Tomato Sauce Packaging faces unique hurdles:

▶ PH 3.5-4.5 acidity accelerates material degradation

▶ Lycopene oxidation causes 18% color loss in 60 days (USDA data)

▶ Thermal processing (e.g., 85°C hot-fill) demands structural stability

Next-Gen Tomato Sauce Packaging: 360° Protection for Flavor & Freshness

Engineered for acidic condiments needing 12+ month shelf life

High Barrier Acid Resistant Ketchup Pouches｜PET/VMPET/PE COMPOSITE FILM｜Extended Shelf Life 12 Months

Core Features & Material Innovation

1. Triple Defense Barrier System

PET/VMPET/PE Composite Structure

• Layer 1 (External): 12μm PET - UV blocking（Light transmission <3%）

• Layer 2 (Barrier): 9μm VMPET - OTR 0.5 cm³/m²·24h (5x better than BOPP)

• Layer 3 (Sealant): 80μm PE - Acid-resistant (PH 3 verified by GB 4806.7)

2. Chemical Stability Guarantee

PH3 Simulation Test Data:

Test Cycle	Material Weight Loss	Lycopene Retention
90 days	0.02%	≥94%
180 days	0.05%	≥89%

3. Production-Ready Performance

High-Speed Filling: Compatible with 300ppm rotary machines

Seal Integrity: Heat seal strength ≥30N/15mm (tested @145℃/0.5s)

Sustainability: 85% recyclable via MEPS（Monolayer PE Stream）

Technical Comparison: Outperforming Market Alternatives

Parameter	This Solution（PET/VMPET/PE）	Competitor A（BOPP/VMPET/PE）
OTR (cm³/m²·24h)	0.5	1.2
Acid Resistance Cycles	50+	32
Thickness (μm)	80-100	115

A retail study shows: Switching reduces product returns by 41% (oxidation claims).

Critical Application Scenarios

1. Hot-Fill Processing (85-90°C)

▶ 0% delamination after 3x thermal shock tests (-20℃↔40℃)

2. E-Commerce Drop Tests

▶ Certified for 1.8m vertical drops (ISTA 3A compliant)

3. UV Exposure Protection

▶ Lycopene preservation: 91% vs. 67% in clear films (60-day sunlight sim)

4. Recyclability Compliance

▶ Meets EU Single-Use Plastics Directive (SUP) thresholds

5. Print Durability

▶ Water-based inks withstand 50+ rinses (no label peeling)

Certifications & Validation

✅ Global Standards: FDA 21 CFR 177.1520, EU 10/2011

✅ Third-Party Testing:

Dyne Testing: Oligomer migration <0.01μg/dm²

SGS Reports: Burst pressure ≥0.35MPa

✅ Client Case:

Brand X achieved 18-month shelf life with zero preservatives
