The Fully Automatic Strip Back Sealing Packaging Machine is a PLC-controlled, high-efficiency packaging solution engineered for continuous forming, dosing (via matched filling systems), sealing, and cutting in one streamlined process. Designed for stable, long-shift operation, it integrates a Siemens servo-driven bag pulling and heat-sealing mechanism to maintain accurate film tracking, consistent bag length, and reliable sealing quality. With a hygienic 304 stainless-steel contact structure and broad material compatibility for paper and plastic films, the machine helps manufacturers achieve clean, professional-looking packs while improving automation, reducing labor dependency, and supporting scalable output for growing production demands.
Product Introduction
Built for modern packaging lines that require speed, repeatability, and dependable sealing performance, this machine produces strip-style packs with a diagonal straight horizontal seal and twisted edge vertical sealing. The sealing system offers a wide working temperature range (0–300℃) to accommodate different film structures within the specified thickness range, while the cutting unit supports both flat cut and serrated cut finishes to match end-user opening preferences and brand presentation. Its compact footprint for its output class and robust mechanical layout make it suitable for factories seeking a balance of productivity, durability, and consistent pack appearance.
Product Features
PLC-Controlled Automation for Repeatable Production
An industrial PLC coordinates film feeding, bag forming, bag pulling, sealing, and cutting into a synchronized workflow. This reduces reliance on manual operation, improves process stability, and helps maintain consistent quality across long production runs. With clear control logic and stable automation, the machine is well suited for standardized packaging requirements and continuous operation environments.
Siemens Servo Bag Pulling for Accurate Length and Registration
The Siemens servo motor heat-sealing bag pulling system delivers precise film movement and consistent bag length control. Accurate pulling improves registration stability, supports neat seal positioning, and reduces film waste caused by slippage or inconsistent tracking—especially important when operating toward the upper end of the output range or when packaging films have different friction characteristics.
Wide Sealing Temperature Range with Clean Seal Performance
With an adjustable sealing temperature range of 0–300℃, the machine can be tuned to match different paper/plastic film constructions and thicknesses (0.04–0.08mm). The diagonal straight horizontal sealing form provides clean, uniform seal lines and a professional finish, while maintaining reliable bonding performance under properly matched temperature, pressure, and dwell time settings.
Two Cutting Styles to Fit Market and Handling Needs
Flat cut and serrated cut options enable flexible pack presentation. Flat cuts provide a crisp, standard edge suitable for industrial packing and bulk distribution, while serrated cuts improve tearability and consumer convenience for retail sachets. This flexibility helps brands align packaging performance with channel requirements without changing the core machine platform.
Hygienic, Durable 304 Stainless-Steel Construction
The 304 stainless-steel contact structure enhances corrosion resistance and supports hygienic production needs. The robust frame and stable mechanical design help the machine maintain performance in demanding plant conditions, while also simplifying routine cleaning and maintenance—an advantage for facilities operating multiple product categories or strict sanitation schedules.
Material Compatibility and Multi-Product Adaptability
Compatible with paper and plastic packaging materials and optimized for film thickness of 0.04–0.08mm, the machine can be configured for powders, granules/particles, and liquid products when paired with suitable dosing and feeding systems. This versatility supports mixed production lines and helps manufacturers standardize equipment across different SKUs and packaging formats.

Application Fields
Food and Beverage Ingredients
Suitable for packing granules and powders such as sugar, salt, seasoning blends, coffee-related ingredients, and similar dry products that require reliable seal integrity, consistent bag length, and clean shelf presentation for retail or foodservice channels.
Daily Chemical and Personal Care
Applicable to detergents, cleaning powders, bath salts, and related products. For compatible liquids, the machine can be integrated with appropriate liquid dosing systems to support stable sealing and consistent pack appearance in daily chemical production environments.
Pharmaceutical and Health-Related Products
Well suited for single-use sachets and small packs of compatible powders and granules where hygienic stainless construction, controlled bag length, and dependable sealing performance are important for standardized packaging and batch-to-batch consistency.
Agricultural and Industrial Consumables
Ideal for small-dose additives, granular consumables, and industrial materials that benefit from fast, repeatable packing cycles. The availability of two cutting styles helps match different downstream handling needs such as manual tearing, automated opening, or secondary packing workflows.
