Problems solved by technology

[0002] Most of the existing gravure packaging box surface paper is coated white board paper or white cardboard. Disadvantages such as uniformity and poor folding resistance
When printed by a gravure printing machine, due to the uneven weight, the tension is not balanced, and the water absorption rate is high, the printed matter absorbs a lot of ink, the color is not bright, the registration is not accurate, the reject rate is high, the quality is unstable and the waste is large

Embodiment 1

[0017] Embodiment 1, special composite wrapping paper for gravure printing, is formed by bonding the upper layer paper 1 and the lower layer lining paper 3 through the adhesive layer 2, the upper layer paper 1 is 50-100 grams of coated paper, and the lower layer lining paper 3 is 110-350 grams of gray board paper. The adhesive is latex, the dosage is 5-30g / m 2 .

[0018] The production process of the wrapping paper is as follows: the gray board paper is coated with glue and pressed with the printed coated paper of 50-110 grams, and then dried in 3 ovens. The feeding tension of inner paper is 50-100MPa, the feeding tension of face paper is 30-100MPa, and the amount of glue applied to mesh roller is 5-30g / m 2 , the pressure of the glue roller is 4MPa, the temperature of the three ovens is > room temperature -120°C (such as 60°C), > room temperature -130°C (such as 70°C), > room temperature -150°C (such as 60°C), and the receiving tension is 20- 50MPa, paper feeding speed 100-...

Embodiment 2

[0020] Embodiment 2. In this embodiment, wood pulp paper is selected as the inner paper, and red pigment is added to the adhesive. Consumers can judge the authenticity of the product accordingly. Others are the same as embodiment 1.

Abstract

The invention relates to concave printing dedicated composite packing paper. It belongs to packing technique field. It is made up of upper surface paper and under layer inner paper. The upper surface paper is 50-100g copper plate paper. The under layer inner paper is 110-350g grey board or wood pulp paper. Adhesive is emulsion. And its use level is 5-30g / m2. The adhesive can be added into coloring matter. Its production technique is as follows: stitching gummed 110-350g grey board or wood pulp paper and 50-110g copper plate paper; drying to form. The front and back of its production equipment frame is set inner paper discharge roller, surface paper discharge roller, and receiving roller. The travel of the inner and surface paper is set inner paper tensioner and surface paper tensioner. Inner and surface composite pressure roller is set inner paper pasting pressure roller. The composite paper travel is set baking oven. The pasting pressure roller is made up of the upper pressure roller and the under applicator roll. The advantages of the invention are that the packing paper cost is low; the printing effect is good; the production technique is simple; and the equipment is easy to gain.

Description

technical field [0001] The invention belongs to the technical field of packaging, and in particular relates to a special composite packaging paper for gravure printing, its production process and production equipment. Background technique [0002] Most of the existing gravure packaging box surface paper is coated white board paper or white cardboard. Disadvantages such as uniformity and poor folding resistance. When printed by a gravure printing machine, due to uneven weight, uneven tension, high water absorption rate, large ink absorption, dull color, inaccurate registration, high reject rate, unstable quality and large waste. Contents of the invention [0003] The object of the present invention is to provide a composite wrapping paper with low cost and good printing effect, its production process and production equipment. [0004] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: the special composite packagi...
