Composite Paper Corners for Metal Packaging (2551595)
This patent relates to a composite paper corner for metal packaging. It belongs to the field of metal packaging. It is based on pulp as raw material, made of "L" type paper substrate corners. It is characterized by that the inside of the "L" type paper-based escaping protective corner is coated with a rustproof layer and the outer side is coated with a waterproof layer. The advantages are: since the utility model adopts the waterproof layer and the rustproof layer, only the corners of the students are strong and durable, and they are waterproof and rust-proof, thereby minimizing the erosion of the packaging steel materials such as air, moisture and rainwater. In addition, the adsorption between the paper protection angle and the steel is better, so that the force is uniform, and the buffer and the component force are used, and the damage of the protection angle to the steel and the damage to the packaging film are effectively prevented.
