Abstract

The invention discloses a uniaxially-tensioned high speed printing matt PE film and a production technology thereof. The matt PE film comprises a corona layer, a middle layer and a heat sealing layer, and the corona layer, the middle layer and the heat sealing layer respectively independently comprise blown film grade bimodal metallocene polyethylene. The uniaxially-tensioned high speed printing matt PE film has the advantages of guaranteeing of high haze, low crystallization point and high stiffness, and can meet the demands of high speed printing.

Description

technical field [0001] The invention belongs to the field of packaging, and in particular relates to a unidirectional stretchable high-speed printable matte PE (polyethylene) film and a production process thereof. Background technique [0002] With the change of people's aesthetic concept and the improvement of consumption concept, the demand for the surface characteristics of packaging materials is also diverse. The matting film is a new type of packaging film developed under this requirement. It is used for food, gifts, candies, etc. The packaging of , maternal and child products, etc., as well as the printed paper of large outdoor advertisements and the cover of hardcover books, have good shelf and advertising effects, giving people a sense of three-dimensionality and luxury, and stimulating the desire to buy. [0003] According to the surface gloss of the product, the product is divided into three categories: glossy, matte and matte products: glossy products with a gloss...
