Abstract

The invention provides a multilayer composite film, which comprises an outer layer, an ink treatment layer, first adhesive, a middle layer, a bottom layer, second adhesive and a high-isolation treatment layer, wherein the outer layer is used as a printing base material and can be used for printing a pattern on an inner surface of the surface through ink treatment, the first adhesive bonds the inner surface of the outer layer with the middle layer, the middle layer is arranged below the inner surface of the outer layer, the bottom layer is arranged below the inner surface of the middle layer, the second adhesive bonds the inner surface of the middle layer with the bottom layer, or a second middle layer and third adhesive are arranged below the middle layer, and the high-isolation treatment layer is coated at a preset position of the internal part of the multilayer composite film to realize isolation structure treatment. Therefore, through the high-isolation treatment layer, the ink and the adhesive are isolated and prevented from being volatilized and dispersed, and the environmental-friendly, nontoxic and pollution-free multilayer composite film is obtained.

Description

Technical field

[0001] The present invention is a multi-layer composite film (Flexible Packing Material), which is related to the printing and interlayer composite (bonding) method of the multi-layer composite film, especially the non-polluting printing method, which is made of non-toxic water-based oil (color) ink. Printing, water-based adhesives for adhesion, no harm to the human body at all, or a forced isolation structure to isolate harmful substances, is a multi-layer composite film that is environmentally friendly, non-toxic, and non-polluting.

Background technique

[0002] With the rapid development of multi-layer composite packaging items, which are convenient for people to use, the amount of multi-layer composite packaging is increasing, and various series (food, electronics, industry, biotechnology and medical care, etc.) belong to multi-layer composite packaging. Multi-layer composite plastic film is used for packaging. Regarding products packaged with multi-l...

Embodiment Construction

[0102] First of all, a kind of multi-layer composite membrane of the present invention, the first embodiment, such as figure 2 As shown, the substrate uses a plastic film such as a layer of PET (polyester film) or ONY (nylon film) on the outer layer, or paper made of pulp that can be used as an outer layer, etc., on the inner surface of the outer layer Or surface printing patterns, printing is printed on the outer layer with water-based ink-WB-Ink (Water Base Ink), and then water-based adhesive-WB-DL (Water Base Dry Lamination) or water-based solvent two-component thermal Extrusion film-WB-EL (Water Base Extrusion Lamination) is attached to an AL aluminum material, and then a water-based adhesive-WB-DL (Water Base Dry Lamination) is used to adhere to ONY (Orient Nylon through alignment stretched nylon film), and another water-based adhesive Adhesive-WB-DL (Water Base Dry Lamination) or water-based solvent two-component hot extrusion film-WB-EL (Water Base Extrusion Lamination...
