Product Overview

Variovac offers two main thermoforming packaging series: Primus and Optimus, covering the needs of both mid-sized production lines and large-scale industrial production. These devices heat and stretch the film to form, fill, and seal the products in a continuous, fully automated, and high-efficiency process. The equipment is widely used in high-capacity production environments requiring diverse packaging formats and strict food safety standards.

- The Primus series is its high-end model, designed for high-load, large-volume, multi-product industrial packaging needs. The equipment is robust, stable, and supports multiple packaging formats, including vacuum, MAP, skin, shrink film, and hot-fill processes. It is ideal for large meat processing plants, central kitchens, and comprehensive food enterprises.

- The Optimus series is a compact design, balancing performance with cost-effectiveness, suitable for medium-sized companies or line upgrades. The equipment supports a variety of packaging forms and is flexible for medium-volume production and product diversity. For companies introducing automated packaging for the first time, Optimus provides a mature, user-friendly thermoforming solution.

Key Features

Both Primus and Optimus use modular structural designs, offering high customization capabilities. Depending on product attributes and preservation needs, the following packaging methods can be configured:

- Vacuum Packaging: Extends product shelf life by vacuum sealing, ideal for meat, sausages, and cheese.

- Modified Atmosphere Packaging (MAP): Maintains product freshness by replacing the air inside the packaging, widely used for fresh meat, seafood, and ready meals.

- Skin Packaging: The product is tightly sealed against the bottom film or tray, enhancing display quality and transport stability, suitable for high-value meat and seafood.

- Shrink Film Packaging: Perfect for irregularly shaped products, providing a tight fit and clean appearance.

- Hot-Fill: Ideal for hot processing and rapid cooling of prepared meals.

All equipment is made of food-grade stainless steel, meeting high hygiene standards, with quick mold change, easy cleaning designs, and options for integrating labeling, printing, and conveyor systems, adaptable to various automation levels and production layouts.
