Embodiment

[0032] The CPP film book cover production process includes the following steps:

[0033] Step 1, batching, weighing and batching the material;

[0034] Step 2, feeding and stirring, put the materials into the hopper mixer in turn, put the materials with a small amount in the middle section, the speed is 30 rpm, put the prepared materials into the feeding port in turn, and put the materials with a small amount in the middle, Make sure that the dispersion is uniform, and continue to stir for a certain period of time after all are put in. Continue to stir for 15 minutes. During the stirring process, foreign matter falls into the mixer. It is necessary to stop stirring for processing. Always pay attention to the supply of materials, and there should be no shortage of materials.

[0035] Step 3, the material is extracted and melted, the stirred material is pumped into the CPP casting machine for heating, the heating controller of the CPP casting machine is set, and the heating is ...

Abstract

The invention discloses a CPP thin film book cover production process, relates to a thin film production and processing technology, and aims to solve the problems that the production efficiency is easily influenced during production due to more and more complicated steps of an original book cover manufacturing method, and meanwhile, the edge of a CPP thin film obtained by cutting is sharp, so that people are easily scratched. According to the technical scheme, the method is characterized by comprising the following steps that firstly, materials are weighed and mixed; step 2, feeding and stirring: sequentially feeding the materials into a hopper stirrer, feeding a small amount of materials at a middle section, and continuously stirring for a certain time after all the materials are fed; 3, pumping and melting the materials, and pumping the stirred materials into a CPP casting machine for heating; and 4, film blowing, wherein after the temperature in the CPP casting machine reaches the set temperature, material injection and film blowing are started. Production can be carried out through thermal shaping, the production steps can be reduced, the working efficiency is improved, the edge of the obtained book cover is round, and people are not prone to being hurt when touching the book cover.

Description

technical field [0001] The present invention relates to film production and processing technology, more particularly, to a CPP film book cover production process. Background technique [0002] With the development of science and technology, various kinds of commodities are becoming more and more numerous. As a packaging material, CPP film is widely used in the packaging of food, daily necessities and electronic products because of its good isolation effect on water vapor and peculiar smell and high degree of transparency. , which has high requirements on the sealing fastness and sealing strength of the CPP film. [0003] At present, the production method of CPP film is: mixing various raw materials according to the formula and stirring them evenly, and then subjecting the mixed raw material mixture of each layer to extrusion plasticization, extrusion casting, cooling molding and other steps respectively. For the finished film, before the book cover is finally formed, two CP...
