What Sets the SC-L Series Apart

( 01 ) Precision Liquid Filling Without Drip Contamination

Liquid products present unique packaging challenges. Drips contaminate seal areas and cause failures while viscosity variations between batches throw off fill volumes. The SC-L Series addresses both problems directly with anti-drip nozzle technology that cuts cleanly between doses.

The seal zone stays dry, ensuring consistent closures and eliminating product waste from failed packages. For fill accuracy, choose between piston pumps, gear pumps, or gravity-fed systems depending on your product's viscosity range—thin beverages and thick condiments both meter accurately.

( 02 ) Continuous Bag Forming, Filling, and Sealing

The machine pulls film from roll stock, forms it around filling tubes, seals the longitudinal seam, fills the product, seals the top, cuts between units, and prints batch codes automatically.

Operators load film and product, then monitor while the system handles everything else. Film clamping mechanisms maintain precise tension throughout the forming process, translating to consistent bag dimensions regardless of production speed.

Whether running stick packs at 50 mm length or stretching to the full 180 mm capacity, finished packages maintain professional appearance.

( 03 ) Built for Regulated Industries

Pharmaceutical oral solutions, nutritional supplements, and food-grade sauces all demand hygienic construction. Every product contact surface uses food-grade stainless steel with designs that eliminate crevices where residue accumulates.

Cleaning protocols integrate into production schedules without excessive downtime. The PLC control system with touchscreen interface logs production data automatically, storing batch records, fill counts, and operational parameters for quality control documentation and regulatory compliance.

Why Choose Multi-Lane Over Single-Lane?

Single-lane machines create bottlenecks when demand increases. Adding more single-lane units means multiplying floor space, operators, and maintenance schedules.

A multi-lane system consolidates production into one footprint while multiplying output proportionally. The TL-SP-820L running 12 lanes produces what would otherwise require a dozen separate machines.

Suitable Applications

( 01 ) Food and Beverage

Fruit juices, energy drinks, flavored water, coffee concentrates, soy sauce, vinegar, cooking oils, salad dressings, ketchup, mayonnaise, honey, and syrup portions.

( 02 ) Pharmaceutical and Nutritional

Oral liquid medications, cough syrups, vitamin solutions, collagen drinks, probiotic liquids, herbal extracts, and nutritional supplement shots.

( 03 ) Personal Care and Household

Shampoo sachets, conditioner portions, body lotion samples, facial serums, liquid detergent pods, fabric softener portions, and cleaning solution packets.

Frequently Asked Questions

( 01 ) What is the difference between TL-SP-320L, TL-SP-620L, TL-SP-720L, and TL-SP-820L?

The primary differences lie in film roll capacity and stick width range. The TL-SP-320L handles narrower sticks (17-35 mm) with a maximum 360 mm film roll, suitable for smaller sachets.

The TL-SP-620L expands width capability to 17-65 mm with 650 mm film rolls. The TL-SP-720L and TL-SP-820L accommodate wider sticks (35-70 mm) with 750 mm and 850 mm film rolls respectively, ideal for larger portion packs and bulk applications.

( 02 ) What bag styles can the SC-L Series produce?

The machine forms three-side seal, four-side seal, and back-seal stick configurations. Irregular shapes are possible for brands seeking shelf differentiation.

Switching between styles requires tooling changes rather than different equipment, allowing manufacturers to serve diverse market requirements with a single machine.

( 03 ) How long does changeover take between products?

Changeover time depends on whether the new product requires different bag dimensions or just a product change. Same-size bag changes typically complete within 30-60 minutes including cleaning.

Dimensional changes requiring tooling adjustments may extend to 2-3 hours. Our team can provide specific estimates based on your production schedule requirements.
