Product Overview: Opaque Stretch Wrap 
 

Opaque stretch wrap is a specialized packaging film designed to block light completely, ensuring contents are shielded from UV and visible light exposure. Key applications include:  

- Food & Beverage: Packaging light-sensitive products like dairy, beer, and oils to prevent oxidation and flavor degradation.  

- Pharmaceuticals: Protecting medications, vitamins, and biologics from light-induced chemical reactions.  

- Electronics: Securing light-sensitive components (e.g., semiconductors, optical devices) during storage and transit.  

- Luxury Goods: Concealing high-value items for secure and discreet shipping.  

Core Advantages:  

- 100% Light Blocking: Complete opacity to prevent UV and visible light penetration.  

- High Load Retention: Superior stretchability and puncture resistance for heavy-duty applications.  

- Temperature Resilience: Performs flawlessly in extreme temperatures (-40°C to 80°C).  

- Sustainability: Recyclable LLDPE materials with eco-friendly additives.
