In today’s fast-paced packaging industry, stick pack machines have become indispensable for producing single-serve, portable packaging solutions. These machines are highly valued for their efficiency, compact footprint, and ability to handle a variety of products, from powders to liquids. As a leading stick pack machine manufacturer, HIJPACK Machine specializes in automatic stick pack machines that streamline production for industries like food, pharmaceuticals, and cosmetics. This article explores the working mechanism of stick pack packaging machines, their benefits, and why HIJPACK Machine is your go-to solution for coffee stick pack machines and more.
A stick pack machine is a type of vertical form-fill-seal (VFFS) equipment designed to create slim, elongated pouches known as stick packs. These pouches are ideal for single-serve products like instant coffee, sugar, spices, and pharmaceutical powders. HIJPACK Machine offers a range of stick pack filling machines that automate the process of forming, filling, and sealing stick packs, ensuring high throughput and precision. Capable of producing up to 600 stick packs per minute, our stick packaging machines are engineered for reliability and versatility, catering to diverse production needs.
The operation of a stick pack machine involves a seamless, automated process that transforms a roll of film into finished stick packs. Below, we outline the key steps, highlighting the advanced features of HIJPACK Machine’s stick pack packaging machines.
The process begins with a roll of flexible film, known as rollstock, typically made of aluminum/plastic or paper/plastic composites. The film is unwound from a reel at the rear of the stick pack filling machine. HIJPACK Machine’s equipment uses precision servo motors to ensure smooth film transport, maintaining consistent tension to prevent misalignment. An automatic film tracking sensor keeps the film centered, enhancing accuracy during high-speed production.
For branding and compliance, HIJPACK Machine’s stick pack machines can integrate date-coding or batch-number printing systems. The film passes over a registration roller, where a sensor detects printed eye marks to align the design with the sealing and cutting points. This ensures that logos, expiration dates, or other graphics are precisely positioned on each stick pack, enhancing the professional appearance of products like coffee stick pack packaging.
Maintaining proper film tension is critical for consistent pack formation. HIJPACK Machine’s stick packaging machines feature nip rollers and a dancer arm—a weighted pivot mechanism with rollers—that dynamically adjusts to keep the film taut. This system minimizes film slippage or stretching, ensuring uniform stick packs even at speeds of up to 500 bags per minute for our high-capacity models.
The film is then fed into a slitter assembly, where it is cut into narrow strips corresponding to the number of lanes (3 to 12) on the stick pack machine. HIJPACK Machine uses non-motorized cutting disks that slice the film against a specialized roller, ensuring clean, precise cuts. Each strip forms the basis of an individual stick pack, allowing simultaneous production across multiple lanes for maximum efficiency.
The cut film strips are guided over forming tubes, one per lane, where they are shaped into tubular stick packs. The film folds around the tube’s shoulder, with the edges overlapping to form either a lap seal (flat, material-efficient) or a fin seal (protruding). HIJPACK Machine’s stick pack filling machines offer customizable seal options, including three-side, four-side, or back sealing, to meet specific packaging requirements for products like instant coffee or spices.
Once formed, the stick packs are filled and sealed in a synchronized process. Vertical sealer bars, heated to the optimal temperature, create the longitudinal seal by pressing the overlapping film edges against the forming tube. Simultaneously, a horizontal sealing jaw forms the top seal of one pack and the bottom seal of the next. During this pause, a filling system—such as an auger filler for powders or a liquid pump for sauces—dispenses precise product quantities into each pack. HIJPACK Machine’s coffee stick pack machines use servo-driven auger fillers for non-free-flowing powders like coffee, ensuring accuracy and minimal waste.
After filling and sealing, a knife blade cuts the stick packs at the horizontal seal, or a tear notch is added for easy opening. The finished packs drop into an outfeed chute, which releases them onto a conveyor or into a receptacle at controlled intervals. HIJPACK Machine offers optional individual outfeed chutes for oriented discharge, ideal for integration with downstream equipment like checkweighers or cartoning systems.
