Products Description
Compostable Shopping Bags
Compostable Bags with Certification
The compostable bags are engineered for performance and planet. Unlike traditional plastic that persists for centuries, our bags are certified to break down into nutrient-rich compost in a home composting environment, leaving no toxic residues.
Advanced Material Science: Beyond
“Just Natural”
Our bags utilize a sophisticated PBAT/Corn Starch/PLA blend. This combination ensures the flexibility and durability of traditional plastic, while being fully compostable. PBAT, although petroleum-based, is designed to biodegrade completely under composting conditions, working in synergy with plant-based PLA to create a truly circular product.
Engineered for Heavy-Duty Performance
We’ve solved the common weaknesses of eco-bags with superior engineering:
Excellent Stretch & Leak Prevention: Advanced heat-sealing technology and a flexible polymer formula ensure the bag can stretch under weight without tearing and effectively contain wet or greasy waste.
Custom-Fit Sizing
Available in a wide range of sizes with custom bottom dimensions to perfectly fit standard kitchen bins and commercial containers.
Types of Biodegradable Shopping Bags by Handle
Biodegradable T-Shirt Bags
Handle & Structure: Features the classic loop handles (like a T-shirt), providing a comfortable grip for hand-carrying. Our bags are engineered with reinforced seams for superior load capacity and leak prevention.
Material Truth: Made from certified compostable polymers (PBAT/Corn Starch/PLA), They are designed to fully break down into compost in a controlled environment, leaving no toxic residues.
Best For: Retail shopping, grocery carryout, and general-purpose use where durability and comfort are key.
Biodegradable Die-Cut Handle Bags
Handle & Structure: Features a die-cut handle (a cut-out in the bag itself), creating a flat, easy-to-grip opening. This design is often more economical and suitable for lightweight retail items, apparel, and promotional events.
Material Truth: They are made from PBAT/Corn Starch/PLA blends and carry the same compostability certifications. They are not recyclable and must be directed to composting streams.
Best For: Clothing stores, gift shops, and events where a sleek, flat-handle design is preferred.
Biodegradable Drawstring Bags
Handle & Structure: Features a built-in drawstring closure (usually made of the same PBAT material). The user pulls the strings to securely cinch the bag shut, providing excellent leak and odor control. This design offers a secure, no-slip closure that is ideal for waste, laundry, or loose items.
Material & Performance: Made from our robust PBAT/PLA blend, these bags are designed for high-tensile strength to prevent the drawstring from snapping. The reinforced drawstring channel ensures durability. They are leak-proof and ideal for wetter or heavier contents.
Best For: Organic waste collection, pet waste, laundry bags, and any application where a secure, sealed closure is required for hygiene and convenience.
Handleless Compostable Bags (Flat Bags)
Handle & Structure: No handles. This category includes simple flat bags. They are designed for high-speed dispensing or as inner liners.
Material Truth: The same certified compostable material, offering a lightweight solution for single-use applications where carrying comfort is not a priority.
Best For: Point-of-sale dispensing for fruits/vegetables, waste bin liners, and primary product packaging.
Advantages of Biodegradable Shopping Bags
Lower Carbon Footprint
While traditional plastics are derived from fossil fuels, our bags utilize bio-based materials (like PLA from plant starch) that sequester carbon during growth.
Life Cycle Assessments (LCA) indicate that compostable bags generally have a lower carbon footprint compared to conventional plastics, especially when properly processed in industrial composting facilities where they break down into water, CO₂, and biomass without leaving persistent microplastics.
Waste Reduction & Circular Economy
Traditional plastics persist for centuries, clogging landfills and oceans. Our compostable bags are designed to close the loop.
In a controlled composting environment, they decompose within months, turning waste into valuable compost for soil enrichment. This significantly reduces the volume of long-lasting plastic waste and supports a circular economy model where packaging returns to the earth.
Source Reduction & Renewable Materials
Our bags are made primarily from renewable resources (such as corn starch) rather than finite petroleum. This shifts the raw material base away from fossil fuels, reducing dependence on non-renewable resources.
The manufacturing process for bio-polymers like PLA typically requires less fossil energy input compared to producing conventional plastic from crude oil.
Non-Toxic & Soil Safe
Unlike traditional plastics that can leach harmful additives (like phthalates) into the environment, our certified compostable bags are produced without toxic chemicals.
At the end of their life, they break down into harmless natural compounds that are safely absorbed by the soil, posing no threat to wildlife or ecosystems.
Applications of Biodegradable Shopping Bags
1. Retail & Grocery Carryout
Used in supermarkets, fashion stores, and retail outlets as a direct, eco-friendly replacement for conventional plastic shopping bags.
2. Lightweight Packaging & Protection
Used for packaging non-food items such as apparel, stationery, and lightweight consumer goods. Provides a protective layer while maintaining a sustainable brand image.
3. Produce & Bulk Food Handling
Handleless bags (on rolls) are widely used in fruit and vegetable sections, bakeries, and bulk food aisles. They provide a hygienic and convenient way for customers to handle loose items before checkout.
While our certified bags are ideal for organic waste,
they are not suitablefor the following scenarios:
Plastic Recycling Streams
Do NOT put them in the plastic recycling bin.Compostable bags are not recyclable. Placing them in the recycling bin will contaminate the entire batch of recycled plastic, causing issues for recycling facilities.
Hazardous Waste
Not recommended for hazardous chemicals, batteries, or construction debris. These bags are designed for organic waste (food scraps, yard waste). Heavy or sharp inert waste may puncture the bag.
Long-Term Storage
Not suitable for long-term archiving of items. As a natural product, these bags have a shelf life of approximately 12 months. They are designed to break down, not to last forever like traditional plastics.
Note on Landfills:
Like all plastics, if sent to a landfill (anaerobic environment), decomposition is severely inhibited. To realize the environmental benefits, please compost them.

FAQ
Q: How using Compostable Shopping Bags are good for the planet?
Reduced carbon footprint: By choosing biodegradable shopping bags, we can reduce our carbon footprint and help mitigate the effects of climate change.
Improved soil health: When biodegradable shopping bags break down, they release nutrients into the soil, improving soil health and fertility. This process of natural decomposition also creates a valuable soil amendment, known as compost, that can be used to grow healthy plants and reduce the need for harmful chemical fertilisers.
Q: What are the economic benefits of using Biodegradable Shopping Bags?
Reduced waste disposal costs: In some areas, municipalities charge higher fees for the disposal of traditional plastic bags due to their negative environmental impact. By using eco-friendly options, households and businesses can reduce waste disposal costs and save money in the long run.
Q: Are Compostable Shopping Bags environmentally friendly?
Q: How should I dispose of compostable shopping bags?
A: Follow this simple plan to ensure they break down properly:
1. Send to an industrial composting facility. Check with your local waste management provider. If they accept "compostable plastics" in the green/organics bin, this is the most reliable and fastest method. Our bags are certified for this process .
2. Home composting requires an active, well-managed system. This needs:
Regularly turned (for aeration).
Maintains proper moisture.
Reaches and sustains warm temperatures.
In such a system, our OK compost HOME certified bags will break down. This process is slower and less guaranteed than industrial composting.
3. If industrial composting is unavailable and you do NOT have a proper home compost system, please dispose of the bag in the general waste bin.While not ideal, this prevents the bag from contaminating plastic recycling streams or littering the environment.
Do not litter.
Do not simply bury in the garden. In cold, dry, or compacted soil, the bag will not decompose properly and may harm soil health. This method is not recommended.
Q: Can the Biodegradable Shopping Bag be reused?
Our bags are engineered for single-use performance and closed-loop circularity. While the material (PBAT/PLA) is strong, it is designed to degrade over time.
Material Science: Repeated folding, washing, or stress will accelerate the degradation process, compromising the bag's integrity and increasing the risk of leakage.
Hygiene: These bags are typically used for laundry, pet waste, or damp items. Reusing them poses hygiene risks and is not advised.
Best Practice: Use once, then dispose of in a commercial composting facility to complete the sustainable cycle.
Q: Are biodegradable shopping bags durable?
1. Strength Comparable to Conventional Plastic
Our compostable bags are not the fragile, “earthy” bags of the past. Through advanced material science, we achieve:
High Load-Bearing Capacity: Our standard T-shirt bags can carry 6-8 kg of groceries safely, thanks to reinforced seams and star-seal bottoms.
Superior Tensile Strength: The PBAT polymer provides excellent elongation and puncture resistance, preventing rips during use.
2. Performance Tailored for Specific Uses
Durability is application-specific. We offer a range of thicknesses and formulations:
Retail Bags: Balanced strength for everyday shopping.
Heavy-Duty Drawstring Bags : Extra thickness for wet organic waste or heavier items, featuring a reinforced drawstring channel to prevent snapping.
3. Key Factors Ensuring Durability
The strength of a compostable bag depends on:
Material Purity: Using certified, high-molecular-weight resins (not cheap fillers).
Manufacturing Process: Our blown-film extrusion process ensures consistent thickness and material integrity.
Important Note on Limitations
While durable in use, compostable bags have a shorter functional lifespan than conventional plastic. They are designed to begin breaking down under specific composting conditions (heat, moisture, microbes). This is a feature, not a flaw. For long-term storage (over 12 months), we recommend conventional plastic or specific archival-grade solutions.
