What is the Definition of Flexible Packaging?
Flexible packaging has gained market share from rigid packaging as a result of a number of factors including advances in technology, lower costs due to lower materials consumption. The flexible packaging market has been driven by an expanding economy with businesses seeking more flexible packaging alternatives to market their products. A shift in trends and valuable packaging technology has helped make flexible packaging an affordable alternative to traditional, rigid packaging.
Flexible packaging is a package or container made of flexible or easily yielding materials, which when filled or closed, can be readily changed in shape. The construction may be of paper, plastic, film, foil, or any combination of these.
Common Industry Terms and Definitions:
As with any industry, there are numerous terms associated with flexible packaging that are important to know. Here are some terms and definitions that you may see and hear:
- Blister Packaging: Blister packaging contains the product between a formed dome and a flexible surface or paperboard.
- Fitment: A fitment is a device that attaches to a container to provide a specific function to the product, such as dispensing a liquid or foam. For example, a fitment might be attached to a liquid cleaner container.
- Four Side Seal Pouch: Pouches with seals along all four edges. The flat sheets of the pouch can come from a single stock or different stocks for the front and back.
- Good Manufacturing Practice (GMP): GMP is a process by which the product is manufactured in such a way that any risk to the consumer has been minimized. Some GMP processes are guided by federal and state regulations, while others are considered best practice principles.
- Gusset: A gusset is a fold on the bottom or side of a pouch, which expands the pouch when contents are inserted.
- Hermetic Seal: A hermetic seal is a flexible packaging term that refers to material that is impervious to fluids or gases and/or is airtight under normal circumstances.
- Lap Seal: Created with two layers of film that overlap each other, a lap seal uses less material than other seals, which makes a lap seal a better eco-friendly alternative in flexible packaging.
- Light Resistance: When a material can withstand exposure to light without changing the chemical properties, physical properties or color, it is considered light resistant.
- Pouch: Pouches are defined as a small bag consisting of two flat sheets that seal along the edges.
- Pillow Pouch: A pillow pouch is a pouch or bag that looks like a tube with a seal at both ends.
- Stand-Up Pouch: A stand-up pouch with a wide base to allow the pouch to stand up without tipping over.
- Three-Side Seal Pouch: A three-side pouch has three sealed sides with an open side, often with a seal.
- Unit Dose Package (UDP): Commonly used in pharmaceutical products, a UDP holds individual items separate from each other.
