Tray Sealers

What is a tray sealer?

A tray sealer, also known as a top sealer, is a tabletop packaging machine that can be used to pack preformed dishes and containers airtight to prevent them from leaking. Tray sealers are useful for catering companies, delivery services, hotels and restaurants, butchers and supermarkets. Thanks to the leak-proof packaging, delivery meals arrive at their destination without spilling. Prepared meals stay fresh in the refrigerator and the shelves look neat and tidy.

How does a tray sealer work?

Before you start you need the following:

1. A mould in the shape and size of the tray you want to seal
2. Heat resistant sealing foil
3. Plastic or cardboard trays

Choose the shape of the tray you want to seal and place the appropriate mould on the machine. Turn on the tray sealer and set the desired temperature. Once it's warmed up, place a food-filled dish (or tray) in the mould. Pull the foil over it and press down the lid of the tray sealer. After a maximum of five seconds, the sealing process is complete and you can open the lid again and take the dish out. Each compartment of the tray or container is now completely leak-proof.

By using a heating plate, the foil is sealed only on the closing edges of the bowls. Thanks to the special sealing mechanism, you can obtain a large sealing pressure with light pressure. This makes the tray sealer fast and easy to operate.

Which foods can benefit from using a tray sealer?

You can seal almost all food and dishes. This allows you to store them more easily. Examples include:

• dairy products
• vegetables and fruit
• raw and cooked meat
• fish and other seafood
• ready-made meal boxes
• rice and dough products

What should you look for when buying a tray sealer?

Maxima has tray sealers in different sizes. You should consider the dimensions of the trays you want to use because not every tray fits in every machine.

It’s also important to always place a tray sealer on a flat and stable surface. Also, do not put the tray sealer close to a heat source such as a stove, oven or heater. For easy operation and sufficient ventilation, it is best to keep at least 10cm free around the device.

Always use the correct moulds as only these will fit perfectly and ensure that your dish can be sealed properly.

It’s important to know that airtight packing with this packaging machine is not the same as vacuum packing. A tray sealer let you seal a bowl or tray with a foil. This prevents leakage and prevents air from getting in from the outside. With vacuum packing, you put food in a plastic bag where the air is sucked out of the bag by a vacuum machine that then immediately seals it airtight. A tray sealer is used in most cases for food that you only want to store or transport for a short time. Vacuum packaging is suitable for long term storage freezing. 

What other equipment is there for packaging?

Packing machines should be a part of every catering business. It is a shame to throw away ingredients and food that you could have kept for a long time.

That's why Maxima has packaging machines in different shapes and sizes. Besides top sealers, there is also a wide choice of vacuum pack machines . You can preserve food for a very long time with these: up to five times longer than with other packaging. With a vacuum pack machine you place the entire bag with food in the chamber of the machine, which you then close with a lid. The package is vacuumed and then sealed shut. Vacuum sealers come in compact tabletop models, floor models that have wheels and even a machine that has a double chamber for large quantities.

A vacuum sealer is a tabletop vacuum machine without a vacuum chamber. You use sealer rolls or vacuum bags that you place on the sealing bar.

Lastly, there is a vacuum machine for liquids. With this handy tabletop model, you can quickly and precisely vacuum pack soups, sauces and other liquids.
