Breaking the Industry Dilemma: Traditional Dog Food Bags Fail to Block Oxygen and Are Hard to Recycle? Triple Innovation in Same-Material High-Barrier Dog Food Bags Redefines New Standards

Soul-Searching Question: Why Do High-End Dog Foods Always Fail at the Packaging Stage?

· "Imported dog food starts to smell rancid after just half a month? Is eco-friendly packaging always sacrificing freshness performance?"

The Irreconcilable Contradictions of Traditional Composite Material Packaging

❶ Barrier vs. Environmental Protection: Aluminum foil/PET composite films are hard to recycle, while recyclable films have a steep drop in oxygen barrier performance.
❷ Hidden Cost Trap: Return rates due to oxidation spoilage exceed 18%, resulting in billions of dollars in annual losses in the high-end market.
❸ International Compliance Risks: With the EU SUP directive taking effect, composite packaging containing EVOH/PET faces hefty carbon tariffs.

Technical Breakdown of Same-Material High-Barrier Dog Food Bags: A Unified Solution

1. Omnidirectional Oxygen Barrier Matrix: EVOH Core Layer + 5G Molecular Topology

☛ Multi-Layer Co-Extrusion Symmetrical Structure (MDOPE/EVOH/BOPE/PE)

· Central 12μm EVOH Oxygen Barrier Layer: O₂ Transmission Rate ≤ 0.5cc/m²·day (achieving aluminum foil-level barrier performance).

· BOPE Biaxially Oriented Layer: Puncture resistance exceeding 50N, preventing bag breakage and air leakage during transportation.

· Lab-Verified Performance: After 365 days of static testing, the acid value of coarse-grain freeze-dried food increased by only 0.2mg/g (national standard limit: 3).

2. Homogeneous Heat-Sealing Technology: Zero Layer Separation for Full Recycling

· All-PE Heat-Sealing Layer (with Compatibility Agent): Heat-sealing strength ≥ 25N/15mm.

· Chemical Recycling Compatibility: EVOH purity > 99% extracted via dissolution-precipitation method.

· Certified Sustainability: Passed GRS (Global Recycled Standard) certification, reducing carbon footprint by 37%.

3. Lightweight and Carbon-Reduction Design: Reverse Optimization of Comprehensive Costs

· Thickness Reduced by 28% (120μm → 88μm): Saves 2,400 tons of raw materials annually for a production scale of 10,000 tons.

· No Composite Process Required: Reduces production line energy consumption by 45%, lowering overall packaging costs by 19%.

Performance Validation Across Four Scenarios

Scenario 1: Anti-Oxidation Challenge for High-Fat Dog Food (Tested with Real Formulas from Orijen & Acana)

· Accelerated Aging Test (40℃/75% RH):
▸ Peroxide Value Increase: Traditional PE bags reached 5meq/kg → Same-material bags only 0.8meq/kg.
▸ Customer Feedback: Complaint rate dropped from 22% to just 1.3%.

Scenario 2: Cross-Border Transportation of Freeze-Dried Raw Pet Food

· -18℃ Freezing Test for 12 Months:
▸ No Bag Breakage or Crystallization: Rehydration rate maintained at 98.3% (vs. 85% for ordinary bags).
▸ Real-World Test (USA to China by Sea): Moisture activity change < 0.02.

Scenario 3: Building a Sustainable Brand

· Case Study: European Organic Pet Food Brand
▸ After Carbon Label Certification: Premium pricing ability increased by 27%.
▸ Green Supermarket Placement: Reduced time to enter Whole Foods and other eco-labeled retailers by 60%.
