Product Description:
Our Food Grade Multi-Layer Powder Packaging Roll Film is specifically engineered for premium protection of milk powder, coffee, and other powdered food products. Constructed with a high-performance multi-layer composite structure, this roll film combines superior barrier properties, mechanical strength, and food safety compliance to preserve product quality, flavor, and nutritional value over extended storage and transportation.
The advanced laminate structure typically includes layers such as PET for clarity and tensile strength, EVOH or AL for ultra-low oxygen and moisture permeability, and PE for heat sealability and puncture resistance. This design effectively shields powders from moisture, oxygen, light, and external odors, preventing clumping, oxidation, and flavor degradation. The film’s smooth inner surface ensures easy powder flow during filling, while its robust outer layers resist abrasion and punctures, maintaining integrity in challenging supply chain environments.
Designed for compatibility with automatic packaging machines, the roll film offers precise tension control and consistent performance for high-speed production. It supports vibrant, high-resolution printing for brand differentiation, with options for matte/gloss finishes and special effects. Customizable in thickness, width, and layer composition, our solution adapts to your specific packaging requirements—whether for infant formula, gourmet coffee, nutritional powders, or other dry food products.
Product Parameters
| Attribute |
Description |
| Material Composition |
Multi-layer composite (e.g., PET/AL/PE, PET/EVOH/PE, or custom formulations) – food-grade materials compliant with FDA, EU 10/2011, and other regional regulations. |
| Barrier Properties |
- Oxygen Transmission Rate (OTR): ≤ 5 cm³/(m²·24h·atm) (customizable for ultra-low OTR)
- Moisture Vapor Transmission Rate (MVTR): ≤ 1 g/(m²·24h) (depending on layer structure)
- Excellent light and odor barrier. |
| Thickness |
Customizable: 60–150 μm (microns) (typical range; exact thickness tailored to barrier and mechanical requirements). |
| Width |
Machine-compatible widths: 200–1200 mm (customizable to fit your packaging equipment specifications). |
| Roll Length |
Customizable: 500–5000 meters per roll (dependent on thickness and winding capacity). |
| Heat Sealability |
High-strength heat seal at 120–200°C (sealing parameters adjustable for different machines); compatible with pillow bags, stand-up pouches, or stick packs. |
| Mechanical Properties |
- Tensile Strength: ≥ 35 MPa (longitudinal) / ≥ 30 MPa (transverse)
- Puncture Resistance: ≥ 50 N (dependent on layer structure)
- Flex Cracking Resistance: Maintains barrier integrity after 1000+ flex cycles. |
| Temperature Resistance |
- Heat Resistance: Up to 120°C (suitable for pre-sterilization if required)
- Cold Resistance: Maintains flexibility at -20°C (ideal for cold storage or transit). |
| Printing |
Supports gravure, flexographic, or digital printing; up to 10 colors with excellent ink adhesion and color fastness; optional matte/gloss laminates, UV varnish, or anti-fog coatings. |
| Surface Treatment |
- Anti-static coating (reduces powder adhesion)
- Slip agents (enhances machine runnability)
- Easy-tear notch (optional for consumer convenience). |
| Customization |
- Layer structure: Tailored barrier levels for oxygen, moisture, or light
- Additives: Anti-microbial, anti-oxidant, or anti-fungal agents (on request)
- Special features: Spout fitment compatibility, re-sealable zippers, or degassing valves (for coffee). |
| Compliance |
FDA 21 CFR Part 177, EU Regulation 10/2011, China GB 9683, and other global food contact safety standards; BPA-free (optional). |
| Applications |
Ideal for milk powder (infant formula, adult nutrition), coffee (ground, whole bean, instant), protein powders, spices, baking mixes, and other dry powdered foods. |
