Technical adhesion for converting
Adhesion primers for coatings, extrusion, and metallization
Designed to create a reliable interface between the substrate and the functional layer. They improve anchorage on film, paper, and aluminum foil, and help build laminations, extrusions, and metallized structures with greater stability.

What they make possible
An adhesion base for coatings and extrusion
The right primer does more than bond two surfaces. It also stabilizes converting, protects the interface, and creates room to add extra functions when the structure requires them.
Bridge for functional coatings
They prepare the surface to receive acrylic, seal, barrier, and other coatings that demand uniform anchorage.
Improve wetting and anchorage between the substrate and the functional layer.
Reduce delamination risk when the structure moves through printing, converting, or end use.
Can fit systems where adhesion and barrier need to coexist.
Stable interface for extrusion
They act as an anchor layer for polyethylene families, EVA, and ionomer-type resins in extrusion or extrusion coating structures.
Hold adhesion across low and high thermal windows.
Support anchorage on film, paper, and foil without demanding radical line redesigns.
Help maintain uniformity when the process requires speed, temperature, and consistency.
Performance beyond anchorage
In some architectures, the primer can also contribute extra functions to simplify the structure.
Some options also contribute oxygen and mineral oil barrier.
They can improve adhesion over metallic layers or other critical interfaces when the structure demands it.
Fewer sensitive interfaces mean more control over final packaging behavior.
Where they work
Applications that need controlled adhesion
From dry packaging to structures exposed to moisture, chemistry, or metallization, the right primer defines how much the interface can withstand.
Primers for functional coatings
Designed for structures that receive one or more downstream layers and need consistent anchorage from the first pass.
Primers for extrusion and lamination
Developed to maintain the bond between the substrate and the extruded resin when the structure needs a more robust anchor.
Substrates they can cover
Final selection still depends on surface energy, construction, and the technical target, but these are the most common starting points.
Film
For flexible structures that require adhesion between layers, metallization, or barrier coatings.
Paper
When the pack needs extra functions without losing convertibility or appearance.
Aluminum foil
Useful in structures where metal anchorage and interface integrity are critical.
What they can achieve in practice
Dry goods and low-moisture packs
They help build efficient structures when the main requirement is reliable adhesion with low failure risk.
Humid or demanding environments
Performance profiles are available for structures that need stronger resistance to water, chemicals, or operational stress.
Metallization and topcoats
They improve anchorage before or after metallic layers when barrier and visual integrity are sensitive.
Laminations and extrusion coating
They stabilize interfaces that later need to withstand converting, filling, sealing, or transport.
How to choose
Two performance routes for different demands
Not every structure needs the same primer. In practice, selection usually moves between general-efficiency profiles and reinforced-protection profiles.
General performance
Best suited for dry applications, low moisture, and structures that prioritize efficiency with solid adhesion.
Coverage across the most common flexible converting substrates.
Good adhesion for functional layers and extruded resins in standard constructions.
Efficient application windows for highly repeatable processes.
Ideal when the structure does not face severe water or chemical attack.
Reinforced protection
Oriented to structures that must withstand water, chemicals, metallization, or heavier operating demands.
Stronger interface resistance in aggressive or high-humidity environments.
Better support for critical functional layers and more demanding constructions.
Good response when the structure combines adhesion, barrier, and process stability.
Useful for reducing failure risk when the package operates at the edge of the application.
Operational benefits
What your process gains
Beyond the lab, a good primer reduces plant uncertainty and speeds up technical validation.
