[0002] Packaging film is a material used to package and protect goods, usually made of plastic, paper, metal or other composite materials. Its main function is to protect goods from physical damage, pollution and moisture, and it can also be used to extend the shelf life of goods. In addition, packaging film can also be used to identify and display goods, as well as facilitate transportation and distribution. In modern society, packaging film is widely used in various industries, including food, medicine, cosmetics, electronics, household goods, etc. With the advancement of science and technology and the improvement of environmental awareness, the materials and production processes of packaging films are also constantly improving to meet higher environmental protection and functional requirements.

[0003] The "PTP packaging film" disclosed in application number CN202321145376.2 solves the existing PTP packaging film. After printing a pattern on a 20μm thick aluminum foil, a surface film is composited on the aluminum foil with the pattern to form a PTP packaging film with a pattern. However, printing the pattern directly on the aluminum foil is costly and slow. However, the PTP packaging film in this application has poor toughness when used. In practice, packaging films with poor toughness are often easily broken or damaged when wrapping goods, which not only increases the risk of damage to goods during transportation or handling, but may also lead to economic losses and reduced customer satisfaction.

The first reinforcing rib layer 101, the gas barrier layer 102, the moisturizing layer 103, the waterproof layer 104, the second reinforcing rib layer 105 and the printing layer 106 are all covered with edge sealing layers 107 on both sides. The first reinforcing rib layer 101 and the second reinforcing rib layer 105 are both transverse structures, which provide high toughness and make the packaging film easy to tear transversely; enhance the puncture resistance; protect the internal products, the first reinforcing rib layer 101 and the second reinforcing rib layer 105 are both made of polyethylene, the gas barrier layer 102 is made of polyvinylidene chloride, the moisturizing layer 103 is made of polyurethane, the waterproof layer 104 is made of polypropylene, the printing layer 106 is made of flexographic printing ink, and the edge sealing layer 107 is made of polyvinyl alcohol.

[0028] When working, first, put the goods into the packaging film structure 1 to ensure that the goods are evenly wrapped in the film. The gas barrier layer 102 covered by the first reinforcing rib layer 101 is tightly attached to the goods to prevent harmful gases such as oxygen and moisture from entering, extend the shelf life of the goods, and maintain the freshness of the food. According to the needs of the goods, the humidity inside the package is adjusted to keep the goods moist and prevent quality loss caused by drying. When wrapping the goods, the packaging film structure 1 can prevent moisture penetration, protect the goods from moisture, and increase the durability of the packaging film. The second reinforcing rib layer 105 provides high toughness, making the packaging film easy to tear horizontally, enhancing the puncture resistance, and protecting the internal goods. The printed layer 106 can print product information, company logo, etc. on the surface of the printed layer 106 to improve the recognition of the goods, protect the internal layer, and prevent wear. Finally, the edge sealing layer 107 can protect the internal layer and prevent wear.

[0029] In this way, the product is completely wrapped in the high-toughness packaging film, which can prevent the invasion of external harmful substances, maintain the freshness and moisture of the product, protect the product from moisture, and improve the recognition of the product and extend the shelf life of the product. The use process of this high-toughness packaging film is simple and convenient, which greatly improves the packaging efficiency and the shelf life of the product.

[0030] Embodiment 2:

[0031] On the basis of Example 1, the packaging film structure 1 is arranged on the side surface of the reel 2, and a cutting structure 3 is arranged at one end of the reel 2. The cutting structure 3 includes a connecting rod 301 and a cutting knife 303. The connecting rod 301 is fixedly connected to one end of the reel 2, and the cutting knife 303 is fixedly installed on the lower surface of the connecting rod 301. When the packaging film is used, when the packaging film is long enough, the packaging film structure 1 is lifted upward so that the packaging film structure 1 contacts the cutting knife 303. After the edge sealing layer 107 at one end of the packaging film is cut by the cutting knife 303, the packaging film structure 1 can be directly torn open horizontally for use. A protective cover 302 is hinged at one end of the connecting rod 301. The protective cover 302 protects the cutting knife 303 to prevent people from being accidentally injured by the cutting knife 303.

[0032] After the high-toughness packaging film structure 1 is used to package the goods, the packaging film structure 1 needs to be cut for easy stacking and transportation. During operation, the packaging film structure 1 is first gently lifted up to contact the pre-set cutting knife 303, and the vertical edge sealing layer 107 inside the packaging film structure 1 is cut. After cutting, other layers of the packaging film structure 1, such as the reinforcing rib layer, the gas barrier layer 102, the moisturizing layer 103, the waterproof layer 104, etc., can be easily torn horizontally because the edge sealing layer 107 is lost, which reduces the complexity of manual operation and the labor intensity during the packaging process. When the cutting knife 303 is not in use, in order to ensure the safety of the staff and prevent the cutting knife 303 from accidentally starting and causing injuries, a protective cover 302 needs to be covered on the outside of the cutting knife 303 at the lower end of the connecting rod 301, which can effectively block the cutting knife 303 and prevent it from being touched, ensuring the safety of the staff and avoiding potential industrial accidents.

[0033] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the application should be included in the protection scope of the present application.
