¿Cómo construir una línea de producción completa de bandejas de vino?
As the global ban on plastics tightens, the wine industry is rapidly shifting towards molded fiber packaging. Paper wine trays are eco-friendly, protective, and—when made correctly—look incredibly premium.
However, producing high-end wine trays is different from making simple egg cartons. It requires a sophisticated wine tray production line that includes specialized steps like hot pressing and edge trimming to achieve a smooth, burr-free finish.
Are you planning to set up a factory? In this guide, we walk you through the complete workflow of an industrial molded pulp wine tray machine line, converting waste paper into profit.
Sistema de pulpa
The quality of the tray starts with the pulp. You cannot just mix paper and water randomly.
- Hydraulic pulper: waste paper (newspapers, cardboard, offcuts) is thrown into the pulper, where it is broken down into fibers.
- Refining and consistency control: the pulp is refined and adjusted to a specific concentration. For wine trays, the fiber consistency must be precise to ensure strength and shock absorption.
Forming System
This is the core of the wine tray production line.
- Vacuum absorption: the forming molds are dipped into the pulp slurry. A powerful vacuum pump sucks the fibers onto the mesh mold, creating the wet shape of the wine tray.
- Transfer: the wet tray (containing about 70% water) is transferred to the transfer mold.
- Key Tech: our industrial molded fiber packaging machines enable deep-cavity molding, ideal for securely holding 750ml wine bottles.
Sistema de secado
The wet trays are too fragile to be pressed immediately. They must pass through a Multi-Layer Metal Drying Line.
- Proceso: the trays travel through a tunnel heated by gas, diesel, or electricity.
- Result: the moisture evaporates, and the tray hardens. However, at this stage, the surface is still rough and “woolly,” similar to an egg carton. This is not enough for premium wine packaging.
Hot Pressing System
This is the secret to high-quality wine trays. To make the surface smooth and the dimensions precise, the dried trays go into a Paper pulp hot pressing machine.
High temperature and pressure: the machine uses heated molds (around 150°C-200°C) and hydraulic pressure (10-20 tons) to compress the tray.
The transformation:
- Smoothening: the rough fibers are ironed out, creating a sleek, smooth surface.
- Densification: the tray becomes thinner but much stronger and more rigid.
- Stackability: hot-pressed trays stack perfectly, saving shipping space.
Packaging and Sterilization
The final step in the wine tray production line is quality control and packing.
- UV sterilization: some lines include a UV light station to ensure the packaging is food-safe.
- Stacking: automated stackers count and pile the trays, ready for shipment to vineyards.
