New features of paper packaging technology Modern technology has been applied to the printing and packaging field, which has made many packaging and printing processes easier and more scientific and rational. Single-layer materials develop in the direction of multi-layer materials; Offset printing, gravure printing, flexo printing, screen printing, etc. coexist, among which flexo printing will grow fastest; single sheet to web and single-machine orientation The development of production direction, the realization of complete sets of equipment supply; comprehensive application of various related new technologies to continuously optimize the entire production system; more and more increasingly subject to increasingly stringent environmental protection and health standards.
In the processing of packaging and post-printing processes, it is more scientific and applicable, and the performance and effectiveness of packaging have changed significantly. For example, in the past, wax coating and film lamination in the packaging surface treatment have been gradually replaced by surface gluing (spray-bonding), and anti-counterfeit packaging production technology has shifted from partial printing or production to monolithic printing and production. Security. Paper packaging materials have the characteristics of environmental protection, recycling, cost saving, etc. With the increasing international environmental protection requirements for packaging materials, paper packaging materials are the preferred packaging materials, and paper packaging materials have another one in addition to environmental protection. The characteristic is that it can quickly achieve the goal of cost savings through rapid inspection through commodity inspection.
New requirements for paper packaging technology In fact, different packaging users have different requirements for corrugated boxes. Generally use a large area of ​​printing, and mainly four-color water-based printing. Because of different contents, the requirements for the strength of the board vary greatly. The content is fragile biscuits, cakes, convenience foods, etc. The requirements for the strength of the cardboard are quite high; the contents are water, beverages and other products, and the strength requirement for the cardboard is relatively low.
The requirements for food and drink are different. The rear packaging of food and beverages generally adopts an automatic packaging line, so the requirement for the flatness of the cardboard is high. Uneven cardboard can easily cause jams and affect productivity. The problem of flatness in cardboard can only be solved by matching the paper and updating the production line. Currently, the food and beverage industry has formed several major categories for the use of facial tissues and the selection of processes: general foods mainly consisting of fine white paper; high-grade pre-printed packaging mainly consisting of lightweight coated white paper; mainly kraft paper The general food packaging; Japan, Taiwanese food companies mainly consisting of Japanese yellow noodle paper corrugated carton packaging.
New breakthroughs in paper packaging technology For the food packaging industry, especially for seafood and other aquatic product packaging, due to preservation needs, in the preservation and transportation process requires refrigeration treatment, in order to prevent the moisture absorption of the packaging damage, the prevention of penetration and wet strength Higher requirements.
According to reports, the “Anti-permeation Liner Board Development Project†recently selected by the Jingxing Association for Science and Technology has been researched and discussed by the Pinghu Science and Technology Association. In conjunction with the on-site tracking investigation, it has finally won the second prize of the 2014 Pinghu City Jinqiao Engineering General Project.
According to the company's introduction, anti-seepage paper is used to optimize the technical process in the production process to improve the wet strength, anti-permeability and other physical indicators into paper, in order to achieve the high-end packaging requirements for waterproof, anti-seepage, preservation and other special features to meet customers And market demand.
The marketization of this technology has undoubtedly opened up new opportunities for the carton factory. With the development of the Internet and e-commerce applications to expand naturally from the urban to the rural areas, fresh, frozen, fresh food and other food areas will also gradually open, and this project will technically address such packaging boards with special needs.
The mixing arm drives the mixing blade to force the mixing of the material in the tank body, the mixing effect is very strong, and the mixing quality is better.There are two steel bearing protection circles between the mixing arm and shaft.to prevent coarse sand.In the steel circles there is a airway. When certain pressure of air goes though it,a pressure protection mat will be formed between the interface of the mixing arm and shaft to prevent water and mud from close to shaft head and prolong the service life of the mixer.
