START WITH COMPATIBILITY

The right film starts with the tray flange

A film can look suitable and still deliver weak seals, tearing or contamination failures. The first question is not simply “PET or PP?”—it is which material is present on the tray’s sealing surface.

Best practice: confirm tray structure, target seal style, packed food, process temperature and machine settings before a production run.
QUICK MATCHING GUIDE

Choose a practical starting structure

These are starting points for sampling, not universal specifications. Final suitability must be confirmed on your tray and sealing line.

Tray / flange Recommended starting point Available seal options Trial focus
APET / PETMono PET or coated flange Coated BOPET or PET-compatible sealant Easy peel or lock seal Coating type, clarity, peel consistency
PET/PEPE sealing surface PET/PE with a PE-compatible sealant Easy peel, lock seal, anti-fog Leak resistance and chill performance
CPETTemperature-resistant tray Validated CPET-compatible heat-resistant film Easy peel or lock seal Oven/microwave cycle and post-process seal
PPPP sealing surface PP-compatible coated film or PET/PA/RCPP structure Peelable, lock seal, retort option Process temperature and opening force

02

Fresh Produce

Cut fruit, vegetables and salads where clarity and anti-fog help presentation.

03

Meat & Poultry

Leak-sensitive and MAP packs requiring dependable seals and tailored barrier.

PUBLISHED REFERENCE DATA

Use test values as a baseline, then qualify your grade

The values shown are reference figures published on HSQY’s current category page for a representative film. They are not guaranteed values for every structure, thickness or test condition.

Request a grade-specific technical data sheet, compliance documents and samples before commercial approval.

35 ± 2 μm Reference thickness
± 2 mm Reference width tolerance
≥ 3.5 N/15 mm Heat-seal strength*
≤ 3% Reference shrinkage

B2B LIDDING FILM FAQ

Questions procurement and packaging teams ask

These answers help food manufacturers, distributors and packaging buyers prepare a more complete sourcing enquiry. Grade-specific suitability still requires tray and line validation.

Ask a Technical Question

How do I match lidding film to an APET, CPET, PP or PET/PE tray?

Match the film’s sealant layer to the material exposed on the tray flange. Confirm the complete tray structure, any coating, required seal style, food, process temperature and machine settings, then validate the shortlist on the actual line.

What specifications should a B2B buyer provide for a lidding film quotation?

Provide the tray material and flange layer, food and packing process, easy-peel or lock-seal requirement, barrier and anti-fog targets, roll width, core ID, maximum roll OD, sealing machine, printing needs, forecast volume and destination. A physical tray sample improves film matching.

What is the difference between easy-peel and lock-seal lidding film?

Easy-peel film prioritizes controlled consumer opening; lock-seal film prioritizes stronger package integrity. Select between them according to product weight, liquids, distribution stress, tamper-evidence needs and the intended opening experience.

When should food manufacturers specify anti-fog lidding film?

Specify anti-fog performance when condensation could reduce product visibility, particularly for chilled produce, ready meals and protein packs. Test the film under the actual filling, cooling, storage and retail temperature cycle.

When is high-barrier lidding film needed for MAP food packaging?

High-barrier film is considered when the food, target shelf life and gas atmosphere require lower oxygen or moisture transmission. The lidding film and tray must provide compatible barrier performance; confirm the target values for the selected structure.

Can lidding film be used for CPET oven heating or PP retort processing?

Heat-resistant and retort film structures are available, but the polymer name alone does not confirm suitability. Validate the exact film, tray, food, maximum temperature, cycle time, pressure and seal conditions as a complete pack.

Can HSQY supply custom-printed lidding film rolls?

Custom printing can be discussed for suitable film structures. Share the artwork, number of colors, repeat length, registration requirements, roll direction, machine details and forecast volume for a feasibility review.

How are MOQ, sampling and lead time confirmed for a wholesale order?

MOQ, sample format and lead time depend on the film structure, width, thickness, printing and order volume. Send the complete specification and delivery destination for a project-specific quotation and schedule.
