Abstract
The utility model discloses a plastic packaging film with a pattern capable of disappearing after plastic packaging, which comprises two oppositely laminated composite films, wherein each composite film is of a double-layer structure and comprises a hot-melt resin layer and a substrate layer, the hot-melt resin layers of the two composite films are mutually adhered to form the plastic packaging film, and one hot-melt resin layer is printed with the pattern. In the plastic package process, the transparent pattern disappears along with the melting of the hot-melt resin, so that the effect of publicizing the brand of a client and not influencing the use is achieved.
Description
Technical Field
The utility model relates to the technical field of composite films, in particular to a plastic packaging film with a pattern capable of disappearing after plastic packaging.
Background
The plastic packaging film is the most common composite film in daily life, is a heat-sealing composite film with the most wide dosage and application in the world, and is mainly used for storing photos, pictures and important documents. The plastic packaging film is widely used as a bright transparent plastic packaging film, mainly plays a role in protecting important documents, and does not influence normal use and watching.
Extrusion lamination is a method for preparing a composite film by melting and plasticizing hot-melt resin, such as PE, EVA, EAA and the like, by a plastic extruder, extruding and molding through a T-shaped die, laminating on a substrate, laminating with the substrate, and cooling.
The pattern plastic packaging film in the market has the main production process that the PET surface is printed, and then the PET surface and hot-melt resin are extruded and compounded to obtain the pattern plastic packaging film, but printed logo can play a role in propaganda, but the use of the logo is greatly influenced in the use process, and opaque patterns can often block an object to be sealed.
SUMMERY OF THE UTILITY MODEL
Utility model purpose: in order to overcome the defects of the background art, the utility model discloses a plastic packaging film with a pattern capable of disappearing after plastic packaging.
The technical scheme is as follows: the plastic packaging film with the pattern capable of disappearing after plastic packaging disclosed by the utility model comprises two oppositely-laminated composite films, wherein each composite film is of a double-layer structure and comprises a hot-melt resin layer and a base material layer, the hot-melt resin layers of the two composite films are mutually adhered to form the plastic packaging film, and one hot-melt resin layer is printed with the pattern.
Further, the pattern is a transparent pattern.
Furthermore, the hot-melt resin layer is formed by melting hot-melt resin particles through an extruder, directly extruding the hot-melt resin particles on the base material layer and laminating and compounding the hot-melt resin particles.
Further, the substrate layer is the PET layer, and hot melt resin layer is PE layer or EVA layer or EAA layer.
Has the advantages that: compared with the prior art, the utility model has the advantages that: in the plastic package process, the transparent pattern disappears along with the melting of the hot-melt resin, so that the effect of publicizing the brand of a client and not influencing the use is achieved.
Drawings
FIG. 1 is a schematic diagram of the present invention.
Detailed Description
The technical solution of the present invention is further described below with reference to the accompanying drawings and examples.
The plastic packaging film with a pattern capable of disappearing after plastic packaging as shown in fig. 1 comprises two oppositely laminated composite films 1, wherein each composite film 1 is of a double-layer structure and comprises a hot-melt resin layer 101 and a base material layer 102, the hot-melt resin layers 101 of the two composite films 1 are adhered to form the plastic packaging film, and the pattern 2 is printed on one hot-melt resin layer 101.
The pattern 2 is a transparent pattern, can be customized according to the needs of customers, and plays a role in propaganda.
The substrate layer 102 is a PET layer, the hot-melt resin layer 101 is a PE layer or an EVA layer or an EAA layer, and hot-melt resin particles are directly extruded on the PET layer through the melting of an extruder to be laminated and compounded.
