Frequently Asked Questions
Common questions about the WSL series solventless laminating machine
Q1
What is a solventless laminating machine?
+
A solventless laminating machine bonds two or more flexible films using 100% solids adhesive with no solvent and no drying oven. Because nothing evaporates, there is no solvent residue, energy use is lower, and lamination speed is higher, making solventless lamination the leading eco-friendly choice for food-safe flexible packaging.
Q2
What is the difference between solventless and dry (solvent-based) lamination?
+
Dry lamination uses solvent-diluted adhesive that must pass through a drying chamber, while solventless lamination applies 100% solid adhesive directly with no drying required. Solventless offers lower energy cost, faster speed, and zero solvent residue; dry lamination still suits certain high-performance structures like retort packaging. Worldly manufactures both machine types.
Q3
Is solventless lamination safe for food packaging?
+
Yes. Since no solvent is used, there is no risk of residual solvent migrating into food, and the process conforms to food safety regulations. This is why solventless laminating machines are widely used for snack bags, coffee pouches, frozen food packaging, and other direct food-contact flexible packaging.
Q4
What materials can the WSL solventless laminating machine handle?
+
The WSL series laminates PET, OPP, CPP, PP, PE, PVC, nylon, aluminium foil, and paper. This covers most common flexible packaging structures, from clear snack films to high-barrier foil laminates such as alu-alu cold form foil and coffee packaging.
Q5
What is the laminating speed of the WSL series?
+
The WSL series solventless laminating machine runs at laminating speeds up to 300 m/min with a maximum machine speed of 310 m/min, in web widths of 1000, 1200, or 1300 mm. The five-roll coating system maintains a uniform, ultra-thin adhesive layer even at full production speed.
Q6
How does solventless lamination reduce production cost?
+
Cost savings come from four directions: no solvent purchase, no adhesive lost to evaporation, a much thinner adhesive coating weight thanks to 100% solids, and no drying chamber, which cuts energy consumption significantly. The shorter machine footprint also frees up valuable factory floor space.
Q7
What adhesives are used on a solventless laminating machine?
+
Solventless machines typically use two-component polyurethane (PU) adhesives that are mixed and metered automatically before coating. The adhesive cures by chemical reaction rather than solvent evaporation. Worldly's five-roll coating system precisely controls coating weight for consistent bond strength across the full web width.
Q8
How long does solventless lamination take to cure?
+
Laminated rolls are typically cured at controlled room temperature for around 24 to 48 hours before slitting or pouch making, depending on the adhesive system and structure. During curing, bond strength develops fully. Your adhesive supplier's data sheet determines the exact schedule for each structure.
Q9
Can the machine laminate aluminium foil?
+
Yes. Aluminium foil is one of the standard materials for the WSL series, used in structures such as alu-alu foil for pharmaceutical packaging and foil-based coffee and food pouches. The machine's precise tension control protects the fragile foil web throughout unwinding, laminating, and rewinding.
Q10
What is the difference between the WSL and the WDSL Combi type?
+
The WSL is a dedicated solventless laminating machine, while the WDSL Combi type combines solventless and solvent-based lamination in one machine and can complete a three-layer lamination in a single pass. Choose the WSL for pure solventless production, or the WDSL Combi for maximum structural flexibility.
