Core Capabilities of the TL-SP-1L Liquid Stick Packing Machine

( 01 ) Precision Volumetric Filling Across Viscosity Ranges

Fill volume accuracy determines product cost, regulatory compliance, and customer satisfaction. Underfilling triggers consumer complaints and potential legal issues.

Overfilling wastes product and erodes profit margins. The TL-SP-1L achieves fill volume accuracy within ±1% through servo-controlled pump systems with programmable fill profiles.

Operators set target volumes through the touchscreen interface, and the control system adjusts pump parameters automatically for different product viscosities and fill speeds.

( 02 ) Leak-Proof Sealing with Liquid-Contaminated Film Surfaces

Liquid splashing onto seal areas causes seal failures in conventional packaging equipment.

The TL-SP-1L addresses liquid contamination through multiple mechanisms: controlled fill speeds minimizing splashing, nozzle positioning placing liquid below seal zones, extended sealing dwell times allowing heat penetration through contaminated areas, and adjustable sealing pressure ensuring complete film fusion.

Result: consistent seal integrity even when packaging splashy, low-viscosity liquids at production speeds.

( 03 ) Hygienic Design for Food and Pharmaceutical Applications

Liquid products contact filling system components directly, making sanitary design essential for food safety and pharmaceutical compliance.

The TL-SP-1L features stainless steel product contact surfaces, quick-disconnect fittings for cleaning access, and CIP-compatible pump configurations for applications requiring clean-in-place capability.

Tool-free disassembly simplifies daily cleaning routines and product changeovers.

Production Capacity, Installation, and Technical Support

Operating at 60 bags per minute average speed, the TL-SP-1L produces approximately 3,600 liquid stick packs per hour. Single-shift production (8 hours) yields around 28,800 bags, while two-shift operation reaches 57,600 bags daily. Actual throughput depends on liquid viscosity, fill volume, bag dimensions, and cleaning frequency requirements.

High-volume facilities or applications requiring frequent product changeovers may benefit from multiple machine configurations.

Film selection balances barrier requirements, seal performance, and cost considerations. PET/AL/PE laminate provides maximum barrier protection for oxygen-sensitive liquids like juices and pharmaceutical products.

PET/PE structures offer cost-effective performance for general liquid applications. Specialized liquid packaging films featuring enhanced seal strength and puncture resistance suit demanding distribution environments.
Installation requires minimum floor space of 2 × 1.5 meters with operator access and ceiling height of 2.5 meters.

Power supply specifications are 220V single phase, 50-60Hz, 5kW capacity. Liquid filling operations benefit from climate-controlled environments preventing condensation on cold products and maintaining consistent liquid viscosity for temperature-sensitive formulations.

Soontact provides complete support including installation guidance, operator training, and ongoing technical assistance. Spare parts inventory covers wear components and pump rebuild kits. Remote troubleshooting via video call addresses operational issues promptly. Extended warranty and preventive maintenance programs available for facilities requiring additional support coverage.

Liquid Products Packaged with the TL-SP-1L

( 01 ) Food and Beverage Liquids

Juice concentrates and beverage syrups require accurate dosing for proper dilution ratios.

Sauce portions—soy sauce, hot sauce, salad dressing—need leak-proof packaging surviving rough handling in food service distribution. Dairy products including flavored milk, yogurt drinks, and cream portions demand hygienic filling and cold chain compatibility. Honey and syrup portions require heated product handling and high-viscosity pump configurations.

The TL-SP-1L accommodates food industry requirements through sanitary design, accurate volumetric filling, and hermetic sealing protecting product freshness.

( 02 ) Pharmaceutical and Healthcare Liquids

Oral liquid medications require pharmaceutical-grade filling accuracy for proper dosing. Cough syrups, antacid liquids, and nutritional supplements need tamper-evident packaging and batch traceability.

Topical gels and ointments require gentle handling preventing air incorporation. Probiotic liquids demand contamination-free filling preserving live cultures.

The TL-SP-1L meets pharmaceutical packaging standards through stainless steel construction, peristaltic pump options for complete product isolation, and integration with batch coding systems for full traceability.

( 03 ) Chemical and Personal Care Liquids

Detergent portions and cleaning concentrates need chemical-resistant film materials and accurate dosing for proper dilution.

Lubricants and industrial liquids require leak-proof packaging preventing workplace contamination. Shampoo sachets, lotion samples, and serum packets need attractive presentation supporting premium brand positioning.

The TL-SP-1L handles chemical and cosmetic applications through versatile pump configurations, compatible film options, and consistent fill accuracy supporting product performance and brand image.

Frequently Asked Questions About Liquid Stick Packing Machines

( 01 ) What liquid viscosities can the TL-SP-1L handle?

The TL-SP-1L handles liquids ranging from water-thin beverages to thick pastes and gels through interchangeable pump configurations. Gear pumps suit free-flowing liquids with viscosities similar to water, juice, or milk.

Piston pumps handle medium-viscosity products like sauces, creams, and lotions. Peristaltic pumps accommodate thick gels and shear-sensitive products requiring gentle handling. Soontact evaluates specific product samples to recommend optimal pump selection for each application.

( 02 ) How does the machine prevent leaks in filled stick packs?

Leak prevention combines multiple design elements: precision nozzle positioning places liquid below seal zones preventing contamination; controlled fill speeds minimize splashing; anti-drip nozzle designs prevent residual dripping between fill cycles; extended sealing dwell times ensure complete film fusion even with minor liquid contamination; and optimized sealing temperature profiles create strong bonds across various film structures.

Optional seal inspection systems provide additional quality verification for demanding applications.

( 03 ) What cleaning procedures does liquid packaging equipment require?

Liquid filling systems require thorough cleaning between production runs and during product changeovers.

The TL-SP-1L features quick-disconnect fittings for pump and nozzle removal, stainless steel product contact surfaces compatible with standard cleaning chemicals, and accessible design simplifying daily sanitation routines.

Applications with strict hygiene requirements can specify CIP-compatible pump configurations enabling automated clean-in-place cycles without system disassembly.
