Technical film finishing
Film coating for self-adhesive film laminates
Krückemeyer combines suitable technical films with adhesive films or additional layers. The resulting film laminate is tailored to the application and subsequent processing.
01
Film coating
How a film becomes an application-specific laminate
Film coating joins a suitable technical film to an adhesive film or another material layer. An adhesive transfer film can make the film self-adhesive. A liner protects the adhesive layer until processing and affects subsequent handling.
The right combination depends on the film, its surface, the required adhesion and the next production step. The layers are specified for the particular application. Coating does not automatically give the film new material properties. We will clarify with you whether the manufacturer's approval still applies to the coated film laminate.
We discuss the required function, intended bonding surface and delivery format with you. Surface pretreatment may be necessary; its suitability is checked against the actual starting material.

From film requirement to laminate
Step 01
Describe the application
Tell us about the film, bonding surface, required function, dimensions and delivery format.
Step 02
Assess the material structure
We assess the film surface, adhesive film, liner and suitability of the proposed layer sequence.
Step 03
Agree the delivery format
We clarify whether roll goods or suitable sheet goods are needed and how the material will be processed next.
Step 04
Produce the film laminate
After technical clarification, suitable layers are joined and supplied in the agreed format.
03
Possible film coating structures
Make film self-adhesive
A suitable adhesive transfer film prepares the film for the intended bond. The adhesive layer and liner are selected for the surface and processing.
Combine films with further layers
Technical film can be combined with suitable films or other material layers. Layer order, processability and the desired result determine the structure. Explore film lamination →04
Possible delivery formats
Coated film on a roll
An agreed film laminate can be supplied as roll goods for further processing. Dimensions and winding depend on the structure. Enquire about roll goods →
Suitable laminate in sheets
Suitable sheet material can be coated and prepared for subsequent processing. Format and structure are assessed individually. Enquire about sheet goods →
Die-cut parts from coated film
Suitable film laminates can be die-cut after the film, adhesive layer, liner and required geometry have been assessed. Shape and delivery format depend on your application. Enquire about die-cut parts →05
Assess suitable starting materials
Technical plastic films
Technical films are possible starting materials. Their surfaces and the desired adhesive film determine whether pretreatment is needed. Explore film processing →
Adhesive transfer films
Carrierless adhesive films can form the adhesive layer of a film laminate. Suitability depends on the surface, application and processing.
Other suitable material layers
Combinations with foam or adhesive tape may also be possible. Each bond is assessed against the actual materials and required function. Explore tape lamination →06
Film finishing and laminate
07
What determines the coating choice
| Selection point | Question for technical assessment |
|---|---|
| Film and surface | Which film and surface need finishing? |
| Adhesive layer and liner | What adhesion, protective liner and later handling are required? |
| Layer sequence | Which layers need joining and what function does each layer serve? |
| Delivery format | Which dimensions, roll or sheet format and subsequent process are needed? |
The film, adhesive film and delivery format are assessed against the starting material and application.

Details for your film coating enquiry
Describe the application and intended function of the coated film: Which surface must bond, to which substrate and under what service conditions? Specify the starting film, desired layer structure and any existing adhesive film or liner.
We also need dimensions, preferred delivery format and quantity for production assessment. A drawing or sample helps us assess the surface, layer sequence and subsequent processing together.

Film coating questions
What does film coating mean at Krückemeyer?
Film coating here means joining suitable technical films with an adhesive film or another material layer. This can make a film self-adhesive or prepare it as a multilayer laminate for further processing. The precise structure depends on the application.
When is pretreatment of the film surface useful?
Pretreatment may be needed if the proposed adhesive layer does not bond sufficiently to the film surface. Corona treatment is one possible preparation for difficult-to-bond surfaces. Its suitability for the actual starting material is assessed before production.
Can the coated film be cut afterwards?
Yes, suitable film laminates can be processed after coating. Whether cutting or die-cutting is appropriate depends on the film, adhesive layer, liner, layer sequence and required geometry. The process is chosen after assessing the actual structure.
Do the original film properties and approvals remain valid?
This cannot be assumed generally. An added adhesive layer or another material layer changes the structure. Whether an original manufacturer approval or a function-critical property still applies to the coated laminate must be clarified for the material and application in the particular project.
