Plastic fruit trays are widely used for strawberries, blueberries, grapes, cherries and other fresh produce. Thermoforming is an efficient production method for manufacturing thin-wall plastic trays in different shapes and sizes.
A Fruit Tray Thermoforming Machine can heat plastic sheets, form them with customized molds, cut the finished products and stack the trays automatically.
The suitable material depends on the final packaging requirements.
Common thermoforming materials include:
PP
PET
PS
PLA
Other suitable thermoforming sheets
PET is often considered when transparency and product visibility are important.
PP can be considered for applications requiring good toughness and different temperature-performance requirements.
The correct material should be selected according to the fruit packaging application, sheet specifications and local regulations.
The basic production process is:
Plastic Sheet Feeding → Heating → Forming → Cutting → Stacking
Each step affects the quality and productivity of the final fruit tray.
The thermoforming sheet is fed into the machine automatically.
The sheet thickness and width should match the selected machine and mold configuration.
The feeding system needs to maintain stable sheet positioning during production to achieve consistent forming and cutting.
The plastic sheet is heated to a suitable forming temperature.
Heating needs to be controlled according to:
Material type
Sheet thickness
Product depth
Mold design
Production speed
Proper heating helps the sheet form evenly around the mold.
After heating, the sheet moves into the forming station.
The customized fruit tray mold determines the final product shape.
Depending on the machine configuration and product design, positive pressure, negative pressure or positive and negative pressure can be used.
For trays with detailed structures or deeper forming requirements, the forming method should be selected according to the actual product design.
After forming, the individual fruit trays need to be separated from the surrounding sheet.
Automatic cutting can be integrated into the production process depending on the machine model.
The cutting layout should be designed together with the mold and product arrangement to reduce material waste and achieve stable production.
After cutting, the finished fruit trays can be automatically stacked.
Automatic stacking is especially useful for high-volume production because it reduces manual product collection and keeps the finished products organized.
A thermoforming machine can be used to produce different fruit packaging designs.
Examples include:
Strawberry trays
Blueberry trays
Grape trays
Cherry trays
Mixed fruit trays
Fresh produce trays
Supermarket fruit trays
Customized fruit containers
The exact product shape depends on the mold design.
The mold needs to match the final fruit packaging requirements.
Important parameters include:
Tray dimensions
Tray depth
Number of cavities
Fruit size
Product arrangement
Material
Sheet thickness
Cutting layout
Stacking method
A product sample, drawing or detailed dimensions can help the machine manufacturer evaluate the mold design.
Before purchasing a machine, buyers should confirm several important parameters.
The tray length, width and depth determine the required forming area and mold size.
PP, PET, PS and other materials have different forming characteristics.
Sheet thickness affects heating requirements, forming performance and machine configuration.
The required output should be considered before selecting the machine model.
For high-volume production, automatic forming, cutting and stacking can reduce manual operations.
The number of cavities directly affects the number of products produced during each cycle.
Thermoforming is suitable for producing thin-wall plastic packaging in different shapes.
For fruit packaging manufacturers, the main advantages can include:
Customized product shapes
High production automation
Multiple-cavity production
Suitable for PP and PET applications
Automatic cutting options
Automatic stacking options
Flexible mold design
Suitable for different fresh produce packaging
The actual production efficiency depends on material, sheet thickness, product design, mold configuration and machine model.
When comparing suppliers, buyers should look beyond the machine price.
Important factors include:
Machine configuration
Forming method
Heating system
Automation level
Mold quality
Cutting system
Stacking system
Installation support
Spare parts
After-sales service
