Other custom flexible packaging formats
Flexible packaging roll film can be manufactured using single-layer, multilayer, laminated, co-extruded, metallized, or recyclable structures.
The appropriate structure depends on the product, required shelf life, packaging machine, and performance requirements.
Why Is Flexible Packaging Becoming More Popular?
Modern packaging needs to satisfy several requirements at the same time.
Brands want packaging that is:
Lightweight
Attractive
Functional
Cost-efficient
Easy to transport
Suitable for automated production
Capable of protecting the product
Adaptable to sustainability goals
Flexible packaging roll film can address many of these requirements through customized material structures.
Instead of using one material for every application, manufacturers can combine different films to create a packaging structure with specific properties.
For example, one layer may provide printing performance, another may improve mechanical strength, and another may provide heat sealing.
This allows the packaging to be designed around the product rather than forcing every product into the same packaging format.
What Are the Main Advantages of Flexible Packaging Roll Film?
Flexible packaging roll film offers several advantages for modern packaging operations.
1. Lightweight Packaging
One of the most obvious advantages of flexible packaging is its relatively low weight.
Compared with many rigid containers, flexible packages can use less material while still providing the required product protection.
