The Fully Automatic Strip Back Sealing Packaging Machine is a space-saving, high-efficiency strip wrapping system designed for continuous, stable production of small sachets and strip packs. Engineered for manufacturers that demand repeatable sealing quality and neat back-seal appearance, it integrates precise temperature control, servo-driven film pulling, and PLC + touch-screen operation to keep every pack uniform in length, tight in sealing, and clean in cutting. Built with food-grade 304 stainless steel for durability and easy sanitation, the machine supports a wide range of products—from free-flowing powders and granules to compatible liquid applications—while offering flexible bag-size adjustment for fast adaptation to different SKUs. With sealing temperature adjustable up to 300°C and output optimized for consistent performance, it is an ideal solution for scalable, professional single-portion packaging lines.
Product Introduction
This machine forms, fills, seals, and cuts strip-style packages using a back-sealing structure that delivers an orderly, premium finish suitable for retail-ready sachets. The Siemens servo motor heat-sealing bag pulling system ensures smooth film feeding and accurate indexing, improving length consistency and reducing film waste caused by slipping or irregular traction. A PLC control core with a touch-screen interface allows operators to set parameters quickly, fine-tune sealing temperature, and monitor running status in real time. Designed for everyday industrial use, its 304 stainless steel construction enhances corrosion resistance and supports hygienic cleaning routines in food, pharmaceutical, and chemical production environments.
Product Features
Stable high-speed production: Designed to run smoothly at 20–50 bags per minute (depending on product and film), maintaining consistent output without compromising seal strength or pack uniformity.
Servo-driven film pulling for precision: Siemens servo heat-sealing pulling delivers accurate bag length control and steady film movement, helping reduce misregistration, improve repeatability, and lower material loss.
Wide product compatibility: Suitable for powders, particles, and liquids (with appropriate dosing configuration), making it practical for multi-product factories and contract packaging operations.
Clean back-seal aesthetics: Back sealing keeps the front panel tidy for branding and printing visibility, while supporting reliable sealing across common paper/plastic laminations within recommended film specs.
Flexible cutting options: Supports flat cut and serrated cut, enabling different opening experiences and matching downstream requirements such as cartoning, bundling, or display packing.
Hygienic, durable build: Food-grade 304 stainless steel improves corrosion resistance and simplifies cleaning, supporting compliance-oriented production areas and long service life.
Fast setup and easy operation: PLC + touch screen simplifies parameter input, temperature adjustment (0–300°C), and operation monitoring, reducing training time and changeover effort.
Adaptable bag sizes: Adjustable forming range supports multiple sachet formats, helping manufacturers handle multi-SKU production schedules with consistent packaging quality.
