Bubble wrap is a lightweight, shock-absorbing, and insulating material made from low-density polyethylene (LDPE), commonly used for protecting fragile items. Key specifications include bubble diameters of 9.5–10 mm (small) or 32 mm (large), with material weights typically ranging from 40 to 80 GSM and roll widths between 300 mm and 2200 mm. 

Common Bubble Wrap Specifications:

• Material: LDPE (Low-Density Polyethylene).
• Bubble Size (Diameter): Small (approx. 10 mm) or Large (approx. 32 mm).
• Bubble Height: Small (approx. 4 mm) or Large (approx. 13 mm).
• Weight (Density): Generally 40–80 GSM (Grams per Square Meter), with heavier options available for increased durability.
• Roll Widths: Standard sizes range from 300 mm to 2200 mm.
• Roll Lengths: Commonly 25 m, 50 m, or 100 m.
• Structure: Available in 2-layer (barrier layer + bubble layer) or 3-layer (barrier + bubble + flat surface).
• Properties: Transparent, waterproof, heat-sealable, and recyclable.
