Frequently asked questions about pouch filling
The questions we get from production and engineering teams, answered plainly — from filling technology to support in Brazil and LATAM.
General
What is the difference between a pre-made pouch and VFFS (roll-stock)?
In VFFS, the machine forms the pouch from a film reel on the line itself — great for a single low-cost format at high speed. With pre-made (rotary), the pouch arrives ready from the factory and the machine only opens, fills and seals it: it allows spout, zipper, capping, premium finish and format change in minutes. See the full comparison between the two technologies.
Is a pre-made pouch more expensive than roll-stock?
The unit cost of pre-made packaging is usually higher than reeled film. In return, it removes the investment in forming the pouch on the line, offers premium finish, special formats and fast format change — which usually pays off on premium and multi-SKU lines.
Machines
How many pouches per minute does a Leepack rotary machine run?
It depends on the series and pouch size: from 20–40 BPM (RG and RV) to 140–160 BPM (RQ, Quadplex). The best-selling RT runs 40–60 BPM and the Duplex RD 80–100 BPM. There is a per-model specification table on the machines page.
How long does a format change take?
On Leepack rotary machines, format change is automatic via HMI, within 5 minutes. That is what makes multi-SKU lines viable without losing productivity.
Which pouch formats do Leepack machines handle?
Stand-up, spout, sachet, stickpack, box pouch and side-gusset (quad-seal) pouch. There is a series dedicated to vacuum (RV) and to center-spout with cap (RS).
Application
Can the same machine fill liquid and powder?
Yes. The rotary machine is product-agnostic: you swap the filler/weigher set according to liquid, paste, granule, powder or solid. The RT, RD, RQ, RG and RV series accept all of these types.
Which machine for a spout pouch with cap?
The RS series (Rotary Filling & Capping) integrates filling and capping for center-spout pouches. For corner-spout, the RT or RD with a spout magazine. Engineering sizes the configuration to your spout and cap.
How do you fill oxygen-sensitive products?
With vacuum filling (RV series, one vacuum chamber per station) or modified atmosphere (N₂ gas flushing). Both extend the shelf life of oxygen-sensitive products.
Support and coverage
Is there technical support in Brazil?
Yes. InovaPouch is the official Leepack Korea representative and provides commissioning, spare parts, training and after-sales directly in Brazil — without depending on support from the other side of the world.
Do you serve outside Brazil?
Yes. Beyond Brazil, we serve several Latin American countries — such as Argentina, Chile, Peru, Colombia, Mexico and Uruguay, among others.
