Product Introduction
The Strip Back Sealing Packaging Machine is an industrial automatic solution designed for strip-bag packaging where stable throughput, neat back seals, and repeatable dimensional control are critical. Built on a rigid metal frame and governed by a PLC control platform, it delivers consistent forming, sealing, and cutting performance for strip-format products in continuous production. The machine is compatible with widely used flexible films such as PVC, PE, and PP, allowing manufacturers to select materials based on cost, barrier needs, and package strength. With a customizable overall footprint to match different workshop layouts and line docking requirements, it integrates efficiently into modern packaging systems that demand dependable operation, simplified parameter adjustment, and uniform finished-bag appearance.
Product Features
Clean and Consistent Back Sealing
The back-sealing structure is engineered to produce a straight, uniform seal line that supports strong package integrity and professional presentation. This sealing approach helps improve resistance to handling stress during stacking, conveying, warehousing, and transportation, while maintaining stable performance across supported film types and thickness ranges.
Stable Output for Continuous Production
With an operating speed of 20–50 bags per minute, the system supports mid-to-high volume packaging demands without sacrificing sealing quality. The adjustable speed range enables users to balance productivity with film behavior, product characteristics, and downstream processes such as labeling, cartoning, or boxing.
PLC-Controlled Operation with High Repeatability
A PLC control system ensures consistent cycle timing and reliable process stability, improving repeatability between shifts and operators. Parameter setting and process control are simplified, helping reduce manual intervention and minimizing variability caused by frequent adjustments during long production runs.
High Packaging Accuracy and Neat Bag Presentation
Packaging accuracy up to ±1 mm supports precise cutting and consistent bag length control. This improves overall product appearance, reduces rework caused by misalignment, and lowers film waste associated with irregular lengths or unstable feeding.
Broad Film Compatibility and Practical Thickness Range
Designed for common flexible packaging materials including PVC, PE, and PP, the machine fits standard procurement channels and typical packaging specifications. It supports film thickness from 0.04 to 0.08 mm, providing flexibility for different barrier requirements, stiffness preferences, and seal-strength targets.
Heavy-Duty Construction for Long-Term Reliability
The robust metal structure and approximate 500 kg net weight enhance operational stability by reducing vibration and improving mechanical rigidity. This heavy-duty build supports long service life in demanding factory environments, contributing to consistent sealing performance and dependable daily uptime.
