Abstract
The invention discloses a special BOPP film for a cold transfer cigarette label paper and a preparation method of the BOPP film. A direct co-extrusion composite way of a three-layer structure is adopted, and according to the formula, each layer of raw material comprises the following components in parts by weight: 85-99 parts of upper surface copolymer polypropylene, 1-15 parts of slipping anti-sticking agent master batch, 55-80 parts of core layer homopolymer polypropylene, 15-30 parts of stiffening agent maser batch, 5-15 parts of slip-antistatic agent master batch, 65-89 parts of lower surface copolymer polypropylene, 10-20 parts of slipping agent master batch and 1-15 parts of anti-sticking agent master batch. The produced BOPP film has relatively wide operation applicability, good stiffness and high elasticity modulus by optimal raw materials and process, and is capable of reducing the contact surface of the BOPP film and the cold transfer cigarette label as a special package film for the cold transfer cigarette label paper, and therefore, the film is effectively prevented from being fitted with the cigarette label to avoid generating the 'watermark' phenomenon during packaging, and compared with an existing BOPP film, the BOPP film has the advantages that the packaging efficiency and the packaging quality are obviously improved.
Description
technical field [0001] The invention belongs to the technical field of BOPP film processing, and in particular relates to a BOPP film suitable for cold-transfer cigarette trademark paper matching hard box small pack cigarette packaging and a preparation method thereof. Background technique [0002] After years of development, the cold transfer printing process is gradually being applied to cigarette label printing. In the second half of 2009, some domestic cigarette companies began to use this new type of cigarette label. Because it has obvious advantages over traditional cigarette labels in terms of material cost, and can maintain the characteristics of traditional cigarette labels in terms of packaging appearance. Therefore, it is foreseeable that this new type of cigarette label will have great potential in the future development of the tobacco industry, representing the development direction of the new type of cigarette label. [0003] However, due to the large differe...
