Cold-seal flexible packaging is ideal for protein bars, breakfast bars, chocolate bars, nutritional bars, natural foods, ice cream novelties, and other heat-sensitive items.
We manufacture cold-seal flexible packaging by applying a water-based coating that adheres to itself and requires no heat to initiate a seal.
The advantages of cold-seal packaging
The seal strength and integrity are equivalent to that of heat-seal structures. But because cold-seal packaging requires no heat during the form/fill/seal process, cold-seal technology provides several advantages, including:
Cold-seal packaging line speeds can be multiple times faster than heat-seal line speeds.
It allows for immediate packaging line startup (as opposed to waiting for the packaging line to heat up).
Product spoilage due to packaging burn through is eliminated.
If the packaging line stops, heat-sensitive products will not get damaged due to the heat-sealing equipment.
Package distortion due to heat will be eliminated.
Energy costs are reduced. When using cold-seal packaging you no longer need to waste energy maintaining high temperatures on your heat-sealing equipment.
Operator injuries due to burns are eliminated.
Cold-seal flexible packaging can run on existing heat seal lines with heat turned off, which means lower energy costs. And faster line speeds = more throughput = more profit.
Also known as “bar wraps”, cold-seal packaging is designed to be run on horizontal form/fill/seal equipment.
Common applications for cold-seal packaging include:
