Rotary Pre-Made Bag Packing Machine For Liquid – TL-PB-200L/250L

The Soontact Liquid Rotary Pre-Made Bag Packing Machine (TL-PB-200L/250L) delivers automated packaging excellence for liquid products across food & beverage, daily chemical, pharmaceutical, and cosmetic industries.

The eight-station rotary architecture processes bags continuously—picking, opening, positioning, filling, and sealing in one seamless cycle—achieving production speeds up to 55 bags per minute.

Liquid packaging demands precision beyond what dry product machinery can deliver. Drips contaminate seal zones. Foam disrupts fill accuracy. Viscous products resist consistent dosing.

The TL-PB-200L/250L addresses each challenge through purpose-built liquid handling technology, including selectable pump systems (piston, gear, or peristaltic), anti-drip nozzles, and reinforced sealing units engineered specifically for wet environments.

Rotary Pre-Made Bag Packing Machine For Liquid

Key Features and Engineering Advantages

( 01 ) Precision Liquid Dosing and Anti-Drip Technology

Three pump options address the full viscosity range: piston pumps deliver volumetric accuracy for thin liquids like juices and beverages; gear pumps handle medium-viscosity sauces and oils with consistent flow rates; peristaltic pumps protect shear-sensitive formulations like emulsions and cosmetic preparations.

Anti-drip nozzles retract and cut cleanly after each fill cycle, preventing the drips and strings causing seal contamination in conventional liquid fillers. The result: clean bag openings, strong seals, and zero product waste on equipment surfaces.

( 02 ) Heavy-Duty Sealing for Leak-Free Performance

Liquid products stress package seals during handling, shipping, and consumer use. The TL-PB-200L/250L incorporates reinforced heat-sealing units applying extended dwell time and optimized pressure profiles creating seals exceeding burst-test requirements.

Optional double sealing adds a secondary seal band for products transported under challenging conditions. Embossed sealing creates textured seal surfaces improving grip strength and providing tamper-evidence visual cues consumers associate with product integrity.

( 03 ) Intelligent Automation and Hygienic Design

The PLC control system with touchscreen interface simplifies operation through recipe storage, multi-language support, and guided parameter adjustment.

Automatic alarms respond to abnormal conditions; bag-shortage detection stops production before empty cycles waste machine time; self-diagnostic functions identify maintenance needs before failures occur.

Stainless steel construction throughout product contact zones supports sanitary operation, while optional CIP integration enables automated cleaning between production runs—essential for facilities packaging multiple product types or allergen-sensitive formulations.

Choosing Between TL-PB-200L and TL-PB-250L

The TL-PB-200L optimizes production for smaller pouch formats—single-serve beverages, sample sachets, and travel-size personal care products—achieving speeds up to 55 bags per minute for bag widths between 100mm and 200mm.

The TL-PB-250L accommodates larger format packaging up to 260mm wide and 380mm long, ideal for family-size beverage pouches, bulk sauce refills, and economy-size personal care products.

Both models share identical liquid handling capabilities, differing only in bag size range and corresponding speed optimization.

Liquid Packaging TL-PB-200L/250L Applications

( 01 ) Food & Beverage Industry

Beverage producers package fruit juices, flavored drinks, energy shots, and liquid concentrates in stand-up pouches offering lightweight, shatter-proof alternatives to glass bottles.

Sauce manufacturers fill ketchup, mayonnaise, salad dressings, cooking oils, and condiments into squeeze pouches and spout bags enabling controlled dispensing.

Dairy processors package liquid yogurt, cream, and flavored milk in portion-controlled pouches for foodservice and retail distribution.

( 02 ) Daily Chemical & Personal Care

Shampoo, conditioner, body wash, and liquid soap manufacturers increasingly adopt flexible pouch packaging for eco-conscious consumers seeking reduced plastic waste compared to rigid bottles.

The TL-PB-200L/250L handles medium-high viscosity personal care formulations without the shear degradation gear pumps can cause in sensitive formulations.

( 03 ) Pharmaceutical & Cosmetic Applications

Liquid pharmaceutical products require contamination-free packaging under controlled conditions.

The TL-PB-200L/250L supports pharmaceutical applications through sanitary construction, optional nitrogen flushing displacing oxygen, and integration with cleanroom environments.

Frequently Asked Questions

( 01 ) What viscosity range can the TL-PB-200L/250L handle?

The machine accommodates liquids from water-thin beverages (1-10 cP) through medium-high viscosity products like honey, sauces, and hair conditioners (up to approximately 10,000 cP).

Pump selection matches product characteristics: piston pumps for thin liquids, gear pumps for medium viscosity, and peristaltic pumps for shear-sensitive or particulate-containing products.

( 02 ) Can the machine handle hot-fill applications?

Yes, with appropriate configuration. Hot-fill applications require temperature-resistant seals, modified nozzle materials, and adjusted sealing parameters.

Consult Soontact engineers for hot-fill specification requirements.

( 03 ) Is nitrogen flushing available for oxygen-sensitive products?

Yes, optional nitrogen flushing displaces oxygen from the package headspace before sealing, extending shelf life for products susceptible to oxidative degradation.

Nitrogen flushing proves particularly valuable for natural juices, sauces without preservatives, and cosmetic formulations containing active ingredients.
