250mm Tray Sealing Film Specifications

The following specifications describe the standard product range. Final technical parameters should be confirmed according to the selected film grade, tray structure, sealing equipment and packed food.

Easy-Peel, Strong-Seal and Anti-Fog Options

Easy-Peel CPET Lidding Film

Easy-peel film is designed to give consumers a controlled and convenient opening experience. The required peel force should be matched to the tray flange, packed food, tray size, distribution conditions and heating method.

Strong-Seal Lidding Film

A stronger seal may be selected for liquid-rich foods, sauces, institutional meals, demanding transportation conditions or applications requiring increased package integrity. Seal strength must be balanced with the required opening method.

Anti-Fog Lidding Film

Optional anti-fog treatment helps reduce condensation that may obscure the packaged food. It is especially useful for chilled prepared foods, refrigerated retail meals and products where clear presentation is important.

How to Select the Correct Sealing Film for Your CPET Tray

A 250mm roll width alone does not guarantee compatibility. The film structure and sealing layer must be selected according to the complete packaging system.

1. Confirm the Tray Material and Flange

Provide the exact CPET tray material, supplier, dimensions, flange width, flange condition and any surface coating. A physical tray sample is preferable when developing a new sealing-film specification.

2. Define the Food and Packaging Process

Specify whether the product is dry, oily, acidic, sauce-based, chilled, frozen, hot-filled or cooked after sealing. Seal-area contamination and food composition may influence the required film structure and sealing performance.

3. Provide Tray Sealing Machine Information

Provide the tray sealer brand, model, heating method, sealing-plate design, line speed, roll direction and current operating parameters. Film performance depends on the combined effects of sealing temperature, pressure and dwell time.

4. Define the Required Opening Performance

Confirm whether the finished package needs easy-peel opening, a stronger lock-up seal, tamper evidence or high resistance to leakage during transportation.

5. Confirm Storage and Cooking Conditions

State the minimum storage temperature, maximum cooking temperature, heating duration, microwave or conventional-oven use, required shelf life and distribution conditions.

6. Conduct a Production-Line Trial

Test the proposed film on the actual tray sealing line. Check roll tracking, cutting, sealing consistency, peel force, leakage resistance, appearance after storage and performance after the intended heating cycle.

Tray Sealing Performance and Quality Checks

A successful lidding-film project requires more than selecting a roll width. HSQY recommends evaluating the complete tray, film, food and machine combination before full commercial production.

• Seal integrity: Inspect the entire tray flange for channels, wrinkles, incomplete seals and contamination.

• Peel consistency: Confirm that the lid opens at the required force without excessive tearing, stringing or residue.

• Leak resistance: Test sauce-based and liquid-rich foods under realistic handling and transportation conditions.

• Machine performance: Confirm smooth unwinding, tracking, indexing and cutting at the target line speed.

• Temperature performance: Evaluate the pack after freezing, thawing, microwaving or oven heating as applicable.

• Retail appearance: Check transparency, condensation, print registration and film flatness.

• Shelf-life testing: Conduct appropriate product-specific shelf-life and food-safety validation.

Frequently Asked Questions About 250mm Tray Sealing Film

What is 250mm tray sealing film used for?

It is used as a heat-sealed lid for compatible food trays. Typical applications include CPET ready meals, airline meals, frozen meals, institutional catering, meals on wheels and prepared retail foods.

Will this film seal every CPET tray?

Not automatically. Compatibility depends on the CPET formulation, flange surface, tray supplier, sealing layer, machine settings and packed food. HSQY recommends testing the film with the actual tray before bulk ordering.

Is the 250mm lidding film easy to peel?

Easy-peel grades are available. The target peel force should be confirmed according to the tray dimensions, flange width, product weight, heating process and consumer-opening requirements.

Can you supply a stronger weld-seal or lock-up film?

Stronger-seal structures can be discussed for applications requiring increased package integrity. HSQY should review the tray, food, distribution conditions and required opening method before recommending a film.

Can the sealing film be used in a microwave or conventional oven?

Suitable grades can be developed for microwaveable and ovenable CPET meal-tray applications. The maximum temperature and heating time depend on the selected film structure, tray, food and cooking conditions. The complete package must be tested before commercial use.

Is the film suitable for frozen meals?

Freezer-compatible grades are available. Buyers should specify the minimum storage temperature, freezing duration, transport conditions and whether the package will move directly from freezer to microwave or oven.

Does the film have anti-fog properties?

Anti-fog treatment is optional. It can help maintain visibility when condensation may form inside chilled or refrigerated food packages.

Can you customize the width, thickness and roll length?

Yes. In addition to the standard 250mm by 500-metre roll, HSQY can discuss custom widths, thicknesses, roll lengths, core sizes and roll diameters according to the tray sealing machine.
