Looking for a reliable supplier of 45 gallon compostable trash bags?
ORIZON has manufactured compostable bags since 2009, with an approximately 20,000 m² total manufacturing site, 16 production lines and approximately 500 metric tons/month production capacity.
45 gallon compostable trash bags can be manufactured using PBAT / PLA- and starch-based compostable formulations. The final specification should be selected according to bag dimensions, thickness, seal structure, waste type and handling requirements.
The 45 gallon compostable garbage bags are produced using plant-based biodegradable materials such as PLA and PBAT, ensuring reliable strength for heavy waste loads while meeting internationally recognized compostability standards.
These bags are commonly used for contractor waste, landscaping debris, large facility waste bins, and municipal compost programs.

|---|---|
| Capacity | Approx. 45 Gallon |
| Liter Equivalent | Approx. 170 L |
| Typical Dimensions | Around 40 × 48 in, or custom |
| Thickness | Typically 22–40 μm, depending on application |
| Seal Type | Star seal / flat seal or project-specific |
| Film Colour | Natural / green / custom |
| Printing | Plain / custom |
| Packing | Roll / flat pack |
| MOQ | Typically from approx. 500 kg per specification or design |
Dimensions, thickness and seal structure should be confirmed against the actual bin, waste type and handling requirements before production.

Material & Film Specification
ORIZON 45 gallon compostable trash bags can be manufactured using PBAT / PLA- and starch-based compostable formulations.
The finished-bag specification should be selected according to:
- bag dimensions;
- film thickness;
- seal structure;
- expected waste type;
- handling conditions;
- film colour;
- printing; and
- destination-market requirements.
Film thickness alone does not determine puncture, tear, sealing or carrying performance. These characteristics should be evaluated on the final finished-bag specification.
Compostability certification should also be reviewed at the finished-product level rather than inferred from the material formulation alone.
Compostability Certification & Documentation
Compostability certification for 45 gallon trash bags should be reviewed against the actual finished-product specification.
Relevant technical standards may include:
- ASTM D6400
- EN 13432
- AS 4736
- AS 5810
Third-party certification programs and conformity marks may include those administered by:
- BPI
- TÜV AUSTRIA
- ABA
- DIN CERTCO
TÜV AUSTRIA Scope
ORIZON’s current OK compost INDUSTRIAL and OK compost HOME certificates by TÜV AUSTRIA state the Product Types:
“Bags for collection of biodegradable refuse”
“Shopping bags (check-out bags)”
The current OK compost INDUSTRIAL certificate has a maximum nominal thickness of 78 μm, while the current OK compost HOME certificate has a maximum nominal thickness of 63 μm.
A specific 45 gallon trash bag must still be reviewed against the applicable current certificate conditions, product classification and final finished-product specification.
Relevant variables may include dimensions, thickness, material formulation, film colour, printing, ink, additives, seal structure and other finished-product components.
Certification or conformity marks should only be used where the applicable certification scope and mark-use authorization requirements have been confirmed.
Typical Applications
45 gallon compostable trash bags are widely used in environments where large waste volumes are generated.
Common applications include:
- construction and contractor waste
- landscaping and yard waste
- commercial building maintenance
- large event waste collection
- municipal compost and waste programs
Because of their large capacity, these liners are often used for heavy-duty waste collection in commercial facilities.

FAQ
They can be specified for large commercial and facility waste applications. The appropriate thickness and seal structure should be selected according to the waste type and handling conditions. Heavy, sharp or irregular waste should be evaluated separately.
A 33 gallon bag provides approximately 125 L of nominal capacity, while a 45 gallon bag provides approximately 170 L. Actual compatibility should be confirmed against the bin dimensions rather than capacity alone.
Acceptance varies by municipality, waste-service provider and receiving facility.
Compostability certification does not automatically establish acceptance by a particular local organics or composting program.
Buyers should confirm both the applicable finished-product certification and local program requirements.
