Choosing the Right PET Straight Sided Jar for Your Product: Tips and Tricks for Brands

For brands navigating the competitive market landscape, the choice of packaging plays a pivotal role in product perception, user experience, and overall brand identity. PET (polyethylene terephthalate) Straight-Sided Jars (SSJs) offer a versatile and sustainable solution for a wide array of products. However, to truly harness the benefits of these jars, brands must ensure they select the right fit. Here’s our guide guide on making the perfect PET SSJ choice for your product.


1. Understand Your Product’s Needs

Before diving into the selection process, have a clear understanding of your product. Is it a thick body butter or a delicate eye serum? The consistency, texture, and usage of your product will influence the size and type of SSJ you’ll need.

2. Size Matters

PET SSJs come in a spectrum of sizes. For premium, concentrated products, smaller sizes may be more appropriate, while bulk items might require larger containers. Moreover, consider user experience; ensure the jar’s opening is wide enough for easy product access.

3. Clarity vs. Colour

While one of the significant advantages of PET SSJs is their clear, glass-like appearance, they can also be tinted or opaque. If your product’s appearance (like a vibrant scrub or a creamy lotion) can enhance its appeal, opt for clear jars. For products sensitive to light or for a unique aesthetic, consider coloured (amber is perfect!) or frosted SSJs.

4. The Lid is the Limit

Lids aren’t just functional; they’re integral to the packaging design. Think about the type of closure that aligns with your brand and product. For instance, a luxury brand might opt for metallic or wooden lids, while a more eco-centric brand might choose a simple, recyclable plastic lid.

5. Think Recyclability

Showcasing a brand’s commitment to sustainability can be a USP. PET is one of the most recycled plastics. Highlight this aspect in your marketing and consider using post-consumer recycled (PCR) PET SSJs.

6. Customisation for Brand Identity

While standard PET SSJs offer myriad benefits, consider custom designs to make your brand stand out. Whether it’s a unique shape, a logo imprint, or a specialised finish, custom touches can elevate your product’s shelf appeal. At BlueSky, we can support you with your customisation needs.

7. Consider Labelling and Printing

The flat, smooth surfaces of SSJs make them ideal for branding. Consider the type of labels or printing that will adhere best to PET. Ensure that your design complements the jar’s shape and enhances product visibility if you’re using clear SSJs.

8. Test Before You Invest

Test them with your product to ensure compatibility, especially if your product has ingredients that might react with plastic. This step ensures that there are no unexpected surprises post-production.

9. Budget Wisely

While PET SSJs can be cost-effective, added customisations or specific design choices can influence the price. Have a clear budget in mind and we’ll support you the best value with options, without compromising on quality.


PET Straight-Sided Jars offer a harmonious blend of aesthetics, functionality, and recyclability.
