    Flow Wrapping Machine

    A Flow Wrapping Machine, also called a horizontal flow wrapper or pillow packaging machine, is used to wrap individual products, grouped products, or tray-loaded products with roll film in a continuous horizontal packaging process.


    It is commonly used for bakery products, biscuits, cakes, chocolate, wafers, frozen food, vegetables, instant food, medical supplies, daily-use products, and industrial items. The machine forms film around the product, seals the package lengthwise, and cuts and seals each pack at the end.


    The key point in flow wrapping is not only the wrapper itself. A stable flow wrapping line depends on product feeding, product spacing, product orientation, film selection, sealing quality, and downstream packaging connection. For soft cakes, the infeed must reduce deformation. For roll-shaped products, product orientation and anti-rolling control are important. For tray products, tray height, tray stability, and film width should be confirmed before machine selection.


    Soontrue Group can configure flow wrapping machines with automatic feeding systems, sorting systems, counting and grouping units, deoxidizer feeding, tray loading, checkweighers, metal detectors, cartoning machines, case packers, case sealers, and palletizing systems according to project requirements.


    Before quotation, buyers should provide product photos, product size, product weight, packaging film, target speed, packaging format, product feeding method, upstream production video, and downstream packaging requirements.

    Vertical Packaging Machine

    A Vertical Packaging Machine, also called a VFFS machine or vertical form fill seal machine, is used to form bags from roll film, fill products into the bags, and seal them automatically in a vertical packaging process.
    It is widely used for loose or bulk products such as snacks, granules, powders, frozen food, pet food, seeds, rice, sugar, salt, hardware parts, and small industrial products. Depending on the product, the machine can work with a multihead weigher, linear weigher, auger filler, volumetric cup filler, liquid pump, or customized dosing system.


    The key selection point is not only the bagging machine model. The correct vertical packaging solution depends on product flowability, product weight, target accuracy, dust level, stickiness, fragility, temperature, bag type, sealing condition, and required output.


    For snacks, the line usually focuses on gentle feeding and accurate weighing. For powders, dust control and sealing area cleanliness are important. For frozen food, product surface moisture, temperature, and product flow should be considered. For small hardware, counting, feeding stability, and bag strength may become key points.


    Soontrue Group can configure vertical packaging machines with elevators, feeders, weighers, fillers, checkweighers, metal detectors, cartoning machines, case packers, case sealers, and palletizing systems according to the full packaging line requirement.


    Before quotation, buyers should provide product type, product size, product weight, target pack weight, bag size, bag style, film material, target speed, dosing accuracy requirement, product photos, and factory layout.

    Premade Pouch Packaging Machine

    A Premade Pouch Packaging Machine is used to automatically pick premade pouches, open them, fill products, seal the pouches, and discharge finished packs. It is also called a rotary pouch packing machine or premade bag packing machine.
    It is suitable for products that need higher shelf presentation or pre-made pouch formats, such as snacks, nuts, granules, powders, sauces, liquids, pastes, frozen food, pet food, coffee, seasonings, daily-use products, and prepared food.
    The key point in premade pouch packaging is that the pouch itself is part of the machine performance. Pouch thickness, stiffness, zipper quality, opening quality, seal layer, gusset structure, and pouch supplier consistency can directly affect picking, opening, filling, and sealing stability.
    Compared with vertical packaging, premade pouch packaging usually provides better retail appearance and supports more pouch styles, including stand-up pouches, zipper pouches, flat pouches, three-side-seal pouches, four-side-seal pouches, and gusset pouches. However, it also requires better pouch quality control and sample testing before final configuration.
    Soontrue Group can configure premade pouch packaging machines with multihead weighers, auger fillers, volumetric fillers, liquid fillers, pump filling systems, checkweighers, metal detectors, case packers, and end-of-line equipment according to product and packaging requirements.
    Before quotation, buyers should provide product type, pouch samples, pouch size, pouch style, filling weight, product photos, target speed, filling method, sealing requirement, and factory layout.

    End of Line Packing Series

    The End-of-Line Packing Series refers to the packaging equipment used after primary packaging to prepare finished products for secondary packaging, shipping cases, palletizing, warehouse handling, and distribution.
    This series can include case erectors, case packers, robotic box packing machines, case sealers, labeling machines, checkweighers, palletizing robots, conveyors, and complete end-of-line automation systems.
    End-of-line packaging is different from primary packaging. Primary packaging protects the product or creates the retail pack. End-of-line packaging focuses on grouping finished packs, forming cases, loading products into cases, sealing cases, labeling, palletizing, and preparing goods for shipment.
    The correct end-of-line solution depends on finished pack type, pack size, pack weight, case size, loading pattern, required output, production layout, pallet pattern, and automation level. A soft bag, rigid carton, tray pack, pail, bucket, bottle, or bundle may require different handling and gripping methods.
    Soontrue Group can configure end-of-line systems for food, frozen food, bakery, tissue paper, daily-use products, hardware, chemical products, and other B2B production lines. The system can connect with upstream flow wrapping machines, vertical packaging machines, premade pouch machines, cartoning machines, or complete automatic packaging systems.
    Before quotation, buyers should provide finished pack samples, pack dimensions, pack weight, case size, case material, loading pattern, target speed, palletizing requirement, factory layout, and upstream packaging equipment information.

    Automatic Packaging System

    An Automatic Packaging System is an integrated packaging line that connects product feeding, sorting, counting, weighing, wrapping, bagging, inspection, secondary packaging, case packing, and end-of-line automation according to product and factory requirements.
    Unlike a single packaging machine, an automatic packaging system is designed around the full production process. It may include a flow wrapping machine, vertical packaging machine, premade pouch packaging machine, cartoning machine, case erector, case packer, case sealer, checkweigher, metal detector, labeling machine, palletizing robot, and customized product handling equipment.
    The correct system depends on product type, product condition, pack format, target output, factory layout, upstream production method, downstream packaging requirement, and inspection standard. A cake packaging system, frozen dumpling packaging solution, wafer packaging system, vertical packaging line, and premade pouch line all require different engineering logic.
    For product-specific systems, such as cakes with deoxidizer, Swiss rolls, wafers, sandwich biscuits, or rice rollers, the feeding and sorting method is often the key. For complete packaging solutions, such as VFFS lines, pouch lines, frozen food lines, or end-of-line systems, the main question is how to balance the capacity of each section.
    Soontrue Group can configure automatic packaging systems for food, frozen food, bakery, snacks, tissue products, daily-use products, hardware, and other industrial products. The system can be designed as a primary packaging line, secondary packaging line, or complete production-to-shipment packaging automation solution.
    Before quotation, buyers should provide product photos, product videos, product size, product weight, target packaging format, required speed, upstream process, downstream packaging requirement, factory layout, power supply, and inspection requirement.

  • Random Product Weighing & Packaging Solution

    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.

  • Water Packaging Solution

    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.

  • Milk Packaging Solution

    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.

  • Edible Oil Packaging Solution

    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.

  • Hardware Parts Packaging Solution

    Hardware components such as screws, bolts, nuts, washers, fasteners, and fittings are usually small in size but demanding in packaging accuracy.
    Unlike products packed by volume or liquid filling, hardware parts are often sold according to quantity. A bag containing 100 screws, 50 bolts, or a specific combination of components requires accurate counting before packaging. Manual counting is time-consuming and difficult to maintain when production volume increases or when multiple SKUs need to be handled.
    Soontrue hardware packaging solutions are designed for automatic feeding, counting, weighing, bagging, sealing, cartoning, case packing, and palletizing of industrial components.
    The packaging process can be configured according to part size, shape, weight, surface condition, package quantity, sales channel, and production requirements.
