Talk about the application of spray aluminum paper in wine labels

Vacuum spray aluminum paper has been popular in the United States and Europe since the 1980s. It has won the favor of the packaging industry with its noble and beautiful metal texture, stable and reliable printing performance, and degradable and recyclable environmental protection properties.

Compared with ordinary paper labels, sprayed aluminum paper labels are more sparkling, attract more attention, deliver high value, high freshness and high quality information to consumers, plus it has the advantages of smoothness, lightness, durability, etc. The printing presses, embossing machines, high-speed die-cutting machines, and labeling machines are bottled, and are therefore widely used as high-end labels for consumer products such as beer.

At present, 30% of domestic beer labels use aluminum spray paper, which is mainly concentrated in some large breweries or major beer brands. Since 2000, Budweiser, Sandeli and Tsingtao Beer have begun to use aluminum spray paper on their wine labels. The price was relatively high at first, but with the introduction of low-weight materials and imported aluminum spray paper The price of aluminum spray labels is becoming more and more reasonable.

Wine label spray paper purchase instructions
First of all, understand the current domestic aluminum spray paper suppliers and aluminum spray equipment. At present, the domestic advanced direct-plating aluminum sprayer is mainly based on Germany's lycra, with an annual output of nearly 1 million tons of aluminum spray paper, and more than 100,000 tons are produced by Shanghai Zijiang, Shenzhen Haishen and Jiangsu Daya, etc. The average price is 29,000 yuan per ton; well-known foreign brands have the United States Wei Mei, the United Kingdom has been constant, the price slightly higher than the domestic paper, but the quality and the relatively high rate of success.

Secondly, the aspects that should be paid attention to when purchasing aluminum label bottom paper. The performance of beer labels includes wet tensile strength, tear resistance, curl, reactivity with water, back-absorbency and washability (easy to wash or not); brand image features include whiteness, wetness Transparency, gloss, anti-wear properties and printability. The wet tensile strength of a 70-gram label paper suitable for offset printing should be 12N/15M; the transverse and longitudinal tear resistance should be not less than 280mN and 260mN, respectively; and the printing conditions under 50% relative humidity and 85% relative humidity should be applied to the labeling workshop. The degree of curling corresponds to the maximum value of the edge curl of the paper is 14mm; after the paper is exposed to water (glue or wet bottle), the reaction is violent, it will produce labeling problems, and low reactivity, poor reactivity; back water absorption should be 14g/ In the m2+3 interval, the ideal opacity of wet is 74; the standard for evaluating the glossiness is Baihao, Huanghe, the minimum whiteness value of the wine label paper must not be lower than 87%; the glossiness test of the spray paper (20° angle) High gloss is good, low gloss - matt is poor; offset adaptability is tested by pulling speed, gravure test pigment color point.

Domestic beer standard aluminum spray paper adopts high-wet and strong backing paper, which are basically imported from abroad. Suppliers include Aoslon of France, Saatchi of Denmark, and Sappi of Italy. The price of backing paper is approximately US$ 1,400 per ton. .

Finally, it should be emphasized that, in beer labeling, gram weight and back moisture absorption rate are two important indicators of aluminum spray wine labels, which directly affect the cost and labeling performance of labels. From the actual situation of the printing press, offset printing with aluminum paper is better than 70 grams, gravure is best less than 70 grams. Offset printing is suitable for printing in small batches. The use of gravure for long-length labels in large batches not only has stable color, but also has a better labeling effect.
