Extrusion lamination is a process in which a molten thermoplastic resin is extruded through a flat die and used as an adhesive layer to bond two or more substrates together. Instead of using solvent-based or water-based adhesives, the molten polymer itself acts as the bonding medium. The extruded resin is applied between substrates and immediately pressed together through a chill roll and pressure nip, forming a strong laminated structure.


In practice, this means laminating barrier films , Aluminum Foil, Met-BOPP, Met-BOPET to printed bi-oriented films like BOPP, BOPET, and BOPA, then sealing with PE/PP webs.

The process runs at 320–330°C using a high-flow LDPE resin (MFI 6–8), typically blended at 6–25% with specialty adhesion polymers (acrylate or POE based) to guarantee adequate bonding.


🔶 Introducing TL 4114 - Polyram's direct replacement.

Our mLLDPE-based grade TL 4114 replaces acrylate and POE specialty polymers at identical blend percentages, with no process changes required.

✅ Cost efficiency - mLLDPE-based chemistry delivers meaningful raw material cost reductions vs. acrylate or POE alternatives.

✅ Adhesion that meets or exceeds benchmarks - validated mechanical performance across all key lamination structures at 320–330°C.


📦 Four proven structures with TL 4114:

🔹 Met-BOPET // LDPE+TL4114 // LLDPE

→ High stiffness, O₂ & light barrier | Snacks, coffee, dry food

🔹 Met-BOPA // LDPE+TL4114 // LLDPE

→ Maximum puncture & flex crack resistance | Frozen meat, sharp-edged products

🔹 BOPP // LDPE+TL4114 // Alu Foil // LDPE+TL4114 // sealing

→ Highest barrier; TL4114 acts as "shock absorber" between OPP and brittle foil | Coffee, long shelf-life food

🔹 BOPP // LDPE+TL4114 // Met-OPP // LDPE+TL4114 // LLDPE

→ Cost-effective, lower density | Chips & oily/moist snacks

Today's KNOWLEDGE Share : Robotic 3D printing can compete with traditional boatbuilding

Image
Today's KNOWLEDGE Share “Robotic 3D printing can compete with traditional boatbuilding”, Simone Barbera and Mattia De Santis, Caracol V2 catamaran was printed in Italy at Caracol’s production center and headquarter in Barlassina, near Milan, with a Heron AM 400, Caracol’s robotic Large Format Additive Manufacturing (LFAM) platform. The lattest was specifically configured with a 7-axis robotic arm mounted on a rail, enabling the printing of parts up to 10 meters in length. How did the collaboration between V2 Group and Caracol come about? Simone Barbera : The collaboration between V2 Group and Caracol originated from a shared vision to revolutionize boat manufacturing through sustainable innovation. V2 Group, a Spanish-company specialized in nautical design and engineering, is seeking to develop electric vessels manufactured sustainably. On the other hand, Caracol, leader in robotic advanced manufacturing technology, had had years of experience working with Large Format Additive Ma...

Today's KNOWLEDGE Share : What Is Going Wrong in UK Plastics Recycling?

Today's KNOWLEDGE Share What Is Going Wrong in UK Plastics Recycling? Biffa shut its Sunderland plant. Viridor walked away from Avonmouth and Rochester. Yes Recycling Fife collapsed within a year. All three were backed by major investments All three had buyers lined up for recyclate All three are now offline This is not bad luck It is bad structure Over the next four posts I will break down: 1. Why cheap virgin imports are undercutting UK recyclers 2. How weak policy enforcement is fuelling market failure 3. What volatile PRNs and cheap exports are doing to infrastructure 4. Why demand from brands is softer than their promises Let’s start with the first: **Cheap Virgin Resin = Broken Economics** Virgin PE, PP, and PET have been flooding the global market. New capacity in Asia and the US has driven prices down 30 to 40 percent. Meanwhile, recycled plastic costs more to produce in the UK than it can sell for. We are asking UK recyclers to compete with materials made in places with – ...

Today's KNOWLEDGE Share : A BUG IN INJECTION MOLDING

Image
Today's KNOWLEDGE Share A bug in injection molding – an injection-molded part in a bug? Neither! Nature and injection molding have reached similar results. Nature created the first micro-gear long before any human engineering existed. One such example is the Issus coleoptratus (shown in the picture). Furthermore, only now are we reaching the point where injection-molded polymer microgears can approach this level of performance. Looking at the images, which one do you think is the natural gear, and which one is the molded version? It is not that easy to tell, right? Their appearance and operating principles are surprisingly similar. Chitin, a natural linear polymer, forms what nature essentially "molds” into shape. In engineering, we rely on advanced technical polymers to produce similar geometry through actual injection molding. They are not the same material, yet they solve the same issue: Stiffness, dimensional stability, and reliable function at a scale where tolerances...
