Embodiment 1

[0057] The preparation of the wrapping paper with halo effect of embodiment 1 comprises the following steps:

[0058] (1) Preparation of transfer coating: put 8 parts of modified acrylate polymer, 8 parts of cellulose acetate butyrate, 5 parts of acetone, and 13 parts of methyl ethyl ketone into the reaction kettle in turn, stir evenly at 1000r / min, and heat up to 35 ℃; then add 38 parts of ethyl acetate, 8 parts of n-propyl ester, 6 parts of ethanol, 3 parts of butyl ester and 3 parts of butanol in sequence, keep the temperature at 35 ℃, stir for 20 minutes, then raise the temperature to 45 ℃, stir 1.5h, cooling and discharge to obtain transfer coating;

[0059] (2) Coating: the wet coating amount is 9-10g / m 2 The reticulated roller, with one-sided one-time coating method, coats the transfer coating prepared in step (1) on the PET film, centering the edge when coating, controlling the width of the edge on one side to be less than 0.5mm, and the dry coating amount is 1.55 g / ...

Embodiment 2

[0064] The preparation of the wrapping paper with halo effect of embodiment 2 comprises the following steps:

[0065] (1) Preparation of transfer coating: Put 6 parts of modified acrylate polymer, 10 parts of cellulose acetate butyrate, 3.5 parts of acetone, and 14 parts of methyl ethyl ketone into the reaction kettle in turn, stir evenly at 1200r / min, and heat up to 35 ℃; then add 37 parts of ethyl acetate, 6 parts of n-propyl ester, 7 parts of ethanol, 3 parts of butyl ester and 3 parts of butanol in sequence, keep the temperature at 35 ℃, stir for 20 minutes, then raise the temperature to 40 ℃, stir 2h, cooling and discharging to obtain transfer coating;

[0066] (2) Coating: the wet coating amount is 9-10g / m 2 The reticulated roller, with one-sided one-time coating method, coats the transfer coating prepared in step (1) on the PET film, centering the edge when coating, controlling the width of the edge on one side to be less than 0.5mm, and the dry coating amount is 1.45 ...

Embodiment 3

[0071] The preparation of the wrapping paper with halo effect of embodiment 3 comprises the following steps:

[0072] (1) Preparation of transfer coating: Put 6 parts of modified acrylate polymer, 10 parts of cellulose acetate butyrate, 3.5 parts of acetone, and 14 parts of methyl ethyl ketone into the reaction kettle in turn, stir evenly at 1200r / min, and heat up to 35 ℃; then add 37 parts of ethyl acetate, 6 parts of n-propyl ester, 7 parts of ethanol, 3 parts of butyl ester and 3 parts of butanol in sequence, keep the temperature at 35 ℃, stir for 20 minutes, then raise the temperature to 40 ℃, stir 2h, cooling and discharging to obtain the transfer coating; wherein, the cellulose acetate butyrate is modified by barium oxide before use, and the amount of barium oxide is 0.3wt% of the cellulose acetate butyrate;

[0073] (2) Coating: the wet coating amount is 9-10g / m 2 The reticulated roller, with one-sided one-time coating, coats the transfer coating prepared in step (1) o...

Abstract

The invention discloses a production technology of packing paper with the effect of halo in many colors. The production technology comprises the following steps: (1) preparing a transfer coating by using modified acrylate polymer as base resin; (2) coating a PET film with the transfer coating to prepare a transfer film; (3) vacuum-aluminizing the transfer film by a vacuum-aluminizing machine; (4) coating the aluminized transfer film with aqueous composite glue by a wet coating machine to be compounded with backing paper, coating the backing paper with a back glue material, and drying; (5) separating an aluminized coating of the compounded and cured product with the base PET film so as to prepare aluminized packing paper; and (6) printing the surface of the packing paper obtained after stripping with printing ink. The packing paper with the effect of halo in many colors has advantages of good luster effect, high tensile strength, low cost, strong alkaline hydrolysis resistance, strong adhesive force, low shrinkage and good anti-adhesion and wear-resisting properties.

Description

technical field [0001] The invention relates to a packaging composite material, in particular to a packaging paper with a halo effect applied to cigarette packaging and a production process thereof. Background technique [0002] Metallized packaging paper is mainly divided into: aluminum foil composite paper (first generation), 0.006mm aluminum foil and paper lamination, originated in the early 1990s, its disadvantages are that the aluminum layer and paper cannot be separated, and papermaking cannot be recycled, and the thickness of the aluminum layer is difficult Degradation; laminated paper (second generation), PET / OPP film is laminated with paper after spraying aluminum. It originated in the mid-1990s. Its disadvantage is that PET / OPP film cannot be separated from paper, and it can neither be recycled for paper making nor can it be degraded in soil ; Vacuum aluminum-coated paper (third generation), originated in the late 1990s, the thickness of the aluminum layer of vacuu...
