20g PET Neck Ring
Product Features
DLC Ultra-Hard Coating Technology
The Neck Ring surface adopts a multi-layer composite DLC coating process, forming an amorphous carbon-based high-hardness protective layer. The coefficient of friction is reduced to less than 30% of that of traditional chrome plating, significantly lowering melt flow resistance and material adhesion, and extending the service life of the Neck Ring.
The coating offers excellent corrosion resistance and chemical inertness, making it suitable for high-temperature injection molding environments. It prevents preform yellowing or transparency reduction caused by PET degradation, ensuring the visual quality of finished products.
Precision Machining and Tolerance Control
Utilizing five-axis CNC machining technology, the flow channels and molding surfaces of the Neck Ring achieve tight tolerance control, ensuring uniform preform wall thickness and eliminating molding defects caused by localized stress concentration in ultra-thin wall preforms.
Environmental and Sustainability Compatibility
The Neck Ring coating is non-toxic and harmless, compliant with FDA and EU food contact material standards, and suitable for high-hygiene packaging applications such as pharmaceuticals and infant food.
Application Scenarios
Small-Capacity Food Packaging:
Compatible with ultra-thin wall designs, the lightweight bottle body and strong sealing performance meet the requirements of portable packaging.
Pharmaceutical and Cosmetic Packaging:
The high-gloss Neck Ring forms smooth bottle necks, ensuring cap airtightness and resistance to repeated opening and closing.
Eco-Friendly Lightweight Packaging:
Suitable for the production of disposable cup and food container preforms, supporting high-percentage recycled material usage and aligning with global plastic reduction policies.
High Value-Added Bottle Customization:
For special-shaped necks or embossed preforms, the Neck Ring’s precision machining enables detailed surface replication, enhancing product differentiation and competitiveness.
