What Is 280mm Tray Sealing Film?
280mm tray sealing film is a wide lidding-film roll developed for heat-sealing compatible CPET food trays on manual, semi-automatic, or automatic tray-sealing equipment. The standard roll size on this page is 280mm wide × 500m long, making it suitable for larger tray formats, multi-compartment meal trays, and tooling layouts that require a wider film web.
HSQY supplies PET- or BOPET-based lidding-film structures with an application-specific sealing layer. Available options include clear film, custom printing, easy peel, medium peel, weld seal, anti-fog, high barrier, freezer-compatible, microwave-compatible, and application-specific ovenable grades.
Film width alone does not determine tray compatibility. Before commercial production, the film should be tested with the actual CPET tray, flange design, sealing machine, tooling, food product, sealing temperature, pressure, dwell time, storage conditions, and reheating process.

Is 280mm the Correct Film Width for Your Tray?
The lidding-film web must cover the full sealing-tool layout with sufficient allowance for registration, cutting, and edge trim. A 280mm roll is appropriate only when the tray dimensions and the tray-sealer tooling fit within the usable film width.

Liquid-containing meals, heavy products, and maximum-security packaging |
Optional Anti-Fog and High-Barrier Structures
Anti-fog treatment helps reduce condensation on the inside surface of the film and improves product visibility in refrigerated display. It is useful for chilled ready meals, meat, vegetables, bakery products, dairy, and foods with high moisture content.
High-barrier versions may incorporate EVOH or another barrier layer for modified atmosphere packaging. Buyers should provide the target oxygen transmission rate, water-vapor transmission rate, gas mixture, food type, storage temperature, and shelf-life target.
Ovenable and Microwaveable CPET Packaging
CPET trays are frequently selected for frozen, microwave, and conventional-oven meals. However, an ovenable tray does not automatically make every lidding film suitable for the same temperature. The PET carrier, sealant, adhesive, ink, coating, seal area, and complete package must all remain suitable during the specified heating cycle.
For oven or microwave projects, provide the maximum temperature, heating time, whether the film remains on the tray during cooking, venting requirements, food type, fill weight, freezer or chilled storage conditions, and the required food-contact regulations.
Typical Applications for 280mm Lidding Film
Large CPET ready-meal trays
Two-compartment and three-compartment meal trays
Family-size and catering meal trays
Airline, railway, hospital, school, and institutional meals
Frozen pasta, rice, meat, vegetable, and prepared meals
Bakery products, desserts, deli foods, and prepared snacks
MAP and extended-shelf-life food trays

Tray-Sealer Compatibility and Line Testing
Seal quality depends on the machine, sealing temperature, pressure, dwell time, film tension, tooling flatness, tray rigidity, flange cleanliness, food contamination, and production speed. Excessive heat can cause shrinkage or overly aggressive seals, while insufficient heat can cause incomplete bonding and leakage.
Before mass production, test roll feeding, web tracking, cutting accuracy, seal continuity, peel force, leakage, burst strength, wrinkling, print registration, anti-fog performance, freezer performance, MAP gas retention, microwave performance, and oven performance when applicable.

Frequently Asked Questions
What is the standard size of this tray sealing film?
The standard roll size on this page is 280mm wide × 500m long. Thickness, roll length, core, outer diameter, and other roll specifications can be customized subject to production feasibility.
Which CPET trays require a 280mm film roll?
A 280mm roll may suit large trays, multi-compartment trays, or tooling layouts that place more than one tray across the film web. The actual tray outside dimensions, flange, cavity layout, and trim allowance must be checked.
Can 280mm lidding film be used on any tray-sealing machine?
No. The tray sealer must accept the 280mm web width, core size, roll weight, maximum outer diameter, winding direction, and film tension. Send the machine brand and model before ordering.
Is easy-peel 280mm tray sealing film available?
Yes. Easy-peel, medium-peel, and weld-seal versions can be evaluated. The target peel force and failure mode must be tested with the actual CPET tray and production conditions.
Is 280mm anti-fog lidding film available?
Yes. Anti-fog treatment can be supplied for chilled meals, meat, produce, bakery, dairy, and other moist foods where condensation may reduce visibility.
Can HSQY supply high-barrier 280mm film for MAP?
High-barrier structures can be evaluated for modified atmosphere packaging. Provide the required OTR, WVTR, gas mixture, food type, storage temperature, and target shelf life.
Can standard PET/PE lidding film be used at 200°C?
It should not be assumed that every PET/PE laminate is suitable for 200°C. Conventional-oven use requires an application-specific structure validated with the exact film, tray, food, temperature, heating time, and cooking method.
Can the 280mm film be custom printed?
Yes. Custom printing can include logos, graphics, preparation instructions, product information, traceability content, and date-code areas. Provide the artwork, colors, print repeat, eye-mark location, and annual volume.
Why does wide lidding film wrinkle or track incorrectly?
Common causes include uneven tension, incorrect roll alignment, unsuitable core or outer diameter, damaged roll edges, inconsistent film thickness, poor unwind control, tooling misalignment, or excessive heat shrinkage.
Why does the seal leak or peel inconsistently?
Leakage or inconsistent peel may result from incompatible sealant chemistry, contaminated tray rims, incorrect temperature, insufficient pressure or dwell time, uneven tooling, tray deformation, food oils, condensation, or unsuitable storage conditions.
Can the film seal APET, PET/PE, or PP trays?
Different tray materials may require different sealing layers. A grade developed for CPET should not automatically be used for APET, PET/PE, PP, aluminium, or coated paperboard without compatibility testing.
What is the minimum order quantity?
The current stated MOQ is 500kg. Sample and trial quantities depend on available stock, required film structure, roll width, and conversion requirements.
How long is the production lead time?
Typical lead time is approximately 7–15 days for standard orders after deposit and final specification approval. Printed, high-barrier, or special thermal grades may require additional time.
Can I request a sample before placing a bulk order?
Yes, subject to stock and specification. Send the tray sample, tray dimensions, machine model, required roll configuration, seal type, food application, storage conditions, and heating process.
How should 280mm lidding-film rolls be stored?
Store rolls in their original protective packaging in a clean, dry area away from direct sunlight, excessive heat, moisture, dust, solvents, and strong odors. Keep wide rolls properly supported and allow cold-stored material to acclimatize before opening.
