Description

Technical Field

[0001] The utility model relates to the technical field of aluminum foil paper, in particular to a thermal sealing aluminum foil paper for paper products based on hot melt adhesive. Background Technique

[0002] Aluminum foil paper refers to the paper formed by laminating and bonding aluminum foil liner paper and aluminum foil. It is soft and easy to deform, just like paper, and does not rebound after deformation. It can be shaped, ensuring light shielding, no dropping, light impermeability, no pollution, and low price. It is used for moisture-proof and decorative packaging of high-grade cigarettes, candies and other foods.

[0003] After the existing aluminum foil paper wraps an object, although it can be bent and wrinkled by itself and wrapped on the object, after a long time, it is still easy to loosen from the object, resulting in low wrapping firmness. Therefore, it is necessary to develop a thermal sealing aluminum foil paper for paper products based on hot melt adhesive. Content of the Utility Model
