Strip Back Sealing Packaging Machine
The Strip Back Sealing Packaging Machine is an industrial-grade solution developed for forming, filling, and back-sealing strip bags with dependable consistency. Built on a heavy-duty metal frame and driven by a PLC control platform, it delivers stable operation at 20–50 bags per minute while maintaining precise bag-length control within ±1 mm. The machine is designed for continuous production environments where output uniformity, seal integrity, and smooth workflow integration are essential. With broad compatibility across common flexible films such as PVC, PE, and PP, it supports a wide range of strip-bag packaging requirements and helps manufacturers standardize packaging quality across different product lines.
Product Features
Clean and reliable back sealing: The back-seal structure forms neat sealing lines and consistent closure strength, improving package integrity and reducing the chance of leaks, returns, or rework.
High efficiency with controlled accuracy: Designed for 20–50 bags/min and ±1 mm length accuracy, the system helps keep batch-to-batch consistency and supports stable downstream processes such as counting, boxing, or cartoning.
Wide film material compatibility: Supports commonly used films including PVC, PE, and PP (and similar flexible materials), allowing users to choose packaging materials based on barrier needs, cost targets, and product positioning.
PLC-based control for repeatable production: The PLC control system improves operational stability, simplifies parameter setting, and makes it easier to reproduce the same packaging results across shifts and production runs.
Heavy-duty metal construction: A robust metal structure and 500 kg machine body enhance rigidity and long-term reliability, making the unit suitable for continuous industrial use.
Flexible format range: Supports a practical strip-bag size range, with packaging length adjustable from 50–180 mm and width from 50–200 mm, enabling fast changeover for different SKUs and packaging formats.
Optimized for smooth production flow: Engineered to maintain steady feeding, forming, and sealing rhythm, helping deliver stable output for downstream packing lines and improving overall line efficiency.

Application Fields
This strip back sealing packaging machine is ideal for manufacturers and contract packers that require stable, fast, and uniform strip-bag packaging. It supports applications where consistent bag dimensions, smooth sealing quality, and reliable output are needed for efficient handling and secondary packaging.
Food and snack products: Suitable for small-portion or single-serve strip packaging where seal reliability and steady throughput help protect freshness and streamline distribution.
Beverage-related consumables: Applicable to grouped or paired consumables that benefit from compact strip-bag formats and standardized bag sizing for easy packing and storage.
Daily necessities and consumer goods: Works well for lightweight items, accessories, and bundled goods that require clean back seals and consistent strip presentation.
Pharmaceutical and healthcare-related formats (where applicable): Can support strip-style packaging workflows for certain healthcare products, subject to product requirements, compliance validation, and material suitability.
Integration with boxing/cartoning lines: Commonly used as an upstream strip-bagging unit to provide uniform strip packages for downstream carton/box packing, improving line coordination and reducing manual intervention.
