Heat shrinkable film packaging can effectively reduce costs

Heat shrinkable film packaging can effectively reduce costs. Release time: 2019-12-20 　　 Ordinary packaging grade PVC shrink film, can be made into tubular film, L-shaped half-fold film according to requirements, and can be processed into tube bags, flat bags, although ordinary packaging levels PVC shrink film can also be used for printing, but the printing effect is not fine, and the number of colors that can be printed is small. Generally, it is printed with one or two colors. Stretch film packaging makes the packaged items evenly stressed to avoid damage to the items due to uneven force, which is not possible with traditional packaging methods (bundling, packing, tape, etc.). Compression fixity: The product is wrapped and packaged by the retraction force of the stretch film to form a compact, space-saving unit, so that the pallets of the product are tightly wrapped together, which can effectively prevent the product during transportation The mutual dislocation and movement, and at the same time, the adjustable stretching force can make the hard products stick tightly and shrink the soft products, especially in the tobacco industry and the textile industry, which has a unique packaging effect. Cost saving of heat shrinkable film: The use of stretch film for product packaging can effectively reduce the cost of use. The use of stretch film is only about 15% of the original box packaging, about 35% of the heat shrinkable film, and about 50% of the carton packaging. At the same time, it can reduce the labor intensity of workers, improve packaging efficiency and packaging quality. The heat shrinkable film label is a part of the label market, and it is now in rapid growth. The market share is expanding. It is estimated that the annual increase rate is about 15%, which greatly exceeds the annual increase rate of about 5% in the general label market. Become a highlight of the label printing industry. It is predicted that the domestic heat shrinkable film market will increase at a rate of more than 20% in the next five years. The food industry is a big shopping mall for shrink packaging. Heat shrinkable film is widely used in the packaging of various fast foods, lactic acid foods, beverages, small foods, beer cans, various alcohols, agricultural and sideline products, dry foods, and souvenirs. At present, the customer base of the shrink film label market is mainly some large fast-moving consumer goods companies, such as Procter u0026 Gamble, Unilever, Shanghai Jahwa, etc., whose products are large in volume and demand long-run printing. The initial investment of gravure printing is high, but the gravure printing plate has high printing endurance and relatively low cost which makes it the primary choice for shrink film printing. And the graphic part on the printing plate is recessed, so a rich ink layer, gorgeous color and rich layers can be obtained.　　 Heat-shrinkable polyester film is not only used as shrink label, but now it is also used for outer packaging of daily commodities. Because it can not only protect the packaged items from shock, rain, moisture, and rust, but also make the product win users with its beautifully printed outer packaging, and it can well show the good image of the manufacturer. Nowadays, more and more packaging manufacturers use printed shrink film to replace traditional transparent film. Because the printed shrink film can improve the appearance of the product, it is conducive to the advertising of the product, and the trademark brand can have a deep impression in the hearts of consumers. Heat shrinkable film mainly uses unit type gravure printing machine. Now such machines are equipped with automatic tension control system and automatic color registration control system. According to the error between the measured color registration marks, the uncoiling area, printing area and winding area are automatically adjusted. Tension to ensure the stability of the tension during the printing process and the accuracy of the final overprint. Compared with stacking and unit type flexographic printing presses, flexographic heat shrinkable film is more suitable for CI type flexographic printing presses. This is because each color group shares an impression cylinder during the printing process, and the printing material and impression cylinder are tight. The tight fit, the change of tension is small, so that the stretching deformation of the material is small, and the registration accuracy is high. There are four main types of inks for shrink film printing: solvent-based inks, water-based inks, cationic UV inks and free radical UV inks.
