Introduction to Aluminum-Plastic Cap Products
I. Product Overview
An aluminum-plastic cap is a sealing lid made from a composite of aluminum and plastic, combining the strength of metal with the flexibility of plastic. It is widely used in packaging and sealing applications across industries such as pharmaceuticals, food, cosmetics, and chemicals. The product boasts excellent sealing performance, corrosion resistance, and easy-open features, effectively protecting contents from external factors like moisture, oxygen, and microorganisms. This ensures extended shelf life while maintaining product safety for consumers.
II. Product Features
1. Diverse Material Options
Aluminum materials: High-purity aluminum foil with antioxidant and puncture-resistant properties, available in various thicknesses upon request (e.g., 0.2mm–0.5mm).
Plastic layers: Food-grade PE/PP, medical-grade plastic, or industrial-grade composite materials, meeting safety standards for various industries.
Outstanding Sealing Performance
Employing a heat-sealing process to ensure a tight fit with the bottle opening, the product undergoes dual testing for both air-tightness and water-tightness. It is suitable for special sealing requirements such as vacuum packaging and nitrogen-flushing packaging.
Flexible adaptability
Supports multiple bottle types (round, square, and uniquely shaped bottles) and sizes (diameter ranging from 10mm to 50mm), with customizable opening methods (tear-off, pry-open, or screw-cap designs). The surface can be printed with brand logos, product information, or anti-counterfeiting markings, helping to enhance your brand image.
Environmental Protection and Durability
Aluminum materials are recyclable, and the plastic layer complies with RoHS environmental standards. They offer excellent resistance to high temperatures (-20°C to 120°C), as well as strong acid- and alkali-resistant properties, making them suitable for long-distance transportation and challenging storage conditions.
