5월 18, 2026
In the production of food, 건강 제품, powder and liquid stick packs, poor sealing of the 스틱 팩 포장 기계 is the most common fault, which has troubled numerous production workshops. It often appears as virtual sealing, 열분해, wrinkling and deviation of the sealing edge, further leading to powder leakage and liquid leakage, problems that plague sachet packet and sachet packets production alike.
These problems not only cause a great waste of materials and a large number of finished product scrapping, but also reduce production capacity, fail to meet hygiene standards, and even bring potential safety hazards to product quality, especially critical for products like Pharmaceutical stick pack packaging machines and Food supplement powder stick pack packaging machines. Fortunately, there’s no need to take the machine apart for a full inspection and repair. Starting from the four core parameters of temperature, 압력, speed and sealing wheel gap, this article will teach you how to adjust stick pack machines accurately step by step, so that even novices can get started quickly and solve the problem of poor sealing and material leakage of the 스틱 포장 기계 그리고 향 주머니 포장 기계.
Before adjusting the parameters, we firstly clarify the specific manifestations of poor sealing, so as to accurately judge the problem and find the right direction for parameter adjustment and understand how do stick pack machines work, whether you’re producing Coffee sticks, Instant coffee sticks stick pack packaging machines products, or pharmaceutical sachet packets:
Poor sealing, powder and liquid leakage of stick pack machines are essentially caused by mismatched equipment parameters and production conditions, whether you are using a stick packing machine, sachet packing machine, or specialized models like 4 사이드 씰 향낭 포장 기계.
Main reasons and corresponding adjustment:
Many factors affect the sealing quality of stick packs. 온도, 압력, running speed and sealing wheel gap are the four core parameters. Mastering their correct adjustment methods can solve more than 80% of sealing edge defects, whether you are operating a basic stick pack packaging machine or a specialized sachet packaging machine. The following methods are very practical and can be put into on-site production application, including for stick pack filling machine integrated lines.
Temperature dominates the fusion quality of packaging film. Different film materials have distinct heat resistance, so temperature must be adjusted according to material type instead of random tuning, especially important for Coffee sticks (as in liquid) and Instant coffee sticks (as in powder), which use thin, heat-sensitive films:
Pressure ensures tight lamination after packaging film fusion. Uneven or improper pressure directly leads to local defective sealing, even in advanced stick packaging machine models. The key is to keep pressure balanced and moderate, whether you are producing stick packs or sachet packets:
Running speed is closely tied to heat sealing dwell time. Higher operating speed leads to shorter heat sealing duration, and the worse the film fusion effect. The running speed should be matched according to material characteristics, whether you are using a stick packing machine, sachet packing machine, 또는 4 side seal sachet packaging machines:
The sealing wheel gap and film feeding centering accuracy determine the fitting precision of film edges. Even if temperature and pressure are set normally, deviation in gap or centering will cause edge leakage and film wrinkling, including the operation of a stick pack machine, 향 주머니 포장 기계, or stick pack filling machine:
Different materials vary greatly in fluidity, viscosity and particle size. Which leads to different priorities in parameter adjustment. Targeted tuning can effectively improve sealing yield and reduce material waste, so as to stay competitive in the stick and sachet packing machine market. The key tuning points for common materials are listed as follows:
Powder materials tend to generate dust, and dust adhering to the sealing surface will damage film fusion effect, especially for Instant coffee sticks and Food supplement powder stick pack packaging machines. Key adjustment tips are as follows:
Liquid materials are prone to sealing bulges, and excessive sealing pressure will cause liquid seepage as seen in sachet packet production. Key adjustment points:
Besides parameter adjustment, standardization daily maintenance can greatly lower the failure rate of sealing defects, improve the running stability of the stick pack machine and extend equipment service life, including operations of a stick packaging machine, 향 주머니 포장 기계, or specialized models like Pharmaceutical stick pack packaging machines. This is also a key factor in optimizing performance for the stick packing machine market.
After daily production, promptly clean residual glue, dust and material residue on the sealing wheel surface, to avoid affecting heat conduction and sealing performance, critical for Instant coffee sticks and Food supplement powder stick pack packaging machines where dust is common.
Correct or replace worn or offset sealing wheels in a timely manner to ensure even stress on each seal, so as to obtain consistent quality in stick pack packing and sachet packet production.
Avoid inferior or non-standard film. Films with different heat resistance and thickness will directly mismatch stick pack machine parameters and ruin sealing quality, especially for 2-in-1 instant coffee mix stick pack packaging machines and 3-in-1 instant coffee mix stick pack packaging machines that use specialized films..
When switching packaging film or raw materials, run a trial production of 5f0-100 sticks first. Confirm and optimize parameters before mass production to prevent large-scale product rejection caused by mismatched settings, which is key for reducing waste in stick pack filling machine operations and sachet packaging machine lines.
결론적으로, to solve poor sealing, powder leakage and liquid leakage of the stick pack machine, the core is to accurately control four major parameters: 온도, 압력, running speed and sealing wheel gap, as in basic stick pack packaging machine, 향 주머니 포장 기계, or specialized models like 4 side seal sachet packaging machines or Pharmaceutical stick pack packaging machines.
Recommended debugging priority: adjust temperature first as the most critical factor, then set sealing pressure, optimize production speed, and finally fine-tune the sealing wheel gap and film feeding centering, applicable to all stick pack machines and sachet packing machine models.
This method is simple and easy to operate. No professional maintenance personnel are required; ordinary workshop operators can master independent debugging after proper proficiency, saving costs for business in the stick and sachet packing machine market.
It is worth emphasizing that parameter adjustment is a gradual process, which should be flexibly adapted according to material type (such as Coffee sticks vs. Pharmaceutical sachets), film thickness and production environment as in stick packing machine, stick pack filling machine, or sachet packaging machine.
그 동안에, selecting a stick pack machine suitable for production process, combined with standardized daily maintenance and regular tuning, can not only solve current sealing edge faults, but also stabilize long-term sealing quality, reduce rejection rate, improve production efficiency, and create higher economic benefits for enterprises, when you are producing Instant coffee sticks, sachet packets, or pharmaceutical products. For those wondering How do stick pack machines work, mastering these parameter adjustments is the foundation of efficient, leak-free stick pack packing.
Leakage in stick pack machines is usually caused by incorrect sealing temperature, insufficient sealing pressure, contaminated sealing areas, incompatible packaging films, or improper filling settings. Both powder and liquid products can leak if the seal integrity is compromised during packaging.
Powder stick packs often leak because fine powder particles become trapped in the sealing area, preventing complete heat sealing. Other causes include low sealing temperature, uneven pressure, and poor-quality laminated film. Proper dust extraction and sealing adjustment help reduce leakage.
Liquid sachets are more sensitive to sealing inconsistencies because liquids can easily penetrate weak seal areas. Small fluctuations in sealing temperature or pressure may cause leaks, especially when packaging low-viscosity liquids such as syrups or beverages.
If the sealing temperature is too low, the packaging film layers cannot bond properly. If the temperature is too high, the film may deform or burn. Stable and properly calibrated sealing temperature is critical for maintaining airtight stick pack seals.
Using dust collection systems, optimized filling timing, and anti-static devices can help prevent powder contamination in the sealing zone. Regular cleaning of sealing jaws is also essential to maintain strong seals in powder stick pack packaging.
예. Low-quality or incompatible laminated films may not seal properly under standard machine settings. Film thickness, material composition, and heat-seal coating compatibility all affect sealing performance and leakage resistance.
To fix leaking liquid stick packs, operators should check sealing temperature, 밀봉 압력, pump filling accuracy, and film compatibility. Upgrading to high-barrier films and ensuring proper hot sealing immediately after filling can significantly reduce leakage.
The ideal sealing pressure depends on the packaging material and product type. 일반적으로, the pressure should be evenly distributed across the sealing surface to create a complete and uniform seal without damaging the film.
Sealing jaws, 발열체, and temperature sensors should be inspected and cleaned daily in high-speed production environments. Regular preventive maintenance helps avoid leakage issues, unstable sealing temperatures, and packaging defects.
Pharmaceutical powders, 건강 보조제, instant drink powders, 소스, 시럽, and cosmetic liquids are highly sensitive to leakage because moisture, 산소, or contamination can affect product quality and shelf life.
