Flexible Polyolefins may be the perfect choice for your products.
Polyolefin is a preferred plastic resin used in the manufacture of plastic containers. It's easy to dye and mold, and is a non-polar, odorless and nonporous material. Polyolefins offer many material choices with applications that encompass virtually every product, venue and industry. Polyolefin is lightweight, absorbs added color effectively, provides thermal stability for hot-fill and cold-fill items alike, and is recyclable. Common Polyolefins are Polypropylene and High-Density Polyethylene (HDPE).
Graham experts can match the polyolefin process to your needs with precision. So you get the perfect container for your product. And our proprietary machine platform portfolio and extensive global plant network provides flexibility for volume, size, and manufacturing location. There’s never guesswork with Graham. Our solutions are tested against the toughest standards. Every time.
Graham has decades of co-extrusion experience producing world-class quality containers. Our proprietary multi-tube flow head systems enable high speed production with minimum material variations. We employ traditional blowmolding polyolefin resins as well as barriers, inorganic fillers, PCR, colorants, and other exotic materials.
We’re an industry leader in hot fill polypropylene packages. Hot fills create a sterile, shelf-stable package primarily used to preserve high-acid foods and beverages.
Cold-fill is a filling process used for many fresh products such as milk and fresh juices. Polyolefin containers provide the convenience of blown-in handles and organoleptic properties that don't interfere with the flavor or taste of the product. Since the performance requirements are less than hot-fill, retort and aseptic, there is more design freedom with packages used in cold-fill applications.
- High density
- Provides for better product taste
- Multi-layer technology for flavor protection
Worldwide, we currently produce more than 1 billion aseptic packages. Packages are rinsed with a sterilant and filled in an aseptic environment to maintain sterility. It’s typically used as an alternative to high-temperature sterilization for quickly perishable items like dairy products.
More than 1 billion retortable packages are manufactured by Graham each year. The retort process sterilizes, cooks, and conditions food and beverage products while sealed in-package. It’s a 360◦ solution that saves steps, time and budget.
