Certified Compostable

Certified Compostable

Kraft/PLA and cellulose builds that return to soil within 180 days.

Verified Claims
  • Seed logo (EN 13432 / AS 4736) for industrial composting
  • AS 5810 + TUV OK Compost HOME for home-compostable structures
  • Barrier caps at ~70% of aluminium foil
  • 60-150 um total thickness across duplex to quad structures
Limits
  • -Not suitable for products with 6+ month shelf life or high fat content
  • -Kraft/PLA = industrial only; cellulose = home-compostable niche
  • -BPI logo sublicense ~$3,000/yr — flagged before artwork

Recyclable Mono-PE

Recyclable Mono-PE

Single-polymer structures that enter the #4 store drop-off stream whole.

Verified Claims
  • Single PE polymer throughout — no delamination contamination
  • Store drop-off #4 stream: "Recyclable where facilities exist"
  • 100-200 um total, OTR <8 to <1 cc/m2/day with metallised option
Limits
  • -Not curb-side recyclable in most municipalities
  • -Mid barrier — protects for months, not a year
  • -Not compostable — would contaminate the compost stream

Bio-PE (Sugarcane)

Bio-PE (Sugarcane)

Same PE molecule, renewable carbon. Tested, printed, recyclable #4.

Verified Claims
  • Bio-based polyethylene from sugarcane ethanol
  • ASTM D6866 tested bio-based percentage on every spec sheet
  • Drop-in replacement for fossil PE — same seal strength
Limits
  • -Not compostable — it is PE, we will not let artwork imply otherwise
  • -"Bio-based" is not "biodegradable" — different axes
  • -Must use RECYCLABLE logo, never compostable markings

Verified Claims
  • GRS 4.0 certified chain-of-custody from collection to film
  • 30-90% recycled content depending on structure
  • Full range: 100-200 um, OTR <2000 down to <0.3 cc/m2/day
Limits
  • -Recycled-content claim, not recyclable — different axes
  • -Batch-to-batch colour variation inherent in feedstock

No Greenwashing

Claims we will not print — and why.

ClaimWhat we actually mean
100% compostableOnly if certified (EN 13432 / AS 4736 / AS 5810). Kraft/PLA is industrial only.
BiodegradableUnregulated term in most markets. We refuse to print it.
Eco-friendlyMarketing phrase. Every material has an environmental cost.
RecyclableOnly true if #4 PE facilities exist in your customer's area.
Made from plantsBio-PE is from sugarcane but it is still PE. It recycles as #4.
Zero plasticCompostable films contain bioplastics (PLA, PBAT, cellulose).
