Back Sealing Strip Packaging Machine (EP180) — Product Introduction
The EP180 Back Sealing Strip Packaging Machine is an automatic vertical form-fill-seal (VFFS) system engineered for high-volume sachet and small pouch production. It combines film forming, metered filling, back sealing, horizontal sealing, and cutting into one continuous workflow, helping manufacturers shorten cycle time while maintaining repeatable package quality. Designed for liquid, powder, and granular products, the EP180 fits diverse packaging lines where hygiene, stability, and consistent output are critical. Its stainless-steel body supports demanding workshop conditions and routine cleaning, while PLC-based control ensures reliable operation during long production runs. With a standard film width capacity up to 180 mm and a supplied set of bag-making specifications, the machine enables fast commissioning and smooth changeovers for daily manufacturing. Output is typically 20–40 bags per minute, depending on product characteristics, filling method, and bag size. For liquid applications, an added 1 mm horizontal leak-proof line strengthens seal integrity to reduce the risk of seepage and returns. The independent cutter assembly supports either straight (flat) cut or serrated cut, with 3 mm cutter spacing to keep separation neat and edges consistent for better shelf presentation.
Product Features
All-in-one automatic forming and packaging: Integrates bag making, filling, sealing, and cutting in a single machine, reducing labor dependency and supporting stable, scalable output.
Adaptable for multiple product types: Handles liquids, powders, and free-flowing particles, making it suitable for multi-SKU facilities and flexible production planning.
Strong, consistent back sealing: Back seal width of 5–10 mm (plain, no pattern) delivers dependable bonding strength and uniform appearance across continuous runs.
Enhanced leak protection for liquids: A dedicated 1 mm horizontal sealing leak-proof line (liquid applications) improves sealing safety where viscosity, oil content, or moisture may challenge sealing reliability.
Clean cutting with format choice: Select flat cut for a simple edge or serrated cut for easy-tear packaging; independent cutter design with 3 mm spacing supports consistent separation and tidy pouch edges.
Accurate printed film registration: Equipped with a JULONG dual-color photoelectric eye for mark tracking, improving repeatability of bag length and alignment on printed films.
Smooth, stable film pulling: Variable-frequency motor crank mechanism with heat-sealed bag pulling helps maintain steady film transport and consistent packaging rhythm.
Hygienic, durable construction: Stainless-steel main structure offers corrosion resistance and supports cleanliness requirements commonly found in food, daily chemical, and related production environments.
Factory-ready configuration: Delivered as a complete automatic unit with a 1-year warranty and customizable machine dimensions to match different workshop layouts and integration needs.

Application Areas
The EP180 is ideal for automated sachet and small pouch packaging across food, daily chemical, and general industrial production lines. In liquid applications, it is commonly used for sauces, condiments, edible oils, beverages, and detergents where seal strength and leak prevention are essential. For powders, it supports seasoning blends, drink mixes, additives, and fine chemical powders requiring stable bag forming and consistent sealing. For particles and granules, it is suitable for snacks, seeds, pellets, and other free-flowing materials that benefit from reliable film tracking and clean cutting. With PLC-controlled stability, precise photoelectric registration for printed films, and flexible sealing/cutting configurations, the EP180 delivers dependable day-to-day performance for manufacturers seeking consistent output and professional pouch presentation.
