Tray Sealer Types: Manual & Automatic

 

Tray sealers can be categorized into Manual and Automatic models, each suited for different production needs — from small-scale operations to larger lines handling frozen or microwave-ready meals.

 

 

Manual Tray Sealer: Affordable, Reliable Sealing for Small-Scale Operations

 

Manual tray sealers are an economical tabletop packaging solution that deliver high-quality, leak-proof seals at an affordable price. Operators manually place containers into the sealing molds and push them through the sealing process, giving full control over each tray.

 

While they are slower than automatic models, manual tray sealers are cost-effective, easy to operate, and simple to maintain, making them ideal for small-scale operations or businesses just starting out. This manual operation also keeps investment costs low—up to 50% cheaper than automatic alternatives—while still sealing hundreds of trays per hour and producing professional results.

Automatic Tray Sealer: Efficient, Customizable Packaging for Food Factories

 

Automatic tray sealers are designed for food packaging operations, delivering fast, efficient, and leak-proof seals with minimal operator effort. Operators simply place trays in position, while the machine handles the sealing automatically, ensuring reliable packaging for factory workflows.

 

 

Key Features for Automatic Tray Sealers:

• Interchangeable molds – Quickly change molds for different containers; a single machine can seal trays of different sizes or shapes.
• MAP (Modified Atmosphere Packaging) – Some models can be equipped with MAP systems to extend the shelf life of food products.
• Customizable models – Molds can be tailored to different container sizes and production requirements, supporting single-, double-, or four-tray sealing to meet production needs.

Automatic Tray Sealer Capabilities: MAP & Interchangeable Molds

 

MAP (Modified Atmosphere Packaging) Technology

 

Modified Atmosphere Packaging (MAP) is a food preservation technology that extends product shelf life by replacing the air inside a package with a specific, controlled mixture of gases, typically nitrogen, oxygen, and carbon dioxide.

 

The PH-900 Series uses Modified Atmosphere Packaging (MAP) to extend shelf life, preserve the fresh appearance of food, and significantly reduce waste.

Automatic tray sealers come with interchangeable molds, allowing operators to quickly change molds for trays of different sizes and shapes.
