FAQ about the VFFS Packing Machine 420–900
Which frame size should I choose?
Choose by bag width: the film width ≈ (bag width + 10 mm) × 2. For a 200 mm wide bag you need ~420 mm film, so the FL-V420 or FL-V520. Larger 5–25 kg bags need the FL-V730 or FL-V900.
Linear weigher or multihead weigher?
Linear weighers are economical for free-flowing, uniform granules (sugar, rice, beans) at moderate speed. Multihead weighers are faster and better for irregular products like chips and candy.
