When a consumer purchases packaged food, the consumer often wants to see the appearance of the internal food clearly through the outer packaging film, and the food packaged by the packaging film is difficult to avoid collision and friction between packages when being transported and picked up or put down by the consumer, so that fingerprint marks or scratches are often generated on the outer surface of the vacuum skin shrinkage film, and the observation of the consumer on the internal packaged food is influenced.
SUMMERY OF THE UTILITY MODEL
The utility model provides a high transparency vacuum skin shrink film, the transparent wearing layer of preventing scraping of surface coating at outer transparent film to prevent that fingerprint seal of a government organization in old china or scratch from influencing the observation of inside food appearance when touching in high transparency vacuum skin shrink film's surface.
In order to solve the technical problem, the utility model provides a high transparency vacuum skin shrink film, include: the transparent heat sealing layer, the transparent barrier layer and the outer transparent film are sequentially stacked from the inner layer to the outer layer; the outer surface of the outer layer transparent film is coated with a transparent scratch-resistant wear-resistant layer.
Further, the transparent scratch-resistant wear-resistant layer is a transparent silicon dioxide coating.
Further, a transparent antifogging layer is coated between the transparent barrier layer and the outer transparent film.
Further, the transparent antifogging layer is a transparent acrylic resin coating.
Further, the transparent heat sealing layer is a transparent polyolefin film.
Further, the transparent barrier layer is a transparent PVDC film.
Further, the outer transparent film is a transparent polyester film.
The utility model has the advantages that the utility model provides a high-transparency vacuum skin shrinkage film which is attached to the surface of food when being heated through the transparent heat sealing layer of the inner layer to package the food; the outer surface of the transparent heat sealing layer is adhered with the transparent blocking layer through an adhesive so as to block external moisture and oxygen from entering the package to influence the preservation of food; an outer transparent film for protecting the transparent heat sealing layer and the transparent barrier layer from being damaged is attached to the outer surface of the transparent barrier layer; and meanwhile, the outer surface of the outer transparent film is coated with a transparent scratch-resistant wear-resistant layer so as to prevent the outer surface of the high-transparency vacuum skin shrinkage film from generating fingerprint marks or scratches when the outer surface of the high-transparency vacuum skin shrinkage film is touched to influence the observation of the appearance of the internal food.
Additional features and advantages of the invention will be set forth in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention.
In order to make the aforementioned and other objects, features and advantages of the present invention comprehensible, preferred embodiments accompanied with figures are described in detail below.

Detailed Description
To make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be described clearly and completely with reference to the accompanying drawings, and obviously, the described embodiments are some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Example 1
As shown in fig. 1, the present embodiment 1 provides a high transparency vacuum skin shrink film, comprising: the transparent heat sealing layer 1, the transparent barrier layer 2 and the outer transparent film 3 are sequentially stacked from the inner layer to the outer layer; the outer surface of the outer layer transparent film 3 is coated with a transparent scratch-resistant wear-resistant layer 4.
Wherein, the optional transparent scratch-resistant wear-resistant layer 4 can be but is not limited to a transparent silicon dioxide coating.
Alternatively, the transparent heat-sealing layer 1 may be, but is not limited to, a transparent polyolefin film, such as a high-transparency PE film.
Alternatively, the transparent barrier layer 2 may be, but is not limited to, a transparent PVDC film.
Alternatively, the outer transparent film 3 may be, but is not limited to, a transparent polyester film.
Specifically, this embodiment 1 provides a high-transparency vacuum skin shrinkage film, which includes a transparent heat sealing layer 1, a transparent barrier layer 2, and an outer transparent film 3, which are sequentially stacked from an inner layer to an outer layer, and the adjacent layers are bonded together by a polyurethane adhesive; heating the transparent heat-sealing layer 1 to shrink the transparent heat-sealing layer 1 so as to be attached to the surface of food to package the food; the transparent barrier layer 2 is suitable for blocking external moisture and oxygen from entering the package to influence the preservation of food; the outer transparent film 3 is suitable for protecting the inner transparent heat sealing layer 1 and the transparent blocking layer 2 from being damaged, and the service life of the high-transparency vacuum skin shrinkage film is prolonged; meanwhile, the outer surface of the outer transparent film 3 is coated with a transparent scratch-resistant wear-resistant layer 4, so that the outer surface of the high-transparency vacuum skin shrinkage film is prevented from appearing fingerprint marks or scratches when being touched to influence the observation of the appearance of the internal food.
