Shaped Bag Vertical Form-Fill-Seal Packaging Machine KL-300

Keypack Intelligent Shaped Bag Vertical Form-Fill-Seal Packaging Machine KL-300 — Special-Shaped Pouch Filling for Food, Pharma & Chemical

Keypack Intelligent KL-300 is a shaped bag vertical form-fill-seal (VFFS) packaging machine engineered for precise metering and automated pouch packaging of liquid, paste, powder, and granule materials in special-shaped pouches. It delivers ≤±1% weighing accuracy at 20–40 bags/min with a full SUS304 stainless steel body and PLC servo drive control, meeting food-grade, pharmaceutical GMP, and chemical production standards. Ideal for condiment sauce sachets, herbal beverage pouches, mouthwash single-dose packs, milk powder sachets, and seasoning powder special-shaped bags.

Product Overview

The KL-300 is a multi-material, multi-format vertical packaging machine built around the capability to produce special-shaped pouches — including stand-up pouches, waist-shaped bags, heart-shaped bags, and custom contour formats — that standard VFFS machines cannot achieve. This makes the KL-300 a premium choice for brands that need distinctive, shelf-ready packaging to differentiate their products in competitive retail and e-commerce markets.

Beyond shaped bag capability, the KL-300 handles the full spectrum of material types: liquid (sauces, beverages, oral liquids), paste (condiment paste, cosmetic gel), powder (milk powder, spice powder, pharmaceutical powder), and granules (seasoning granules, herbal granules). The machine automatically completes metering, bag forming, filling, gas flushing or evacuation, date printing, and counting in a single continuous cycle.

At its control core, the KL-300 uses a PLC servo drive system paired with an oversized color touchscreen HMI. Multi-product packaging recipes are stored on the touchscreen and recalled instantly when switching between SKUs — eliminating re-setup time and reducing changeover downtime. The full SUS304 stainless steel frame is dust-proof, corrosion-resistant, and easy to sanitize, making it suitable for GMP-regulated food and pharmaceutical environments.

Keypack Intelligent (kunbupack) KL-300 shaped bag VFFS machine can be paired with matched liquid pump fillers, screw metering feeders, or weighing systems to form a fully automated special-shaped pouch packaging line tailored to your material and output requirements.

Machine Specifications

Key Features and Machine Characteristics

• Special-Shaped Pouch Forming Capability — The defining advantage of the KL-300 is its ability to produce special-shaped bags — non-rectangular, contoured pouches that create strong visual differentiation on shelf. Stand-up pouches, waist-shaped sachets, and custom-profile bags are achievable without switching to a separate machine, giving brand owners maximum packaging flexibility.
• Multi-Material Compatibility: Liquid, Paste, Powder & Granules — Unlike single-material filling machines, the KL-300 is configurable for liquid (sauces, beverages, oral liquids), paste (condiment paste, gel), powder (milk powder, spice powder, pharmaceutical powder), and granule materials by pairing with the appropriate metering module — making it a versatile, future-proof investment for multi-SKU production lines.
• PLC Servo Drive System with Large Touchscreen HMI — The servo-driven control core maximizes machine precision and repeatability across all bag formats and material types. The oversized touchscreen provides intuitive operation, real-time monitoring, and fault diagnostics, reducing operator training time.
• Multi-Product Recipe Storage — Packaging parameters for multiple products and bag formats are stored on the touchscreen and recalled instantly when switching products, eliminating re-calibration downtime and supporting rapid changeover between shaped bag SKUs.
• Full SUS304 Stainless Steel Body — Dust-Proof & GMP-Compliant — The all-stainless construction is corrosion-resistant, dust-proof, and easy to sanitize, meeting food-grade and pharmaceutical GMP hygiene requirements. Stable and durable for long-term continuous production.
• Safety Guards & Compliance — Equipped with safety protection covers that meet enterprise safety management standards, reducing operator risk on the production floor.
• Automated Full-Process Packaging — Automatically completes metering, shaped bag forming, filling, gas flushing/evacuation, date printing, and counting in one continuous cycle, minimizing labor and maximizing throughput.
• Color Mark Detection + Ribbon Coding — Standard color mark sensor ensures precise film registration for printed and shaped packaging films; standard ribbon coder prints production dates, batch numbers, and expiry dates on each pouch.
