Multi-Lane Liquid & Paste Stick Packing Machine

Feature

Engineered for fluid, viscous, and semi-paste formulations, the LTC Multi-Lane Liquid Stick Packing Machine delivers leak-proof, single-serve pouching for liquid food, sports nutrition, and oral care products. Featuring precision rotary/piston pumps with anti-drip cut-off nozzles, it prevents product splashing on the sealing area, ensuring zero leakage and long shelf life.

Working Process 

1. Film Unwinding & Slitting: Master film roll is unwound with constant tension control and precision-slit into multiple strips.

2. Tube Forming: Each film strip is shaped around a stainless steel forming tube.

3. Vertical Sealing: Heated vertical seal bars seal the rear overlap of each stick.

4. Auger Dosing: Servo augers dispense precise powder charges into each formed tube.

5. Horizontal Sealing & Cooling: Cross seal jaws seal top/bottom seams and apply tear notches.

6. Cutting & Discharge: Flying knives or die-cut punches separate sticks onto the discharge conveyor.

Applications 

• Food & Condiments: Pure honey, maple syrup, ketchup, chili sauce, salad dressing, fruit paste.

• Sports & Health Nutrition: Energy gels, liquid collagen, liquid calcium, oral syrup.

• Personal Care & Chemical: Mouthwash sticks, shampoo samples, sanitizing lotions.

FAQ

Q1: How do you prevent sticky sauces or viscous gels from dripping onto the sealing line?

A: The machine is equipped with pneumatic shut-off nozzles featuring an active suction-back (pull-back) mechanism. At the end of each stroke, the valve instantly snips the liquid stream and draws excess product back, leaving the seal zone clean and eliminating post-seal leakage.

Q2: Can the liquid stick packer handle high-viscosity products like honey or peanut butter?

A: Absolutely. For high-viscosity formulations, we configure the machine with a heavy-duty rotary valve piston pump, a jacketed water-heating hopper with temperature control, and a low-speed anchor stirrer to keep the product at a steady, pumpable viscosity.

Q3: How is the liquid contact path cleaned and sanitized (CIP)?

A: All fluid contact parts are made of sanitary SUS316L stainless steel with food-grade Teflon/silicone hoses. The system features standard sanitary Tri-Clamp fittings and includes a automated Clean-in-Place (CIP) flushing cycle program accessible directly through the PLC touchscreen.

Q4: Can I pack products containing small soft particulates (e.g., chili sauce or fruit pulp)?

A: Yes. We offer modified wide-passage rotary valve pumps and widened filling nozzles capable of handling small, suspended particulates (generally up to 2–3 mm) without clogging the pump chambers.

Q5: Is it possible to produce special stick shapes, like bottle shapes or tear notches?

A: Yes. In addition to standard straight and zig-zag cuts, we can install custom die-cut punching stations to produce bottle-shaped spouts, easy-pour micro-tips, and rounded corners for convenient on-the-go consumption.

Q6: Does the machine protect sensitive liquids (e.g., oral supplements, oils) from oxidation?

A: Yes. We offer an optional multi-lane nitrogen flushing system (gas flushing) that displaces residual oxygen inside the pouch prior to sealing, significantly extending product freshness and shelf life.
