Packing PP White Plastic Bottle With Screw Cap

Screw caps are small covers designed to fit over the heads of screws. They serve multiple purposes. Firstly, they provide a decorative finish, hiding the screw head and giving a more polished look. Secondly, they can protect the screw from corrosion and damage. Screw caps are available in various colors and materials to match different surfaces and applications. They are easy to install and can enhance the overall appearance of a product or structure.
