Packaging is not just about aesthetics; it is also crucial in protecting and keeping products in top condition. One of the most popular types of packaging is plastic jars — they are durable, lightweight, and affordable. However, with so many options available, choosing the right plastic jar for your product can be daunting.

This article will guide you through selecting the perfect plastic jar for your product packaging. Here are the three steps in finding the right plastic jar for your next project:

Step 1: Understand Your Product

To choose the right plastic jar for your product packaging, it is crucial to understand your product and its specific requirements. This means considering various factors that will influence your choice of packaging, such as the following:

Product Type

The packaging requirements will vary depending on whether the product is liquid, solid, or semi-solid. For instance, a liquid product will require a jar with a tight-fitting lid and a narrow mouth to prevent spills. On the other hand, a solid product may need a wider mouth for easy access.

Product Quantity

The product quantity will help you determine the appropriate size of the plastic jar you need. Choosing a jar that is too small may result in an insufficient amount. However, selecting a too-large jar will result in wasted space and potential product damage.

Product Shelf Life

Determine your product’s shelf life and whether it requires special protection from sunlight or moisture. These factors will help you choose the most suitable plastic jar material and design to keep your product intact.

Step 2: Choose the Right Material

Once you understand your product’s requirements, you must choose the right material for your plastic jar. The most common materials used for plastic jars include the following:


LDPE is a thermoplastic polymer that is produced from ethylene monomers through polymerization. LDPE has a relatively low melting point and is known for its excellent flexibility, toughness, and transparency.


Polyethylene terephthalate (PET) is a lightweight, clear plastic commonly used for packaging food and beverages. It is shatterproof and has good barrier properties, making it an excellent choice for products that require protection from oxygen and moisture.


High-density polyethylene (HDPE) is a tough, opaque plastic commonly used for packaging detergents, household cleaners, and personal care products. It is resistant to chemicals and has good impact resistance, making it a popular choice for products that require durability.


Polypropylene (PP) is a tough, flexible plastic commonly used for packaging food, cosmetics, and pharmaceuticals. It has good heat resistance and is microwave safe, making it an excellent choice for reheating products.

Other Materials

Other materials — such as polystyrene, PVC, or bioplastics — may be suitable for specific products or applications. Consult with your packaging supplier to determine the most appropriate material.

Step 3: Select the Right Shape and Size

The shape and size of the jar can affect the product’s functionality, aesthetic appeal, and brand identity. Here are some factors to consider:


Consider the aesthetic requirements of your product, such as transparency, color, texture, and finish, when selecting the shape and size of your jar. Ensure that the chosen jar complements your product’s appearance and function. Take into account existing color schemes or branding, and choose a size that fits your product quantity and packaging needs.


Your plastic jar should reflect your brand’s identity and values. Consider the shape and size that will best represent your brand. For example, consider a sleek and elegant jar with a minimalist design if you have a luxury skincare line.

Storage Space

If your product is displayed on shelves, choose a shape and size that is easy to stack. This will help optimize shelf space and make your product more visible to customers.


Consider the labeling requirements of your product, and make sure the shape and size of the plastic jar allow for easy branding. For instance, a flat or smooth surface will ensure the label adheres well to the jar and is legible to customers.

Ergonomics refers to the product packaging’s ease of use and comfort for the end-user. For example, the shape and size of the jar should be portable or handy to make it easy for customers to carry.

Material Thickness

The thicker the material, the more durable the jar and the less likely it will break or crack. However, thicker materials may also add to the cost of the packaging, so consider balancing durability with your budget.
