Product Description
Product Overview: Premium Trays with Rolled Rims (Curling)
The NTP-CHX Paper Tray Food Packing Box Forming Machine is a specialized automatic solution designed for the high-end food packaging market. Unlike standard carton erectors that simply fold paper, the NTP-CHX features a unique Three-Course Top Curling System. This technology rolls the edge of the square box into a smooth, rigid rim (similar to a paper cup), making it perfect for Sushi Boxes, Salad Trays, and Premium Takeout Bowls that require a tight-fitting lid.
Key Features & Hydraulic Power
- Top Curling Technology: The machine performs a precise curling operation on the tray's edge. This rolled rim not only looks premium but also significantly increases the box's structural rigidity and ensures a secure snap-fit with plastic lids.
- Hydraulic Forming System: Curling a square box requires immense pressure. The NTP-CHX is equipped with a powerful Hydraulic System to provide the necessary molding force, ensuring every tray is formed perfectly without spring-back.
- Servo Drive Precision: Utilizes Servo Drive Technology for paper feeding and positioning. This ensures the paper is aligned accurately before the heavy hydraulic mold comes down, minimizing waste.
- Eco-Friendly & Efficient: Designed to work with PE Coated Paper (250-400g/m²). It automates the entire process: feeding, forming, curling, and outputting, allowing one operator to manage the production line easily.
Ideal Applications
The NTP-CHX is the machine of choice for producing high-value packaging:
- Sushi & Sashimi Boxes: Rectangular trays with rolled edges for a premium look.
- Salad Bowls: Square or rectangular bowls that need to be leak-proof and sturdy.
- Fruit Trays: Strong trays for packaging fresh fruit in supermarkets.

FAQ: Paper Tray Box Forming Machine - NTP-CHX | Square Bowl with Curling
Two main reasons: Strength and Lid Fit. A curled rim makes the box much stronger and rigid than a simple folded edge. More importantly, if you are selling takeaway food (like salad or sushi) that uses a plastic lid, the curled rim provides a lip for the lid to "snap" onto securely, preventing spills.
Because Curling takes time and pressure. Unlike a standard folder-gluer that runs continuously, the NTP-CHX must stop the paper, use hydraulic pressure to press the mold, and perform the curling action. This process produces a much higher quality product, which commands a higher selling price in the market to offset the slower speed.
You need PE Coated Paper (typically 250g to 400g/m²). The PE coating is necessary not just for waterproofing, but because the heat and pressure help the paper "flow" and hold the curled shape without cracking.
