McKernan carries millions of packaging components including glass jars, plastic jars and candle glass that come in a variety of sizes and colors.

Airless Jars

An airless jar is a great packaging choice for sensitive or preservative-free products. They provide shelf-stability and formula protection, reducing the need for chemical preservatives. This innovative jar minimizes air exposure, which increases shelf life, in some cases as high as 15%. With a simple press of the pump, the airless delivery system dispenses a precise amount of product, creating little to no waste. Airless jars are the perfect choice for quality products needing an enhanced delivery system.

Glass Food Jars

Glass is by far the preferred packaging for food due to the overall safety. The nonporous surface resists germs and odors. Having a high resistance to heat makes it perfect for canning. Glass is 100% recyclable and an excellent choice for all foods. With various shapes, sizes, colors and finishes, glass food jars create an open invitation to get creative.

Glass Cosmetic Jars

Glass, one of the oldest packaging materials, is still proving over and over to be a favorite in the industry. This nonporous and inert material makes for the perfect cosmetic jar. Many in the cosmetic industry want to reduce the impact of plastic pollution, therefore, more and more are turning to the highly recyclable glass package. For its sheer classic beauty, glass will remain a top choice in the cosmetic industry.

Single & Double Wall Jars

Single wall plastic jars are made of one piece of plastic, while double wall jars are constructed of two pieces of plastic. Both can be Polypropylene (PP), Polyethylene Terephthalate (PET), Polyethylene (PE) or Polystyrene (PS). They can come in a variety of colors and shapes. This versatile jar is used in a broad range of industries, from personal care to pharmaceutical and everything in between. Overall, single and double wall jars are affordable, durable and economical to ship.

Thick Wall Jars

Thick wall jars are molded from a single thick piece of plastic for extra strength and durability. There are various plastics used for thick wall jars including PET, PETG, PP and PS. When polyethylene terephthalate glycol (PETG) is used, the thickness and flawless clarity give the illusion of glass, thus making a beautiful package without the heavy shipping weight and fragility of glass. This style of jar is a great choice for the cosmetic and personal care industry.

Plastic Food Jars

Known for being notoriously inexpensive, plastic will always be a front-runner for food packaging. Lightweight, strong and durable are all good characteristics, then add in low freight costs and you have a winner. There are many different plastics, which are BPA free and safe to use, but polyethylene terephthalate (PET) will always be the favorite with crystal clear beauty that closely resembles glass. With limitless shapes, colors and sizes, plastic is a great option in the food & beverage industry.
