The vertical form-fill-seal machine forms, fills, and seals bags in a single pass—at up to 80 cycles per minute with a filling accuracy of ±1 g. This guide walks you through the machine's design, filling process, selection, and operation.
Chips, peanuts, and pretzel sticks break on any sharp edge—yet the multi-head weigher still measures them accurately at up to 80 weighings per minute. This article explains what number of weighing heads and what product guidance are needed for snacks.
Powder does not flow; it creates dust and segregates—screw feeders dose it into the bag with an accuracy of ±0.5 %. The article explains the differences between volumetric and gravimetric dosing, as well as venting and hygiene requirements.
Granules are the ideal application for vertical packaging: they flow freely, are easy to dose, and can be packaged at up to 80 cycles per minute using a multihead weigher. This article explains which product parameters determine the line’s performance and where abrasive products pose limitations.
Roasted coffee requires a production line that handles the beans gently and preserves their aroma: gentle feeding, a multi-head weigher, and a seal with less than 2 % residual oxygen. This article describes the system’s design, operating data, and selection criteria.
Every format change brings the line to a halt: 20 to 45 minutes on the VFFS line, 10 to 30 minutes on the pre-made bag line. This article highlights format components, the process flow, and the five factors that influence changeover time.
VFFS or pre-made pouches? This comparison highlights the cycle rate, film costs per pouch, pouch appearance, and format change times for both approaches—along with a five-question decision-making framework to help you plan your production line.
The pouch packaging machine picks up pre-formed pouches, opens them, fills them, and seals them—at a rate of 30 to 60 pouches per minute. It produces high-quality retail formats ranging from stand-up pouches to pour-spout pouches. Design, key performance indicators, and limitations.
The multi-head weigher doses chunky products using a combinatorial approach: Multiple heads determine partial weights, and the control system selects the best combination—±0.3 to 1 g at up to 80 weighings per minute. An overview of the design, number of heads, and applications.
The vertical form-fill-seal (VFFS) machine forms, fills, and seals bags from a roll of film in a single pass—typically at a rate of 40 to 80 cycles per minute. This article explains the machine's design, filling systems, and operational limits.
