What is 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.

FAQ

Q1: What products can the SZ350 Horizontal Flow Wrapping Machine pack?

The SZ350 can pack non-direct-food-contact products within its size range, including daily-use products, small hardware, accessories, stationery, industrial parts, medical consumables with outer packaging, and other

regularly shaped items suitable for pillow bag packaging.

Q2: Is the SZ350 a food-grade flow wrapping machine?

The SZ350 is not positioned as a direct food-contact food-grade model. If the product is food or hygiene-sensitive, buyers should confirm whether the product already has inner packaging and whether special contact-part or hygiene requirements are needed.

Q3: What is the advantage of bottom film feed?

A bottom film feed structure supports the product from below during feeding and wrapping. It can help improve transfer stability for certain products, especially when the product shape, surface, or feeding condition makes top film feeding less suitable.

Q4: What is the packing speed of the SZ350?

The SZ350 supports 30-120 bags/min, depending on product size, film material, bag length, feeding method, and production requirements.

Q5: What bag size range does the SZ350 support?

The SZ350 supports bag lengths from 100-500 mm and bag widths from 35-140 mm, making it suitable for longer pillow bag packaging applications.

Q6: What product height can the SZ350 handle?

The SZ350 can handle products with a height range of 5-60 mm. For taller or bulkier products, Soontrue engineers may recommend another flow wrapping machine model.

Q7:What information should I provide before requesting a quotation?

Please provide product dimensions, product weight, target packing speed, bag size, film material, product photos or videos, feeding method, and whether the product has any hygiene or contact-part requirements.
