Compostable Paper Bags for Private Label & OEM Supply
Engineered for leak resistance, strength and consistent large-volume supply for supermarkets, distributors and commercial packaging programs.
72HR Leak-Resistant
A reinforced waterproof base holds liquid for 72 hours with zero seepage — verified in stress testing. Built for produce, deli and food-retail use where moisture is constant.
Reinforced Strength
Tested to a 10 kg+ static load with no structural failure at the handles or base. Carries real grocery weight, not just spec-sheet weight.
Moisture & Grease Resistance
A barrier layer resists moisture and grease without the tackiness or melting seen in bio-plastic film — stable across normal retail and food-handling conditions.
OEM & Private Label Ready
Custom sizes, print and branding, produced under your label with full certification and batch documentation included.

Test Reports
I. Technical Comparison: Guarden Reinforced Paper vs. Standard.
FilmTechnical auditors and procurement teams prioritise structural performance. The matrix below shows the engineering difference:
| Feature | Guarden Reinforced Paper | Standard Compostable Film (PLA/PBAT) |
|---|---|---|
| Primary Material | FSC Certified Kraft Paper + Waterproof Barrier | Bio-based Film (Cornstarch-based) |
| Wet Strength | High; maintains 3D shape when saturated | Low; stretches and thins when wet |
| Puncture Resistance | Resists sharp bones and shells | Easily pierced by hard organic waste |
| Max Static Load | Tested up to 10kg+ | Typically fails at 3-5kg |
II. The Data: Stress-Test Results
We pushed our bags to the limit. The parameters below are verified for consistent performance across North American retail and food-handling conditions.
| Test Category | Testing Parameter | Environment Condition | Result & Conclusion |
|---|---|---|---|
| 72-Hour Leak-Proof | 500ml Liquid (Water/Milk) | Ambient Temp (22°C) | Zero Seepage. The reinforced base showed no moisture penetration after 72 hours. |
| 10kg Strength Test | 10kg Solid Iron Dumbbell | Vertical Static Load | No Structural Failure. Handles and base remained intact under 10kg+ weight. |
| High-Velocity Puncture Test | Corkscrew-style Wine Opener (Steel) | Vertical Drop (3X) from 30cm height | ZERO PUNCTURES. No piercing of the multi-layer base or wall after three impacts. |
| Heat Stability | High Humidity / Temperature | 35°C+ Simulation | Stable. Paper does not become "tacky" or melt like bio-based film. |
Performance Summary & Technical Verdict: Based on verified stress-test data, Guarden's reinforced paper bags are engineered for demanding retail use. The high-velocity puncture test confirmed zero piercing from a steel wine opener dropped three consecutive times. Combined with a 10 kg+ static-load capacity and a 72-hour leak-resistant base, Guarden significantly outperforms standard compostable film liners — the stronger choice for grocery, produce and food-retail programs.
