Easy-Peel BOPET/CPP Lidding Film for Trays

What Is Easy-Peel BOPET/CPP Lidding Film?

Easy-peel BOPET/CPP lidding film is a laminated tray-sealing film designed to form a secure but consumer-friendly peel seal on compatible polypropylene trays and containers. The BOPET outer layer provides clarity, tensile strength, dimensional stability, puncture resistance, and a printable surface. The specially formulated CPP sealing layer controls heat sealing and peel force.

Unlike a standard CPP weld-seal film, an easy-peel CPP structure is engineered to release from the tray rim with a defined opening force and reduced tearing, shredding, or residue. Seal strength must remain high enough for filling, handling, distribution, chilled storage, and retail display.

HSQY supplies nominal thicknesses from 0.052mm to 0.09mm, widths from 150mm to 900mm, and standard 500m rolls with custom conversion available. Anti-fog, printing, high barrier, MAP, low-temperature, microwave, and retort performance require the appropriate grade and application-specific testing.

Why Choose Easy-Peel Film for PP Trays?

• Consumer-friendly opening: Controlled peel force allows the lid to be removed without scissors or excessive effort.

• Clean rim appearance: A correctly matched grade can reduce film shredding, stringing, and sealant residue.

• Reliable package integrity: The seal can withstand handling and distribution while remaining peelable.

• High clarity and gloss: Transparent BOPET/CPP supports product visibility and retail presentation.

• Custom anti-fog: Helps maintain visibility for chilled meals, salads, produce, meat, dairy, and prepared foods.

• Custom printing: Supports branding, instructions, traceability, barcodes, and transparent viewing windows.

• Custom barrier: High-barrier options can support MAP and shelf-life requirements when standard BOPET/CPP is insufficient.

• High-speed line compatibility: Roll dimensions, friction, winding, and sealing window can be matched to tray-sealing equipment.

How Easy-Peel CPP Differs from Standard CPP

How the BOPET/CPP Easy-Peel Structure Works

Easy-Peel BOPET/CPP Film Specifications

The specifications below retain the current commercial values while clarifying which functions are standard and which require a separate film grade. Final guaranteed properties should be documented in the approved technical data sheet, sample approval, and purchase order.

Which Trays Can Easy-Peel BOPET/CPP Seal?

A film marketed as compatible with PP, PET, and PE normally uses a specially engineered universal sealant layer. That capability should be confirmed by tray-specific seal testing rather than inferred from the BOPET/CPP material name.

Understanding Peel Force and Peel Failure

Sealing Window and Line-Trial Requirements

A reliable easy-peel film needs a practical sealing window, not just one successful laboratory seal. The operating window should remain stable as production speed, tray temperature, flange contamination, pressure, dwell time, and tooling conditions vary.

• Seal initiation temperature: Lowest temperature that creates an acceptable seal.

• Upper sealing limit: Maximum temperature before the seal becomes too aggressive or the film distorts.

• Pressure and dwell time: Must suit the machine speed and tooling design.

• Contamination tolerance: Test moisture, oil, sauce, powder, and food particles on the flange.

• Peel after storage: Measure opening force after ambient, chilled, and accelerated ageing.

• Peel direction: Test from the actual tray peel tab and consumer opening angle.

• Seal consistency: Evaluate every side, corner, compartment, and cavity of multi-up tooling.

Anti-Fog and High-Barrier Options

Anti-fog treatment can reduce condensation and improve product visibility for chilled foods. Specify the anti-fog side, seal side, winding direction, storage temperature, product moisture, and required shelf life.

Standard BOPET/CPP provides general moisture and aroma protection but should not automatically be described as a high oxygen-barrier film. For MAP or oxygen-sensitive food, request a structure with defined OTR and WVTR values and test the tray and lid as one complete barrier package.

Custom Printing and Retail Presentation

Custom printing can include logos, product names, ingredients, preparation instructions, barcodes, QR codes, date-code areas, traceability, and transparent viewing windows.

• Print method: Flexographic or gravure printing according to graphics and volume.

• Print orientation: Surface or reverse printing according to the laminate design.

• Color control: Pantone or CMYK references and agreed color tolerances.

• Print repeat: Must match the tray-sealer cutting and tooling layout.

• Eye mark: Confirm size, position, color, and distance from the film edge.

• Seal-free area: Keep critical graphics and coding away from seal and cut zones.

• Proof approval: Approve artwork version, orientation, winding direction, and roll label before production.

Tray-Sealer and Roll Compatibility

Provide the machine brand and model, film width, core inside diameter, maximum outer diameter, roll weight, winding direction, seal-side orientation, eye-mark sensor, tooling layout, operating speed, temperature, pressure, and dwell time.

Production trials should evaluate web tracking, tension, cutting, seal continuity, peel-force range, film shredding, sealant residue, leakage, contamination tolerance, print registration, anti-fog performance, MAP retention, and package appearance.

Quality-Control Requirements

• Thickness profile: Influences stiffness, roll build, tracking, and peel behavior.

• Lamination bond strength: Confirms BOPET and CPP remain securely bonded.

• Peel-force range: Should be defined using an agreed test speed, angle, strip width, and conditioning method.

• Seal initiation temperature: Establishes the lower limit of the operating window.

• Coefficient of friction: Affects unwinding and machine transport.

• Anti-fog performance: Should be tested at the actual product and storage conditions.

• Optical quality: Includes haze, gloss, gels, scratches, black spots, and contamination.

• Roll quality: Includes edge alignment, telescoping, wrinkles, joints, core condition, and winding direction.

Frequently Asked Questions

What is easy-peel BOPET/CPP lidding film?

It is a laminate with a BOPET outer layer and a modified CPP sealant designed to seal securely to a compatible PP tray while opening with controlled peel force.

Is easy-peel BOPET/CPP mainly used for PP trays?

Yes. The modified CPP sealant is primarily designed for compatible polypropylene sealing surfaces. The exact tray resin and flange should still be tested.

Can it seal PET, CPET, or PE trays?

Not automatically. PET and PE surfaces may require a different or universal sealant layer. Compatibility should be confirmed using the actual tray.

What is the difference between easy peel and lock seal?

Easy peel opens with controlled force. Lock seal creates a stronger permanent bond that may tear the film or distort the tray rim during opening.

Can the peel force be customized?

Yes. Light, medium, or hard peel can be developed within practical limits. Provide the target force, test method, tray sample, and storage conditions.

What causes film shredding during opening?

Common causes include excessive sealing temperature, a narrow sealing window, unsuitable film stiffness, incompatible tray resin, excessive peel force, poor tray-flange geometry, or storage-related changes.

Is anti-fog easy-peel film available?

Yes. Anti-fog treatment can be added for chilled foods where condensation may reduce product visibility.

Can high-barrier easy-peel film be supplied?

Yes, as a separate multilayer structure. Provide the target OTR, WVTR, MAP gas mixture, food type, storage temperature, and shelf-life requirement.

Is the standard grade microwaveable or ovenable?

No. The current standard grade is listed as not microwaveable or ovenable. A qualified heat-resistant grade requires separate development and testing.

Is the standard grade freezer safe?

No. The current page lists it as not freezer safe. A low-temperature grade should be tested for brittleness, impact, seal retention, and peel behavior.

Can the film be custom printed?

Yes. Printing can include branding, ingredients, instructions, barcodes, QR codes, date-code areas, and transparent product windows.

What sizes are available?

The current page lists 0.052–0.09mm thickness, 150–900mm width, and 500m standard roll length, with custom roll conversion available.

How is easy-peel performance tested?

Peel testing should define specimen width, peel angle, speed, conditioning, tray direction, and whether the result is measured before or after storage.

What is the minimum order quantity?

The current stated MOQ is 1000kg. Trial quantities depend on stock, width, printing, barrier, and peel-force requirements.

Can I request samples before bulk production?

Yes, subject to material availability and specification. Send the PP tray sample, machine details, food application, film dimensions, and target peel behavior.
