Description

Degradable cold transfer membrane

Technical Field

The utility model relates to a transfer membrane, specifically, mainly relate to a cold transfer membrane of degradable.

Background

The cold transfer film is widely applied to packing paper which is mainly used for occasions such as high-grade packing boxes, high-grade cigarette packing boxes, laminating films, medicine and cosmetic packages and the like. The base material film of the cold transfer film used at present is mainly a BOPP film, but the BOPP film contains non-degradable plastic components, so that environmental pollution is easily caused.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art, the utility model provides a cold transfer membrane of degradable.

The utility model discloses a cold transfer membrane of degradable, include by lower supreme degradable substrate thin layer and the radium-shine layer that stacks gradually the setting.

Preferably, one surface of the degradable substrate film layer is a corona surface, and the other surface of the degradable substrate film layer is a heat-sealing surface; the laser layer is arranged on the corona surface.

Preferably, the degradable substrate film layer is made of a BOPLA degradable film, an acetate fiber degradable film or wood pulp paper.

The beneficial effect of this application lies in: the degradable base material film is used for replacing a BOPP film as the base material film, so that the excellent performance of the cold transfer film is reserved, the cold transfer film is degradable, and the environment is protected.

Detailed Description

In the following description, numerous implementation details are set forth in order to provide a more thorough understanding of the present invention. It should be understood, however, that these implementation details should not be used to limit the invention. That is, in some embodiments of the invention, details of these implementations are not necessary. In addition, some conventional structures and components are shown in simplified schematic form in the drawings.

It should be noted that all the directional indicators in the embodiments of the present invention, such as upper, lower, left, right, front and rear … …, are only used to explain the relative position relationship between the components, the motion situation, etc. in a specific posture as shown in the drawings, and if the specific posture is changed, the directional indicator is changed accordingly.

In addition, the descriptions related to "first", "second", etc. in the present invention are only for description purposes, not specifically referring to the order or sequence, and are not intended to limit the present invention, but only to distinguish the components or operations described in the same technical terms, and are not to be construed as indicating or implying any relative importance or implicit indication of the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions in the embodiments may be combined with each other, but it must be based on the realization of those skilled in the art, and when the technical solutions are contradictory or cannot be realized, the combination of the technical solutions should not be considered to exist, and is not within the protection scope of the present invention.

For further understanding of the contents, features and functions of the present invention, the following embodiments will be exemplified in conjunction with the accompanying drawings as follows:

referring to fig. 1, fig. 1 is a schematic cross-sectional structure diagram of a degradable cold transfer membrane in this embodiment. The degradable cold transfer film in the embodiment comprises a degradable base material film layer 1 and a laser layer 2 which are sequentially stacked from bottom to top.

Furthermore, one surface of the degradable film layer 1 is a corona surface 11, and the other surface thereof is a heat-sealing surface 12. Laser layer 2 is disposed on corona surface 11. Have viscidity between corona face 11 and the laser layer 2, so set up laser layer 2 on corona face 11, laser pattern shaping is effectual.

In practical application, the degradable substrate film layer 1 is made of a BOPLA degradable film, an acetate fiber degradable film or wood pulp paper.

When the degradable cold transfer film is used specifically, the laser layer 2 on the surface of the degradable cold transfer film has a holographic laser effect, and after laser patterns of the laser layer 2 are transferred to paper, the degradable base material thin film layer 1 is rewound and recycled. The recycled degradable substrate film layer 1 can be repeatedly used and can be directly degraded.

At the time of transfer, laser layer 2 is transferred from heat-seal face 12 to a prescribed position. Because the corona surface 11 and the laser layer 2 have viscosity, if the corona surface 11 is transferred, the pattern is easy to deform, and the transfer is not complete. And the heat sealing surface 12 of the degradable film layer 1 is pasted on the paper, the laser pattern of the laser layer 2 is transferred from the heat sealing surface 12, the transferred pattern cannot deform, and the transfer effect is good.

To sum up: the degradable base material film is used for replacing a BOPP film as the base material film, so that the excellent performance of the cold transfer film is reserved, the cold transfer film is degradable, and the environment is protected.

The above is only an embodiment of the present invention, and is not intended to limit the present invention. Various modifications and changes may occur to those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the scope of the claims of the present invention.
