Embodiment 1

[0026] An ecological BOPP / PP color printing food packaging film, comprising an upper layer 1, a middle layer 2 and a lower layer 3, the middle layer 2 is covered on the lower layer 3, the upper layer 1 is covered on the middle layer 2, The upper layer 1 is a PP coating layer, the middle layer 2 is a color printing film layer, and the lower layer 3 is a BOPP layer.

[0027] In the eco-type BOPP / PP color printing food packaging film, the percentage of each layer in the total mass is: PP coating layer: 15-32%, color printing film layer: 1-3%, BOPP layer: 65-82%

[0028] In the PP coating layer, the raw materials are PP material and barrier material montmorillonite sodium salt, the auxiliary material is deoxidizer, and the deoxidizer is nano-reduced iron powder, and the mass percentage of each component is: PP material: 88-95% %, barrier material montmorillonite sodium salt: 2-7%, nano-reduced iron powder: 3-7%.

[0029] In this example, PP coating layer: 15%, color printing film...

Embodiment 2

[0039] In this example, PP coating layer: 18%, color printing film layer: 2%, BOPP layer: 80%

[0040] In the PP coating layer, the raw materials are PP material and barrier material montmorillonite sodium salt, the auxiliary material is a deoxidizer, and the deoxidizer is nano-reduced iron powder, and the mass percentage of each component is: PP material: 89%, Barrier material montmorillonite sodium salt: 6.5%, nano-reduced iron powder: 4.5%.

[0041] Other schemes of this embodiment are all the same as in Embodiment 1.

Embodiment 3

[0043] In this example, PP coating layer: 24%, color printing film layer: 1.5%, BOPP layer: 74.5%

[0044] In the PP coating layer, the raw materials are PP material and barrier material montmorillonite sodium salt, the auxiliary material is deoxidizer, and the deoxidizer is nano-reduced iron powder, and the mass percentage of each component is: PP material: 90%, Barrier material montmorillonite sodium salt: 6%, nano-reduced iron powder: 4%.

[0045] Other schemes of this embodiment are all the same as in Embodiment 1.

Abstract

The invention provides an ecological type BOPP / PP color printing food packaging film, which comprises an upper layer, a middle layer and a lower layer, wherein the middle layer is covered on the lower layer; the upper layer is covered on the middle layer; the upper layer is a PP laminated film layer; the middle layer is a color printing film layer; and the lower layer is a BOPP layer. The invention also provides a method for manufacturing the ecological type BOPP / PP color printing food packaging film. The invention provides the ecological type BOPP / PP color printing food packaging film capable of enhancing the environmental protection property and effectively eliminating hidden troubles to the food safety, and the method for manufacturing the ecological type BOPP / PP color printing food packaging film.

Description

technical field [0001] The invention relates to an ecological type BOPP / PP color printing food packaging film and a manufacturing method thereof. Background technique [0002] People pay more and more attention to health, and food hygiene is a major issue for everyone. Food packaging is one of the key measures to ensure food hygiene and extend food shelf life. [0003] At present, domestic food packaging bags use BOPP / PP color packaging film, and food is packaged by automatic packaging machines, accounting for about 70% of all food packaging. It can be seen that the demand for packaging film is huge. However, the processing technology of BOPP / PP color packaging film has always been using BOPP film (biaxially oriented polypropylene film) and PP film (two-layer co-extruded polypropylene blown film), using the traditional dry composite process, only Apply an adhesive to the film to be compounded, and then bond it. The name of the operating machine for dry compound bonding is a...
