What is Primary Packaging?
Primary packaging is the first layer of packaging applied directly to the product. This can include film wrapping, tray sealing or bagging, depending on the product type and required presentation.
It plays a key role in protecting the product, maintaining shelf life and ensuring consistent presentation during handling and distribution.
The correct system is selected based on the product, required output and how it will be handled within the production process.
Primary Packaging Machine Types
Flow Wrap Machines (HFFS)
(Flow-Wrap/ Pillow Pack)
Used for wrapping products in continuous film, providing consistent output and high-speed packaging.
Vertical Form Fill Seal Machines (VFFS)
(Vertical Form, Fill and Seal)
Used for packaging free-flowing products into bags or pouches, with consistent fill and seal control.
Tray Sealing Machines
Designed for sealing pre-formed trays, providing secure and hygienic packaging for fresh and prepared products.
Thermoforming Machines
Used for forming trays from film and sealing them in-line, suited to high-volume packaging applications.
Vacuum Packaging Machines
Used for removing air and sealing products to extend shelf life and protect product integrity.
Choosing the Right Primary Packaging System
The type of primary packaging required depends on the product and how it needs to be handled. Factors such as whether the product is solid, liquid, fragile or perishable will determine the most suitable packaging method.
Shelf life is also a key consideration, particularly for fresh or sensitive products where controlled environments or vacuum packaging may be required.
Packaging format will vary depending on the application, including trays, bags, film wrapping or vacuum-sealed packs. The level of automation within the production process must also be considered, whether standalone machines or fully integrated systems are required.
