Production and manufacturing method of renewable environment-friendly paper-plastic composite bag

Abstract

The invention relates to a production and manufacturing method of a renewable environment-friendly paper-plastic composite bag, and further particularly relates to a production and manufacturing device of the renewable environment-friendly paper-plastic composite bag. The production and manufacturing device specifically comprises a device seat, a gluing feeding mechanism, a glue uniformizing mechanism, a compressing composite mechanism and a cold-drying glue setting mechanism; two side vertical plates are parallelly arranged on the device seat; and the gluing feeding mechanism, the glue uniformizing mechanism, the compressing composite mechanism and the cold-drying glue setting mechanism are sequentially arranged between the two side vertical plates. Through the device involved in the method provided by the invention, a paper tape and a thin film tape can be quickly compressed to be composited, compositing is full and reliable, and the compositing quality is higher; and a cold-drying process is increased, thus direct winding after compositing is completed is facilitated, and the finished product quality of raw materials of the paper-plastic composite bag is guaranteed.

Description

technical field [0001] The invention relates to the technical field of composite bag processing, and specifically proposes a method for producing a recyclable and environmentally friendly paper-plastic composite bag. Background technique [0002] Paper-plastic composite bags are suitable for vacuum packaging or general packaging of food, electronic products, chemicals, medicines, tea, precision instruments and cutting-edge defense products. Paper-plastic composite bags are widely used in the packaging field, mainly made of packaging paper and used for Composed of composite transparent film, it is especially convenient for bulk powder and granular materials. It has the characteristics of high strength, good water resistance, beautiful appearance, and easy loading and unloading. It is the most popular and practical general packaging material; paper-plastic composite bags are divided into Polypropylene two-in-one bag, polypropylene three-in-one bag, polyethylene two-in-one bag,...

AI Technical Summary

Problems solved by technology

[0003] In the production and processing process of paper-plastic composite bags, paper-plastic composite rolls are the raw materials for the production and processing of paper-plastic composite bags. Paper-plastic composite rolls are mainly composed of paper tape and plastic film (plastic film can be transparent film or Printed plastic film) is bonded by glue (composite media) to form a paper-plastic composite coil. In the production and processing process of the traditional paper-plastic composite coil, it is easy to have coating The problem of uneven glue, in addition, after the paper-plastic composite coil is formed and compounded, the glue cannot be cured in time and the roll is directly rewound, which affects the quality of the paper-plastic composite coil
