Detailed Implementation

[0019] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0020] like Figures 1-2 As shown, a packaging film with tear-resistant properties includes a packaging film body 1, a thickened protective portion 2, and adhesive strips 4. The packaging film body 1 includes a middle layer 101, a top layer 102, and a bottom layer 103. The top layer 102 and the bottom layer 103 are respectively provided on the upper and lower sides of the middle layer 101. The top layer 102 and the bottom layer 103 have the same thickness and are specifically polyethylene film layers. The thickened protective portion 2 is fixed on both outer sides of the packaging film body 1, and a protruding edge 3 is fixed on the outer side of the thickened protective portion 2. The protruding edge 3 has an arc-shaped protrusion structure. Adhesive strips 4 are evenly distributed on the upper side of the top layer 102, and the outer surface of the adhesive strips 4 is coated with adhesive strips. It has release paper 5; the upper layer 102 and the lower layer 103 are polyethylene film layers with good toughness, moisture resistance and heat sealing performance. The thickened protective part 2 can protect the edge of the packaging film body 1 and prevent the packaging film body 1 from tearing from the side. It can also prevent the side from being deformed by force to a certain extent. The arc-shaped raised edge 3 makes it easy to peel off the packaging film body 1. It avoids the situation where the multiple packaging film bodies 1 are tightly wrapped, making it inconvenient to peel off the film when using. After peeling off the release paper 5, the adhesive strip 4 can be used. Several adhesive strips 4 at equal intervals facilitate the pasting between the packaging film body 1 and the packaged product or between multiple packaging film bodies 1, which is convenient to use.

[0021] like Figures 2-3As shown, the intermediate layer 101 includes a plant fiber membrane layer 1011, a reinforcing fiber layer 1012, and a tear-resistant buffer layer 1013. The reinforcing fiber layer 1012 is disposed on the outer side of the plant fiber membrane layer 1011, and the tear-resistant buffer layer 1013 is disposed on the outer side of the reinforcing fiber layer 1012. The tear-resistant buffer layer 1013 is made of PVC-UH material. The intermediate layer 101 also includes an abrasion-resistant layer 1014 and an antioxidant layer 1015. The abrasion-resistant layer 1014 is disposed on the outer side of the tear-resistant buffer layer 1013, and the antioxidant layer 1015 is disposed on the outer side of the abrasion-resistant layer 1014. The abrasion-resistant layer 1014 is specifically a BOPP film, and the antioxidant layer 1015 is specifically an antioxidant PVC film. The intermediate layer 101 also includes... The outer surface of the anti-oxidation layer 1015 is provided with an antibacterial coating 1016; the intermediate layer 101 is mainly composed of a plant fiber film layer 1011, which has good biocompatibility and biodegradability; the reinforcing fiber layer 1012 is a fiber composite plastic film, which helps to enhance the structural strength of the plant fiber film layer 1011; the tear-resistant buffer layer 1013 is made of PVC-UH material, which has high strength, impact resistance, and tensile strength, and can effectively improve the tear resistance of the main body of the packaging film 1; the wear-resistant layer 1014 is a BOPP film, which is lightweight and has good stability; the anti-oxidation layer 1015 is an anti-oxidation PVC film, which has stable performance, is waterproof, moisture-proof and corrosion-resistant; and the antibacterial coating 1016 gives the intermediate layer 101 a good antibacterial effect.

[0022] In summary, as Figures 1-3As shown, this tear-resistant packaging film, when used, first wraps the main body 1 of the packaging film around the product being packaged. Then, peeling off the release paper 5 allows the use of adhesive strips 4. Several evenly spaced adhesive strips 4 facilitate the bonding between the main body 1 of the packaging film and the product being packaged, or between multiple layers of the main body 1, thus simplifying packaging. Furthermore, the thickened protective portion 2 protects the edges of the main body 1, preventing tearing from the side. When opening the packaging, the arc-shaped raised edge 3 facilitates the removal of the main body 1, avoiding the inconvenience of removing the film when multiple layers are tightly wrapped. During use, the intermediate layer 101, primarily composed of a plant fiber film layer 1011, exhibits excellent durability. The product has good compatibility and biodegradability. The fiber layer 1012 is a fiber composite plastic film, which helps to enhance the structural strength of the plant fiber film layer 1011. The tear-resistant buffer layer 1013 is made of PVC-UH material, which has high strength, impact resistance, and tensile strength, and can effectively improve the tear resistance of the main body of the packaging film 1. The wear-resistant layer 1014 is BOPP film, which is lightweight and has good stability. The anti-oxidation layer 1015 is an anti-oxidation PVC film, which has stable performance, is waterproof, moisture-proof and corrosion-resistant. The antibacterial coating 1016 gives the middle layer 101 a good antibacterial effect. The outer upper layer 102 and lower layer 103 are polyethylene film layers with good toughness, moisture resistance and heat-sealing performance. This completes the use process of the packaging film with tear resistance.
