New technology to solve the problem of moisture in corrugated boxes
In recent years, people's demand for outer packaging of goods has become higher and higher. As a packaging container for goods, corrugated boxes have not only ensured the safety of transportation of goods, but also played a role in beautifying goods, increasing added value and promoting sales. When the corrugated box is wet or subjected to grease penetration, the strength will decrease rapidly, which will seriously affect the quality of the package. In recent years, new moisture-proof glazing cartons appearing on the market have solved the problem of moisture, mildew and fragility of carton packaging.
Japan Toyo Steel Co., Ltd. has developed a pure iron foil of 0.02mm to 0.05mm thick, which is rust-proofed by galvanizing, nickel or tin, and is combined with kraft paper and polyethylene film to form a composite cardboard, which is used for making cardboard boxes. Waterproof, moisture-proof, and can shield electromagnetic waves and anti-static. It is especially suitable for packaging of aquatic products, fruits and vegetables, electronic instruments, semiconductor devices and electromechanical products. The aluminum-plated polyvinyl chloride film is combined with kraft paper to make a carton, which is also waterproof and moisture-proof.
