Custom Compostable PLA-Based Food Cling Film
Wallis custom compostable PLA-based food cling film is developed for wrapping fresh produce, bakery items, prepared foods, catering trays and other approved food-packaging applications. The transparent flexible film can be supplied in retail rolls, foodservice rolls or customized converting formats for packaging distributors, supermarkets, restaurants, catering companies, food processors and private-label brands.
Flexible compostable cling film may be formulated using PLA, PBAT and other compostable components. Standard unmodified PLA is generally too rigid for high-stretch cling wrapping, so commercial flexible films often use blends or specialized formulations. The precise resin composition, plant-based content, food-contact suitability and certification scope depend on the selected grade and must be documented before an order is approved.
Compostable film should not be described as rapidly disappearing in landfill, soil, rivers or the open environment. Industrial-compostable and home-compostable claims apply to different controlled conditions and certification programs. Buyers should verify that the intended collection or composting facility accepts flexible compostable packaging before selecting disposal language.

What Is Compostable PLA-Based Cling Film?
Compostable food cling film is a thin, flexible wrapping material formulated to adhere to compatible food trays and containers while providing temporary protection during handling or storage. Verified compostability is a property of the finished product under defined treatment conditions; it does not automatically demonstrate food-contact compliance, a particular shelf life or natural-environment degradation.
Why Flexible Film Usually Uses a Polymer Blend
PLA contributes renewable content and compostability potential but is naturally stiff. Flexible polyesters such as PBAT and other approved modifiers can improve elongation, softness, puncture resistance, sealing and cling behavior. The finished blend—not one individual resin—determines whether the wrap performs correctly and qualifies for the intended claim.
How Cling Performance Is Created
Cling depends on film formulation, surface properties, stretch, thickness, temperature and the material being wrapped. Performance may differ on glass, ceramic, stainless steel, paperboard, PLA trays, PP containers and direct food surfaces. Buyers should approve cling using the actual containers and foods rather than relying on a general “high cling” statement.
Intended End-of-Life Route
A compostable food wrap may support foodservice and retail programs with suitable separate collection. Some composting facilities reject flexible packaging even when a product has been certified, so disposal instructions should reflect local collection and acceptance rules.

PLA, PBAT and Compostable Film Formulations
| Component | Typical Function | Purchasing Consideration |
| PLA | Bio-based compostable polyester that can contribute clarity and renewable carbon | Pure PLA is typically too stiff for conventional cling-wrap handling |
| PBAT | Adds flexibility, elongation, toughness and film-processing stability | Usually fossil-derived, so compostable does not automatically mean fully bio-based |
| Compostable Modifiers | Adjust softness, cling, anti-blocking, processing and tear behavior | Every constituent must remain within food-contact and certification requirements |
| Finished Blend | Balances transparency, stretch, cling, puncture, cutting and compostability | Specify the certified finished film grade and production thickness |

Compostable Cling Film vs. PE and PVC Food Wrap
A material substitution should be qualified on cling, stretching, dispensing, food-contact suitability, shelf life and cost rather than environmental labels alone. The table summarizes selection criteria without assuming that one polymer always outperforms another.
| Factor | PLA-Based Compostable Wrap | Conventional PE / PVC Wrap |
| End-of-life classification | Potentially commercially or home compostable if the exact finished film is certified and accepted locally | Generally non-compostable; disposal or recycling depends on material and local collection |
| Cling to Trays | Depends strongly on formulation, surface and tray type; approve by sample | Commercial formulations vary in cling and release; compare using the same tray |
| Stretch and Handling | Blend composition and gauge govern elongation and tear response | Often mature high-speed dispensing solutions; verify process equivalence |
| Food Contact | Requires documentation for exact formulation and use conditions | Also requires suitable food-contact approval for intended conditions |
| Barrier and Shelf Life | Oxygen and moisture transmission must be measured for the food application | Different polymers provide different barrier profiles; run a same-food comparison |
| Procurement Decision | Define certification, buyer test plan, storage and end-of-life route | Define cost, functionality, food safety, shelf life and disposal route |
Key Performance Requirements
Cling to Containers and Trays
Film should adhere sufficiently to the target container without excessive blocking on the roll. Cling should be tested on the customer's trays, bowls, plates and containers at the intended temperature and humidity.
Stretch and Recovery
Controlled elongation helps the film conform around irregular food and tray shapes. Excessive stretch can create thin spots and tears, while insufficient stretch makes wrapping difficult. Tensile and elongation targets should be agreed in both machine and transverse directions.
Puncture and Tear Resistance
Sharp tray corners, bones, bakery crusts and stems can puncture thin film. Thickness and formulation should be matched to the product, and samples should be tested using the actual package geometry.
Transparency and Fogging
Clear appearance supports product presentation, but condensation can reduce visibility. Anti-fog performance should not be assumed unless the selected grade contains an approved anti-fog system and passes the required chilled-food test.
Cutting and Roll Dispensing
Film must unwind evenly, cut cleanly and avoid telescoping, excessive edge curl or premature tearing. Cutter design, roll tension and core fit should be evaluated as one dispensing system.
How to Test Cling, Stretch and Dispensing Performance
For accurate bulk-order qualification, test the finished film on the customer’s actual trays, cutting tools and handling line. Report the test temperature, humidity, film gauge, container material, wrapping method and pass/fail criteria.
Cling and Peel Tests
Check whether the film seals around glass, PET, PP, paperboard or foam trays without leaving loose corners or causing excessive self-cling. Compare peel force and package appearance after refrigeration and typical handling.
Stretch, Puncture and Wrapping Tests
Measure tensile elongation in machine and transverse directions and assess tearing around tray edges or protruding food. Agree on a practical maximum stretch ratio instead of publishing unverified performance numbers.
Roll Release, Cutter and Equipment Trials
Confirm roll outer diameter, core inner diameter, winding tension, unwinding force and compatibility with a slide cutter, serrated cutter or existing wrapping equipment. Automatic overwrappers and heated sealing systems require machine-specific trials; manual cling performance does not confirm machine compatibility.
Food Packaging Applications
| Application | Recommended Review |
| Fresh Fruit and Vegetables | Respiration, condensation, puncture from stems, refrigeration and shelf-life target |
| Bakery Products | Crust puncture, moisture retention, grease contact, freshness and wrapping speed |
| Prepared Meals and Catering Trays | Food temperature, tray material, cling, leakage, transport and re-heating instructions |
| Deli, Cheese and Meat | Fatty-food contact, oxygen exposure, odor transfer, freezer use and regulatory test conditions |
| Household Food Storage | Container types, refrigerator use, cutter safety, microwave labeling and disposal instructions |
Food-Contact Compliance and Migration Testing
Compostability certification and food-contact compliance are separate requirements. A film can be compostable but not approved for every food type, temperature or contact duration. The finished formulation must be assessed for the destination market and intended conditions of use.
Identify the destination country and applicable food-contact regulation.
Define aqueous, acidic, alcoholic, dairy, oily or fatty food contact.
Specify contact temperature and maximum storage or wrapping duration.
Include all additives, anti-fog agents, pigments and printing in the compliance review.
Request overall and specific migration reports where required.
Confirm odor and taste neutrality using the customer's food application when necessary.
Temperature, Microwave and Freezer Limitations
| Condition | Required Validation |
| Refrigeration | Cling, flexibility, condensation, odor and package integrity during the target shelf life |
| Freezer Use | Low-temperature brittleness, puncture, seal retention and thawing cycle for the exact grade |
| Warm Food | Film softening, cling, migration and direct-contact limits at the actual food temperature |
| Microwave | Do not claim microwave safety unless the complete film and use instructions have been specifically validated; vent the wrap where required |
| Oven or Grill | Not suitable unless a dedicated high-temperature product is separately tested and approved |
Barrier, Breathability and Shelf-Life Considerations
Cling film does not provide the same shelf-life performance for every food. Oxygen transmission, water-vapor transmission, film thickness, seal area, perforation and storage temperature affect product quality. Buyers should not assume that a compostable wrap will match PVC, PVDC or polyethylene film without a side-by-side shelf-life study.
Fresh Produce Respiration
Fruit and vegetables continue to respire after packing. Excessively restrictive packaging can create condensation or undesirable gas conditions, while excessive permeability can increase moisture loss. Perforation or a tailored gas-transmission rate may be required.
Moisture Retention for Bakery and Prepared Food
Water-vapor control influences softness, crispness and weight loss. The wrap should be tested with the exact bakery, prepared meal or deli product over the expected storage period.
Fat and Aroma Contact
Cheese, meat, sauces and oily foods require food-contact testing suitable for fatty simulants. Aroma retention and odor transfer should also be reviewed where product flavor is sensitive.
Industrial Composting and Home Composting Claims
| Claim | Meaning and B2B Requirement |
| Industrial Compostable | Designed for controlled commercial or municipal aerobic composting; confirm ASTM D6400, EN 13432, BPI, Seedling or OK compost INDUSTRIAL scope |
| Home Compostable | Requires separate certification for lower-temperature home-compost conditions, such as OK compost HOME or applicable regional program |
| Biodegradable | Too broad when used without environment, time and test method; avoid unsupported standalone claims |
| Bio-Based | Describes renewable carbon content, not composting performance; support percentage claims with an appropriate test |
| Marine or Soil Biodegradable | Not covered automatically by industrial or home compost certification; do not claim without specific testing |
For commercially compostable plastic packaging, buyers may request evidence against ASTM D6400, EN 13432 or other locally applicable standards. Commercial and home compostability are distinct certification scopes. The finished film, allowable thickness, print, SKU and permitted certification logo should be verified against the certificate holder before any product claim is printed.
Printing, Cutter Boxes and Private-Label Packaging
| Dispenser Box | Printed paperboard box with slide cutter or serrated edge, subject to safety and compostability messaging |
| Retail Artwork | Brand logo, dimensions, roll length, use instructions, warnings, barcode and importer information |
| Environmental Claims | Certification logo, disposal route and certificate number only when authorized for the exact product |
| Commercial Carton | Roll width, length, gauge, lot number, quantity, storage guidance and pallet labels |
| Film Printing | Possible for suitable projects, but ink adhesion, food contact and compostability must be reviewed |

Common Cling Film Problems and Troubleshooting
These examples help purchasing teams define sample-test acceptance criteria before repeat orders. Actual corrective action depends on the film grade, equipment, food and local compliance requirements.
| Observed Problem | Potential Cause | Recommended B2B Check |
| Film does not cling to the tray | Surface-energy difference, wrong film grade or low application pressure | Test approved formulation on the specific tray material at service temperature |
| Film is too sticky on the roll | Blocking, excess cling or storage heat | Review cling/release balance, winding tension and sealed storage |
| Tearing or holes during stretch | Low elongation, thin spots, sharp tray corners or damaged roll edges | Check film-gauge profile, MD/TD tensile properties and real-tray puncture trial |
| Film becomes cloudy in chilled storage | Condensed droplets, surface haze or insufficient anti-fog function | Perform a specified condensation test; approve a special anti-fog grade if needed |
| Uneven roll cutting or telescoping | Unsuitable cutter, winding tension, core fit or roll geometry | Confirm cutter design, core ID, roll OD, edge quality and winding stability |
| Unexpected food odor or taste | Unapproved formulation, print, additive or migration issue | Stop release and check batch traceability, sensory tests and food-contact documents |
| Film loses performance in storage | Heat, moisture, excessive age or wrong handling conditions | Recheck shelf-life data and packing, apply FIFO and trial aged samples |
Bulk-Buyer Approval Checklist
A signed reference sample and specification sheet should be used for recurring B2B supply. This reduces batch disagreements about cling, cutting performance and environmental labeling.
| Approval Item | Suggested Evidence |
| Film identity | Grade code, material composition disclosure as appropriate, manufacturing batch and technical datasheet |
| Key dimensions | Measured μm thickness, width, roll length, core ID and finished-roll outside diameter |
| Functional tests | Cling on buyer trays, MD/TD stretch, puncture, unwind and dispenser cutting results |
| Food-contact documentation | Declarations and migration testing appropriate for the destination market, food types and temperature/time |
| Environmental claim | Active certificate covering finished film formulation, permitted gauge, print and marked SKU |
| Shelf-life and transport | Storage conditions, sealed packing, labeling, lot traceability and agreed shelf-life guidance |
Custom Development and Sample Approval Process
Define the food application: Identify food type, container, temperature, storage duration and expected shelf life.
Select the material claim: Confirm industrial or home composting, required certification and bio-based-content claim.
Specify the roll: Provide film thickness, width, length, core, roll OD, dispenser and annual volume.
Review food-contact requirements: Define the destination market, food category, temperature and migration documentation.
Test samples: Evaluate cling, stretch, puncture, cutting, refrigeration, fogging and shelf-life performance.
Approve artwork: Confirm cutter-box design, barcode, instructions, environmental claims and certification marks.
Release mass production: Sign the product specification, approved sample, QC plan, packaging standard and delivery schedule.
Storage, Shelf Life and Export Handling
Compostable flexible films can be more sensitive to heat, moisture and prolonged storage than conventional wraps. Storage conditions and shelf life should be stated for the exact formulation, roll construction and packaging.
Keep rolls sealed in a cool, dry and clean warehouse.
Avoid direct sunlight, heaters, hot roofs and high-temperature containers.
Protect rolls from crushing, edge damage, dust and excessive stacking pressure.
Use moisture-resistant cartons and secure pallet wrapping for export.
Identify product code, gauge, width, roll length, lot and production date.
Apply first-in, first-out inventory and avoid storage beyond the approved shelf life.
Complementary Compostable Foodservice Packaging
Buyers sourcing compostable foodservice packaging may also need food-waste collection bags and PLA cold-cup lids. Food-contact approval, compostability and end-of-life acceptance must be assessed separately for each item. Certified food wrap does not make a mixed-material food pack automatically compostable.

Frequently Asked Questions
Is compostable cling film made from pure PLA?
Usually not. Pure PLA is relatively stiff and brittle. Flexible cling film commonly uses a certified blend of PLA, PBAT and other compostable components to provide stretch, softness, puncture resistance and cling.
What is the difference between compostable and biodegradable cling film?
“Biodegradable” is incomplete without a test environment and time. “Compostable” should refer to a recognized standard covering biodegradation, disintegration and compost quality under specified conditions.
Does compostable cling film break down in landfill?
Landfill does not normally provide the controlled oxygen, heat and moisture used in composting certification. The film should not be marketed as rapidly degrading in landfill or as a solution to littering.
Is industrial-compostable film also home compostable?
Not automatically. Home composting occurs at lower and less controlled temperatures. The exact finished film requires a separate home-compost certification before that claim or logo can be used.
What thickness is recommended for food cling film?
Many food-wrap projects use approximately 8–20 microns, with 10–15 microns common in market examples. The correct gauge depends on roll format, food, tray corners, puncture risk and required stretch.
Can the film wrap hot food?
Only within the validated temperature range of the exact grade. Hot food can soften the film or affect migration. Provide the maximum food temperature and contact time before approval.
Can compostable cling film be used in a microwave?
Microwave suitability should not be assumed. Use the film in a microwave only when the exact product has been tested and labeled for that use, and follow the specified venting and food-contact instructions.
Is the film suitable for freezer storage?
Suitable grades may work in freezer applications, but low-temperature brittleness, cling, puncture and thawing performance must be tested with the actual food and container.
Does compostable film provide the same shelf life as PVC or PE wrap?
Not necessarily. Oxygen and water-vapor transmission, cling, thickness and food interaction vary by polymer and formulation. A side-by-side shelf-life test is required for each application.
Can anti-fog performance be added?
An anti-fog grade may be developed or selected, subject to food-contact and compostability requirements. The film should be tested under the intended chilled-food temperature and humidity cycle.
Which certifications should buyers request?
Depending on the market, buyers may request ASTM D6400/BPI, EN 13432/Seedling, OK compost INDUSTRIAL, OK compost HOME, AS 4736 or AS 5810. Verify that the exact film grade and thickness are covered.
Is compostable cling film fully plant-based?
Not necessarily. PLA can be bio-based, while PBAT is generally fossil-derived. Compostability and bio-based content are separate claims and should be supported independently.
Can Wallis customize the roll and dispenser box?
Yes. Width, length, gauge, core, winding, slide cutter, dispenser box, artwork, barcode and export carton can be discussed according to MOQ and production feasibility.
How should compostable cling film be stored?
Store sealed rolls in a cool, dry place away from sunlight, heaters, hot vehicles and high humidity. Use first-in, first-out inventory and follow the shelf life specified for the formulation.
Can samples be tested before a bulk order?
Yes. Samples should be tested for cling, stretch, puncture, roll release, cutting, food contact, refrigeration, freezer or warm-food conditions and product shelf life.
What determines the minimum order quantity?
MOQ depends on formulation, certification, thickness, roll width, length, core, printing, cutter box, private-label artwork and whether the specification uses an existing production setup.
What information is required for an accurate quotation?
Provide food type, container, temperature, thickness, width, length, roll format, performance targets, food-contact market, compostability certification, packaging, quantity and destination.
Does compostability certification also confirm food-contact safety?
No. Compostability testing addresses defined end-of-life conditions, while food-contact approval addresses material safety for the intended food type, time and temperature. Buyers should request both sets of records for the actual finished film.
Can this film be used on automatic tray wrapping equipment?
Potentially, if a grade is suitable for the machine. Automatic equipment may require specific stretch, unwinding, sealing and roll geometry. Provide equipment details and conduct an on-machine sample trial before bulk orders.
Can Wallis offer 300 mm and 450 mm compostable cling film rolls?
These are common market widths that can be discussed for OEM supply. Availability depends on the chosen formulation, gauge, slitting capability, roll length, core and minimum order quantity.
Is biodegradable cling film the same as compostable cling film?
No. “Biodegradable” needs a defined environment and timescale, while a compostable claim should be verified to a relevant standard for a specific end-of-life system. Do not assume landfill or marine biodegradation.
