Vertical Flow Wrapper for Gravity-Fed Product Packaging

ECHO Machinery vertical flow wrapper systems are purpose-built for free-flowing and gravity-fed products including snacks, cereals, pulses, frozen vegetables, and hardware components. These machines form a vertical film tube from flat roll stock, fill product through a top-mounted hopper, and seal packages in a continuous vertical motion—ideal for pillow packs, gusseted bags, and quad-seal formats. The vertical design minimizes floor space while achieving speeds of 60–120 packs per minute depending on bag length and fill volume. Equipped with servo-driven film advance, multi-head weigher interface, and automatic film tracking, the vertical flow wrapper delivers consistent fill weights and seal integrity across extended production runs. Stainless steel construction meets food industry hygiene standards, and the open-frame design facilitates rapid cleaning during product changeovers.

Company Advantages

Compact Vertical Footprint

Vertical machine orientation reduces floor space requirements by up to 40% compared to horizontal wrappers of equivalent throughput, maximizing production density in space-constrained facilities.

Integrated Multi-Head Weigher Control

Native communication protocol with major multi-head weigher brands enables synchronized fill-timing that minimizes giveaway and achieves fill accuracy within ±1 gram for granular products.

Rapid Clean-In-Place Design

Open-frame construction with tool-free removal of forming tube, film rollers, and sealing jaws allows complete product-contact surface cleaning in under 30 minutes for allergen changeovers.

Vertical flow wrapping represents the most space-efficient approach for packaging free-flowing products, and ECHO Machinery has refined this technology through decades of field experience across food, pet food, and industrial sectors. The forming tube—available in diameters from 50mm to 250mm—creates the film tube through a precision-machined collar that minimizes friction and film distortion. Product drops through the tube into the partially formed bag, with an automatic film advance system that precisely controls bag length through encoder feedback. The sealing system incorporates cross-seal jaws with serrated profiles for easy-open features and longitudinal sealing bars with independent temperature control for the overlap seam. For products requiring gas flushing, a nitrogen injection lance positioned inside the forming tube reduces residual oxygen to extend shelf life. Optional features include hole-punch units for hang-hole bags, tear-notch devices, and inkjet printer integration for date and batch coding.

Frequently Asked Questions

What products are suitable for vertical flow wrapping versus horizontal?

Vertical flow wrappers are ideal for free-flowing granulated, powdered, and small-piece products that can be gravity-fed—such as snacks, nuts, dried fruit, cereals, pulses, frozen vegetables, pet food, and hardware items like screws or fasteners. Horizontal wrappers are better for solid, trayed, or arranged products.

How does ECHO ensure accurate fill weights on vertical flow wrappers?

ECHO vertical flow wrappers integrate directly with multi-head combination weighers through high-speed communication protocols. The wrapper signals the weigher when the bag is formed and ready, and the weigher releases the optimal head combination within milliseconds, achieving fill accuracy of ±1 gram for most granular products.

What bag formats can a vertical flow wrapper produce?

Standard formats include pillow pack, gusseted pillow, and quad-seal bags. By changing the forming tube and sealing jaw configuration, the same machine can also produce block-bottom and Doypack-style stand-up pouches. Bag widths range from 50mm to 250mm and lengths from 80mm to 350mm.

Customer Testimonials

David Rosenthal

Space-saving design that delivers

Our facility has limited floor space, and the vertical flow wrapper from ECHO fit perfectly into our existing layout. It runs our mixed nut line at 80 bags per minute with excellent weight consistency. The open-frame design also makes cleaning between nut varieties straightforward.

Klaus Mueller

Integrated seamlessly with our weigher

We connected this vertical wrapper to our existing Ishida weigher and it communicated flawlessly from day one. Fill accuracy improved noticeably compared to our previous wrapper because the timing synchronization is so precise.
