Embodiment 1

[0027] 49.5 parts by weight of polypropylene, 35 parts by weight of petroleum resin C5, 15 parts by weight of petroleum resin C9, and 0.5 parts by weight of compatibilizer A are premixed and granulated through a twin-screw extruder. The rigidity masterbatch manufactured according to the above-mentioned raw material formula and process conditions is used to produce 15 micron BOPP shrinkable cigarette film, its physical performance index is shown in Table 1, and the trial effect in the cigarette factory is shown in Table 1.

Embodiment 2

[0029] 49.5 parts by weight of polypropylene, 30 parts by weight of petroleum resin C5, 20 parts by weight of petroleum resin C9, and 0.5 parts by weight of compatibilizer A are premixed and granulated through a twin-screw extruder. The temperature and process parameters of the twin-screw extruder are set basically the same as those in Example 1. The stiffening masterbatch was manufactured to produce 15 micron BOPP shrinkable cigarette film. The physical performance indicators are shown in Table 1, and the trial results in the cigarette factory are shown in Table 1.

Embodiment 3

[0031] 49.5 parts by weight of polypropylene, 35 parts by weight of petroleum resin C5, 15 parts by weight of petroleum resin C9, and 0.5 parts of compatibilizer are premixed and pelletized through a twin-screw extruder for rapid cooling. C9 type petroleum resin is composed of a series of amorphous oligomers, and the melt is particularly viscous. It is relatively difficult to granulate after the mixing ratio of C9 type petroleum resin is increased. In order to ensure the large-scale production of this product, the existing cooling method has been modified. A set of quick cooling pelletizing system is designed to ensure the normal pelletizing process.

[0032] The temperature and other process parameters of the twin-screw extruder are set basically the same as those in Example 1, and the stiffening masterbatch is produced for the production of 15 micron BOPP shrinkage cigarette film. The physical performance indicators are shown in Table 1, and the trial results in the cigarette...

Abstract

The present invention provides a reinforcing master batch specialized for 15 millimeter BOPP shrinkage tobacco film. Through selecting and mixing C5 and C9 petroleum resins and adding an appropriate compatilizer proportionally, high effect and stable quality of the manufactured reinforcing master batch are obtained. The reinforcing master batch is used for manufacturing the 15 millimeter BOPP shrinkage tobacco film. Not only is requirement for attractive appearance of high-grade tobacco package and normal use on machine satisfied, but also amount of the used packaging film is reduced. The amount is reduced for about 25%. The amount of the generated garbage is reduced, and a purpose of environment protection is obtained.

Description

technical field [0001] The invention relates to a 15-micron BOPP shrinkable cigarette film special stiffening masterbatch. Background technique [0002] Biaxially oriented polypropylene cigarette packaging heat shrinkable film, referred to as BOPP shrinkable cigarette film, is a high-grade BOPP film. In the process of producing BOPP shrinkable cigarette film, a large amount of stiffening masterbatch is required. The stiffening masterbatch is a modified material. It is made by mixing homopolymer polypropylene and modified stiffening material in a certain proportion, which can significantly increase the heat shrinkage rate of the film, improve the haze and gloss of the film, strengthen the barrier property of the film, and meet the requirements of the high-end cigarette packaging process. Good appearance requirements required. [0003] At present, the stiffening masterbatch on the market is mainly used to produce 20 micron BOPP shrinkable cigarette film. In order to achieve t...
