Problems solved by technology

The production of aluminum smelting and aluminum foil is energy-intensive. In addition, the aluminum-coated or aluminum-foil composite paper produced is relatively difficult to degrade and is not environmentally friendly.
As the country pays more and more attention to environmental protection and resource conservation, vacuum aluminum-coated paper is widely used, but its production process is complicated, the cost is relatively high, and it is quite difficult to promote

Embodiment 1

[0017] A production process of an aluminum-free environment-friendly lining paper imitating the metal texture of aluminum foil is carried out according to the following steps:

[0018] ⑴Compound the aluminum foil backing paper with the OPP film through the adhesive. The equipment used is a compound machine. The machine speed is controlled at 90m / min, the temperature is controlled at 85°C, and the coating amount is controlled at 2.5g / m 2 , the specification of aluminum foil backing paper is 50g / m 2 , the adhesive consists of the following components by weight percentage: water 68%, polyurethane resin 24%, acrylic resin 8%;

[0019] (2) After the aluminum foil backing paper and the OPP film are laminated, put them in the drying room for 20 hours, the temperature of the drying room is controlled at 40°C, and then the OPP film is peeled off on the peeling machine, and the peeling speed is controlled at 180m / min. The peeled OPP film is collected The rolls are ready for use, and th...

Abstract

The invention relates to a process for producing lining papers for cigarettes and foods, in particular to a process for producing non-aluminum environment-friendly lining papers with similar metal texture of aluminum foil. The process comprises the following steps of: compounding 30-90 / m<2> of papers with an O-phenylphenol (OPP) film via adhesive and drying, wherein the amount of the adhesive is controlled in 2.0-3.0g / m<2>; putting the compound paper film into an oven for 24 hours, peeling off the OPP film, carrying out a gravure on the backing paper without the OPP film via silver paste or color ink, and then printing the backing paper for a second time via pearl ink. In the process for producing non-aluminum environment-friendly lining papers with similar metal texture of aluminum foil,an aluminum-plating process and an aluminum foil compound process are not needed, and the use effect is good; moreover, the process has the advantages of energy conservation, environment protection and national degradation.

Description

technical field [0001] The invention relates to a production process of inner lining paper for cigarettes and food, in particular to a production process of aluminum-free environmental protection inner lining paper imitating the metal texture of aluminum foil. Background technique [0002] In order to achieve a noble and beautiful packaging effect, the existing inner liner paper for cigarettes and food is usually packaged with aluminized or composite paper formed by compounding aluminum foil and paper. The production of aluminum smelting and aluminum foil is energy-intensive, and the aluminum-coated or aluminum-foil composite paper produced is relatively difficult to degrade and is not environmentally friendly. As the country pays more and more attention to environmental protection and resource conservation, vacuum aluminum-coated paper is widely used, but its production process is complicated, the cost is relatively high, and it is quite difficult to promote.
