Square PET Jars

Square PET JarsSKS has a wide array of PET plastic square jars, available in clear and blue colors in 4 oz, 8 oz and 16 oz sizes. These square jars have wide openings, allowing for easy application of products such as body butter, face scrubs and lotions. The 4 oz and 8 oz sizes have 70/400 neck finishes, while the 16 oz has a 89/400 finish, each compatible with a large selection of popular cap options.

With PS22 liners, cosmetic disc liners, dome, metal caps and much more, we can certainly assist you in finding a great closure and liner option for your unique application. The clear PET square jars are an excellent way to show off your product on the shelf. Customers will be able to see the vibrant colors and textures of your products, which can be visually appealing especially when paired with a custom label.

The blue PET square jars can be used to package products that may have a slight sensitivity to light, as darker colored PET plastics can help to block UV rays. The blue PET square plastic jars could also add a splash of color when packaging less colorful items such as creams, nutritional supplements and seeds.

Wire Bale Style Square Jars

Wire Bale Style Square Jars

While many wire bale jars are available only in glass, SKS is happy to provide our 5 oz, 7 oz and 13.5 oz wire bale square jars in crystal clear PET plastic. PET plastic wire bale jars are less prone to breakage on the shelf and during shipment than glass options, and PET also provides great barriers for your product. You can purchase each size of the square wire bale jars separately in kit or bulk case packs, or as a convenient combo kit featuring all three sizes.

Wire constructions secure the lids to the jars and prevent them from being misplaced, while allowing fast access to the jars' contents. The rubber rings compress when the wire handles are in their fully closed positions, creating effective seals. The side and top panels of the wire bale jars could be enhanced with unique custom labels, while decorative twine or ribbons could be tied around the square jars' necks, adding additional accents.

PET Square Gripped Wide Mouth Jars

PET Square Gripped Wide Mouth Jars

These clear PET plastic wide mouth square jars feature built in grips on the jars' walls. Available in 1/2 and 1 gallon sizes with large 110/400 finish openings for easy dispensing, these square jars could be ideal for products sold in larger volumes such as rice, snack foods, or nuts and dried fruits.

The gripped side of the wide mouth square jars include convenient handles that do not extend outward from the jars' bases. This allows for easy handling and pouring, without the requirement of added storage and shelf space.

PET Plastic Properties

While PET plastic is very durable and versatile, it is always best to test your product specifically with the packaging you choose.

SKS has an extensive collection of information regarding PET plastic on our website. Here are some of the many reasons why it is one of the most popular plastics when it comes to packaging.

  • FDA approved and BPA free
  • The easiest type of plastic to recycle
  • Very high clarity
  • Good barriers against oxygen and moisture
  • Good resistance levels to grease, oil, impact, cold and sunlight
  • Can be easily coated and decorated
  • Maximum fill temperature (160° F)

Glass Square Jars

Glass Square Jars
Glass jars are versatile due to the nonporous and impermeable nature of glass. Glass is also completely recyclable for easy disposal when the jars are empty. Another great feature of glass jars is durability during heating. Glass jars can be used for packaging products that are hot filled or meant for continual heat, due to the inflexibility of glass at higher temperatures. While many types of plastic will start to warp and melt, glass jars retain shape and after cooling, and will not develop weaknesses at the mold lines or walls. Be sure to test the square glass jars you would like to use to ensure complete compatibility.

Our 7.5 oz candle style square glass jars stand 3" tall and are sold without lids. Consider using these glass candle jars for your line of scented candles. They could also be used for planting small succulents and plants.
Glass Square Jars w/ Lug Finish

Square glass jars are also available with a lug finish, rather than a standard continuous threaded finish. Available in four sizes, these square glass jars are compatible with gold, silver and red plastisol-lined metal caps.

A plastisol liner is a gasket, which can be activated through different canning processes, melting the liner onto the rim of the square glass jar. Once the plastisol liner is cooled, a tamper evident hermetic seal is created that prevents leakage and can extend the shelf life of your product.

Sleek, streamlined and unique in design, square jars are a great option to consider when choosing packaging for your products.
