Thick Wall, Double Wall or Regular Wall Plastic Jar?

Which Straight Sided Plastic Jar is Best for Your Product?

You’ve perfected your product formulation and are ready to take it to market. You’ve decided to package your product in a plastic straight sided wide mouth jar. But which one is best for your product? To help you decide, here is a comparison between the different types available here.

From the outside, these plastic straight sided thick wall, double wall and regular wall jars don’t appear very different. However, a visual comparison of the inside of each jar may provide some insight:

Thick Wall Jars

Thick wall straight sided jars are the heaviest and most durable of the three. These jars are constructed from a single piece of plastic. The thicker wall construction provides extra protection through packaging and shipping, and creates a smooth and flush surface from the closure to the container. As the most expensive option, the thick wall’s aesthetic is meant to resemble glass and give your product a high-end shelf presence.

Construction

Commonly made of polypropylene (PP) or polystyrene (PS) plastic
Molded from a single piece of plastic for extra durability
Single-mold design ensures that these jars will not come apart during filling, shipping, packaging, assembly or printing
Less expensive than glass to produce and ship
Thicker wall construction provides added protection
Offers good chemical resistance

Design

Heavier and more durable than double wall or regular jars
Made to resemble the high-end look and feel of glass
Offers a clean, contemporary look
Allows the side of the closure to run flush and even with the sides of the jar

Possible Applications:

Nail powders, acrylic powders, skin creams, glitter, eye shadow, hair treatments, pomades, waxes and more

Double Wall Jars

To obtain the elegant, high-end look of glass or a thick wall jar at a lower price, double wall straight sided jars are a solid choice. Double wall jars are constructed from two separate pieces of plastic that are mechanically molded together to create a straight-sided container that is virtually a “jar within a jar.” This type of jar requires less material to produce but offers the look of a larger size of container for a more aesthetically pleasing shelf appearance. Also, the second “wall” also provides more protection and durability. The most common uses for these jars are lotions, creams and hair products.

Regular Wall Jars

As consumer preferences trend toward more sustainable and environmentally friendly packaging, the light weight and streamlined walls of regular wall straight sided jars (or “single wall”) are in high demand. As less plastic is needed to produce these containers as compared to thick and double wall wide mouth jars, regular wide mouth jars are the least expensive and most economical choice. Regular jars can be used for a wide range of industries including cosmetics, food and beverage, automotive, healthcare and paints.
