ZL-300B Vertical Packaging Machine
The ZL-300B Vertical Packaging Machine is a medium-to-large vertical form fill seal machine for automatic bag forming, filling, sealing, and cutting. It is designed for buyers who need a wider packaging range than standard medium VFFS machines but do not yet require a full heavy-duty bulk packaging model.
As part of Soontrue Group's vertical packaging machine series, the ZL-300B can be integrated with different feeding, dosing, and filling systems. Depending on the product, it can work with a multihead weigher, linear weigher, auger filler, volumetric cup filler, or other filling equipment. This makes it suitable for medium-to-large vertical packaging lines where bag size, filling weight, and film compatibility matter.
The ZL-300B supports bag lengths from 80-400 mm, bag widths from 105-280 mm, and packing film widths from 240-600 mm. Its packing speed is 15-55 bags/min. The machine is positioned between standard medium bag machines and larger bulk packaging models, giving buyers more packaging capacity without moving directly into the largest machine platform.
Before requesting a quotation, buyers can prepare product type, target filling weight, bag size, film material, target speed, filling accuracy requirement, product samples or videos, and whether the line requires upstream feeding or downstream packaging.

The ZL-300B supports 15-55 bags/min, making it suitable for medium-to-large vertical packaging where stable filling and larger bag handling are required.
The machine can work with a multihead weigher, linear weigher, auger filler, volumetric cup filler, or other dosing equipment, depending on product characteristics, filling weight, and accuracy requirements.

Liquid seasonings may look similar to other liquid products, but their packaging requirements vary significantly. Low-viscosity products such as soy sauce and vinegar require accurate filling and clean sealing because the liquid flows quickly and can easily reach the sealing area. Other products, such as concentrated seasoning sauces or cooking liquids, may contain oil, spices, suspended particles, or higher viscosity ingredients that affect filling stability.

The solution can cover liquid feeding, metered filling, sachet packaging, pouch packaging, spout pouch filling, inspection, case packing, and palletizing.
Soontrue provides automated shampoo packaging solutions for shampoo, conditioner, body wash, shower gel, hair treatment products, and similar personal care liquids.
These products are usually thicker than water and may behave differently depending on formulation, temperature, fragrance content, and added ingredients. Some flow smoothly, while others stretch, foam, or leave a product tail after filling. A small amount of shampoo around the pouch mouth can also affect sealing quality and create an untidy finished pack.
Soontrue configures shampoo packaging lines around product viscosity, foaming behavior, filling volume, package format, cleaning needs, production speed, and downstream packing requirements. The line can cover product feeding, metered filling, sachet packaging, premade pouch filling, spout pouch packaging, checkweighing, case packing, and palletizing.
Soontrue provides automated detergent liquid packaging solutions for liquid detergent, dishwashing liquid, hand soap, surface cleaner, laundry liquid, disinfectant liquid, and other household chemical liquid products.
Liquid detergents are usually more complex to package than simple water-based products because their viscosity, foaming behavior, chemical composition, and additives can vary significantly. Some products flow easily, while others are thick, create foam, or leave residue after filling. These characteristics directly affect filling accuracy, sealing cleanliness, and finished package appearance.
Soontrue configures detergent liquid packaging lines according to product viscosity, chemical characteristics, filling volume, package format, production speed, cleaning requirements, and downstream packing needs.

Soontrue provides automated water packaging solutions for drinking water, purified water, mineral water, flavored water, and other non-carbonated water products.
Water is easy to pump, but high-speed flexible packaging still requires precise control. Small changes in filling volume, film tracking, bag length, or sealing pressure can lead to uneven packs, weak seals, or leakage. Because water has low viscosity, any delay in nozzle shut-off can also leave liquid near the sealing area.
Soontrue configures water packaging lines around filling volume, package format, film structure, target output, hygiene requirements, and downstream handling. The line can cover water feeding, measured filling, sachet forming, pouch filling, sealing, inspection, case packing, and palletizing.
Soontrue provides automated milk packaging solutions for fresh milk, flavored milk, dairy beverages, milk drinks, and similar liquid dairy products.
Milk packaging places greater demands on hygiene, filling stability, and seal integrity than many general liquid applications. The product can foam during filling, leave residue around the pouch opening, or spoil quickly if the package is not sealed correctly. Cold-filled and heat-treated dairy products may also require different packaging materials and line conditions.
Soontrue configures milk packaging lines around the dairy product, filling temperature, target volume, package format, hygiene requirements, output, and downstream handling. A complete system can cover milk feeding, metered filling, sachet packaging, pouch filling, sealing, checkweighing, case packing, and palletizing.
Soontrue provides automated juice packaging solutions for fruit juice, vegetable juice, mixed juice drinks, juice concentrate, flavored juice beverages, and similar liquid products.
Juice packaging requirements change with the product itself. Clear filtered juice behaves differently from pulpy juice, concentrated juice, or drinks containing fruit fibers. Filling temperature, foam, suspended particles, sugar content, acidity, and package size can all affect filling stability and seal quality.
Soontrue configures juice packaging lines around the actual beverage, filling volume, package format, hygiene requirement, production speed, and downstream packing method. The line can cover liquid feeding, metered filling, sachet packaging, premade pouch filling, spout pouch packaging, checkweighing, case packing, and palletizing.
Soontrue provides automated edible oil packaging solutions for cooking oil, vegetable oil, soybean oil, sunflower oil, corn oil, olive oil, blended oil, and other food-grade oil products.
Oil packaging looks simple, but small details on the line can directly affect finished pack quality. Oil can leave residue near the filling area, weaken the seal if it reaches the sealing surface, and make flexible packs harder to handle after filling. For stand-up pouches or spout pouches, filling stability, pouch opening, sealing accuracy, and finished pouch shape all need to be considered.
Soontrue configures edible oil packaging lines around oil type, filling volume, pouch format, sealing requirement, package strength, production speed, and downstream packing method. A complete line can cover oil feeding, metered filling, sachet packaging, premade pouch filling, spout pouch packaging, checkweighing, case packing, and palletizing.
Soontrue provides automated sauce packaging solutions for ketchup, chili sauce, soy sauce, salad dressing, cooking sauce, dipping sauce, and other liquid or semi-liquid condiments.
Sauce packaging is not only about filling liquid into a bag. Different sauces behave very differently on the line. Thin sauces may drip easily, thick sauces may leave product tails after filling, and chili sauces or dressings with particles may cause unstable filling if the pump and filling path are not selected correctly.
Soontrue configures sauce packaging lines around the actual product condition, package format, filling volume, sealing requirement, and downstream packing method. A complete line can cover sauce feeding, metered filling, sachet packaging, premade pouch filling, spout pouch packaging, checkweighing, cartoning, case packing, and palletizing.
Some products do not need to be arranged in a fixed order before packaging. Snacks, frozen foods, confectionery, small dry products, irregular pieces, and other loose items may enter the packaging process randomly. The package is controlled by target weight rather than by product orientation or an exact visual arrangement.
A random product weighing and packaging solution receives loose products in bulk, distributes them into weighing hoppers, calculates a suitable weight combination, and discharges the selected portion into a bag or pouch.
The product may remain unordered inside the finished package, but the feeding rate, weighing process, discharge timing, bag opening, and sealing cycle must still remain coordinated.
The complete line can include bulk product feeding, elevation, distribution, combination weighing, vertical bagging, inspection, coding, case packing, and palletizing.
