FAQ about the Multi-Lane 4-Side Seal Powder Sachet Machine
How many sachets per minute can a multi-lane machine produce?
Each lane runs 25–40 cuts per minute, so output = lanes × speed. A 4-lane FL-M500 makes about 100–160 sachets/min; a 10-lane FL-M700 about 250–400; a 16-lane FL-M980 up to about 640 sachets/min, depending on the powder and the fill weight.
Which powders can be dosed accurately?
Free-flowing and non-free-flowing powders such as milk powder, coffee, protein, flour, seasoning and medicinal powder. Auger (screw) dosing is used; a stirrer and screw size are matched to your powder's flowability and fill weight. Send us a sample for a free test.
What is the difference between 4-side seal, 3-side seal and back seal?
4-side seal gives a flat square sachet sealed on all four edges (premium look, common for seasoning and medicine); 3-side seal is similar with one fold edge; back seal (stick pack) has a long vertical seam and is typical for coffee, sugar and supplement sticks.
What film should I use?
Heat-sealable laminated film such as PET/PE, PET/AL/PE, OPP/CPP or paper/PE. Film thickness and the maximum film width depend on the model (500, 700 or 980 mm).
