FLAME LAMINATION
The flame lamination process involves connecting two layers of textile materials , imitation leather , barrier foils or other flexible components using polyurethane foam.
Kora Textiles offers flame laminated textile materials and a flame lamination service. The products offered by our company are manufactured on the most modern machinery available in Poland and Europe.
The huge flame lamination line is equipped with the necessary supplies for materials glued on both sides and foam . The use of supplies in the case of production of large batches of materials allows to reduce the number of technological errors.
The laminating line is also equipped with a state-of-the-art pattern straightener and a system for printing the inner side of the resulting laminate in order to fully identify the quality of the product .
What is lamination?
Lamination is the joining of different materials using laminating machines . It preserves the individual properties and characteristics of each layer. Laminated materials have better strength, stability, durability, comfort and appearance as a whole.
Lamination is used to join materials such as foams, fabrics, PVC foils, leather, artificial leather, non-woven fabric, foil, paper, metal, honeycomb or other materials. During the lamination process, factors such as machine heat, pressure, time and quality of glue and material are important .
The most versatile manufacturers of advanced materials produce a variety of laminate solutions using a wide range of processes, such as heating, pressure, welding or gluing. We focus on a very efficient and effective method, flame lamination.
Flame Lamination Process
Flame lamination is the process of laminating flexible materials with heat generated by an open flame. Generally, a layer of core material (such as polyurethane foam ) will need to be exposed to an open flame to develop tackiness to then adhere to another layer, such as fabric or vinyl.
In the case of foam and fabric, the rolled foam products are passed through an open flame, and the side exposed to the heat melts slightly and becomes sticky. It is then immediately bonded to the fabric, and the two stick together without the need for additional adhesives .
This process provides added functionality and versatility with fabric on one side and nonwoven on the other, fabric on both sides, and many variations of fabric combinations to create composites including foams, films and knits.
These combined composite materials will have properties and characteristics that the individual layers would not have on their own. It is worth considering whether such versatility would be beneficial to your requirements.
Benefits of Flame Lamination
- Efficient process : It is a cheaper and more efficient process than other laminating alternatives. The process is fast and productive.
- Material versatility : a very effective method of bonding flexible foams (most often polyurethane) and some nonwovens to a wide range of other substrates, including fabrics, foils and papers, as long as the core material is flame laminated
- No gluing required : the process does not require additional gluing technologies, with a wide range of possibilities to join materials in one step. This absence reduces the total cost
- Sustainability : The lack of glue improves its recyclability and reusability as one less component needs to be separated.
- Multi-layer capability : You have the versatility of composites by creating a laminate on one or both sides of the core material.
- Variable thickness : Composites can be as thin as 1.9 cm, and some applications may not require any additional thickness, using only a very thin layer of polyurethane foam
With its versatility, speed and lower costs, flame lamination can be a powerful composite process.
PU foam is most commonly used in flame lamination due to its unique properties (soft, flexible, etc.). Flame bonding can maintain its flexibility and softness .
In applications, flame lamination is widely used in automotive seating, public transportation, footwear, upholstery and other industrial applications.
