At present, high-shrinkage plastic films have entered the domestic packaging market in large quantities, and are mainly used for shrink sleeve labels, bottle caps and cap closures, security tapes, and bundle packaging. Relevant experts estimate that the demand for shrink labels may increase by about 20% per year over the next five years.
In addition to being used as a label, high-shrinkage plastic films can also be applied to external packaging. Because it can not only protect the product, but also can be used as a beautifully printed outer package to increase the shelf life of the product. At present, more and more packaging companies use printed shrink film instead of traditional transparent film, because the former can improve the appearance of the product performance and facilitate product advertising. In order to meet market demand, equipment suppliers are also working hard to develop new equipment to produce shrink films that meet market needs. For example, the LSK and SK series production lines produced by Italy SMI can produce a variety of printed shrink films, which can be operated in single, double and triple passes. The packaging process is completed in stages.
