The Double Vibration Disc Multi-Grain Back Seal Packaging Machine is a compact vertical form-fill-seal (VFFS) solution designed for fast, stable, and accurate counting-and-packing of small pieces and multi-grain products. Equipped with a dual vibrating disc measuring system and a back-seal bag-making structure, it delivers consistent pouch appearance, reliable sealing strength, and efficient output for everyday production. The machine supports composite packaging films (e.g., BOPP/PE) and uses intelligent PLC control with a 7-inch color touch screen to simplify operation, reduce downtime, and improve overall packaging quality.
Product Advantages
Dual vibrating disc counting for higher throughput: The 300-type double vibration disc measuring device supports wide counting ranges and stable feeding, helping maintain speed while keeping counts consistent.
Back-seal pouch structure with reinforced heat sealing: The upgraded heat-sealing mechanism produces clear seal lines and strong sealing performance, supporting improved package integrity and shelf presentation.
Precision bag pulling with stepper motor: Stepper-driven film pulling ensures controlled pouch length, stable registration, and repeatable bag forming for consistent output.
Intelligent control and easy operation: A 7-inch color touch screen with PLC control offers English/Chinese operation, alarm prompts, fault self-diagnosis, and dual PID temperature control for stable sealing temperature management.
Stable feeding and anti-empty-run protection: Linear vibration feeding improves flow stability, while the no-material stop induction device reduces waste and prevents empty or partial packs.
Practical production features: Sawtooth cutting (middle out knife) supports clean separation, and an added exhaust pinhole function helps reduce trapped air for neater, tighter packs.
Flexible configuration for counting and fixed-length control: The 1–16 fixed-length counting feeding device (fixed-length control) supports repeatable dosing patterns for standardized packaging requirements.

Application Areas
This machine is suitable for automated counting and bagging of small-piece or granular products that require stable feeding and consistent pouch sealing, including multi-grain mixes, small pellets, tablets, plastic round sheets, and similar uniform items. It is widely applicable in food packaging, daily-use consumer goods, light industrial parts packing, and other production environments that benefit from back-seal pouches, reliable heat sealing, and efficient high-frequency operation.
