Material & Print Quality
Substrates
● Basic: 15-50μm monolayer HDPE/LLDPE (for simple logos).
● Premium: Coextruded/laminated PE + print-receptive films (e.g., 20μm BOPP) for vivid, photorealistic designs.
Print Capabilities
● 3-8 color printing at 120-180 LPI resolution.
● Solvent-based inks (500+ rub cycles for industrial use) or water-based inks (FDA 21 CFR 175.300 compliant for food contact).
Structural Strength
● Block bottom: Heat-sealed for stable pallet stacking.
● Lamination bond: ≥3.5N/15mm peel strength (per FINAT FTM 1) to prevent layer separation.
● Stacking: 5-tier stacking possible with 100mm gussets (25kg payloads).
Why Choose Our Gravure Printing PE Square Bottom Bags?
● Durable Prints: Ink resists abrasion (≤5% wear after 200km transport), UV fading (ΔE ≤2.0 after 500hr exposure), and chemical exposure (no transfer in pH 2-12 solutions).
● Protective Barriers:
PE/BOPP: Low water vapor transmission (0.8g/m²/24hr) – great for hygroscopic materials.
PE/foil: Superior oxygen barrier (≤0.3cc/m²/day) – extends freshness (e.g., coffee beans last 40% longer).
Cost-Effective: Ideal for large runs (20,000+ units) – 60% lower decoration cost than digital printing.
Efficiency: Compatible with high-speed VFFS machinery (200m/min) and integrated QR codes for fast traceability.
