High-Precision Powder Stick Packing Machine

Introduction: Where Precision Meets Productivity in Modern Manufacturing

In an era where manufacturing efficiency, product integrity, and supply chain agility are paramount, the packaging line serves as the critical central nervous system of any production facility.

For industries dealing with sensitive powders—from life-enhancing nutraceuticals to daily-consumed food and beverages—the choice of packaging technology directly impacts product shelf life, brand reputation, and operational profitability. The fully automatic packaging machine has evolved from a simple bag-sealing unit into a sophisticated supercomputer, orchestrating a symphony of precision mechanics and intelligent controls.

At Coretamp, we engineer these systems not just as machines, but as reliable production partners. Our Single/Double Powder Stick Packing Machine embodies this philosophy, designed to deliver unparalleled accuracy, speed, and adaptability for manufacturers aiming to excel in a competitive landscape. This article provides a comprehensive technical analysis of its operation and value proposition.

Deconstructing the Packaging Process: A Step-by-Step Technical Breakdown

The Coretamp powder stick packing process is a marvel of integrated engineering. We break down the operation into five distinct, seamlessly connected stages.

Stage 1: Film Feeding & Precision Registration

The process begins with the unwinding of the packaging film—typically multi-layered laminates like OPP/PE or BOPP/VMPET/PE. Our machine features an integral film frame with an automatic tension control system, ensuring consistent film feed without stretching or wrinkling.

A critical differentiator is the color sensor system, which captures registration marks (color dots) on the film. This makes every bag’s print pattern become perfectly aligned, safeguarding brand integrity. The system automatically corrects any deviation, a vital feature for high-speed operation.

Stage 2: Bag Formation & Vertical Sealing

A forming collar guides through the film and shapes it into a tube. Our unique 45° vertical sealing device is a Coretamp advantage. This design ensures a stronger, more consistent seal by applying pressure at an optimal angle.

The sealing jaws, equipped with a bus-type temperature control module managed directly from the touchscreen, maintain exact temperatures for perfect seals across various materials, from 0.06 to 0.1 mm in thickness.

Stage 3: High-Accuracy Powder Dosing

This is the heart of the machine, where precision is non-negotiable. Product is fed from a hopper into custom-designed long screws.

These screws are engineered for specific powder characteristics—whether lightweight protein powder or dense pharmaceutical granules—to minimize air inclusion and achieve filling accuracies of ±1-2%. The LC240B model can achieve speeds of 20-80 bags per minute (up to 7200 bags/hour for double-lane configurations), making it one of the fastest powder stick packing machines on the market.

Stage 4: Horizontal Sealing & Cutting

Once dispenses the precise dose, the film tube moves downward. Horizontal jaws perform the top seal of the filled bag and the bottom seal of the next bag simultaneously. The machine offers various cut types—fillet, flat, or serrated—to meet branding and functional needs.

The sealing time and pressure are programmable, ensuring complete closure even for powders prone to leaking, such as fine tea or spice powders.

Stage 5: Final Ejection & Optional Integration

The finished stick packs are neatly cut and ejected. Optionally, they can be conveyed to a downstream system like a cartoner or case packer.

Coretamp machines are designed for Industry 4.0 readiness, with the capability to connect to SCADA and MES systems for real-time production monitoring, OEE calculation, and predictive maintenance alerts.

Uncompromising Quality Standards and Coretamp Differentiators

Our engineering philosophy is built on four pillars that define the Coretamp difference:

• Hygienic Design & Material Integrity: The entire machine is constructed with SUS304 stainless steel, with all product-contact parts made of superior SUS316 stainless steel. This complies with strict GMP standards, making it ideal for pharmaceutical and food production.
• Certified Safety and Reliability: The machine holds EU CE certification, and its electrical components are CUL certified, guaranteeing international safety standards and reducing operational risk for global manufacturers.
• Operational Intelligence and Ease of Use: Featuring a programmable bus system and bus servos, the machine offers faster response and greater accuracy than conventional systems. With 12 operating languages, intuitive fault diagnostics, and self-alert functions for issues like film breakage, we significantly reduce operator training time and downtime.
• Durability and Ease of Maintenance: The anti-fingerprint surface is easy to clean, and the vertical sealer opens from the middle for effortless access and maintenance, ensuring long-term machine viability and reducing the total cost of ownership.

Application-Specific Solutions for Diverse Industries

The versatility of the Coretamp powder stick packing machine makes it a strategic asset across sectors:

• Health Food & Nutraceuticals: For products like protein powder, probiotics, and meal replacement powders, where dosage accuracy and contamination prevention are critical. Our machines ensure every bag contains the exact active amount.
• Pharmaceuticals: Suitable for packaging pharmaceutical granules and powders, with GMP-compliant construction and validation-ready documentation support.
• Food & Beverage: Ideal for instant coffee, milk powder, tea, seasonings, and lotus root powder. The robust sealing system protects against moisture and aroma loss, preserving product freshness.
