Custom Compostable PLA-Based Flexible Packaging Film Roll
Wallis custom compostable PLA-based flexible packaging film is developed for brands, packaging converters and product manufacturers seeking transparent or colored rollstock for food packaging, produce bags, bakery packs, apparel bags, retail overwrap and other validated flexible-packaging applications. The film can be supplied in customized widths, thicknesses, reel lengths, core sizes and converting formats.
High-performance compostable packaging film is usually produced from a certified blend of compostable polymers that may include PLA, PBAT and other application-specific components. PLA can contribute clarity and bio-based content, while flexible polymers improve elongation, toughness, sealability and machine performance. The final formulation—not one resin name—determines the film's mechanical, optical, barrier and compostability properties.
This page is positioned for compostable flexible packaging rollstock, not ordinary household cling film. Projects should define the packaging machine, sealing method, product type, storage conditions, required barrier, print process, certification and finished-pack format before material approval.

What Is Compostable Flexible Packaging Film?
Compostable flexible packaging film is a thin rollstock material designed to protect, contain or present products while meeting a recognized compostability standard under specified conditions. Depending on the grade, the film may be used as a standalone monofilm, a sealant layer in a compostable laminate or a converting film for bags and pouches.
Flexible Polymer Blend Instead of Pure PLA
Pure PLA is transparent but relatively stiff and brittle for many flexible-packaging processes. Commercial compostable films often combine PLA with flexible compostable polymers and modifiers to achieve usable elongation, puncture resistance, sealing strength, coefficient of friction and roll handling.
Designed for Converting and Packaging Machinery
The film may be converted through printing, slitting, heat sealing, bag making, horizontal flow wrapping or vertical form-fill-seal equipment. Machine compatibility should be verified with the actual line because sealing temperature, dwell time, tension, friction and web stiffness differ from conventional PE or PP films.
Certification Applies to Specific Film Structures
Industrial or home-compostability certification applies to defined material codes, thicknesses, colors, inks, adhesives and structures. Certification of a resin pellet does not automatically cover every printed film, laminate or finished package.

Film Formats for Packaging Converters
| Format | Typical Use | Critical Specification |
| Unprinted Rollstock | Printing, lamination, bag making and downstream conversion | Dyne level, thickness profile, slip, winding and splice policy |
| Printed Rollstock | Brand packaging on HFFS, VFFS or flow-wrap machinery | Repeat length, eye mark, color tolerance, print direction and registration |
| Center-Folded Film | Bag making, overwrap and garment or product covers | Fold position, lay-flat width, edge alignment and blocking |
| Tubular Film | Bag conversion and sleeve applications | Lay-flat width, gusset, tube uniformity and sealing orientation |
| Laminating / Sealant Film | Compostable barrier laminates and printed flexible packs | Bond strength, seal initiation, hot tack and certified adhesive system |
Key Packaging Performance Requirements
Tensile Strength and Elongation
The film must tolerate web tension, forming shoulders, bag opening and product handling without uncontrolled stretching or breakage. Tensile and elongation targets should be specified in both machine and transverse directions.
Puncture and Impact Resistance
Product edges, stems, frozen food, apparel hardware and packing equipment can puncture thin films. Dart impact, puncture energy and actual-pack drop tests should be considered when selecting thickness and structure.
Heat Sealing and Hot Tack
A usable sealing window is essential for automated packaging. Buyers should test seal-initiation temperature, dwell time, pressure, seal strength, hot tack, contamination tolerance and jaw-release behavior on the intended machine.
Coefficient of Friction and Anti-Blocking
Surface friction affects unwinding, forming, product loading and finished-bag handling. Excessive slip can create tracking problems, while excessive blocking can prevent bags or film layers from separating. COF requirements should be defined by the converter.
Transparency, Gloss and Haze
Clear packaging should be approved for haze, gloss, tint, gels, black spots, die lines and optical distortion. A highly transparent grade may use a different film structure or production process from a general-purpose compostable bag film.
Barrier and Product Shelf Life
Oxygen and water-vapor barrier vary by material and thickness. Single-ply compostable film may suit breathable produce or short-shelf-life goods, while dry, oily or aroma-sensitive products may require a certified compostable laminate. OTR and WVTR targets should be based on a shelf-life study.

| Apparel and Retail Products | Transparent or printed garment bags, overwrap and product sleeves | Clarity, tear, static, ventilation holes, closure and transport |
| Mailers and E-Commerce | Opaque or printed film with adhesive closure | Tear, puncture, seal, adhesive compatibility and privacy |
Printing and Branding Options
Compostable film can support custom branding when the surface treatment, ink, drying or curing process and final compostability assessment are compatible. Printed rollstock should be approved using physical proofs because film transparency, white ink, reverse printing and lamination can change the final appearance.
| Artwork | Editable AI or print-ready PDF with dieline, repeat length, bleed and barcode |
| Print Direction | Surface or reverse print, inside/outside winding and eye-mark orientation |
| Color Control | Pantone references, white ink, transparent ink, color tolerance and approved printed sample |
| Environmental Claims | Certification logo, disposal instructions and certificate code only when authorized |
| Traceability | Batch code, production date, material code and customer SKU where required |
Machine Compatibility and Packaging Trials
Define the machine: Provide machine type, model, maximum reel width, core, roll OD, speed and web path.
Confirm the package: Supply the dieline, bag dimensions, seal type, product weight and target output rate.
Review film handling: Test unwind, tracking, tension, static, friction, forming and cutting.
Develop the seal window: Evaluate temperature, pressure, dwell, seal strength and hot tack.
Run product trials: Pack the actual food or product and complete leak, drop, transport and shelf-life tests.
Approve printed rollstock: Confirm registration, color, eye marks, print direction and repeat length.
Lock the specification: Record grade, thickness, width, winding, splices, QC limits and pallet standard.
Food-Contact and Regulatory Requirements
Compostability does not replace food-contact compliance. For food packaging, the exact film, additives, inks, adhesives and use conditions should comply with the destination market's requirements.
Identify food type, direct-contact side, temperature and contact duration.
Define aqueous, acidic, alcoholic, dairy, dry or fatty-food simulants.
Request overall and specific migration documentation where applicable.
Include printing inks, adhesives, coatings and anti-fog additives in the review.
Evaluate odor, taste and product interaction for sensitive foods.
Do not extend one certificate to different structures, thicknesses or production sites without verification.
Industrial Compostability, Home Compostability and Bio-Based Content
| Claim | Correct B2B Interpretation |
| Industrial Compostable | Intended for controlled commercial or municipal composting under standards such as EN 13432 or ASTM D6400 |
| Home Compostable | Requires separate certification for lower-temperature home-compost conditions |
| Biodegradable | Incomplete unless environment, test method and time are stated |
| Bio-Based | Describes renewable carbon content and is separate from compostability |
| Landfill, Soil or Marine Degradation | Not automatically covered by compostability certification and should not be claimed without specific testing |
Buyers should verify the finished film in the relevant certification database and confirm the permitted thickness, printing, color and logo use. Local composting facilities may still reject flexible film, so collection-system acceptance is essential.
Comparison with Conventional PE and PP Packaging Films
| Factor | Compostable Film | PE / PP Film |
| End-of-Life | Certified composting where accepted and properly collected | Recycling potential depends on format, cleanliness and collection infrastructure |
| Machine Setup | May require different tension, heat and speed settings | Established settings on most packaging machinery |
| Heat Resistance | Grade-specific and often more heat-sensitive | Wide range depending on polymer and structure |
| Barrier | Single films may be breathable; laminates can provide higher barrier | Broad range of established high-barrier structures |
| Commercial Approval | Both require actual machine trials, package testing, shelf-life evaluation and regulatory review |

Storage, Shelf Life and Export Packaging
Compostable films can be sensitive to prolonged heat and humidity. Storage conditions, shelf life and transport protection should be defined for the exact formulation and reel size.
Store sealed reels in a cool, dry and clean warehouse.
Keep away from direct sunlight, heaters, hot roofs and high-temperature containers.
Protect reel edges, cores and surfaces from impact, dust and moisture.
Use suspended or palletized roll packing appropriate to reel weight and width.
Identify grade, thickness, width, length, batch, winding direction and production date.
Apply first-in, first-out stock management and re-test aged film before critical production.
Complementary Compostable Packaging Products
A complete compostable packaging program may combine rollstock with certified bags, trays, labels, cups, lids, cutlery or straws. Each component must be assessed independently, and the complete package should meet the required food-contact, mechanical and compostability conditions.

Frequently Asked Questions
Is compostable packaging film made from pure PLA?
Usually not. Pure PLA is relatively stiff. Flexible packaging films commonly use certified blends or co-extruded structures containing PLA and flexible compostable polymers to provide elongation, toughness and sealability.
What is the difference between packaging film and cling film?
Cling film is a finished wrap designed to adhere around food or containers. Packaging film rollstock is a broader material category used for printing, sealing, bag conversion, flow wrapping and automated packaging.
What thickness is available?
Many single-ply compostable packaging films fall within approximately 15–80μm. The correct thickness depends on the structure, product weight, puncture risk, machine and certification scope.
Can compostable film run on standard packaging machines?
Suitable grades can run on conventional equipment, but web tension, friction, sealing temperature, dwell time and speed may need adjustment. A machine trial is required before bulk conversion.
Can the film be printed?
Yes, when the surface treatment, ink and curing system are compatible. The printing system must also remain within food-contact and compostability requirements for the finished package.
Is the film heat sealable?
Heat-sealable grades are available subject to structure. Seal initiation, strength, hot tack and machine settings should be tested using the intended package and product.
Can it be used for food packaging?
Yes, when the exact film, inks, adhesives and use conditions comply with the destination market's food-contact requirements. Provide food type, temperature and contact time for document review.
Does compostable film provide a high oxygen and moisture barrier?
Barrier varies by grade and structure. Breathable monofilm can suit produce, while dry food, snacks or aroma-sensitive products may require a compostable high-barrier laminate.
Is the film suitable for frozen products?
Suitable low-temperature grades can be evaluated. Freezer approval requires testing for brittleness, puncture, impact, seal strength and freeze-thaw cycling.
Is industrial-compostable film also home compostable?
Not automatically. Home composting occurs at lower and less controlled temperatures. The exact film structure requires separate home-compost certification before that claim can be used.
Does the film biodegrade in landfill or the ocean?
Compostability certification does not prove rapid degradation in landfill, soil or marine environments. Claims outside the certified composting environment require separate testing.
Is compostable film fully bio-based?
Not necessarily. Some flexible compostable polymers are fossil-derived. Bio-based content and compostability are different attributes and should be supported by separate evidence.
Can Wallis supply custom colors and opaque film?
Transparent, tinted, white and opaque options can be discussed. Pigments and masterbatch must be compatible with the required mechanical, food-contact and compostability specifications.
What reel information is required?
Provide width, length, core ID, maximum roll OD, maximum weight, winding direction, splice allowance and machine-unwinder details.
Can samples be tested before a bulk order?
Yes. Samples should be evaluated for printing, web handling, sealing, bag conversion, puncture, drop performance, barrier and product shelf life.
What determines the minimum order quantity?
MOQ depends on film grade, thickness, width, color, printing, laminate structure, certification and whether the order uses an existing production specification.
What information is needed for an accurate quotation?
Provide the product, package type, machine, film structure, thickness, reel dimensions, print, barrier, seal, certification, quantity, destination and delivery date.
