ZONESUN | SEALING & PACKAGING SOLUTIONS

Tray Sealing Machines

Seal preformed trays with compatible lidding materials for prepared meals, food portions and other tray-packed products. Match your ZONESUN tray sealing setup to the tray shape, rim material, product conditions and required output, with tooling and workflow options assessed for your application.

Tray Size & Tooling

Match tray dimensions, rim shape and compartment layout to suitable support and sealing tools.

Film & Seal Compatibility

Confirm the lidding material, sealing layer and required seal strength or peelability.

Operation & Output

Assess tray loading, film handling and sealing cycles around your target production rate.

Packaging Workflow

Plan connections with product dosing, coding and downstream packing where required.

CHOOSE YOUR PACKAGING PROCESS

Find the Right Tray Packaging Configuration

Start with the finished pack you need, then match the equipment and materials.

Lidding-Film Tray Sealing

Apply compatible lidding material to the rim of a preformed tray. Confirm tooling, film feeding and the required sealing conditions.

Vacuum Skin Packaging

Assess dedicated equipment that draws compatible skin film around the product. Confirm tray suitability, product height and the vacuum process.

Cling-Film Tray Wrapping

Wrap film around a loaded tray for the specified presentation. This process differs from sealing a lidding film to the tray rim.

These processes use different equipment and packaging materials. Thermoforming equipment forms packs from film and should be assessed separately from preformed-tray sealing.

TRAYS & PRODUCT APPLICATIONS

Match Tray Packaging to Your Product

Provide actual product, tray and film samples to assess the proposed configuration.

Ready Meals & Portions

Share tray compartments, fill level and product temperature. Review lid clearance and cleanliness of the sealing rim.

Meat & Seafood

Specify product shape, moisture and the desired pack format. Assess lidding or skin packaging with suitable samples.

Fruit & Vegetables

Provide product size, tray rigidity and presentation requirements. Select wrapping or sealing around the intended handling conditions.

Deli Foods & Cheese

Share portion size, product height and tray format. Review film compatibility and the required opening characteristics.

Sauces & Prepared Foods

Describe viscosity, particulates and filling temperature. Assess dosing and measures to keep the sealing area clean.

Specialty & Multi-Compartment Trays

Provide drawings, rim geometry and compartment details. Confirm tray support, tooling and changeover for each format.

Pack suitability and shelf life depend on the product, packaging materials, process and storage conditions. Confirm vacuum or gas-flushing functions separately.

FROM FILLED TRAY TO FINISHED PACK

How Lidding-Film Tray Sealing Works

A typical preformed-tray sealing workflow coordinates tray support, film presentation and sealing.

  1. 01

    Load & Position

    Place the filled tray in suitable tooling and keep the rim clear of product.

  2. 02

    Present the Film

    Position compatible lidding film over the tray with registration where specified.

  3. 03

    Seal & Cut

    Apply the configured sealing cycle and trim film where the machine supports it.

  4. 04

    Check & Discharge

    Check film placement and seal condition before downstream handling.

Vacuum skin packaging and cling-film wrapping follow different processes. Filling, vacuum, gas flushing, coding and inspection are configuration-dependent.

KEY SELECTION POINTS

What to Confirm Before Choosing a Tray Sealer

These six details help define material compatibility, tooling and practical output.

Tray Material & Dimensions

Provide material, length, width, depth, rim dimensions and compartment layout. Include drawings and representative trays.

Film & Sealing Layer

Share film structure, sealing layer and thickness. For rolls, specify film width, roll diameter and core size.

Product & Fill Conditions

Describe portion weight, temperature, moisture and product height. Identify splashing or contamination near the rim.

Finished-Pack Requirements

Specify lidding, skin packaging or wrapping, seal strength and peelability. Confirm vacuum or atmosphere requirements if needed.

Output & Format Changes

State trays per minute or hour, loading method and SKU changes. Assess cycle time together with operator handling.

Tooling, Utilities & Layout

Confirm tooling for every tray format, available space, power and air requirements. Allow access for cleaning and film changes.

AUTOMATION & CUSTOMIZED SOLUTIONS

Integrate Tray Sealing into Your Packaging Workflow

Coordinate product supply, tray handling and downstream packing around your process.

Product Preparation & Supply

Define product transfer and any mixing or temperature-control needs before dosing or tray loading.

Tray Feeding & Support

Assess tray separation, loading and positioning. Confirm automatic feeding separately for the proposed machine.

Filling & Rim Cleanliness

Match dosing or portion loading to the product. Review fill level and protection of the sealing area.

Film Handling & Sealing

Coordinate film feed, tooling and sealing conditions. Specify printed-film registration or vacuum functions where required.

Coding & Inspection

Specify date and batch codes and required quality checks. Confirm separate inspection or rejection equipment.

Discharge & Case Packing

Plan transfer of finished trays, grouping and case packing. Match conveyor height and handling to pack stability.

TRAY SEALING FAQ

Frequently Asked Questions

Answers about tray materials, packaging processes and automation.

Are tray sealing and cling-film wrapping the same?
No. Lidding-film sealing bonds compatible film to the tray rim. Cling-film wrapping places film around the tray. Choose the process based on the finished pack and handling requirements.
Does every tray sealer provide vacuum or gas flushing?
No. Vacuum, skin packaging and gas flushing require suitable equipment and controls. Specify the required process and confirm the functions included in the selected configuration.
Can one machine handle different tray sizes?
Different tray dimensions, rim shapes or compartments may need separate support tooling, sealing tools and cutting parts. Confirm the supported range and changeover for each format.
How do I choose compatible trays and lidding film?
Match the tray rim material with the film sealing layer and supported process. Supply actual trays and film for assessment rather than relying only on material names.
Does a tray sealer also fill the trays?
Standalone sealers generally receive trays that have already been filled. Product dosing, portion loading and automatic tray feeding must be specified separately.
Will sealing extend my product shelf life?
Shelf life cannot be determined from the sealer alone. It depends on the product, hygiene, packaging barrier properties, process and storage conditions, and requires suitable validation.
What information should I send for selection?
Send tray and film samples, material specifications, product details, fill conditions, desired pack format, target output, SKU changes and available line space.
