Graham is a global leader in hot-fill packaging. Hot-fill refers to the process of filling packaging with heated, commercially sterile product. During the hot-fill process, the product is held for a predetermined time and temperature to sterilize it before it’s filled into the container. After the filling process, the container is immediately cooled, which is an extremely important part of preserving the product’s color and taste. Graham’s high-performance, hot-fill packaging can withstand temperatures up to 205°F and the resulting vacuum that occurs when the product cools down.

The hot-fill process is ideal for noncarbonated beverages and food products, like fruit and vegetable juices, sauces, sports drinks and teas. Hot-filled food and beverages can be stored in ambient conditions, unopened, for long periods of time without the need for preservatives. Our industry-leading, hot-fill PET and polypropylene packages, including our advanced ThermaSet® PET containers, deliver a long shelf life while also providing design flexibility for your brand.


Graham is a leading provider of aseptic packaging, producing more than 1 billion aseptic packages worldwide per year. Aseptic is an alternative to hot-fill or retort processing that doesn’t expose products to extended periods of high thermal temperatures. In this process, the package, the environment and the product are all sterile.

This process is ideal for low-acid products, as well as quickly perishable items, like dairy products. It’s also gained popularity due to the recent trend toward all-natural and organic beverages, since it eliminates the need for preservatives in the product while protecting color, taste, texture and nutritional value. Let Graham help you create an aseptic packaging design that keeps your product fresh in an attractive and sustainable package.


Graham is an expert in the area of retort packaging. In fact, we manufacture more than 1 billion retortable packages each year. The retort process sterilizes, cooks and conditions foods and beverages while they’re sealed in-package. In retort packaging, product is filled into the container, sealed and then heated to an extremely high temperature, which renders the product commercially sterile, a challenging environment for plastic packaging that Graham has successfully overcome.

This process protects foods and beverages that would spoil under normal storage conditions. Plus, since products are sealed in-package, retort packaging can also save time and money during the packaging process. Let Graham help you with this 360o solution that saves steps, time and budget.

High-Performance Packaging for Any Filling Process

In addition to hot-fill, retort and aseptic packaging, Graham has the knowledge and expertise to create high-performance packaging for a wide variety of fill processes, including ambient, cold-fill and high pressure processing (HPP).  We also have solutions for all types of closure systems, including threaded cap, induction/conduction weld, metal lug and more.

While these are some of the fill methods our packaging can be used in, it is by no means an exhaustive list. If you have questions about your specific product’s fill method, reach out to one of our experts to find a sustainable, stand-out packaging solution.
