You're producing yogurt cups, and you've probably noticed that a slightly uneven rim can ruin the entire seal. The foil lid doesn't adhere properly, the product leaks, and you end up with rejected cups and unhappy customers. That's where a cup top flatten machine becomes essential. The MG-DTF Cup Top Flatten Machine uses ultrasonic technology to extrude the formed paper cup roll mouth into a straight, flat plane. This creates the perfect surface for aluminum foil lid application, enhancing both sealing performance and product integrity. This article walks through how ultrasonic flattening works, what makes the MG-DTF different from conventional cup forming equipment, and why a flat top is critical for yogurt cup production.
Q: What exactly does a cup top flatten machine do?
A: It takes a formed paper cup with a rolled rim and flattens the top edge into a straight plane. This creates a smooth, even surface that allows aluminum foil lids to seal properly—something a rolled rim simply can't achieve.
Q: What cup sizes can this machine handle?
A: The MG-DTF handles paper cups with a maximum diameter of 120mm. This covers most standard yogurt cup and food service cup sizes.
Traditional paper cups have rolled rims—they're comfortable to drink from and provide some structural rigidity. But that rolled edge is a nightmare for sealing. A foil lid needs a flat, continuous surface to adhere properly. Any curvature, any unevenness, and the seal fails. The cup top flatten machine solves this by taking the formed cup and using ultrasonic energy to reshape the rim into a flat plane. The result is a cup that seals perfectly every time, eliminating leaks and reducing waste.
Ultrasonic technology uses high-frequency vibrations to soften and reshape the paper material at the rim without burning or scorching. The process is precise, clean, and fast—it doesn't compromise the structural integrity of the cup while creating the flat surface needed for reliable sealing.
Aluminum foil lids rely on heat sealing to bond to the cup rim. Any gap, any unevenness, and the seal is compromised. A flat top ensures that the entire sealing surface makes contact with the lid, creating a consistent, leak-proof bond.
The MG-DTF delivers a production capacity of 80-100 cups per minute. That's fast enough to keep pace with most cup forming lines, ensuring that flattening doesn't become a bottleneck in your production flow. At 100 cups per minute, the machine processes over 5,000 cups per hour—enough to support medium to high-volume yogurt cup production.
The MG-DTF is designed to integrate seamlessly with existing cup forming equipment. Its 80-100 pcs/min output aligns with standard paper cup forming speeds, so you don't have to slow down your primary line to accommodate the flattening process.
Unlike manual or mechanical flattening methods that slow down or lose precision at higher speeds, the ultrasonic system maintains consistent quality across the entire speed range. Every cup that comes out of the machine has the same flat, even rim—regardless of how fast the line is running.
The MG-DTF isn't just a standard cup forming machine with a flattening attachment. It's a purpose-built system with several engineering features that set it apart:
The machine uses an ultrasonic device to extrude the formed paper cup roll mouth into a straight plane. This is fundamentally different from mechanical pressing, which can crush or deform the cup structure. Ultrasonic energy softens the material precisely where it needs to be reshaped, leaving the rest of the cup intact.
One outstanding feature is the automatic lubrication system, which ensures that all machine parts work at optimum efficiency for a long time. This reduces wear, extends component life, and minimizes the maintenance burden on your operators.
The machine is equipped with a vacuum generator, which provides much more stable air than conventional cylinders. Not only does this improve operational consistency, but the generator also saves plenty of space compared to traditional pneumatic systems.
The advanced heating technique contributes zero leakage of drink cups produced by this machine. When combined with the flat top created by the ultrasonic system, this ensures that every cup that leaves your line is ready for filling without risk of leaks.

The MG-DTF serves applications where a flat, sealable rim is essential:
This is the primary application for the cup top flatten machine. Yogurt cups require foil lids that seal completely to maintain product freshness and prevent leakage. The machine fills the blank of making yogurt cups in the packaging industry.
Beyond yogurt, the machine is suitable for other dairy and dessert products that use foil-sealed cups—pudding, mousse, custard, and similar products. Any application where a leak-proof seal is critical benefits from a flattened cup rim.
For food service applications where cups are sealed with peelable foil lids, a flat rim is essential for consistent peel force and consumer convenience. The MG-DTF ensures that every cup meets these quality standards.
The MG-DTF is designed for easy maintenance and backed by comprehensive support:
The automatic lubrication system significantly reduces the frequency of manual maintenance. This means less downtime and fewer demands on your maintenance team.
Mingguo offers a one-year warranty on the MG-DTF from the shipment date. The company provides wearing parts at no charge for one year, giving you peace of mind during the critical first year of operation.
Technicians are available to guide installation and adjustment on site. Free training is provided and continues until the operator fully understands the operation and maintenance of the machine.
Q: Does the flattening process damage the cup's structural integrity?
A: No. The ultrasonic process softens and reshapes the rim without crushing or weakening the cup structure. The rest of the cup remains exactly as it was formed.
Q: Can the machine handle different cup grammages and coatings?
A: Yes. The machine can produce cups in a variety of grammages and sizes, including one-sided and double-sided PE lamination. The ultrasonic system adapts to different material characteristics.
Q: How does this machine compare to standard cup forming equipment?
A: Standard cup forming machines produce cups with rolled rims. The MG-DTF adds the flattening step that's essential for foil-sealed cups like yogurt cups. It's not a replacement for a cup former—it's a complementary machine that adds critical capability.
Q: What's the machine's footprint?
A: The MG-DTF measures 1370×1250×1800mm and weighs 650KG. It's a compact machine that fits into most production floor layouts.
A cup top flatten machine that uses ultrasonic technology to create flat, sealable rims is the practical choice for yogurt cup and foil-sealed cup production. The MG-DTF delivers 80-100 cups per minute production speed, maximum cup diameter of 120mm, ultrasonic flattening that creates a perfect sealing surface, automatic lubrication for reduced maintenance, vacuum generator for stable operation, and a compact 1370×1250×1800mm footprint.
Whether you're producing yogurt cups, dairy dessert cups, or any foil-sealed paper cup application, this machine fills a critical gap in the packaging line.
