo economy and universal jars ranging from 12 oz to 32 oz. It can also be identified as 70 lug finish which provides the same air-tight seal as other sizes.
A common thread finish found on plastic and glass jars. This thread is more commonly found on plastic containers including single-wall jars, thick-wall jars, double-wall jars, straight-sided jars, and straight-sided canisters. Common sizes with this thread finish range from 2 oz to 8oz for jars and 16oz for straight-sided canisters. Continuous thread 70-400 plastic or metal caps work well with this thread finish, but plastic is the more common option.
A thread finish only found on glass jars, most commonly on mason economy mayo jars ranging from 8oz to 32oz. This thread and jar type works well for food products. Continuous thread 70-450G metal caps work best with this thread finish.
The most versatile thread finish for wide-mouth containers. 89-400 thread finish is found on glass and plastic jars and canisters. More commonly found on plastic containers, the 89-400 thread is used across a variety of sizes ranging from 4 oz to 32 oz. For the lower range of sizes, jars with an 89-400 thread include shapes such as straight-sided jars, square pinch grip jars, single wall jars, double wall jars, and thick wall jars which are options used for creams, lotions, gels, powders, and more. For larger sizes, options are canisters which are often used for powders. Continuous thread 89-400 plastic caps are the most used to pair with an 89-400 thread container.
A common thread finish for larger wide-mouth plastic and glass containers. 110-400 thread finish is found on wide-mouth jars and straight-sided canisters. This thread finish accommodates larger-size containers ranging from 64 oz to 1 gallon. Plastic containers with this neck finish include wide mouth jars, square pinch grip jars, and straight-sided canisters while glass can only be commonly found in the wide mouth shape. Continuous thread 110-400 plastic caps work best with this thread finish and can accommodate accessories such as a scoop to help end users measure and retrieve accurate product quantities.
A common thread finish for larger straight-sided canisters. 120-400 thread is found mainly on canister sizes ranging from 32 oz to 120 oz. These larger canisters are commonly used for powder products which may include a scoop accessory for the end user to accurately measure and use the product. Continuous thread 120-400 plastic caps are the most common option to match this thread finish.
It's also important to consider the common canister and jar dimensions when you look at packaging your products. This will determine how much product fits into each container. Some of the most common dimensions include:
While we often think of typical screw-style lids as the closure device for canisters and jars, there are some other options and variations that you might want to consider. Here is a helpful list of the different closure types that can be used for different jar and canister sizes.
Child-resistant closures are great for pharmaceuticals and other sensitive materials like chemicals. These lids have a locking mechanism that requires pressure in order to open, which makes it difficult for children to open or ingest the contents.
A phenolic with cone closure is commonly used with chemicals, solvents, and alcohols. This type of closure has a thread that spirals uninterrupted on the cap wall with a natural cone in the middle. They are a special type of continuous thread, but the cone provides additional protection for liquids inside, such as chemicals or oils.
The continuous thread is the most common type of closure. It has a thread that spirals up the side of the cap and can be made of metal or other materials like plastic. They work well for paints, personal care products, pet care products, beverages, food products, and liquids. The metal lid is what we often associate with a mason jar thread size, which can be used for purposes like canning and food storage.
Lug caps can be identified by the distinct popping sound they make when first opened. Unlike continuous thread caps, lug caps have equally spaced threads that are not continuous. These caps are made of metal and are only suitable for use with glass jars that have a lug neck finish. They often incorporate silicone seals. Lug caps are a favored choice for products that require an airtight seal, such as salsas, jams, and other food items.
Although less common with wide-mouth containers, a pump is an option available to keep a product sealed while offering an opening for the product to be distributed in a pump. They can be adjusted to account for the viscosity of the material in the container. They work best for personal care products, such as lotion.
Scoops are an accessory that is commonly used with wide-mouth jars and canisters in the protein powder and supplement industry. They're available in a variety of shapes and sizes.
Now that you have a better understanding of thread sizes and finishes, here are some helpful tips on how to choose the best options for your product packaging needs.
Consider what your industry is and what common thread sizes are used to package products. Think about the customer using your product and what thread size and finish will be the best for their experience. Examine competitors in similar shelf spaces to see the thread size and dimensions that they commonly use in their packaging. Consider which options are best to buy in bulk or wholesale. Work with packaging experts who understand the ins and outs of packaging to help you craft the perfect solution.
Finding the right thread size and dimension for your packing requires you to understand the many factors that go into packaging sizes. Trying to pick the best solution on your own can be overwhelming, especially when you are focused on other areas of your business. That's why working with experts is the best way forward.
