Bullet or blast-proof sheets are an added layer of security that have regularly featured in PTI chairman Imran Khan’s court appearances.

It is hard to gauge the exact grading of the sheets but there are some popular types used across the globe by security agencies for high-profile personalities.

The most popular form of bullet-resistant plastic sheeting is polycarbonate sheet. These sheets are graded to stand bullets and high-resistance impact. Even if they are completely exposed, they won’t shatter.

They are specially designed to protect against forced entry, whether ballistic or from the impact of heavy tools.

Some of their key features are:

• Supreme strength
• Highly durable
• Impact resistant
• They contain Grade Polycarbonate
• Violent-blow resistant
• Ballistic resistant
• Lightweight
• Shatterproof
• UV protection

The Sindh Police has also decided to procure these sheets. The police will keep 10 blast sheets in its district or zonal offices.
