Problems solved by technology

[0004] The technical problem to be solved in the present invention is that the existing PVDC casing film has a large ink content, a large amount of solvent residue, and a high production cost. It provides a PVDC casing interlayer printing packaging film and a production method thereof that print pictures in the printing mode. This kind of packaging film has small ink content, very little solvent residue, and low production cost.

Embodiment Construction

[0019] As shown in the figure, this PVDC casing interlayer printed packaging film includes an outer layer 1 and an inner layer 3 that are combined together. The outer layer 1 is a transparent PVDC film, and the inner layer 3 is a white PVDC film. The printing ink layer 2 of printing printing. The back printing ink layer 2 is a polyurethane back printing ink resistant to 121° C. high-temperature cooking solvent. The thickness of the outer transparent PVDC film and the thickness of the inner white PVDC film are both 10-30 μm, and the thickness of the ink layer is 2-4 μm. Of course, the thickness of each layer can be adjusted according to actual conditions.

[0020] The method for preparing the PVDC casing interlayer printed packaging film of the present invention is as follows: the transparent PVDC film is printed with the inner printing printing ink, and then the printing surface of the printed transparent PVDC film is compounded with the white PVDC film by using a compound ma...

Abstract

The invention relates to a PVDC casing interlayer printed packaging film and a production method thereof. The packaging film includes an outer layer and an inner layer combined together, the outer layer is a transparent PVDC film, the inner layer is a white PVDC film, and the inner surface of the outer layer is attached with A back printing ink layer printed by back printing. The production method is to print the transparent PVDC film with the inner printing method of 121°C high-temperature cooking ink, and then use a compound machine to compound the printed surface of the printed transparent PVDC film with the white PVDC film, and the printing ink is sandwiched between two layers of PVDC film. In the middle, no adhesive is applied between the two layers of PVDC film, and the pressure and temperature of the compounding roller and the shrinkage force of the PVDC film are directly compounded. The PVDC casing interlayer printed packaging film with printed pictures in the back printing method of the present invention has good picture layering, brightness and vividness.

Description

technical field [0001] The invention relates to a PVDC packaging film, in particular to a PVDC packaging film for packaging ham sausage food, and also relates to a method for preparing the packaging film. Background technique [0002] PVDC film is the best material for packaging food with its excellent oxygen barrier, moisture barrier and high temperature cooking resistance. Conventional PVDC film is double-layered with a total thickness of 40±2μm, and the casing color is usually red, yellow, orange, etc. Conventional surface printing technology is used, and the surface printing picture lacks layering, vividness and brightness. The quality of its printing picture prevents the quality of PVDC film packaging from being fully utilized. In order to produce a strong picture layering, bright and eye-catching PVDC packaging film must meet the following conditions: (1) The color of the ink is saturated, the printing ink layer is smooth, and the transition of shallow dots is unifor...
