Different Types of Foam Lamination
Different Types of Foam Lamination
Adhesive lamination
As the name suggests, adhesive lamination is carried out using a strong adhesive substance that’s distributed across the material to be bonded, often using rollers. Some adhesive lamination processes also require heat – but not all do. These processes tend to be quicker than thermal lamination and produce strong, resilient materials with enhanced structural performance.
PSA lamination
PSA lamination is a specific type of adhesive lamination process. It essentially consists of applying pressure-sensitive adhesives (PSAs) to the foam substrate, along with a liner, in order to form the resulting composite foam material.
PSA lamination typically produces laminated foam with a high bond strength, making it an ideal process for those of you looking for an incredibly durable product.
The only downside is that the adhesive used can add weight and could give off harmful chemical gasses, depending on where the resulting material will be used, so if you’re looking for a lightweight material or are looking to create healthcare products likely to be exposed to heat, other types of lamination process may be better.
Heat lamination
Heat is used in many types of lamination processes, in order to create a bond between the different material layers or substrates. There are many different types of heat lamination processes, the most common of which are outlined below.
Hot-melt lamination
Following on from the adhesive lamination process discussed above, hot-melt lamination is the process of heating up an adhesive substance like hot glue before spreading it across the materials to be bonded together using hot rollers. The adhesive can either be applied as a continuous layer or in a specific dotted pattern.
At Archbond, we use PUR hot-melt adhesives to produce both glossy and matte laminated foam materials, whether you’re looking to create large-surface products like mattresses or need strong foam materials for use in HVAC systems. The major advantage of hot-melt lamination is that the end material can be created quickly, as it solidifies as soon as the industrial adhesive has cooled.

Flame lamination
Flame lamination is another type of thermal lamination process. Unlike hot-melt lamination, which requires the use of a separate adhesive, flame lamination can be carried out using just the substrates to be bonded. One layer of substrate is basically exposed to an open flame, in order to create a thin layer of molten polymer across the surface. Another layer of substrate is then placed on top of it, before running the whole thing to compress it together. As soon as both materials have cooled, they will be successfully bonded.
The strength of the resulting laminated foam will ultimately depend on how close your substrate materials were to the open flame and how quickly they passed through. The process tends to work best when bonding flexible layers of foam to non-woven fabrics but it’s also ideal for bonding foam to paper-based products and films.
The main advantage of flame lamination is that it doesn’t require any adhesive. Not only does this reduce costs but it also makes the process more sustainable, in addition to producing an end material that’s easy to recycle. Often performed using PU foam, this quick and efficient process produces a flexible material in less time than it would take with comparable lamination processes.

Infrared lamination
The infrared lamination process is similar to flame lamination, in that it doesn’t require any adhesive. It’s therefore another cost-effective, sustainable solution for creating your ideal composite materials. The difference is that rather than using an open flame, the different layers of substrate materials will be exposed to infrared radiation before being compressed together. This is an incredibly safe process that doesn’t present any risks, either before, during or after completion.
The infrared lamination process is ideal for creating a stable bond between different substrates of materials. It creates incredibly durable laminated-foam-based products, which are highly protective, making them ideal for use in a variety of industrial uses, including the automotive sector.

Water-based foam lamination
Some companies also conduct water-based lamination processes. However, this relatively new method tends to be less common than other lamination techniques. It’s incredibly eco-friendly and can be used to bond a variety of materials together.
Which foam lamination process is best?
As you can see, there are several different reliable methods for manufacturing high-quality laminated foam. The method you pick will ultimately depend on the strength and firmness of the material you want to create.
Adhesive lamination can be used to create strong, resilient materials with a firm structure. However, the process can take a little longer than other methods, so it may not be the best choice if time is of the essence. The resulting materials also tend to be a bit more weighty, so opt for something like flame lamination if you’re looking for softer, lighter foams.
The flame lamination process is also more environmentally friendly than adhesive lamination, as is infrared lamination, which comes out on top if you’re looking for a fast, sustainable process that will give you composite foam with high levels of industrial protection.
