1. Classification of Plastic Caps by Material

Plastic caps are categorized based on their polymer composition, each offering unique properties for specific applications:

HDPE (High-Density Polyethylene) Caps
Known for high chemical resistance and rigidity, HDPE is ideal for detergent bottles, pharmaceutical containers, and industrial packaging. Its low permeability makes it suitable for liquids requiring airtight seals.

PP (Polypropylene) Caps
Lightweight and heat-resistant, PP caps are widely used in food packaging (e.g., yogurt containers) and automotive fluids. Their excellent fatigue resistance supports repetitive opening and closing.

LDPE (Low-Density Polyethylene) Caps
With superior flexibility, LDPE is preferred for squeeze bottles and cosmetic tubes. However, its higher gas permeability limits use in carbonated beverages.

PC (Polycarbonate) Caps
PC’s transparency and high impact strength make it ideal for premium water bottles, medical devices, and UV-resistant outdoor products.

PET (Polyethylene Terephthalate) Caps
Commonly paired with PET bottles, these caps are lightweight and recyclable, dominating the beverage industry.

2. Applications Across Industries

Plastic caps cater to diverse sectors:

Food & Beverage: PP and PET caps ensure freshness and tamper evidence for bottled drinks, sauces, and snacks.

Pharmaceuticals: HDPE and PC caps provide child-resistant and moisture-proof solutions for pill bottles and syringes.

Cosmetics: LDPE and acrylic-based caps offer aesthetic appeal and precise dispensing for creams and serums.

Industrial Chemicals: HDPE and PBT caps resist corrosive substances in cleaning agents and automotive fluids.

3. Advanced Cap Mould Technologies

As a multi-cavity plastic cap mould innovator, Yige Mold integrates state-of-the-art technologies to optimize production efficiency and precision:

Multi-Cavity Mould Design
High-cavitation moulds (e.g., 64+ cavities) enable mass production while maintaining dimensional consistency. This reduces cycle times and costs for large-scale orders.

Hot Runner Systems
Eliminating material waste, hot runner technology ensures uniform melt distribution, critical for complex geometries like tamper-evident bands and threaded closures.

Precision Engineering
CNC machining and CAD/CAM software guarantee micron-level accuracy, essential for caps requiring airtight seals or regulatory compliance (e.g., FDA, EU standards).
