SZ350 Horizontal Flow Wrapping Machine
The SZ350 Horizontal Flow Wrapping Machine is a bottom film feed rotary flow wrapper for automatic pillow bag packaging. It is designed for products that are better supported from the film side during feeding and wrapping, especially non-direct-food-contact items, daily-use products, small hardware, accessories, and similar regularly shaped products.
As part of Soontrue Group's flow wrapping machine series, the SZ350 uses a bottom film feeding structure to support stable product transfer before sealing. This makes it different from top film feed models and helps reduce product shifting during the wrapping process when the product shape or feeding condition requires better film support from below.
The SZ350 supports bag lengths from 100-500 mm, bag widths from 35-140 mm, and product heights from 5-60 mm. Its packing speed range is 30-120 bags/min, making it suitable for steady pillow bag packaging where product handling, bag length flexibility, and stable rotary sealing are more important than ultra-high-speed output.
This model is not positioned as a direct food-contact food-grade machine. For food products or hygiene-sensitive applications, buyers should confirm whether the product is directly exposed, whether inner packaging already exists, and what material/contact-part requirements are needed before selecting the final configuration.

The SZ-350 supports 30-120 bags/min, making it suitable for stable continuous packaging of non-direct-food-contact products, daily-use goods, accessories, and industrial items.
The rotary motion end sealing system provides continuous sealing and cutting for pillow bag packaging, helping maintain smooth operation and consistent bag appearance.
The SZ-350 supports bag lengths from 100-500 mm and bag widths from 35-140 mm, giving buyers flexibility for longer products or products that require extended pillow bag length.
With a machine weight of about 260 kg and overall dimensions of 3550 × 880 × 1100 mm, the SZ-350 offers a compact but stable structure for daily production environments.
The servo control system improves film feeding accuracy, sealing synchronization, and cutting stability, helping reduce film waste and maintain consistent pillow bag quality.
The SZ350 can be used as a standalone bottom film feed flow wrapping machine or integrated into automatic packaging solutions based on the production process.
It can support packaging applications for daily-use products, small hardware, accessories, stationery, industrial parts, medical consumables with outer packaging, and other non-direct-food-contact products within the machine's size range. Depending on the production line, Soontrue Group can provide supporting options such as automatic feeding, sorting, counting, labeling, cartoning, case packing, or other secondary packaging equipment.
For products with special hygiene requirements, buyers should confirm whether the item is directly exposed or already protected by inner packaging before selecting this model.

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.
Soontrue provides automated packaging solutions for daily necessities including tissues, wet wipes, disposable products, household items, and other consumer goods.
Daily necessity products usually involve high-volume production, multiple package sizes, and frequent distribution requirements. Compared with products that are simply filled into containers, many household goods require careful arrangement, counting, grouping, wrapping, and secondary packaging to achieve consistent retail presentation.
Products such as tissues, wipes, disposable tableware, and household consumables may vary significantly in shape, softness, compression ability, and packaging requirements. Some products need gentle handling to maintain appearance, while others require high-speed grouping and case packing for large-scale distribution.
Soontrue configures daily necessities packaging solutions according to product structure, production speed, package format, retail requirements, and logistics needs.

Soontrue provides automated electronic components packaging solutions for connectors, terminals, sensors, switches, small electrical parts, and electronic accessories.
Electronic components usually have strict requirements for quantity accuracy, product protection, and packaging consistency. Compared with general industrial parts, many electronic components are smaller, more precise, and more sensitive to handling conditions.
The packaging process needs to consider factors such as component size, surface protection, static sensitivity, quantity control, and customer supply requirements. Small connectors and terminals are often supplied in fixed quantities, while electronic accessories may require organized packaging for assembly or distribution.
Soontrue configures electronic components packaging solutions according to component characteristics, packaging specifications, production volume, and downstream requirements. The solution can include automatic feeding, sorting, counting, weighing, bagging, pouch packaging, cartoning, case packing, and palletizing.
Soontrue provides automated packaging solutions for disposable products including disposable tableware, food containers, gloves, hygiene products, hotel supplies, and other single-use products.
Disposable products are usually manufactured in large quantities and require efficient counting, stacking, grouping, and packaging before distribution. Compared with traditional consumer goods, many disposable items have irregular shapes, lightweight structures, or flexible materials, making stable product handling an important part of the packaging process.
Products such as disposable cups, plates, cutlery, gloves, and containers often need automatic arrangement and quantity control before entering the final package. For high-volume production, manual counting and packing can become inefficient and difficult to maintain consistent quality.
Soontrue configures disposable products packaging solutions according to product shape, material, package quantity, production speed, and logistics requirements. The solution can include automatic feeding, stacking, counting, wrapping, bagging, cartoning, case packing, and palletizing.
Products with a regular shape are not always ready to enter a secondary packaging machine directly.
Biscuits, bakery products, frozen foods, tissue packs, disposable tableware, soap bars, trays, and other individual items may first need to be counted, aligned, turned, stacked, or grouped into a defined arrangement. If this preparation is performed manually, packaging speed and pack consistency often depend heavily on the operator.
An orderly product collation and secondary packaging solution automates the transition from individual products to a stable multipack.
Products are received from the upstream production or primary packaging line, arranged according to the required quantity and orientation, and transferred into a flow wrapper, bagging machine, cartoner, or other secondary packaging equipment.
The final system is configured according to product shape, incoming arrangement, stacking stability, quantity per pack, required packaging format, target output, and available factory space.
Soontrue provides automated tissue paper packaging solutions for facial tissue, toilet paper, paper towels, napkins, and other household paper products.
Tissue products are lightweight but require highly organized packaging processes. Unlike rigid products, paper products can be compressed, folded, stacked, or easily deformed if handled incorrectly. Stable product arrangement and controlled packaging pressure are important to maintain package appearance and consumer experience.
Modern tissue production often involves high-speed converting and packaging operations. After folding, cutting, or stacking, products need to be grouped, wrapped, bagged, cartoned, or packed into cases according to different market requirements.
Soontrue configures tissue paper packaging solutions according to product type, package format, production speed, and distribution requirements. The solution can include product feeding, stacking, counting, compression, wrapping, bagging, cartoning, case packing, and palletizing.
