Biodegradable Plates
Food Trays with Compartments
Fast-Food Containers
Catering Food Packaging
Ready-Meal Containers

Customized thermoforming molds enable production of various product shapes, sizes, and compartment configurations.

Suitable Materials for Biodegradable Food Containers

PLA - Polylactic Acid

PLA is a bio-based material commonly used in biodegradable or compostable food packaging. It can be thermoformed into containers, trays, bowls, and other packaging products with appropriate sheet formulation and processing conditions.

Starch-Based Materials

Starch-based or starch-filled sheet materials are suitable for certain environmentally friendly food packaging applications. Processing parameters are adjusted according to specific material formulations.

PP - Polypropylene

PP is widely used for food containers and takeaway packaging due to its toughness, heat resistance, and chemical resistance. The machine can be configured for bio-based or starch-filled PP formulations.

PET - Polyethylene Terephthalate

PET is commonly used for food trays and transparent packaging applications. Material selection should align with product requirements and environmental claims.

Other Thermoforming Sheets

The machine can be configured for other suitable thin-wall thermoforming materials based on product requirements and production processes.

How the Thermoforming Machine Works

1. Automatic Sheet Feeding

Plastic or biodegradable sheets are automatically fed into the machine with precise positioning for accurate heating and forming.

2. Sheet Heating

Sheets pass through the heating section and reach optimal forming temperature. Heating parameters are adjustable based on material type, sheet thickness, product shape, forming depth, and production speed. Precise temperature control is crucial for PLA and other temperature-sensitive biodegradable sheets.

3. Positive & Negative Pressure Forming

After heating, sheets enter the forming station where combined positive air pressure and vacuum pressure ensure close conformity to the mold. This is particularly effective for food containers with multiple compartments, deep forming areas, sharp corners, detailed edges, complex structures, and sealing rims.

4. Cutting

Formed containers are separated from the surrounding sheet using customized cutting molds designed according to product shape and cavity layout.

5. Automatic Stacking

Finished food containers are automatically stacked for convenient collection, packing, and subsequent production processes, reducing manual handling and improving production consistency.

Benefits of Positive & Negative Pressure Forming

This advanced forming method ensures precise forming around product edges and corners, particularly beneficial for containers with:

Multiple compartments
Deep cavities
Narrow corners
Detailed surfaces
Complex edges
Sealing or closing areas

Main Features
