Causes and Solutions for Insufficient Bonding Strength in Extrusion Laminators 6
Improper Cooling and Solidification
What is an Extrusion Coating and Lamination Machine? An extrusion coating and lamination machine is an industrial system used to apply a "plastic raincoat" to substrates such as paper, paperboard, non-woven fabrics, woven fabrics, and aluminum foil.
Its core function can be summarized as follows: it melts plastics like polyethylene (PE) and polypropylene (PP) at high temperatures and coats them uniformly onto the substrate surface. This creates a protective film layer that provides waterproofing, moisture resistance, oil resistance, and enhanced structural strength.
Process Overview The typical workflow of an extrusion coating line follows this sequence: Unwinding β Pre-heating β Corona Treatment β Extrusion Coating β Cooling β Edge Trimming β Rewinding
Driven by a screw extruder, plastic resin pellets are heated and melted. Once extruded through the die, the molten plastic cascades down like a "waterfall" onto the substrate surface. After being hot-pressed and cooled, the plastic layer bonds securely with the substrate. The entire process is highly automated, with production line speeds reaching 100β150 meters per minute or even higher.
Core Advantages of Extrusion Lamination Machines
Laiyi Lamination Machine Knowledge Guide
Eco-Friendly and Safe Zero Solvent Residue: Since it does not utilize organic solvent-based adhesives, it fundamentally eliminates VOC (Volatile Organic Compound) emissions and solvent retention issues.
Food Packaging Friendly: It is particularly well-suited for fields with stringent safety and hygiene standards, such as food and pharmaceutical packaging.
Aligned with Green Trends: It eliminates the need for auxiliary solvent recovery systems or RTO (Regenerative Thermal Oxidizer) incineration systems.
High Cost-Efficiency Eliminates Adhesive Costs: It replaces expensive laminating adhesives with cost-effective raw resin pellets (such as PE or PP).
Optimized Energy Consumption: Without the need for high-energy long drying tunnels, its overall energy consumption is typically lower than that of dry lamination.
Simplified Material Sourcing: Resin raw materials enjoy a stable supply chain and relatively predictable price fluctuations.
Integrated Functionality Dual-Purpose Interlayer: The extruded resin layer simultaneously acts as the bonding agent, heat-seal layer, and moisture barrier.
Single-Step Forming: It shortens the process chain by transforming raw pellets into finished laminated structures in one continuous run, maximizing production efficiency.
Ideal for Mass Production: It delivers exceptional economics for high-volume products with standardized structures (e.g., aseptic milk cartons, instant noodle packaging).
High Production Efficiency High-Speed Operation: Typical production speeds range between 100β300 m/min, significantly outperforming dry lamination.
Seamless Roll Changing: Because it requires no curing time or solvent evaporation waiting periods, it excels at continuous, heavy-duty production runs.
How to Maintain Lubrication for Extrusion Coating Machines?
Laiyi Extrusion Coating Machine Knowledge Sharing Regularly add lubricating oil to all lubrication points, and select lubricants suitable for the working environment. Pay special attention to the lubrication of the bearings at both ends of the heating roller and the gearbox reducer. Apply high-temperature resistant grease (such as molybdenum disulfide grease) to transmission components like screws and other drive parts.
