The Multi-Grain Back Seal Packaging Machine is a high-performance vertical form-fill-seal (VFFS) system designed for accurate, stable, and efficient small-dose packaging. Built around the PM180E back-seal main unit with a 304 stainless-steel structure, it is suitable for multi-grain, counting, and general-purpose dosing needs. It delivers consistent bag forming, clean back sealing, and reliable operation for products such as soft capsules, hard capsules, and tablets, making it an ideal choice for manufacturers seeking speed, precision, and hygienic production.
Product Advantages
This machine combines compact design with industrial-grade components to ensure long-term stability and easy operation. A servo-driven cross-seal bag pulling system improves bag length accuracy and enhances sealing consistency at higher speeds. The control system integrates an Inovance PLC with a 7-inch color touch screen, supporting bilingual operation and providing fault prompts with self-diagnosis to reduce downtime. Independent dual-channel Omron PID temperature control manages longitudinal and transverse sealing temperature precisely, helping prevent weak seals, wrinkles, or film burn-through across different composite films. The product-contact sections are made of 304 stainless steel to meet hygiene expectations and simplify cleaning, while Schneider/Omron electrical parts and AIRTAC pneumatic components contribute to dependable performance in continuous production environments.

Application Fields
This back-seal packaging machine is well suited for industries that require efficient single-sachet packaging of small solid products. Typical applications include pharmaceutical and healthcare production lines for capsules and tablets, nutraceutical and supplement sachets, and contract packing operations requiring flexible multi-product capability. It is also applicable to any facility using composite films for back-seal pillow bags where stable sealing, precise dosing, and consistent bag appearance are critical to product presentation and downstream handling.
