Instead of forcing a product to fit pre-cut foam, expanding packaging foam forms to the product and available space inside the carton.
How does expanding packaging foam work?
Mixing two components starts a chemical reaction. The material increases in volume, conforms to the surrounding geometry and cures into a supporting foam form. Reaction time may vary with material and ambient temperature.
Safe application: Liquid components must not contact the product directly. Support is formed through the sealed protective outer bag.
What does foam-in-bag mean?
Foam-in-bag means that the reaction takes place inside a sealed outer bag. The bag is positioned in the carton and the product is placed on or between supports while the foam takes its shape. NCpack provides this process without a dedicated dispensing machine.
- 1
Mix
Combine the two components inside the pack until uniform.
- 2
Position
Place the sealed outer bag at the required support area.
- 3
Form
Position the product so the expanding foam creates the intended support.
Main benefits of expanding foam
- Conforms to irregular and unique product shapes.
- Supports service, repair and return shipments without original packaging.
- Reduces the need for dedicated tooling in low-volume or variable applications.
- Helps fill voids while restraining the product in planned directions.
- NCpack requires no foam dispensing machine or compressor.
Where is it used?
Typical applications include electronics, measuring and optical equipment, glass and ceramics, custom-manufactured parts, motors, industrial equipment, photo-video equipment and second-hand shipments. The suitable series and code depend on product sensitivity and weight.
How are quantity and placement selected?
Product dimensions, inner carton dimensions, weight and required support directions are assessed together. Large or heavy items may need multiple bottom, side and top supports rather than one oversized pack. A sample application confirms the final selection.
