At its most base level, product packaging serves to protect the product inside. Packaging must keep the product safe during shipment between the manufacturing facility and the retailer and must prevent damage while the product sits on the shelf. Therefore, product packaging must be sturdy and reliable. Many companies package their products with seals and locks that prevent tampering and further ensure the safety and integrity of the product. Consumers expect their products to function exactly as intended—secure, dependable product packaging is the best way to ensure just that.
