Composite technology and specialized lamination

Customized composite process technology

We produce new functional films by laminating plastic film to metal foil or with a special process such as resin melting and first-surface decoration. We match customer needs through our high technology, joining even difficult-to-adhere materials to each other.

Major initiatives

PANAC provides both dry lamination via traditional adhesives and thermal lamination via heat melting of the film surface.
By laminating two or more layers of film or foil it is possible to take advantage of the characteristics of each material and achieve performance that the materials alone cannot generate.
In addition, we melt resins and coat them directly to materials or combine this with special processing such as surface embossing. We create optimal products and processing processes that meet customer needs.

<Adoption track records>
Shielding parts, damping parts, backlight parts, FPC, medical parts, electronic parts or materials, etc.

Secondary processing after the laminate: Check here for slitting, cutting or punching!

In-house development Characteristics of the composite technology

Developed our facilities so we can freely customize the process method up to customers’ need or material.

Possible to freely combine various unit or processing roll.

To part specifications’ change associated with market change, or to new needs, responding to flexible and speedy prototype・production.  ⇒Thermal lamination, resin coating, embossment, surface treatment etc.

All processing rolls are designed in-house.

Among various machine rolls, we select the roll that suits the processing need. If the processing is unsuitable with an existing roll we will design a new roll for production.

⇒Processing temperature Max 400℃, surface decoration (embossment) roll, surface special processing roll etc.

In-house development Characteristics of the composite technology

We can process film materials into all sorts of shapes and sizes.

Dry Lamination

This process applies adhesive on the plastic film that will be laminated. After the adhesive dried the film is press-bonded to its mating film.
Different materials such as plastic film and metal foil can be bonded together in this manner.

Processing specification Coating section cleanness class 1000, 10000
Material width limit max 1700mm
Material type Various plastic films, metal foil
Adhesive coating thickness (Dry) 0.1μm – 100μm
※2 heads continuous coating is possible
( undercoating + coating )
  • This process can laminate plastic films with different heat shrinkage rates or metal foils with different coefficient of linear expansion while still controlling film curl.
  • Voids and bubbles are prevented through the proper selection of adhesive and the use of our unique laminating technology.
  • Lamination of metal foil to metal foil is also available.
Materials laminated in the past

Various polymer films: engineering plastics (PET, PEN, PI, PPE, etc.), olefin film (PE, OPP, TPX, etc.), PMMA, TAC, other plastic films Various foils: SUS foil (12 – 100μm), Cu foil (12 – 70μm), Al foil (9 – 200μm), Ti foil, Fe foil, etc.


We can formulate adhesives with various properties as listed to meet customer’s requirements and applications.
Modulus control (Curl controlling and tracking the stretch of the substrate)
Chemical resistance (etching resistance)
Adhesive force control (ensures the adhesion between film or foil layers)
Enhanced functionality (rust prevention, antistatic etc.)

Thermal lamination

Without using conventional adhesive plastic films may be laminated material such as a plastic film is melted by heat, and bonded by pressure bonding processing. Materials that could not be bonded by dry lamination can also be processed.
As the laminated product does not have an adhesive layer, it can exert the inherent properties of the material (heat resistance, etc.).

Processing specification Laminating unit cleanliness Class 10000
Material width limit max 1400mm
Material types Various engineering plastics (PET, PEN, PI, PPE, fluorine film, etc.) , olefin-based film
SUS foil (10 – 100μm), Cu foil (12 – 70μm),
Al foil (9 – 200μm), Ti foil , Fe foil etc.
Hot melt sheet , fabric sheet, etc.
Heating temperature max 400℃

3 or 4 layer lamination is possible. 5+ layer lamination is available upon request. Lamination of high heat-resistant film is also available due to the capability of high processing temperatures (max 400℃).
Lamination also available for adhesive sheet by heat-melting.
It is also possible to laminate such as fabric materials with unevenness by unique press method and melting at high temperature and embedding.

Materials tried in the past

Polymer films: Various engineering plastics, olefin film, fluorine film, LCP film, glass cloth, etc. Metal foils: SUS, Cu, Al, Ti, etc.

Original Thermal Lamination Processing


We can carry out lamination processing such as metal-and-resin and
resin-and-resin, which could not be done with the usual lamination technology.


  • Lamination processing combining thermal lamination and surface modification processing.
  • With our thermal lamination technology, it is possible to form a thin film of fluorine resin (PTFE, PFA, FEP, etc.) on heat-resistant film, such as polyimide and metal foil.

Application examples

  • Heat-resistant separator
  • Heat-resistant release film
  • Antifouling treatment film
  • Water-repellent treatment film
  • Low dielectric material etc

Resin Melt Coating Processing


Coats or bonds directly to the material while melting the hot-melt resin.
Laminated products, single-layer products, compound products and so on are available.


  • Realizes high-thickness coating or high precision coating through our original coating method (thickness accuracy within ±2%).
  • Excellent smoothness on coating surface.
  • Hot melt coating thickness from 150 μm to 1000 μm. (Please contact us for thicknesses below 150 μm or above 1000 μm.)
  • Direct coating available for various substrates.
  • Available for low-viscosity resin films that cannot be processed through the extrusion method.
  • We will investigate the resin according to the customer’s application and request.

Decoration processing (embossing processing)


Embossing on the film surface
(Single-sided and double-sided simultaneous processing is possible)


  • Shapes that cannot be transferred during film production areimparted by high-temperature processing to material (biaxially stretched film such as PET film and OPP film).
  • Embossing processing on films with high heat resistance (limited to thermoplastic materials).
  • In-house design of embossed shapes to meet required characteristics.
  • Embossing from 20 μ to several hundred μ.
  • Random mat processing and pattern embossing processing (square, hexagonal, etc.).

  • Water repellency imparted by embossing.
*For difficult to process materials, we will develop a manufacturing process to suit your needs.

  • Film surface shape processing (Embossed film, embossed shape transfer application)
  • Reducing film surface energy (less sliding friction on smooth film)
