Problems solved by technology

[0004] However, this kind of composite in-mold label has the disadvantage of difficulty in venting when it is placed in the mold and the molded product is formed. In the case of insufficient exhaust, it is easy to cause the label and the molded product to be not tightly combined, which ultimately affects the product quality.
In addition, since the base film layer of the composite in-mold label is made of BOPP, and the melting point of BOPP is relatively high, it makes the combination of BOPP and molded products relatively difficult, and the combination effect is not ideal.

Embodiment Construction

[0023] The composite in-mold label of the present invention as shown in FIG. 2 is composed of a base film layer 1 , an ink layer 2 and a transparent coating layer 3 . Wherein the ink layer 2 constitutes the pattern or text of the label, which is printed on the inner side of the transparent coating layer 3 . The base film layer 1 and the transparent coating layer 3 are bonded together by a strong composite glue 4 . Of course, the base film layer 1 and the transparent coating layer 3 can also be compounded together by other compounding methods such as extrusion compounding, dry compounding or solvent-free compounding.

[0024] Wherein the transparent coating layer 3 may be a BOPP film, a BOPET film or a BOPA film. These films allow the resulting labels to be stiff, scratch-resistant and abrasion-resistant.

[0025] The ink layer adopts sun-resistant, alkali-resistant and heat-resistant ink.

[0026] The base film layer 1 adopts a layered structure consisting of at least two l...

Abstract

A compound in-mold label is composed of a film substrate with air exhausting veins for exhausting air on moulding, and a transparent covering film with pattern and characters printed on its inner surface.

Description

technical field [0001] The invention belongs to the technical field of plastic products and packaging materials, relates to a label pasted on a container, and in particular designs a composite film inner label. Background technique [0002] Ordinary labels are printed on the surface of PE, PP, synthetic paper or paper. Such labels have poor abrasion resistance and chemical resistance, and are easy to fall off from the container. Later, in-mold labels appeared. In-mold labels can be placed in the mold and combined with the molded product during in-mold molding, so that it is not easy to peel off when pasted on the molded product. [0003] The Chinese utility model patent specification of the authorized announcement number CN 2855738Y discloses a utility model of the applicant named "a composite in-mold label". The composite in-mold label is shown in Figure 1, including a base film layer 1 and the ink layer 2 constituting the pattern also include a transparent coating layer 3...
