Semi Automatic Food Tray Sealing Machine

Semi Automatic Food Tray Sealing Machine

HSQY semi automatic food tray sealing machine is a compact heat-sealing system designed for ready meals, takeaway food, meat, seafood, vegetables, fruit, bakery products and other tray-packed foods. Operators manually load pre-filled trays into the mold, while the machine controls film feeding, heat sealing and film cutting.

The HS250T, HS300T and HS280YT models are designed for small and medium food processors, central kitchens, restaurants, catering operations, meal-prep companies and food packaging businesses that need more consistent sealing than a manual tray sealer without investing in a fully automatic production line.

These semi automatic tray sealers can be matched with compatible PP, PET, CPET and aluminum trays using the correct sealing mold and lidding film. Standard sealing performance depends on the complete tray-film combination, sealing temperature, pressure, dwell time and tray flange condition.

What Is a Semi Automatic Tray Sealing Machine?

A semi automatic tray sealing machine combines manual tray handling with automated sealing operations. The operator places a filled tray into the matching mold and starts the cycle, while the machine feeds the lidding film, applies controlled heat and pressure, seals the film to the tray flange and cuts the film around the tray.

This configuration provides a practical step between a basic manual tray sealer and a fully automatic inline tray sealing system. It is particularly suitable when production volume does not yet justify automated tray loading and conveyor integration.

The HS250T, HS300T and HS280YT models listed on this page are primarily positioned for standard tray sealing. Modified atmosphere packaging, vacuum packaging and vacuum skin packaging require dedicated machine configurations and should not be assumed to be included with these standard models.

Semi Automatic Tray Sealing Machine Specifications

HSQY offers three compact models with different maximum film widths and tray dimensions. Select the machine according to the largest tray format and lidding-film width you plan to use.

The listed 480 trays/hour is a reference capacity for one-tray output. Actual production depends on tray loading speed, sealing temperature, dwell time, operator efficiency, film registration, tray dimensions and production conditions.

Which Semi Automatic Tray Sealer Should I Choose?

How the Semi Automatic Tray Sealer Works

1. Load the Filled Food Tray

The operator places a pre-filled tray into the dedicated sealing mold. The tray dimensions, flange design and mold must match correctly.

2. Start the Sealing Cycle

The operator activates the machine after the tray is correctly positioned. The sealing process then proceeds automatically according to the machine settings.

3. Feed the Lidding Film

Roll film is automatically advanced over the tray. The original equipment information references photoelectric and disc sensing for accurate film feeding.

4. Heat Seal the Tray

Heat and pressure activate the lidding-film sealant against the tray flange. Correct sealing temperature and dwell time depend on the tray material and film structure.

5. Cut the Film

The machine cuts the film around the tray according to the mold and cutting configuration, producing a finished sealed package.

6. Remove the Sealed Tray

The operator removes the finished tray, visually checks the seal and loads the next tray for another cycle.

Compatible Food Tray Materials

The machine can be configured for different preformed food trays. The tray material alone does not determine sealing compatibility; the tray sealing surface and the lidding-film sealant layer must be matched.

How to Choose the Correct Lidding Film

A tray sealing machine cannot compensate for an incompatible tray and film combination. Before purchasing the machine or mold, confirm the exact tray material, sealing layer and lidding-film structure.

Important lidding-film parameters include roll width, roll diameter, sealant layer, sealing-temperature window, film thickness, anti-fog requirement, easy-peel or lock-seal behavior and whether the film is printed or unprinted.

For the HS250T, maximum roll width is 245mm; HS300T supports up to 310mm; HS280YT supports up to 250mm. All three models currently list a maximum roll diameter of 180mm.

Standard Tray Sealing vs MAP Tray Sealing

Standard heat sealing and Modified Atmosphere Packaging are different packaging processes. Buyers should select the machine according to the required shelf-life system rather than assuming every tray sealer includes gas flushing.

For applications requiring gas flushing, vacuum replacement or Modified Atmosphere Packaging, see the HSQY            Gas Flush MAP Tray Sealing Machine    .

Custom Tray Sealing Molds

Tray sealing molds are size-specific components. A tray should not be selected only because its dimensions are smaller than the machine's listed maximum dimensions. The actual rim geometry, corner radius, flange width, tray depth and film-cutting profile must match the mold.

HSQY can discuss customized molds for different tray formats. The original machine specification describes a sliding mold design intended to support faster mold changes.

Buyers planning to run multiple tray sizes should provide all tray drawings or physical samples before ordering so that mold quantity, changeover method and future expansion requirements can be evaluated.

Key Features of HSQY Semi Automatic Tray Sealers

Semi Automatic Operation

Manual tray loading is combined with automatic film feeding, sealing and cutting. This reduces investment and machine footprint compared with a fully automatic inline system.

Automatic Film Feeding

The machine uses film-feed control to advance the roll film consistently through the sealing cycle. The existing product information references photoelectric and disc sensors for film positioning.

Custom Mold Options

Dedicated molds can be developed around different tray sizes and flange geometries within the machine's dimensional limits.

Compact Equipment Footprint

Equipment weights range from approximately 29kg to 34kg, making the series suitable for food operations where production space is limited.

Low Rated Power

Current listed power ratings range from 0.6kW to 0.8kW with a 220V / 50Hz supply. Buyers should confirm local voltage and frequency compatibility before purchasing.

Stainless Steel Construction

The existing product description specifies stainless-steel construction to support cleaning, corrosion resistance and use in food-packaging environments.

Applications of Semi Automatic Food Tray Sealing Machines

Ready Meals and Takeaway Food

PP and CPET ready-meal trays can be sealed for central kitchens, restaurant takeaway, catering meals and prepared-food production when paired with the correct lidding film.

Fresh Meat and Poultry

Standard heat sealing can be used for selected meat and poultry packages where the required shelf-life system does not require a dedicated MAP process.

Fish and Seafood

Preformed trays containing fish and seafood can be top sealed using an appropriate tray and film combination. Package integrity and storage conditions should be validated for the actual food product.

Fruit and Vegetables

Selected fresh produce trays can be sealed with appropriate films. Respiring produce may require perforated or specially selected films rather than a standard airtight film.

Bakery and Confectionery

Cakes, pastries, desserts and confectionery products can be sealed in compatible preformed trays for protection, handling and retail presentation.

Frequently Asked Questions About Semi Automatic Tray Sealers

What is a semi automatic tray sealing machine?

A semi automatic tray sealer requires the operator to load and remove trays manually, while film feeding, heat sealing and film cutting are performed automatically by the machine.

How fast is the HSQY semi automatic tray sealer?

HS250T, HS300T and HS280YT currently list a reference output of approximately 480 trays per hour for one-tray output. Actual production depends on operating conditions and operator loading speed.

What is the maximum tray size?

HS250T supports a listed maximum tray size of 200 × 140 × 80mm, HS300T up to 260 × 180 × 100mm, and HS280YT up to 200 × 180 × 80mm for one-tray output.

Can it seal PP food trays?

Yes, when the PP tray has a suitable sealing flange and is paired with a lidding film designed to seal to that PP structure. A matching mold is also required.

Can it seal CPET trays?

CPET trays can be sealed when the machine uses the correct mold and a lidding film compatible with the CPET tray's sealing surface. Final seal performance should be validated for the intended heating and storage conditions.

Can it seal aluminum trays?

The existing product information lists aluminum trays as a supported option. The sealing film or foil, tray rim and sealing parameters must be matched and tested.

Does this machine support MAP?

The HS250T, HS300T and HS280YT specifications on this page do not list a vacuum pump or gas-flushing system. They should therefore be treated primarily as standard tray sealing machines. For MAP packaging, use a dedicated MAP tray sealer with the required gas or vacuum configuration.

What is the difference between tray sealing and MAP?

Standard tray sealing closes the tray with a compatible lidding film. MAP additionally controls or replaces the atmosphere inside the package using selected gases and generally requires barrier packaging materials and dedicated equipment.

Can one machine seal different tray sizes?

Different tray formats can be considered if they fit within the machine limits and dedicated molds are available. Send the tray drawings or physical samples so the mold requirements can be confirmed.

How do I choose between HS250T, HS300T and HS280YT?

Compare your largest tray dimensions and required film width. HS300T supports the largest listed tray and widest film roll, while HS250T and HS280YT provide more compact alternatives for smaller tray formats.

What voltage does the machine require?

The current specification lists 220V / 50Hz for all three models. Buyers in countries using different voltage or frequency standards should confirm electrical compatibility before ordering.

Does the tray sealer work with easy-peel film?

Yes, if the selected easy-peel film is compatible with the tray sealing surface and can operate within the machine's temperature and film-size requirements.
