A plastic courier bag is a flexible, lightweight packaging solution made from durable polyethylene, widely used for shipping items in e-commerce, courier, and logistics sectors. These bags are typically tamper-proof, featuring a strong adhesive seal that cannot be opened without tearing, ensuring shipment security. With thicknesses usually around 51–60 microns, they are tear-resistant, stretchable, and waterproof, protecting contents from damage during transit. Available in various sizes, plastic courier bags often include a POD (Proof of Delivery) jacket for documentation. Their lightweight nature reduces shipping costs and speeds up the packing process, making them a cost-effective choice for safe deliveries
