This milk tea sealing machine's teeth are made of food-grade stainless steel. They are crafted through single-tooth grinding and water grinding processes, with sharp and smooth cutting edges without burrs. The teeth are evenly and neatly arranged, suitable for 90/95mm paper-plastic cups. It can precisely seal and cut PP films, paper films, etc., without any leakage. It is wear-resistant, rust-proof, and easy to clean. It features a positioning protection design to extend its lifespan. It is compatible with most commercial models such as Meixue Ice City and Yifang, and supports non-standard customization.

Core classification and structure
| Classification dimension | Common types | Structural Characteristics | Applicable scenario |
| Shape | Straight-toothed cutter | The cutting edge is in the form of straight teeth, with a simple structure. | Bag-making machine for cutting, flat film cutting. |
| Round-toothed cutter | Circular toothed blade, suitable for rotational cutting. | High-speed strip cutting, continuous film rolling cutting. | |
| T-shaped / Triangular toothed cutter | Irregular toothed edge, precise local cutting. | Irregular packaging, easy tear opening fabrication. | |
| Frame-shaped toothed cutter | Closed tooth frame structure, laser welded. | Sealing film is cut and sealed in one step. | |
| Structural parameters | Pitch / Tooth Depth | Customizable, suitable for material thickness. | For thick materials, choose a larger pitch to reduce resistance; for thin materials, select a denser pitch to ensure a smooth cutting edge. |
| Size specification | Maximum length: 4000mm, ultra-thin 0.10mm. | Satisfies the installation and cutting requirements of different models. | |
| Retracting cutter slot | Square design enhances fracture resistance. | High-frequency punching and heavy-duty cutting conditions. |
Core performance advantages
Precise cutting: Precision processing combined with image inspection ensures smooth edges without burrs, preventing material tearing. It is suitable for continuous operation on high-speed production lines, ensuring attractive packaging appearance.
High durability: Superior materials and heat treatment processes enhance wear resistance. The Teflon-coated model reduces friction and heat, lowering the frequency of replacement and saving costs.
Flexible compatibility: Supports non-standard customization based on provided drawings and samples. Dimensions, tooth shapes, and edge parameters can be adjusted to fit vacuum packaging machines, sealing machines, bag-making machines, and other equipment.
Safe and hygienic: Some products undergo acid washing treatment with protective films, meeting hygiene standards for food and pharmaceutical industries.
