Abstract

The invention relates to the technical field of plastic packaging films, and provides a reusable gift packaging composite plastic film and a method for preparing the same. The reusable gift packagingcomposite plastic film which is a three-layer composite gift packaging film can be prepared by the aid of three-layer co-extrusion tape casting film forming processes. A polytrimethylene terephthalatefilm is used as an inner layer of the three-layer composite gift packaging film, a polypropylene film is used as an intermediate layer of the three-layer composite gift packaging film, and another polytrimethylene terephthalate film is used as an outer layer of the three-layer composite gift packaging film. Compared with the traditional methods, the reusable gift packaging composite plastic filmand the method have the advantages that the reusable gift packaging composite plastic film prepared by the aid of the method is high in tensile strength, breaking elongation and transparency; the shape of the reusable gift packaging composite plastic film can be restored at the low heating temperatures or under the effect of low tensile force, fold generated after the reusable gift packaging composite plastic film is reused can be eliminated, and accordingly the reusable gift packaging composite plastic film can be reused.

Description

technical field [0001] The invention belongs to the technical field of plastic packaging films and provides a reusable composite plastic film for gift packaging and a preparation method. Background technique [0002] Plastic packaging and plastic packaging products have the advantages of a wide variety, light weight and beauty, and are not easy to break. The development speed far exceeds that of traditional paper, metal, glass and other packaging materials, and their market share is increasing. Composite plastic flexible packaging has been widely used in daily life, food, medicine, chemical industry and other fields, and has been developed rapidly and widely used. [0003] In packaging materials, as an important carrier of gifts, gift packaging materials are also part of gifts. At present, as a simple packaging composite plastic film, it can not only make the packaging contents moisturizing, fragrant, beautiful, fresh, light-proof, and anti-aging. Penetration, good durabili...
