Material Structure | Multi-layer composite (e.g., PET/AL/PE, BOPP/CPP, OPP/PE) with customizable barrier layers for oxygen/moisture protection | |
Primary Function | High-definition 10-color gravure printing for vibrant branding; tailored designs for energy bar packaging (e.g., protein bars, meal replacements) | |
Barrier Technology | Optional aluminum foil (7–12 µm) or metallized layers for UV/oxygen blocking; extends shelf life up to 12 months | |
Seal Integrity | Heat-sealable inner layer (PE/CPP) ensures leak-proof seals for powders/liquids; withstands filling temperatures up to 150°C | |
Surface Treatment | Anti-static coating (≤10⁹ Ω/sq) prevents sugar/protein powder adhesion during high-speed filling | |
Print Quality | 10-color rotary gravure printing with ≤0.1mm registration accuracy; supports Pantone color matching & complex graphics | |
Certifications | FDA 21 CFR, ISO 22000, BPA-free; recyclable/biodegradable variants available (e.g., PLA/PBAT) | |
Sustainability | Recyclable PET/PE structures; EN13432-certified PLA options with 180-day decomposition | |
