HSQY Customized Thick Food Tray/Box Packaging Film Sealing

What Is Custom Thickness Food Tray Sealing Film?

Custom thickness food tray sealing film is flexible lidding rollstock manufactured or converted to a selected gauge, width, roll length, core, and functional structure for sealing compatible food trays and boxes. This page covers nominal thicknesses from 0.05mm to 0.10mm, equal to 50–100 microns.

HSQY supplies PET- or BOPET-based laminated films with application-specific sealing layers for CPET trays and other compatible tray surfaces. Available options include clear film, custom printing, easy peel, medium peel, weld seal, anti-fog, high barrier, MAP, freezer-compatible, microwave-compatible, and application-specific ovenable structures.

Increasing film thickness can improve stiffness, puncture resistance, web stability, and handling, but it also increases material use and may change sealing, cutting, peel, roll weight, and machine performance. The correct gauge should therefore be selected through testing rather than choosing the thickest film by default.

Why Customize the Lidding-Film Thickness?

• Machine stability: The correct gauge can improve web tracking, tension control, cutting, and sealing on commercial tray sealers.

• Puncture resistance: A heavier gauge may be useful for products with sharp edges, bones, frozen components, or demanding distribution.

• Package stiffness: Thicker film can provide a more substantial feel and reduce excessive flutter or curling.

• Peel performance: Gauge influences how the film bends, tears, and peels from the tray rim.

• Thermal behavior: Thickness can affect heat transfer, shrinkage, sealing response, and reheating performance.

• Barrier design: The total gauge may change when EVOH, PA, coatings, or other functional layers are added.

• Material optimization: The lowest gauge that consistently meets protection and line-performance requirements can reduce material consumption and roll changes.

50–100 Micron Thickness Selection Guide

The following guidance explains typical engineering trade-offs. It is not a universal recommendation. Final suitability must be confirmed on the actual tray, sealing equipment, and packaged product.

Custom Thickness Sealing Film Specifications

The specifications below retain the current product information while separating standard values from project-specific options. Final guaranteed values should be documented in the technical data sheet, approved sample, and purchase order.

How the Multilayer Film Structure Works

Tray Material Compatibility

Film thickness does not determine which tray resin it will seal. Compatibility is controlled mainly by the sealing layer, tray flange, and process conditions. Test the exact tray before commercial orders.

Easy-Peel, Medium-Peel, and Weld-Seal Options

Seal and peel performance may change when film gauge changes. Each proposed thickness should be tested for seal initiation, operating window, peak peel force, clean-peel behavior, leakage, and tray-rim damage.

Anti-Fog, High-Barrier, and MAP Structures

Anti-fog treatment helps reduce condensation and improve visibility in refrigerated display. High-barrier grades can incorporate EVOH or another functional layer to control oxygen and maintain a modified atmosphere.

For barrier projects, provide the required OTR, WVTR, gas mixture, food type, filling temperature, storage temperature, and target shelf life. The barrier performance should be measured on the approved complete laminate, not inferred from thickness alone.

Freezer, Microwave, and Oven Applications

The current page states a range from −40°C to 220°C. Such a claim should apply only to a validated application-specific grade. The thermal suitability of a CPET tray does not automatically apply to the lidding film, ink, adhesive, coating, or seal.

For thermal applications, provide the lowest storage temperature, maximum heating temperature, duration, food load, venting requirement, whether the lid remains on during cooking, and the relevant food-contact rules. Conduct completed-pack tests before launch.

Effect of Thickness on Tray-Sealer Performance

• Roll weight: Thicker film increases roll weight for the same width and length.

• Metres per roll: A thicker gauge may reduce the available length within the machine’s maximum roll diameter.

• Heat transfer: Gauge can change sealing response and the required temperature, pressure, or dwell time.

• Cutting: Heavier film may require different knife condition, cutting pressure, or tooling maintenance.

• Web tension: Tension settings may need adjustment to prevent wrinkling, stretching, or poor tracking.

• Peel behavior: A thicker film may feel stiffer and may change the angle or force required to open the package.

• Line speed: Verify stable operation at the planned commercial speed, not only during slow sample trials.

Gauge Optimization and Sustainability

A thicker film is not automatically a better film. Gauge optimization aims to use the lowest thickness that consistently meets puncture, barrier, sealing, peel, distribution, and machine-performance requirements. This may reduce material weight, roll changes, transport weight, and packaging cost.

Any recyclability claim should be assessed for the complete tray-and-film system, including resins, adhesives, inks, coatings, labels, local collection rules, and actual recycling infrastructure.

Quality and Compliance Documentation

HSQY can provide available quality-management, inspection, and material documents for the approved film grade. Buyers should request the technical data sheet, certificate of analysis, food-contact declaration, migration or compliance reports, roll inspection criteria, and destination-market documents required for the exact laminate.

ISO 9001 is a quality-management-system certification and should not be presented as product-specific proof of food-contact safety. FDA or SGS claims should identify the exact report, film structure, test scope, date, and applicable food-contact conditions.

Frequently Asked Questions

What is custom thickness food tray sealing film?

It is lidding-film rollstock manufactured or converted to a selected nominal gauge, width, roll configuration, sealing layer, and functional structure for a specific tray and packaging process.

Which thicknesses are available?

This page covers nominal thicknesses from 0.05mm to 0.10mm, equal to 50–100 microns. Final tolerances should be confirmed in the approved technical specification.

Is thicker sealing film always better?

No. Thicker film may improve stiffness and puncture resistance, but it also increases material use, roll weight, and heat-transfer requirements. The optimum gauge is the lowest thickness that passes all package and line tests.

How does thickness affect tray-sealer performance?

Thickness can affect roll weight, metres per roll, web tension, heat transfer, cutting, tracking, seal window, peel force, and maximum production speed.

Can one film thickness seal every tray material?

No. Tray compatibility depends mainly on the sealing layer and tray flange chemistry. CPET, APET, PET/PE, PP, aluminium, and paperboard may require different structures.

Is easy-peel custom thickness film available?

Yes. Easy-peel, medium-peel, and weld-seal structures can be evaluated at different gauges. Each proposed thickness should be tested on the actual tray.

Can anti-fog be added?

Yes. Anti-fog treatment can be added for refrigerated and moisture-rich foods where condensation may reduce product visibility.

Can high-barrier film be supplied for MAP?

Yes. High-barrier structures can be evaluated for MAP. Provide the required OTR, WVTR, gas mixture, food type, storage temperature, and shelf-life target.

Can standard BOPET/PE film be used from −40°C to 220°C?

A universal temperature claim should not be applied to every structure. The exact film, tray, seal, food load, storage condition, and heating cycle must be tested together.

Can the film be custom printed?

Yes. Flexographic or gravure printing can be evaluated for logos, product information, cooking instructions, barcodes, QR codes, and traceability.

Which roll dimensions can be customized?

Thickness, width, length, core ID, core length, roll weight, maximum outer diameter, seal-side orientation, and winding direction can be customized subject to feasibility.

What causes thick lidding film to wrinkle or track poorly?

Possible causes include incorrect tension, unsuitable roll build, damaged edges, excessive roll weight, core misalignment, thickness variation, poor unwind control, or incorrect machine settings.

What is the minimum order quantity?

The currently listed MOQ is 500kg. Trial quantities depend on stock, structure, gauge, width, printing, and conversion requirements.

How long is the production lead time?

Typical lead time is approximately 10–14 days after deposit and final specification approval. Printed, high-barrier, or special thermal grades may require additional time.

Can I request a sample before bulk production?

Yes, subject to available materials and specification. Send the tray sample, dimensions, machine details, required gauge, food application, storage conditions, and heating process.
