Stretch film, also known as stretch wrap, is a highly stretchable plastic film commonly used for wrapping and securing items. Here are the details about stretch films:
1. Materials Used:
-
Typically made from Linear Low-Density Polyethylene (LLDPE).
-
Enhanced with additives to improve stretchability, strength, and clarity.
2. Types of Stretch Films:
-
Hand Stretch Film: Applied manually, suitable for low-volume wrapping.
-
Machine Stretch Film: Designed for automated wrapping machines, ideal for high-volume use.
-
Pre-Stretched Film: Pre-stretched during production, easier to apply, and reduces film usage.
-
Coloured/Opaque Stretch Film: Used for color coding, branding, or privacy.
-
UV Resistant Stretch Film: Protects goods from UV exposure during outdoor storage.
-
Vented Stretch Film: Includes small holes for wrapping products needing airflow (e.g., fresh produce).
3. Common Features:
-
High Elasticity: Can stretch 100%-300% of its original size.
-
Tear Resistance: Ensures durability and protection during handling.
-
Cling Properties: Sticks to itself for secure wrapping.
-
Transparency: Allows easy product identification (clear stretch film).
-
Load Stability: Keeps items tightly bound for transportation or storage.
4. Applications:
-
Industrial Use: Securing pallets, boxes, and heavy machinery.
-
Food Industry: Wrapping perishable goods, fruits, and vegetables.
-
Logistics: Prevents tampering or damage during shipping.
-
Storage: Protects items from dirt, dust, and moisture.
5. Sizes and Thickness:
-
Width: 3 to 18 inches (Hand rolls), up to 60 inches (Machine rolls).
-
Thickness: 10 to 50 microns (varies based on application).
-
Length: Hand rolls (100-300 meters), machine rolls (500-3000 meters).
