All we known that, material cost has always been the major concern for factories. Especially in the flexible packaging industry, this problem is prominent. In most cases, film represents 60%–75% of overall raw material costs. However, Mingli's bag-in-box making machines can effectively solve the challenge.
In this article, we will focus on how Mingli's bag-in-box making machines maintain stable production with ultra-thin 0.03mm film, thereby reducing material costs.
To improve sustainability, more and more bag making machines manufacturers are adopting ultra-thin films. A typical example is pure polyethylene film, measuring 0.03 mm (3 mils). Pure PE film inherently possesses soft texture and high extensibility. When thickness is reduced to 0.03 mm, even the slightest instability during high-speed production can cause the stretch or wrinkle, making it difficult to feed stably.
Some traditional, standard bag-in-box making machines still rely on magnetic powder unwind technology in tension control unit. This not only causes slow machine response and unexplained heat buildup, but also leads to the degradation of the magnetic powder over time, which can damage the surface of materials and hinder production stability. Generally, such machines are only capable of standard products above 0.05mm thickness, let alone 0.03mm.
Mingli's bag-in-box machines adopt advanced servo unwinding and ultrasonic sensor tension control. We upgraded the tension sensors to ultrasonic units and replaced magnetic powder brakes with servo motors. Servo motors respond at least ten times faster than magnetic powder systems and eliminate the issue of magnetic powder degradation, enabling high-speed, precision operation. With such machinery, processing 0.03mm pure PE film is a breeze!
Believing that through the above introduction, you may understand the advantages of our bag-in-box making machines. It's true that inevitably, high-end solutions require a higher initial investment. However, in the long run, with our machines’ unparalleled control over materials and stable production systems, companies can achieve much lower operating costs compared to other solutions, ensuring sustained competitiveness in the future.
If you consider production efficiency, material costs, and equipment downtime as the greatest threats to profits, then Mingli's bag-in-box making machines are the ultimate solution.
