Material: PBAT + PLA + Starch-Based Biodegradable
Our compostable mailers use a proprietary blend of PBAT (polybutylene adipate terephthalate), PLA (polylactic acid), and starch-based biodegradable materials. This combination delivers:
- Full compostability in both industrial (58-60°C) and home (25-30°C) conditions
- No plasticizers, heavy metals, or fluorescent agents
- Comparable seal strength and durability to traditional PE mailers
- 12-18 month shelf life when stored properly
Dual Compostability: Not all “compostable” bags work in home compost. Products certified for industrial composting only will not degrade in your backyard. Ours work in both.
Performance Data: Load Capacity / Drop Test / Burst Rate
Load Capacity: Up to 12kg Per Bag
The myth that eco-friendly materials mean weak load capacity is exactly that—a myth. Our 120μm compostable mailers tested at 12kg load capacity, matching traditional PE mailers. For apparel, cosmetics, and small electronics packaging, our 70μm option handles 6-8kg with ease.
Drop Test: 10 Falls from 1.2m Without Rupture
Tested per ISO 2248 standard: 60% of rated load, seal area impacts first. After 10 consecutive drops, our compostable mailers showed zero rupture or seal failure. Need custom testing? We conduct tests based on your actual product weight and shipping routes, with formal reports available.
Burst Rate: <0.3% on Batch Shipments
This isn’t lab-test data—it’s 24-month batch shipment statistics. Industry average: 1%-2%. Our secret:
- Every raw material batch verified (biobased content, heavy metals)
- Inline thickness monitoring during extrusion (±5% per meter)
- Ultrasonic seal welding—stronger than heat press
- 100% inspection before shipment, not sampling
Customization: Thickness / Size / Printing / MOQ
Thickness Selection Guide
Don’t just chase the lowest price—thin bags mean higher damage rates, thick bags mean unnecessary cost. Our sales team analyzes your product weight distribution to recommend the optimal thickness and help calculate total cost of ownership.
Printing Options
Flexographic Printing (Most Popular)
- Water-based ink, eco-friendly and non-toxic
- 133 lines/inch resolution—Clearly Display the Logo, gradients, fine text
- Best for large-area designs
- Ideal for orders under 5,000 pieces
Gravure Printing
- 175 lines/inch—premium brand choice
- Higher plate costs, best for 5,000+ orders
No-Print Kraft Paper Option
- No ink contamination risk
- Natural appearance, high brand recognition
- One Australian organic skincare brand saw consumer eco-approval ratings rise significantly after switching
MOQ Policy
New buyers: Start with samples. One Nordic home goods brand started with just 500 pieces. After collecting user feedback, they found the “eco story” of compostable packaging became a standout unboxing experience—repeat purchase rate increased by 12%.
- In-stock blank: 500 pieces (mixed orders allowed)
- Blank + custom logo: 2,000 pieces
- Full custom: 5,000 pieces
International Certifications — Verify Online
Triple Certification: USDA · TUV Austria · Australian BAU
Export to North America, EU, or Australia—different markets have different certification requirements. Our compostable mailers carry all three certifications, one order covers three major markets, no additional certifications needed.
- USDA Biobased Certification (USA) — Issued by US Department of Agriculture, biobased carbon content verified by third-party lab
- TUV Austria Industrial Compost Certification (EU/Australia) — Corresponds to EN13432, one of the world’s strictest standards
- Australian BAU Certification — Meets local ecological requirements, smooth entry to Australian market
Certificate Verification Online
Worried about suppliers using fake certificates? Every batch ships with a unique certificate number—verify directly on USDA, TUV, and Australian certification body websites.
Why certificate fraud is high-risk: If destination country customs finds the certificate doesn’t match the goods, fines are just the start—brand reputation damage is the real cost.
Industrial vs Home Compost Compatibility
Industrial Compost
Temperature: 58-60°C
Cycle: 90-180 days
Standard: EN13432 / TUV
Home Compost
Temperature: 25-30°C
Cycle: 180-365 days
Standard: AS5810 / Home Compost
Biodegradable vs Compostable vs Home Compostable
These three terms are misused interchangeably, but the differences are critical. Choosing wrong can get your products blocked at customs.
EU Regulation: Since 2021, the EU has restricted vague terms like “biodegradable” on packaging—specific degradation conditions and timeframes must be stated.
Market-Specific Recommendations
USA Market → USDA + TUV dual certification recommended. Amazon US has internal compostable packaging audit standards—products without certification risk removal.
EU Market → EN13432 is the threshold. 180-day industrial composting test required, with biogenic carbon content >50%. Heavy metals must meet 94/62/EC directive (lead, mercury, cadmium, hexavalent chromium total <100ppm).
Australian Market → BAU certification is mandatory, requires both AS4736 (industrial) and AS5810 (home compost) standards. Customs procedures are complex—allow extra clearance time.

FAQ
Q1: How much more expensive are compostable mailers vs regular plastic?
Compostable material cost is 1.5-2.5x regular PE. But don’t just look at unit price—one skincare brand reported 8% increase in repeat purchases after switching to compostable packaging. Brand premium and consumer goodwill far outweigh the additional packaging cost.
Q2: Does degradability decrease over time?
Regular products have 12-18 month shelf life. Storage: cool and dry, temperature <25°C, humidity <60%. We offer exchange service for expired inventory.
Q3: How do we guide consumers on correct disposal?
Print usage instructions inside the mailer or add diagrams on your product page. Be specific: “Place in home compost bin” or “Take to industrial composting facility.” Specific disposal instructions build more consumer trust than vague “degradable” claims.
Q4: Can you provide FDA or EN13432 test reports?
Yes. Every shipment includes batch-specific test reports. For specific market access tests (FDA food contact evaluation, etc.), we can connect you with third-party labs—client covers costs, 2-4 week turnaround.
Q5: What payment methods do you accept?
First order: 30% deposit, balance before shipment. Clients with annual purchases >500,000 RMB: up to $500,000 credit line, 30-day terms. Credit approval requires company registration documents and credit history.
Q6: What if quality issues are found?
7 business day quality guarantee: Rupture, seal defects, or size deviation >5%—no conditions. We reship or refund within 3 business days of confirmation, with return shipping covered.
Q7: Do you provide competitor analysis or selection guidance?
Free. Provide your target market, sales platform, product category, and target customers. Our technical team delivers complete proposals—including competitor analysis, spec recommendations, and price estimates—within 1 business day.
