Cartoning, Packing, Bagging and Wrapping Technology (I)

Boxing, boxing, bagging, and wrapping are actually the filling of containers, boxes, bags, and other containers. Due to the special nature of packaging containers, their packaging techniques and methods also have different fillings from common materials.
Boxes and boxes have long been used as packaging containers for transportation and sales of packaging. Most of them are made of cardboard or corrugated cardboard (also boxes and boxes made of plastic) and belong to semi-rigid containers. Due to their low manufacturing cost and light weight, empty boxes and empty boxes can be folded for storage, transportation, recycling and reuse, or as raw materials for papermaking. Therefore, they are still one of the basic forms of packaging.
Both the wrapping and bagging use thinner flexible materials such as paper, plastic films, metal foils, and composites thereof.
The packaging and bagging materials are simple, the operation is simple, the packaging cost is low, and sales and use are convenient. Therefore, the scope of application is very wide and it is constantly expanding. From solid packaging materials to liquid materials of various viscosities; from small razor blades to paper webs that are nearly a meter in diameter; from a few grams of sachets to dozens of kilograms of sacks of cement and fertilizers. In particular, modern merchandise sales methods and people's lifestyles, such as the rise of supermarkets, fast foods, the development of flexible materials and decorating, printing technologies, and the development of corresponding packaging machines, are rapid and continuous for these two packaging technologies. Land development provides a lot of conditions, they occupy an important position in the packaging field, especially for food and daily necessities packaging.
The boxing technology box refers to a small container such as a toothpaste box, a soap box, a medicine, a stationery and various food boxes. Most of the boxes are made of cardboard, which are used for sale and packaging. There are fashion bottles for loading and then boxes, or small boxes for larger boxes. In short, all belong to the inner package. Most boxed goods are displayed on the shelves at the market and retail stores and eventually reach consumers.
For many years, the development of boxes has been mainly transforming patterns and improving printing and decorating; the boxing technology has been developed mainly from manual operation to mechanization, semi-automation and full automation. The use and function of the box have not changed much.
First, the types of cartons and the types and styles of cartons used are many, but the differences are mostly in the form of construction, opening methods and sealing methods.
1. According to the box-making method can be divided into the following two categories:
(1) The folding box or cardboard is made into a box blank after die-cutting and indentation; or the side edges of the box blank are bonded to form a square or rectangular tube, and then pressed into a box blank, which is then boxed The scene is folded into various boxes again. Both the box blanks and the box blanks are flat, and the purpose is to save space and be convenient for storage and transportation. When loading the box blanks of the cartoning machine, picking and placing is convenient. The folding box is suitable for mechanized mass production. The folding box is divided into a cartridge box and a shallow tray box from the perspective of use.
(2) The fixed box is made into two parts, the box and the cover, or the cover is made of flexible paper and cloth made of flexible and hinged together with the box. The fixed box, regardless of the box and lid, becomes a unitary body when it is made, and cannot be folded or crushed. Empty boxes are bulky and inconvenient to store and transport. Regardless of sticking by hand or making boxes by machine, the productivity is low and the cost is high. The advantage of the integral box is that it can be made of thick cardboard and has good protection for the product. It is suitable for brittle and fragile products, such as medicinal injections, glassware, etc. In addition, various decorative materials can be used to paste into a luxurious appearance. Boxes for gifts, souvenirs, and valuable crafts.
2. There are many factors involved in the selection of packaging containers for use in the carton. Here, the following points are proposed for the selection of the structure of the cartridge:
(1) When the product is easily put into or out of the narrow section of the box, such as toothpaste, medicine bottle, etc., the cartridge type box can be used, and the cover sheet is used for the plug-in type sealing, which is convenient to use; if the goods are heavy or have a sealing requirement When the cover sheet is used, the cover sealing method should be used; if the product is dispersed particles or individuals, it is easy to loosen due to loosening of the cover sheet, such as soap tablets, push pins, etc., and the tabs and cover sheets should use buckled structure. .
(2) When the goods are not easy to put into or out of the narrow face of the box, such as cakes, biscuits, clothing and arts and crafts, etc., the shallow disk type box should be used.
(3) In order to promote goods or make it easier for customers to understand the product, a box with a transparent window should be properly selected. Such as toothbrushes, jewelry and birthday cakes.
Second, the boxing method The most convenient boxing method by hand-boxing method is hand-boxing, which does not require equipment and maintenance costs. However, it is slow, labor productivity is low, and commodities that require high requirements for foods, medicines, and other sanitary conditions are prone to contamination. It applies only if the economic conditions are poor and there is cheap labor.
