Abstract

The invention provides a label film with high transparency and high gloss, a preparation method thereof and a label, and belongs to the field of label films. The label film with the high transparency and high gloss is prepared from, by mass, 50-60% of HDPE, 10-20% of mLLDPE and 20-40% of LDPE. The preparation method for the label film with the high transparency and high gloss comprises the following steps that raw materials are mixed at the ratio after dedusting, and then fused and plasticized to obtain flowing resin; the flowing resin passes through a dandy roll, and is cooled and shaped; then, trimming and corona treatment are performed, and finally, rolling is carried out to obtain the label film with the high transparency and high gloss. The label is prepared by using the label film with the high transparency and high gloss. The provided label film with the high transparency and high gloss has good transparency and gloss.

Description

technical field [0001] The invention relates to the field of label films, in particular to a highly transparent and high-gloss label film, a preparation method and a label thereof. Background technique [0002] As the commodity economy becomes more and more developed, labels have become a product with a wide range of applications and a large amount of use. However, with the increase of demand, people are no longer satisfied with labels with basic functions, and have higher and higher requirements on the appearance, color, and whether they can attract consumers' attention. [0003] Label film is the main component of the label, and its performance greatly affects the final effect of the label. The transparency and gloss of the label film are the indicators that manufacturers pay most attention to. [0004] People have done a lot of research on transparency and gloss, but it is difficult to achieve high transparency and high gloss while ensuring the mechanical properties of ...
