Metalized PE Film (VMPE) is a composite packaging material produced through the vacuum metallization process. The principle involves heating aluminum (or other metals) to vaporization in a high-vacuum environment, then uniformly depositing the metal as nanoscale particles onto the surface of polyethylene (PE) film. This forms a metallic coating only 0.01–0.1 microns thick, endowing the material with both the flexibility of PE and the barrier properties of metal. Core Characteristics 1. High Barrier & Chemical Resistance The metallic coating effectively blocks oxygen, water vapor, oils, and certain chemicals, making it ideal for moisture-proof and corrosion-resistant packaging (e.g., oily foods, chemical products). Superior acid/alkali resistance compared to metallized polypropylene films (e.g., VMCPP), suitable for high-oil/salt or corrosive contents. 2. Flexibility & Heat Sealability Thanks to its PE base, VMPE is soft and highly stretchable, resisting bending/folding damage and suitable for flexible bags (e.g., flat-bottom pouches, skin packaging). Excellent heat-sealing performance allows it to serve directly as a heat-seal layer in laminates without additional coatings, simplifying processing. 3. Lightweight & Cost Efficiency The ultra-thin metallic layer makes VMPE 1/5 the weight of traditional aluminum foil, reducing transportation costs and material waste. Lower production costs than pure aluminum foil composites, with stable PE raw material prices enhancing cost-effectiveness. 4. Printing Compatibility Surface corona treatment improves ink adhesion, enabling high-speed printing and customizable matte/gloss finishes for retail packaging with strong brand identities.
