PET/CPP Lamination Film

PET/CPP Lamination Film Manufacturer

HSQY manufactures PET/CPP lamination films for snack packaging, confectionery, bakery products, frozen foods, instant noodles, dry foods, sachets, dry pet food and customized flexible packaging applications.

PET/CPP is a two-layer or multilayer flexible packaging structure that combines an outer polyethylene terephthalate film with an inner cast polypropylene heat-sealing film.

The PET layer provides tensile strength, dimensional stability, surface gloss, printability and resistance to ordinary handling and abrasion.

The CPP layer provides heat-sealing performance, hot tack, flexibility, grease resistance, moisture protection and compatibility with pouch-making and automatic packaging equipment.

Standard PET/CPP film is normally transparent and glossy, allowing consumers to view the packaged product. Colored, matte, printed, anti-fog, deep-freeze and specialized heat-resistant structures are available according to project requirements.

PET/CPP provides useful moisture, aroma and gas protection for many dry-food applications, but it should not automatically be described as an ultra-high-barrier structure.

Products requiring very low oxygen or water-vapor transmission may require an additional PVDC, EVOH, AlOx, SiOx, metallized or aluminum-foil barrier layer.

HSQY publishes a customizable total thickness range of approximately 0.045mm to 0.35mm and widths from approximately 160mm to 2600mm. Actual availability depends on the PET and CPP thicknesses, printing width, lamination process, slitting capability, roll diameter and packaging equipment.

Standard PET/CPP, deep-freeze PET/CPP, anti-fog PET/CPP and retort-grade PET/RCPP should be treated as separate products with different formulations and validation requirements.

What Is PET/CPP Lamination Film?

PET/CPP lamination film is produced by bonding a PET outer film to a CPP inner film using a suitable laminating adhesive or another approved lamination process.

PET is normally used as the printed or structural layer because it provides high tensile strength, good dimensional stability, transparency and a smooth printing surface.

CPP is normally used as the inner sealant layer because it provides heat-sealability, hot-tack performance, flexibility and resistance to oil and grease.

The two layers can be adjusted according to the required stiffness, transparency, seal temperature, package weight, storage temperature and packaging-machine speed.

Structure of PET/CPP Lamination Film

PET Outer Layer

The PET outer layer provides mechanical strength, stiffness, heat resistance, dimensional stability, clarity and a suitable surface for gravure or flexographic printing.

Reverse printing can position the ink between PET and CPP, reducing direct abrasion of the printed graphics and improving shelf appearance.

CPP Inner Sealant Layer

The CPP layer provides the heat-sealing surface and contributes flexibility, hot tack, moisture resistance, puncture resistance and grease resistance.

The CPP formulation can be adjusted for standard packaging, low-temperature sealing, anti-fog performance, deep-freeze storage or retort processing.

Laminating Adhesive

The adhesive bonds the PET and CPP films and affects lamination strength, odor, chemical resistance, temperature performance and shelf-life stability.

Adhesive selection and curing time must be matched to the product, printing ink, filling process, storage conditions and any thermal processing requirement.

PET/CPP Lamination Film Specifications

Standard and Functional PET/CPP Film Grades

Barrier Performance of PET/CPP Film

Standard PET/CPP provides good moisture protection and useful resistance to oxygen, aromas, grease and external contamination for many dry-food applications.

It should not automatically be classified as an ultra-high-barrier film because the final performance depends on PET thickness, CPP thickness, adhesive, coatings, printing, pouch seals and storage conditions.

Products requiring very low oxygen transmission may require an additional EVOH, PVDC, AlOx, SiOx, metallized or aluminum-foil layer.

OTR and WVTR specifications should identify the test method, temperature, relative humidity and exact film structure.

PET/CPP Heat-Sealing Performance

CPP is selected as the inner layer because it can provide strong heat sealing, hot tack and good packaging-line machinability.

Seal performance depends on the CPP grade, seal temperature, pressure, dwell time, jaw design, line speed and contamination in the seal area.

• Determine the heat-seal initiation temperature.

• Define the validated operating seal window.

• Measure seal strength after cooling and conditioning.

• Measure hot-tack strength for high-speed lines.

• Test seals through oil, powder, crumbs or moisture where applicable.

• Inspect wrinkles, channel leaks, burned seals and distorted bags.

• Perform burst, vacuum, drop or another agreed package-integrity test.

Is PET/CPP Suitable for Retort Packaging?

Standard PET/CPP film should not automatically be used for retort sterilization, pressure cooking or high-temperature boiling.

Retort packaging requires retort-grade CPP or RCPP, a suitable PET film, retort-grade adhesive, compatible ink and validated pouch-making conditions.

Products requiring greater puncture resistance or stronger barrier may use structures such as PET/NY/RCPP, PET/AL/RCPP or PET/NY/AL/RCPP.

The package must be tested using the actual food, acidity, oil content, sterilization temperature, sterilization time, pressure, cooling process and shelf-life target.

PET/CPP Film for Frozen Food Packaging

Frozen-food packaging should use a CPP grade designed to maintain flexibility, impact resistance and seal strength at the required storage temperature.

Standard room-temperature packaging film may become brittle or lose seal performance during freezing, impact or repeated cold-chain handling.

• Minimum storage and transport temperature.

• Cold-impact and puncture resistance.

• Seal strength after freezing.

• Drop and vibration resistance.

• Flexibility after temperature cycling.

• Resistance to sharp frozen-food edges.

• Condensation and anti-fog requirements.

Applications of PET/CPP Lamination Film

• Snack packaging: Chips, crackers, nuts, dried fruit and extruded snacks.

• Confectionery packaging: Candy, chocolate, cookies and sweet products.

• Bakery packaging: Bread, cakes, pastries and bakery ingredients.

• Instant-food packaging: Noodles, pasta, soup mixes and seasoning sachets.

• Dry-food packaging: Rice, grains, cereal, powder and dried ingredients.

• Frozen-food packaging: Frozen vegetables, dumplings, bakery products and prepared foods using a deep-freeze grade.

• Fresh-produce packaging: Anti-fog and perforated structures developed for the specific product.

• Dry pet-food packaging: Pet treats, supplements and dry pet-food products.

• Pharmaceutical secondary packaging: Non-sterile sachets and outer packaging subject to application-specific compliance.

• Industrial packaging: Components and products requiring a clean, printable and heat-sealable laminate.

Medical and Pharmaceutical Packaging Limitations

Standard food-packaging PET/CPP should not automatically be promoted for sterile surgical-instrument packaging, IV bags or pharmaceutical blister packs.

These applications may require dedicated medical polymers, sterilization compatibility, microbial-barrier performance, extractables testing, seal validation and package-aging studies.

PET/CPP may be considered for selected non-sterile medical products, pharmaceutical secondary packaging or specialty sachets only after the complete structure and regulatory requirements are confirmed.

Flexible Packaging Formats

• Vertical form-fill-seal roll stock.

• Horizontal form-fill-seal roll stock.

• Three-side-seal pouches.

• Four-side-seal pouches.

• Center-seal and fin-seal bags.

• Pillow bags.

• Flat pouches.

• Gusseted bags.

• Stand-up pouches.

• Stick packs and single-dose sachets.

• Custom converted packaging formats.

Custom Printing and Artwork Requirements

PET provides a smooth surface for high-quality gravure, flexographic or other compatible printing processes.

Reverse printing places the ink between the PET and CPP layers, helping protect the graphics from surface abrasion and direct product contact.

Food-Contact Compliance Requirements

Food-contact suitability depends on the final approved PET/CPP structure rather than only the names PET and CPP.

The compliance assessment should include the PET film, CPP film, laminating adhesive, printing ink, primer, pigment, coating, additives and manufacturing conditions.

Buyers should specify the food type, direct or indirect contact, contact duration, filling temperature, storage temperature, heating process and destination market.

Applicable documents may include a food-contact declaration, formulation statement, migration test report, residual-solvent report and supporting regulatory information.

SGS should be described according to the exact test performed. FDA should not be presented as a general product certification, and ISO 9001 does not independently prove food-contact safety.

Recyclability and Alternative Structures

PET/CPP combines polyester, polypropylene, adhesive and potentially printing ink or coatings.

The different polymer families are difficult to separate in many conventional mechanical recycling systems, so PET/CPP should not automatically be described as recyclable in every market.

Actual recyclability depends on layer proportions, inks, adhesives, coatings, package accessories and local collection and recycling infrastructure.

Mono-PP or mono-PE packaging structures can be evaluated when improved compatibility with a polyolefin recycling stream is a project priority.
