TRC300 Mini Premade Pouch Packing Machine — Compact Doypack & Zipper Bag Filler Sealer
The TRC300 is a space-saving automatic premade pouch packing machine engineered for startups, small food factories and co-packers. It fills and seals doypacks, 3-side seal bags, zipper pouches and gusset bags at 6–15 bags/min — with a footprint of just 1750 × 510 mm.
What Is the TRC300 Mini Premade Pouch Packing Machine?
The TRC300 is a compact automatic premade pouch packing machine manufactured by INMAYPACK, a flexible packaging machinery factory founded in 2009 in Shanghai, China, exporting to international markets. It automatically picks, opens, fills and seals pre-made bags — doypacks, stand-up pouches, zipper bags, 3-side seal bags, box bags and gusset bags — for granules, powders, liquids, coffee beans, candy and pet food. Running at 6–15 bags per minute within a 1.75 m × 0.51 m footprint, it is one of the smallest premade bag packing machines available for entry-level automation.

Why the TRC300 Is the Best Mini Premade Bag Packing Machine for Small Producers
Every function is designed around one goal: reliable automatic pouch packing in the smallest possible footprint, with the lowest possible maintenance cost.
Safety Key Interlock Switch
The machine stops immediately when the safety key interlock is pulled out — protecting operators during bag changeover and cleaning.
No-Bag Prompt Function
Automatic alert when the bag magazine runs empty, so operators refill in time and production never runs blind.
Open-Bag Self-Diagnosis
If a pouch fails to open, the machine skips filling and sealing and re-takes the bag — the pouch is reusable, so zero film waste.
Anti-Drop Hopper Positioning
Positioning function locks the hopper securely in place, preventing product spillage and misalignment during operation.
Heater & Cylinder Fault Warnings
Built-in warning functions for cartridge heater faults and cylinder faults enable fast troubleshooting and less downtime.
Multi-Bag-Type Flexibility
Runs doypack, zipper, 3-side seal, box and gusset bags on one machine — bag changeover is quick and tool-simple.
Modular Low-Cost Maintenance
Parts are replaced module-by-module, keeping maintenance cost low and eliminating long service interventions.
Ultra-Compact 0.51 m Frame
At just 1750 × 510 mm, the TRC300 fits through standard doors and into workshops where full-size rotary machines cannot.
Applications & Optional Filling Devices
Pair the TRC300 with the right dosing system and it becomes a complete small pouch packing line for food and non-food products.

TRC300 Mini Premade Pouch Packing Machine — FAQ
The TRC300 runs 3-side seal bags, stand-up pouches (doypacks), zipper bags, box bags and gusset bags. Bag width ranges from 90 mm to 300 mm and bag length from 100 mm to 300 mm; the TRC-430 version extends bag length up to 430 mm. Changeover between bag types is quick and requires no special tooling.
The TRC300 packs 6–15 bags per minute, which equals roughly 3,000–7,000 pouches per 8-hour shift. Combined with its compact 1750 × 510 mm footprint and low maintenance cost, it is specifically designed for startups, small food factories, co-packers and pilot production lines that are automating for the first time.
Yes. The base machine handles granules such as coffee beans, candy and pet food. Adding a liquid pump filler enables sauces, oils and liquid detergents; adding an auger feeder enables coffee powder, spices, protein powder and flour. Multi-head and linear weighers are available for high-accuracy granule dosing.
The TRC300 has an open-bag self-diagnosis function. If a pouch fails to open, the machine will not fill or seal it — it automatically re-takes the bag, and the unopened pouch can be reused. This prevents product waste and keeps reject rates near zero.

A rotary premade pouch machine like the INMAYPACK ZP-8R200 uses an 8-station rotary layout for higher speeds and larger production volumes, while the TRC300 uses a compact linear layout optimized for minimal floor space and lower investment. Choose the TRC300 for 6–15 bags/min entry-level automation; upgrade to a rotary machine when output requirements grow.
