What is a Chub Packaging Machine & How Does It Revolutionize Viscous Packaging?
A chub packaging machine is a continuous, high-speed automated system designed to form flat rollstock film into a continuous tubular cylinder, inject a precise volume of high-viscosity paste, slurry, or ground product, and securely seal both ends using either synchronized metal clipping, ultrasonic welding, or continuous thermal fusion. By combining the lowest cost-per-package packaging materials with extreme hermetic barrier protection, chub packaging drastically lowers operational overhead while extending product shelf life.
Continuous Rollstock Formation
Converts cost-effective flexible rollstock films (PVDC, laminated PE, nylon barrier films) into an air-free continuous tubular sheath around a specialized stainless steel forming mandrel.
Positive Displacement Extrusion
Integrated with rotary vane, continuous auger, or twin-screw positive displacement metering pumps that transport chunk, paste, or emulsified mixtures without cell damage or entrapped oxygen pockets.
Dual-End Hermetic Closure
Simultaneously gathers the casing neck, applies dual aluminum wire clips, and severs between clips with razor-sharp pneumatic or servo knives to output tightly filled, consistent chub logs.
Primary Processing Applications for Chub Packaging Systems
From refrigerated proteins to construction-grade chemical mastics, chub packaging machinery replaces heavy rigid canisters, metal cans, and thermoformed trays with ultra-compact, hermetic rollstock film tubes.
Ground Beef, Poultry, Pork & Sausage Chubs
Fresh ground beef, pork sausage, taco meat fillings, and turkey chubs benefit from complete zero-oxygen enclosure. High-barrier barrier films prevent lipid oxidation, preserve natural meat coloration, and allow flash freezing or water-bath post-pasteurization.
- Portion range from 250g retail tubes to 10kg commercial batches
- Strict 3-A Sanitary / USDA-compliant food grade 316 stainless steel
- Thermal longitudinal seal with wire-clipped or ultrasonic sealed ends
Raw Pet Food, Fresh Canine Rolls & Meat Paste
The surging global market for fresh raw-meat canine diets and semi-moist feline paste relies on chub packaging machines to provide convenient slice-and-serve portioning, superior freezer preservation, and high consumer retail appeal.
- High viscosity bone-inclusive or pureed raw meat formulation handling
- Tear-resistant heavy gauge barrier film handling up to 120 microns
- Rapid recipe changeover between different protein formulations
Silicone Caulk, Polyurethane Sealants & Adhesives
Chub packaging replaces rigid plastic cartridges with aluminum-foil or polymer “sausage” foil packs. This reduces packaging material waste by over 95% while fitting standard reusable manual and pneumatic applicator guns.
- Compatible with high moisture-curing polyurethane and MS polymers
- Explosion-proof (ATEX / C1D1) pneumatic options available
- High-barrier aluminum foil laminates prevent premature curing
Processed Cheese, Butter, Cookie Dough & Masa
Hot-fill and warm-fill applications such as pumpable cheddar cheese spreads, bulk butter logs, and refrigerated pre-portioned cookie doughs utilize airtight chub systems to maintain strict microbial control without requiring chemical preservatives.
- Hot-fill capabilities up to 90°C (194°F) with jacketed cooling tunnels
- Integrated inline metal detection and dynamic weight inspection
- Easy slicing convenience for downstream catering & consumer use
State-of-the-Art Technical Capabilities & Control Systems
Modern high-speed chub packaging requires millisecond precision to coordinate film unwinding, volumetric product dosing, air evacuation, voiding/casing gathered pinching, and dual wire clipping without bursting the casing wall.
Synchronized Servo-Driven Voiding & Clipping
Advanced pneumatic/servo voiding jaws dynamically displace product away from the seal zone prior to clipping, eliminating seal contamination and guaranteeing 100% leak-proof hermetic integrity.
Continuous Thermal & Ultrasonic Longitudinal Seam
Selectable sealing modules support heat sealing, high-frequency RF, or ultrasonic welding to form seamless longitudinal tubing from single-layer or multi-layer barrier laminates at speeds exceeding 30 meters/min.
Smart Industry 4.0 PLC & AI Recipe Management
Siemens or Allen-Bradley touchscreen HMI storing over 100 automated product programs with real-time film tension adjustment, CIP (Clean-in-Place) automation, and remote diagnostic telemetry.
Integrated De-Aeration & Vacuum Compaction
Continuous vacuum assist channels evacuate air from the feed line to eliminate pinholes and product oxidation, maximizing post-packaging density and clean aesthetic presentation.

Why Switch to Chub Packaging? Key Operational & Cost Advantages
Replacing pre-formed plastic trays, rigid cans, or cartridges with continuous form-fill-seal chub packaging provides immediate material savings, streamlined logistics, and improved environmental sustainability.
Packaging Material Cost
Rollstock casing films cost a fraction of thermoformed trays or blow-molded plastic bottles, dramatically slashing total consumable expense per unit.
Shelf Life Longevity
Airtight vacuum-extruded chub formation eliminates headspace oxygen, preventing aerobic bacterial proliferation and lipid discoloration.
Storage & Freight Space
Unprinted and printed film rolls occupy minimal warehouse space compared to truckloads of empty rigid plastic tubs or cardboard boxes.
Product Evacuation
Flexible chub skins allow end consumers or industrial operators to squeeze out practically 100% of product, eliminating formula waste.

How to Select & Configure the Ideal Chub Packaging Machine
Achieving flawless chub packaging performance requires matching your formula’s viscosity, temperature requirements, and barrier needs with the right pump mechanism and closure technology.
1. Evaluate Viscosity & Flow
Identify if your product behaves as a Newtonian liquid, high-thixotropic paste (silicone caulk), or fibrous aggregate (ground beef). This determines whether an auger screw, rotary vane pump, or piston feeder is required.
2. Select Film & Seal Type
High-barrier PVDC or aluminum laminates dictate continuous thermal vs. ultrasonic seam welding. Ensure the selected film thickness (50μm – 150μm) provides appropriate oxygen transmission rate (OTR) protection.
3. Choose Closure Mechanism
Aluminum wire clip closures are the standard for heavy meat chubs and silicone sausages. For clean-peel or clip-free designs, evaluate our heat-sealed flat-end ultrasonic closure systems.
4. Define Thermal Operating Window
Hot-filled cheese sauces (85°C) require jacketed hoppers and water-bath chillers, whereas cold-extruded ground meat (0°C to 4°C) demands insulated food-grade contact parts to prevent lipid melting.
5. Integrate Inline Inspection
Equip the discharge conveyor with dual-frequency metal detectors (capable of detecting ferrous particles within aluminum clipped chubs) and dynamic high-speed checkweighers with pneumatic rejectors.
6. Plan Downstream Automation
Coordinate seamless transfer from the chub packaging machine into automated tray loaders, rotary clipping collectors, or robotic cartoning lines to eliminate manual labor bottlenecks.
Frequently Asked Questions: Chub Packaging Machines
Find expert engineering answers to common inquiries regarding rollstock materials, filling accuracy, sanitization protocols, and line changeovers.
What films and barrier laminates can run on a Ludyway chub machine?
Our equipment is engineered to process virtually all flexible packaging films, including multi-layer co-extruded PVDC, polyethylene (PE), metallized PET laminates, nylon barrier films, and aluminum foil structures ranging from 45 microns to 150 microns in thickness.
How does the machine avoid product contamination in the clip or seal area?
Ludyway machines feature synchronized mechanical “voiding jaws” (pinch rollers) that squeeze and clear the product from the specific section of the tubular casing where the dual clips or ultrasonic seals are applied. This guarantees a clean, hermetic seal free of entrapped meat or paste particles.
What is the typical time required for diameter and recipe changeover?
Thanks to our modular quick-release forming mandrels and toolless casing guides, complete mechanical diameter changeovers can be achieved in under 20 minutes. Recipe adjustments (weight, length, speed) are selected instantaneously on the touchscreen HMI.
How is the machine sanitized and cleaned in meat and dairy plants?
Our food and pet food chub machines are fabricated with continuous washdown 304/316 stainless steel, IP69K electrical components, and smooth sloped surfaces to prevent water pooling. Contact parts and extrusion pipes feature quick-disconnect sanitary tri-clamp fittings for rapid CIP/SIP cleaning.
