Paper tube packaging has good market prospects for development and design and can be used as a substitute for metal materials, laminated glass, porcelain plastic packaging containers. Compared with this kind of plastic packaging container, its key characteristics are: because the paper is the key raw material, it is very easy to purchase and solve; it can maintain the quality of properties, moisture-proof, waterproof, and has the necessary practical effect of heat insulation; it is odorless, non-toxic, reliable, and is very suitable for food packaging materials; it can fill all kinds of goods, and the noise is small when filling; it can be used for packaging;
It can bear the forced draft fan and air pressure, and can be used for a vacuum pump or nitrogen filling packaging; it has a variety of modeling design structures, and can carry out color printing on the surface, which has the excellent practical effect of window display; it is light in quality, only 40% of the iron barrel, and the commodity circulation is very easy, convenient to use, and the price is low.
The main use of paper tube packaging for environmental protection is very common. It can be used to hold all kinds of liquid food, such as juice, wine, purified water, milk, etc., except that it is commonly used to hold powdery liquid food, such as chocolate powder, tea leaves, sugar, salt, oatmeal, freshly ground coffee and all kinds of solid drinks. It can also be used to hold health products, fuel food, refrigerated extracted food, etc. For example, about 86% of the extracted citrus juice in the UK is packaged in composite paper cans. About 60% of the tea drinks in Japan are packaged in composite paper cans with aluminum easy-to-pull lids.
In addition, paper can packaging can also be used in * * type packaging design, such as vacuum packaging bag, including "dry" vacuum packaging bag of freshly ground coffee, baby milk powder, and peanut kernel, and "wet" vacuum packaging bag of concentrated juice and seasoning; working pressure packaging, including nitrogen-filled Chinese fast food packaging materials and aerated beverage packaging. But paper can package are not suitable for cold storage and hot processing food packaging.
Where is the key to the paper tube?
1. Core unwinding raw materials, such as handkerchief paper core, transparent rubber sealing paper core, tin foil paper bag paper core.
2, packaging bags, such as tea cans, perfume cans, French fries, and some of the food products of the circular packaging box.
3. Maintain paper packaging, such as calligraphy and painting paper tube, LED lamp paper tube, chemical raw material paper barrel
There are two key categories of paper tubes:
The paper tube production process is divided into two categories
1. The application of belt side spiral coil also includes the use of tooth pressure agent type
2. Two is very simple, the application of abrasive straight-pull roll type
I think there are also many aspects of the main uses of paper tubes. At present, they are mainly used in national high and new technologies such as engineering construction and building houses.
